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
Answer:
Step-by-step explanation:
9x - 4 + 5x + 16 = 180
14x + 12 = 180
14x = 168
x = 12
Answer:
4
Step-by-step explanation:
it's just another way of saying find the slope
Answer:
Below.
Step-by-step explanation:
In factor form this is:
f(x) = a(x + 3)(x + 1)(x - 2) where a is a number to be found.
As it passes through (3, 6) we have:
6 = a(3 + 3)(3 + 1)(3 - 2)
24a = 6
a = 1/4.
So f(x) = 1/4(x + 3)(x + 1)(x - 2)
In general form this is:
f(x) = 1/4 x^3 + 1/2 x^2 - 5/4 x - 3/2
Answer:
X = 8
Step-by-step explanation:
Since the shape is a parallelogram the opposite sides are equal
The equation is:
Solve:
- 6 + 10 = 2x -10 + 10
- 16 = 2x
- 2x = 16
- Divide by 2 on both sides
- <u>x = 8</u>
Check:
- 2(8) - 10 = 6
- 16 - 10 = 6
- 6 = 6
- CD = BE
- 6 = 6
