What is the slope of a line that is parallel to the given line
Answer:
-3/2
Step-by-step explanation:
The slope of a line is calculated by finding the rise over run of two points on the line. In this case, I use the points (-3, 4) and (1, -2). Then, I use the formula of [tex]\frac{y_{2} - y_{1}}{x_{2}- x_{1} }[/tex] to find the slope. If 4 is [tex]y_{2}[/tex], -3 is [tex]x_{2}[/tex], 1 is [tex]x_{1}[/tex] and -2 is [tex]y_{1}[/tex], then,
[tex]\frac{4 - (-2)}{ -3- 1 } = \frac{6}{-4} = \frac{3}{-2}[/tex]
Furthermore, the slope of a parallel line is always the same as the given line. Therefore, the answer is -3/2.

Answer:
x = 2 and y =
Step-by-step explanation:
y = 2x - 1
y = -x + 5
2x - 1 = -x + 5
2x + x = 5 + 1
3x = 6
x = 6/3
x = 2
y = 2(3)-1
y = 5

20% of a number is 17. Find the number.
Answer:
85
Step-by-step explanation:
20% x X = 17
20/100 x X = 17
X = 17 x 100/20
= 17 x 5
= 85
the number is 85
Answer:
17 is 20% of 85
Step-by-step explanation:
20%= 1/5 so 17 = 1/5 of that number if you multiple 17 by 5 that would equal 85.
17 is 20% of 85

Answer:
Option 4) y - 1 = -2(x - 0)
Step-by-step explanation:
Given the slope, m = -2, and the y-intercept, (0, 1):
Substitute these values into the following point-slope form:
y - y1 = m(x - x1)
y - 1 = -2(x - 0) ← This is the point-slope form given the slope, m = -2, and the y-intercept, (0, 1).
Therefore, the correct answer is Option 4: y - 1 = -2(x - 0)

Amy contributes $50 per month into the Lincoln National Bond Fund that earns 7.26% annual interest.What is the value of Amy’s investment after 25 years?
Answer:
Inc Interest : $16,089
Step-by-step explanation:
1. Let's turn $50 a month into a year, so 50 * 12 = $600
2. Including the annual interest, which is $43.56 out of the $600
3. Add them together, which will be 43.56 + 600 = 643.56
4. Multiply it by 25 to get the full 25 years and you're done!
The value of Amy's investment after 25 years will be $140.75.
What is simple interest?Simple interest is calculated just on the loan's principal amount, whereas compound interest is calculated on both the principal and the cumulative interest. The straightforward crediting of cash flows related to an investment or deposit is referred to as "simple" interest.
Given that, Amy contributes $50 per month to the Lincoln National Bond Fund which earns 7.26% annual interest.
The investment after 25 years will be calculated as,
SI = ( P x R x T)/100
SI = ( 50 x 7.26 x 25 ) / 100
SI = $90.75
The total investment will be calculated as,
A = $90.75 = $50
A = $140.75
Therefore, the value of Amy's investment after 25 years will be $140.75.

determine the intercepts of the line 4x-3y=17
Answer:
x-intercept = 17/4 and y = -17/3
Step-by-step explanation:
To find the intercepts: set x = 0 for the y-intercept and solve the equation and set y =0 for the x- intercept and solve the equation.
To
4x - 3y = 17
4(0) - 3y = 17
0 - 3y = 17
y = 17 /-3
y = -17/3 = -5 2/3 y-intercept = -5 2/3.
The ordered pair on the graph is (0, -17/3)
4x - 3(0) = 17
4x - 0 = 17
4x = 17
x = 17/4 x-intercept = 17/4
The ordered pair on the graph is (17/4, 0)

Answer:
[tex] \frac{17}{40} [/tex]
Step-by-step explanation:
[tex] \frac{4}{5} - \frac{3}{8} [/tex]
First, find the common denominator
So we multiply 4 by 8, and get 32
Then we multiply 3 by 5, and get 15
Next we give both terms new denominators 5 × 8 =40
So now our fractions look like this:
[tex] \frac{32}{40} - \frac{15}{40} [/tex]
Now...that our denominators match we can simply
subtract the numerators
32 − 15 = 17
Thus the answer is:

How do you compare exponential functions??
I really don't understand, also giving brainliest!!
Answer:
You compare it by this
Step-by-step explanation:
Linear functions are graphed as straight lines while exponential functions are curved. Linear functions are typically in the form y = mx + b, which is used to discover the slope, or simply the change in y divided by the change in x, while exponential functions are typically in the form y = (1 + r) x.

possible values for x?
The inequality that represents all possible values for x is x ≥ -27.
What is linear inequality?Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.
Unlike a linear equation it can have a range of values inside an interval.
The given statement can be written in terms of inequality as,
2/3x - 6 ≥ -24
=> 2/3x ≥ -24 + 6
=> 2/3x ≥ -18
=> x ≥ -27
Hence, the inequality expression for the given problem can be written as x ≥ -27.

C-12=-4show me step by step
Answer:
C = 8
Step-by-step explanation:
Rearrange the equation to make C the subject.
C - 12 = -4
Add 12 to both sides.
C - 12 + 12 = -4 + 12
C = -4 + 12
C = 8
Check it:
C = 8
So substitute the new found value into the original equation:
C - 12 = -4
8 - 12 = -4
-4 = -4
All good.
Answer:
C = 8
Hope this helps!
Step-by-step explanation:
C - 12 = -4
C - 12 + 12 = -4 + 12 ( Add both sides by 12 )
C = 8 ( Simplify )
