Using algebraic expression and equation, he invested $2000 in fund b.

An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".

Let x = amount he invested in fund b

If both funds together returned a 4% profit, then the sum of the profit in each investment is equal to 4% of the total investment.

$3000(0.02) + x(0.07) = (3000 + x)(0.04)

Solving for x,

$3000(0.02) + x(0.07) = (3000 + x)(0.04)

$60 + 0.07x = $120 + 0.04x

0.07x - 0.04x = $120 - $60

0.03x = $60

x = $2000

amount he invested in fund b = $2000

Answer:

Equation of line is given as y = mx + c, where m is the slope and c is the y-intercept.

Since slope is 5, equation is y = 5x + c.

Substitute (2,-4) into the equation to find c.

-4 = 5(2) + c

c = -14

Hence equation of line is y = 5x - 14

We may get the same conclusion using either approach, which is that x—5 is a factor of the polynomial.

This will be discussed in further detail below.

Explain, taking into account the fact that, using either method, whether or not we can think of x-5 as a factor in the polynomial based on the given information.

Generally, the equation for the problem is mathematically given as

f(x)=x^3-x^2-17 x-15

Therefore,  If (x-5) is factor of f(x) then at x=5 ,f(x)=0 then apply this

[tex]\begin{aligned}f(x) &=5^3-5^2-17 \times 5-15 \\&=125-25-85-15 \\&=0\end{aligned}[/tex]

In conclusion,Since f(x) is equal to 0 when x = 5, the factor of f is (x-5) (x).

The unknown angles are as follows:

The measures of angle 1 and 2 can be found as follows:

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate angles, vertically opposite angles etc.

Therefore,

∠1 + ∠2 = 180(sum of angle on a straight line)

∠1 = 118(alternate angles)

118 + ∠2  = 180

∠2 = 180 - 118

∠2 = 62 degrees

Therefore,

∠1 = 118 degrees

∠2 = 62 degrees.

The special angle pair relationship between ∠2 and ∠3 is same-side interior angles.

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate angles, linear angles, vertically opposite angles etc.

Therefore, the angle pair relationship between angle 2 and 3 are same side interior angles.

The same-side interior angle theorem states that when two lines that are parallel are intersected by a transversal line, the same-side interior angles that are formed are supplementary.

Supplementary angles are those angles that sum up to 180 degrees. In other words, If the measures of two angles sum up to 180°, they are called supplementary angles.

Therefore, same side interior angles are supplementary angles.

Step-by-step explanation:

Here are all the expanded forms I can think of off the top of my head, sorry if this didn’t help much!

The given pairs of lines have been identified as parallel, perpendicular lines or neither as explained below.

Two lines are parallel if they have the same slope (m), while they are perpendicular to each other if their slopes are negative reciprocal of each other.

The slope in a given equation of a line that is in slope-intercept form, y = mx + b, is represented as "m" in the equation.

1. y = 3x - 7 and y = 3x + 1 both have the same slope (m) of 3. They are parallel lines.

2. y = -2/5x + 3 and y = 2/5x + 8 both have the different slope (m), which are not negative reciprocal to each other. They are neither parallel nor perpendicular lines.

3. The slope of y = -1/4x is -1/4. The slope of y = 4x - 5 is 4. -1/4 is the negative reciprocal of 4. Therefore, the lines are perpendicular.

4. 2x + 7y = 28 can be rewritten as y = -2/7x + 4, the slope (m) is -2/7.

7x - 2y = 4 can be rewritten as y = 7/2x - 2, the slope (m) is 7/2.

-2/7 and 7/2 are negative reciprocals.

They are perpendicular lines.

5. The slope of y = -5x + 1 is -5.

x - 5y = 30 can be rewritten as y = 1/5x - 6, the slope is 1/5.

The lines are perpendicular.

6.  3x + 2y = 8 can be rewritten as y = -3/2x + 4, the slope (m) is -3/2.

2x + 3y = -12 can be rewritten as y = -2/3x - 4, the slope (m) is -2/3.

The lines are neither.

7. The slope of y = -4x - 1 is -4.

8x + 2y = 14 can be rewritten as y = -4x + 7, the slope is -4.

They are therefore parallel lines.

