1. To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y. ...
2. To find the x-intercept, set y = 0 \displaystyle y=0 y=0.
3. To find the y-intercept, set x = 0 \displaystyle x=0 x=0.
Answer:
0.25
Step-by-step explanation:
3/12 = 1/4
1÷4= 0.25
A = 5
4a + b = 6
4(5) + b = 6
20 + b = 6
b = 6 - 20
b = - 14 <=== u can prove that b = -14
A room area
Lenght × Width = 16 × 12
= 192 square feet
1 square yard = 9 square feet
so 1 square feet = 1/9 square yard
192 square feet = 192 × 1/9 square yard
= 64/3 square yard
Total cost
$30 × 64/3 = $640
