Answer:
x is 12
Step-by-step explanation:
You can find x two different ways.
The first way is to look at the numbers on the left side. You need to find the scale factor used to get from 4 to 6.
4 x 1.5 = 6
Use this for the 8
8 x 1.5 = 12
The other way you can use is look at the number on the top triangle. You need to find the scale factor used to get from 4 to 8.
4 x 2 = 8
Use this for the 6
6 x 2 = 12
Well i think that it would be 8×8-40 and that would come out to a solution of 28
Answer: y = 40x + 750
Step-by-step explanation:
Linear model;
y = mx + c
y is the total cost of buying granite counter tops for a certain number of square foot as well as the cost to install the counter top.
m is the cost of granite counter tops per square foot which is $40 in this case.
x is the number of square feet required.
c is the base pay for the installation of the counter top which is $750
Linear model will therefore look like this;
y = 40x + 750
To test it. Assume you want enough granite tops for 10 square feet. How much would it cost;
= 40 (10) + 750
= $1,150
