Answer:
7.8
Step-by-step explanation:
subtract 85 - 77.2
Answer:
B. y - 1 = -4[x - (-3)]
Step-by-step explanation:
Given:
Slope = -4
Point = (-3, 1)
Required:
Point-slope form of the line
Solution:
Equation of a line in Point-slope form is given as y - b = m(x - a).
Where,
a = -3
b = 1
m = -4
Plug in the values
y - 1 = -4[x - (-3)]
Answer:
Equation 2 of system divided by 2 on both sides then we get second equation of system 2.
Step-by-step explanation:
We are given two equations


We are given a proof which shows an equivalent system of equations created from another system of equations
We have to fill the correct reason in the blank space
Statement:

Reason: Given
Statement :

Reason : equation 2 of system I divided by 2 on both sides then we get second equation of system 2.
When we divide by 2 then the solution does not change and x and y - intercepts are not change.So, the two systems are equivalent.
I don't know if this is right
I am pretty sure that B is the answer
