Answer:
x= -4
graph with a closed circle over the intended number
Step-by-step explanation:
These inequalities are basically the same steps as equation.
Step 1: subtract 7 from the 19 on the other side of the equation, this equals 12
Step 2: divide -3 by 12 this equals -4
For these equations, you have to inverse the operations (i.e + to -). that is why you subtract and divide. (-3x) is the same as multiplication. The coefficient and variable are being multiplied.
In equations, usually 'y' as it a product, whereas 'x' is part of the function
Answer: B) h(2) = 16
<u>Step-by-step explanation:</u>
Domain: -3 ≤ x ≤ 11
Range: 1 ≤ y ≤ 25
h(8) = 19
A) x = 8, y = 21
It is given that h(8) = 19. A function cannot have two y-values for one x-value.
B) x = 2, y = 16
The x-value is in the Domain and the y-value is in the Range.
C) x = 13, y = 18
The x-value is not in the Domain <em>(x is between -3 and 11).</em>
D) x = -2, y = -1
The y-value is not in the Range <em>(y is between +1 and 25).</em>
Answer:
$393.75
Step-by-step explanation:
cost of special background paint = $1.25 per square foot
Area of background = area of triangle + area of rectangle
= 1/2 ( b*h) + L * B
= 1/2 ( 5 * 6 ) + 5 * 4 = 15 + 20 = 35 yd^2
Given that 1 yd^2 = 9 ft^2
35 yd^2 = ( 9 * 35 ) ft^2
Hence area of background = 315 ft^2
Cost = 315 * 1.25 = $393.75
