Answer:
the cost that used to frame the math certificate is $847.80
Step-by-step explanation:
The computation of the cost that used to frame the math certificate is shown below:
= 27 wide × 20 tall × $1.57 per centimeter
= $847.80
Hence, the cost that used to frame the math certificate is $847.80

Answer: x = 4</h3>
==================================================
Explanation:
Replace f(x) with 0 and solve for x.
f(x) = 3x-12
0 = 3x-12
3x-12 = 0
3x = 12
x = 12/3
x = 4 is a zero, aka root, of the function
---------------
Check:
f(x) = 3x-12
f(4) = 3(4)-12
f(4) = 12-12
f(4) = 0
The answer is confirmed.

Answer:
The last one doesn't satisfy! for example if y=2 and x=1 then 2<0 false.
Step-by-step explanation:
Answer:
y = -2x - 8
Step-by-step explanation:
Slope-intercept form is y = mx + b. Slope is m, and y-intercept is b. To do this, we substitute -2 for m and -8 for b. When we do this, we get y = -2x + -8. We can simplify this to y = -2x - 8.