8. x + y = 7 can be rewritten as y = -x + 7, the slope (m) is -1.

x - y = 9 can be rewritten as y = x - 9, the slope (m) is 1.

The lines are perpendicular.

9. They have the same slope of 1/3. They are parallel lines.

10. They have different slopes that are not negative reciprocals, therefore, they are neither.

11. Their slopes are 1/2 and -2. Therefore, they are perpendicular lines.

12. They have the same slope of 3/4. They are parallel lines.

13. They have the same slope of 1. They are parallel lines.

14. Their slopes are -5/4 and 4/5. Therefore, they are perpendicular lines.

15. Their slopes are not negative reciprocals and are not the same, therefore, they are neither.

16. Their slopes are 1/2 and -2. Therefore, they are perpendicular lines.

17. They are both vertical lines, therefore they are neither.

18. x = 1 is a vertical line while y = -8 is a horizontal line that meets perpendicularly. Therefore, the lines are perpendicular.

The new workshop can produce as many as 180 toys each year compared to the old workshop

The approximation of numbers is the estimates of the said number.

This means that the approximation of a number is close to the said number, but it has a slight different value

The given parameters are:

Old capacity = 22,912,546,992 toys per year

New capacity = 4,134,232,638,937 toys per year

The approximate number of times is calculated as

Number of times = New capacity/Old capacity

Substitute the known values in the above equation

So, we have

Number of times = 4,134,232,638,937 toys per year/22,912,546,992 toys per year

Remove the units

So, we have

Number of times = 4,134,232,638,937/22,912,546,992

Evaluate the quotient

So, we have

Number of times = 180.435315217

For every 500 g of reactants, 3.1 g of catalyst were required. The catalyst that was required for 900 g of reactant was 5.58g

The process of catalysis involves introducing a catalyst to chemical reaction to speed up the process. Catalysts are not destroyed during reaction and are unaffected by it. Very little amounts of catalyst are frequently sufficient when the reaction is swift and the catalyst recycles quickly; the velocity of the reaction is greatly influenced by mixing, surface area, and temperature. In most cases, catalysts interact with one or more reactants to produce intermediates that ultimately lead to the final reaction product, regenerating the catalyst in the process.

Homogeneous catalysis, in which all of the components are dispersed in the same phase as the reactant (often a gas or liquid), and heterogeneous catalysis, in which the components are not. It's common to think of enzymes and other biocatalysts as a a third category.

In all branches of the chemical business, catalysis is commonplace. 90% of all chemical compounds manufactured for commercial purposes are thought to use catalysts at some point during the manufacturing process.

The $150 monthly payment on the $3,482.46 credit card loan at 1.55% monthly interest rate gives the number of fewer months it would take to repay the loan if the monthly payment is $200 as 10 months

A monthly interest rate is obtained from an annual interest rate by dividing it by 12.

The monthly payment formula is presented as follows;

[tex] \displaystyle{M = \frac{P \cdot r \cdot (1 + r)^{n} }{ (1 + r)^{n} - 1}} [/tex]

Where;

M = The monthly payments = $150

P = The loan amount = $3,482.46

r = The monthly interest rate = 1.55% = 0.0155

n = The number of periods (monthly payments) = 30

When the monthly payment, M = $150, it takes the career councilor approximately 30 months for the debt to be repaid.

When the monthly payment, M = $200, we have;

[tex]\displaystyle{200 \approx \frac{3482.46 \times 0.0155 \times (1 + 0.0155)^{n} }{ (1 + 0.0155)^{n} - 1}} [/tex]

Which gives;

[tex] \displaystyle{200 \times ((1 + 0.0155)^{n} - 1)= 3482.76 \times 0.0155 \times (1 + 0.0155)^{n}} [/tex]

[tex] \displaystyle{200 \times (1.0155)^{n} - 200 = 53.98278 \times (1.0155)^{n}} [/tex]

[tex]\displaystyle{ 146.017 \times (1.0155)^{n} = 200 }[/tex]

n•ln(1.0155) ≈ ln(1.3697)

[tex] n = \frac{ln(1.3697)}{ln(1.0155)} \approx 20.45[/tex]

The number of months it will take to pay back the loan using a monthly payment of $200 is therefore approximately 20 months

The number of fewer months it takes to repay the loan is therefore;
