Answer:
y = -x + 2
Step-by-step explanation:
If you know the slope and a point on the line, then you can find the equation with an equation:
(y - y1) = m (x - x1)
We have our slope, -1; we have a x1, -2, and a y1, 4, so we're all set to find the equation. Plug in the numbers:
y - 4 = -1 ( x + 2 )
y - 4 = -x - 2
y = -x + 2
Our equation is y = -x + 2

Answer:
there are fourteen 4-point questions and twenty six 2-point questions.
Step-by-step explanation:
Given : A 40-question test has 108 possible points.
There are m 4-point questions and n 2-point questions.
So , equation for total number of questions in the test :
m + n = 40 | 4n + 2n = 108
Multiplying (i) by 2 , we get
2m + 2n = 80
Subtract (iii) from (ii) , we get
2m = 28
⇒ m = 28/ 2 = 14
Using value of m in (i) , we get
14 + n = 40 ⇒ n = 26
from this we get there are fourteen 4-point questions and twenty six 2-point questions.
hope this helped!
Answer:
The volume doubles to 120
Step-by-step explanation:
Volume of Rectangular Prism Formula: V = lwh
Step 1: Find volume of given lengths
V = 3(4)(5) = 60 in²
Step 2: Find volume when we double <em>h</em>
4(2) = 8
V = 3(8)(5) = 120 in²
Step 3: Divide the 2 numbers to find the ratio
120/60 = 2, or double the amount.
