Since AB and BC are two parts of AC, AC = AB + BC
let's plug the expressions from the question into our equation above.
19 = 3x + 1 + 2x - 7
Combine like terms
19 = 5x - 6
Add 6 to both sides.
25 = 5x
Divide both sides by 5
5 = x
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
<u>Answer</u>:
A. y = 
+ 3
<u>Explanation</u>:
slope: 
: 
: 
equation: y - y1 = m( x - x1 )
y - 1 = ( x - 3 )
y = + 3
23.) x=2
24.)same
25.)x=3
26.)x=2
27.)x=3
28.)x= -35/11
Answer:
inverse i believe, because the numbers are switched around on the right side of the equal sign.
