1 answer:
Answer:
She pays $240 for 8 lessons.
Step-by-step explanation:
We need to set up equivalent ratios so we can cross-multiply and solve for x, the amount Angela pays for 8 lessons. Make sure to have both the costs in the numerator, and the number of lessons in the denominator. If you mix it up, this won't work.
Cross-multiply:
120*8 = 4x
Solve for x:
960 = 4x
960/4 = x
<u>x = $240</u>

The value of integration of y=16- from x=-1 to x=1 is 94/3.
Given the equation y=16- and the limit of the integral be x=-1,x=1.
We are required to find the value of integration of y=16- from x=-1 to x=1.
Equation is relationship between two or more variables that are expressed in equal to form.Equation of two variables look like ax+by=c.It may be linear equation, quadratic equation, or many more depending on the power of variable.
Integration is basically opposite of differentiation.
y=16-
Find the integration of 16-.
=16x-
Now find the value of integration from x=-1 to x=1.
=16(1)--16(-1)-
=16(1)-1/3+16-1/3
=32-2/3
=(96-2)/3
=94/3
Hence the value of integration of y=16- from x=-1 to x=1 is 94/3.
