Answer:
A(...; 7)
x =-1/5
B(8; ...)
y = 48
The slope is 5
Step-by-step explanation:
y−5x=8
A(...; 7)
We know that y=7, we need to find x
7 - 5x = 8
Subtract 7 from each side
7-7 -5x = 8-7
-5x =1
Divide by -5
-5x/-5 = 1/-5
x =-1/5
B(8; ...)
We know x = 8 we need to find y
y−5x=8
y - 5(8) = 8
y - 40 =8
Add 40 to each side
y-40+40 = 8+40
y = 48
Now we need to find the slope
y - 5x =8
Add 5x to each side
y -5x+5x = 5x+8
y = 5x+8
This is in the form y = mx+b where m is the slope
The slope is 5
Answer:
f(- 3) = - 3
Step-by-step explanation:
To evaluate f(- 3) substitute x = - 3 into f(x) , that is
f(- 3) = - (- 3)² + 6 = - 9 + 6 = - 3
Answer:
Option B and C is correct
Step-by-step explanation:
<h3><u>Given</u>;</h3>
- Priya has 5 pencils, each x inches in length.
- Total length = 34.5 inches.
Now,
5 times x = 34.5
So,
5x = 34.5
34.5 ÷ 5 = x
Thus, 5x = 34.5 and 34.5 ÷ 5 = x are the answer
