PLEASSEEEEEEEEE Solve for x ax^2-2ax+(a+1)=0

Let x and y be the two numbers we are trying to find.

'One number is 9 more 3 times another' is equivalent to x=9+3y

'Their product is 9 more than 3 times their sum' is equivalent to xy=9+3(x+y)

We have two equations and two unknowns; therefore, we can solve the problem

Solve it as shown below

The solutions are (21,4) and (0,-3)

Mark has 35 unique combinations to choose from, so can he co go 5 weeks with this set of clothes

Number of pants in Mark's closet = 5

Number of shirts in Mark's closet = 7

Combinations are ways to choose elements from a collection in mathematics where the order of the selection is irrelevant. Let's say we have a trio of numbers: P, Q, and R. Then, combination determines how many ways we can choose two numbers from each group.

He can choose amongst the pants in 5 ways, similarly, he can choose among the shirts in 7 ways

Total number of combinations = 5*7 = 35 unique combinations

So, if he wears one combination each day he can last 35 days or 5 weeks, without buying new clothes

Answer: Well we can look at whether or not cubes may or may not equal the same by using volume and surface area, where the volume can be used as x^3 and the surface area x^2, but the reason why polynomials can help us a great deal in world problems is whether or not measurements are accurate, or just in general for solving big math equations.

Answer:[tex][x{-\frac{5}{2}] ^{2} +\frac{-12}{25}[/tex] is in the form [tex][x+p]^{2} +q[/tex]

Step-by-step explanation:

Here given is [tex]x^{2} -5x+3[/tex].................................eq [1]

now we know that  [tex][x-\frac{5}{2}] ^{2}[/tex]= [tex]x^{2} -5x+\frac{25}{4}[/tex]............eq [2]

now add and subtract [tex]\frac{25}{4}[/tex] in eq 1

 [tex]x^{2} -5x+3+\frac{25}{4} -\frac{25}{4}[/tex]

 [tex]x^{2} -5x+\frac{25}{4}+3-\frac{25}{4}[/tex]

Answer:  The answer is 5 shirts

Step-by-step explanation:

8x + 6 = 50

subtract 6 from each side:

8x +6 (-6) = 50 (-6)

8x=44

divide by 8:

8x/8=44/8

x=5.5

round to single shirts:

x=5 shirts

Answer:

Step-by-step explanation: you have to divide 50 by 8 then get your answer of 6.25, but you also have to consider two things; the extra $6.00 flat fee, and you cant buy 6.25 shirts, so what we do is multiply 8 times 6 to get 48, but we have to consider the extra $6.00, so you take away 8 which gives you 5 shirts, plus the shipping fee so in all he can buy 5 shirts.

The ordered pairs lie on the graph of the exponential equation is

Exponents are used in exponential functions, as the name indicates. But take note that an exponential function does not have a constant as its base and a variable as its exponent (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function). One of the following forms can be used for an exponential function.

According to its definition, a fundamental exponential function has the formula f(x) = [tex]b^x[/tex], where b is a constant and x is a variable. The exponential function f(x) = [tex]e^x[/tex], where "e" is "Euler's number," and e = 2.718, is one of the most well-known ones. An exponential function may incorporate a constant if we expand the potential of various exponential functions.

Given function:

f(x) = 25 [tex](2.2)^x[/tex]

Now, taking x=0

y = f(x) = 25

and, x=0.5

y= f(x) = 37.08

and, x = 1

y = 55  

and, x=2

y = 121

So, the ordered pairs lie on the graph of the exponential equation is

2. The given function is [tex]f(x)= (3/8)^x[/tex]

Now, as per the graph As x decreases without bound, the graph of f(x) approaches y = 1.

Or,  As x decreases without bound, the graph of f(x) increases without bound.

To get the answer for X we have to subtract 16 from 4 which gives us 12

X=12

Hope this helps.

Answer:

4+X= 16

X=16-4

X=12

*To find X , you need to minus 16 by four. That is because you have to move (+4) to the other side (change sides,change signs). So (+4) becomes (-4) so 16-4 =12

11 miles he run per day, Monday-Friday.

The unitary technique involves first determining the value of a single unit,  followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Total distance travelled = 60 miles.

On Saturday= 5 miles

Sunday was off

So, from Monday to Friday he travelled

=60 - 5

= 55 miles.

and, per day he run

= 55/5

= 11 miles

The length of the park not counting the path is 98 yards

The formula for determining the area of a rectangle is expressed as;

Area = lw

Where;

From the information given, we have that;

The dimensions of the path having a width of 1 yard path around it are

(L+2) x (W+2)

We have to add 2 to the length and width because there will be a 1 yard path on all 4 sides of the rectangle

Given that the area is 4200 square yards; the original width is 40 yards

Now, substitute the values into the formula, we have;

Since Area = LW

4200 = (L+2)(W+2)

4200 = (L+2)(40+2)

Add the values

4200 = (L+2)(42)

expand the bracket

4200 = 42L + 84

collect like terms

4116 = 42L

Make 'L' the subject of formula

L = 98 yards

What is congruent triangle?

Two figures are said to be "congruent" if they can be placed perfectly over one another. Both of the bread slices are the same size and shape when stacked one on top of the other.

Congruent refers to having precisely the same form and size.

If all three sides of two triangles are the same, they are said to be congruent.

If we have a side, an angle between the sides, and then a second side that is congruent, we know they are congruent. In other words, side, angle, side.

Answer:

5 inches

Step-by-step explanation:

Hello!

The volume of a cube is simply the side length cubed, or the side lengthed multiplied by itself 3 times.

So, to find the edge, we can find the cube root of 125 to find that measure.

The edge is 5 inches.

The surface area of the can is 220cm².

The height of the can is 10cm, and the diameter is 7cm.

height (h) = 10cm

radius(r) = 7/2 cm

The formula to find the surface area of the can = 2πrh

                                                                              = 2 × 22/7 × 7/2 × 10

                                                                              = 220cm²

Therefore the surface area of the can is 220cm².
