The answer is 18 dollars. If you subtract the $7 he earned, not originally part of his allowance, you get 9. Multiply by 2 because he spent half on the movies and you get 18.
Answer:
12.8
Step-by-step explanation:
Because of your multiplication and dividing.
Answer:64pi
Step-by-step explanation:
Circumference(c)=16pi
Circumference(c)=2 x pi x radius(r)
Substituting we get
16pi=2 x pi x r
Divide both sides by 2pi
16pi/2pi=(2xpixr)/2pi
8=r
Radius(r)=8cm
Area(a)=pi x r^2
a=pi x 8^2
a=64pi
Therefore area of the circle=64pi
Answer:
3x+1 and x+5 are the factors
Step-by-step explanation:
Here's the slide-and-divide method to find the factors:
![3x^2+16x+5](https://tex.z-dn.net/?f=3x%5E2%2B16x%2B5)
![\frac{3x^2}{3}+16x+5(3)](https://tex.z-dn.net/?f=%5Cfrac%7B3x%5E2%7D%7B3%7D%2B16x%2B5%283%29)
![x^2+16x+15](https://tex.z-dn.net/?f=x%5E2%2B16x%2B15)
![(x+1)(x+15)](https://tex.z-dn.net/?f=%28x%2B1%29%28x%2B15%29)
![(3*x+1)(x+\frac{15}{3})](https://tex.z-dn.net/?f=%283%2Ax%2B1%29%28x%2B%5Cfrac%7B15%7D%7B3%7D%29)
![(3x+1)(x+5)](https://tex.z-dn.net/?f=%283x%2B1%29%28x%2B5%29)
Answer:
Slope: ![\frac{4}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B1%7D)
Y - intercept: -1
Step-by-step explanation:
We can see from the graph that the slope is
.
We can also identify the y - intercept as -1.
Therefore, the linear equation would be y =
x -1
Hope this helps:) Goodluck!
