Answer:
± 5
Step-by-step explanation:
2x/-5 = -10/x
2x^2 = 50
x^2 = 25
x = ± 5
Dorothy can type 120 words per minute. Which can also be represented by
120 x 1 (minute)= 120
If you want to know how many words it takes her for 1.75 minutes, simply multiply 120 by 1.75.
120 x 1.75 (minutes)=210
Answer: 210 words
Given, the equation that represents the height of an object:

First, we will find the velocity of the object which is the first derivative of the height using the method of the limits

We will find the value of the function y(t) when t = 3, and when t = 3+h

Substitute y(3+h) and y(3) into the expression of the limit

Where a = 0
d) compute the instantaneous velocity at t = 3

So, the answer will be:
Bagels = x
sesame bagels = x/3 = 72
x/3=72
x=72x3
x=216
Answer:
y=3x +25
Step-by-step explanation:
First calculate the slope:
m = (y1 - y2)/(x1-x2)
m = (49 - 13)/(8-(-4))
m= 36/12 = 3
so we have
y = 3x + b
subtitute a point:
49=3(8) + b
b=25
the equation is y=3x +25
