The answer is the third one
Answer: 80 sq. ft
Step-by-step explanation:
Company A’s charges can be represented by the equation: 10m + 250
Company B’s charges can be represented by the equation: 12m + 90
To find when the square feet got which they have the same amount, I will set them equal to each other and solve for it.
10m+250=12m+90
-10m -10m
250=2m+90
-90 -90
160=2m divide both side by 2
80=m
For 80 square feet, both companies charge the same amount.
Answer:
1. 5b^2-b-2 (so option 3)
2. 4x-1 (so option 2)
Step-by-step explanation:
For the first one you need to just simplify the expression
For the second one you need to combine like terms
Answer:x=-3
Step-by-step explanation:
Given:
The table of values.
To find:
The slope and y-intercept for this line.
Solution:
From the given table, we have three (-4,6), (0,3), (4,0).
We need to find the slope and y-intercept for this line.
Consider any two points from the given points.
Consider the line passes through the points (0,3) and (4,0). So, the slope of the line is:
The line passes through the point (0,3). Here the x-coordinate is 0. So, the y-intercept is 3.
Therefore, the slope of the line is and the y-intercept of the line is 3.
