Answer: Graph D
Step-by-step explanation:
The slope is 2
x goes after the slope in graph functions
The line goes through 3 on the y-axis so that’s where + 3 comes in.
2x + 3
Answer:
- 2
Step-by-step explanation:
3 ( x + 5 ) = 9
x + 5 = 9 / 3
x + 5 = 3
x = 3 - 5
x = - 2
Answer:
Step-by-step explanation:
The pizza shop is offering two pizzas for the same price.
The round one is 12 inches in diameter. To know the size of the round pizza, we will determine its area. It is the same as the area of a circle which is expressed as
Area = πr^2
Radius, r = diameter /2 = 12/2 = 6 inches.
π = 3.14
Area = 3.14 × 6^2 = 3.14 × 36 = 113.04 inches square.
To know the size of the square pizza, we will apply the formula for a square
Area = l^2
Since one side is 10 inches,
The area is 10.5 × 10.5 = 110.25 inches square.
It means that the round pizza is bigger. She should by the round pizza
Answer:
x is 7, y is -1
Step-by-step explanation:
x+7y=0
2x-8y=22 -> divide both sides by -2
x+7y=0
-x+4y=-11
Eliminate one of the equations by adding the equations.
11y=-11
y=-1
Substitue the value of y into te equation
x+7*(-1)=0
x=7
