Answer:u
Step-by-step explanation:
V/4-15=29
Multiply each term by 4
V - 60 = 116
V = 116 + 60
V = 176
Answer:
g(x) = 7x^2
Step-by-step explanation:
Given a function f(x), the function kf(x) is stretched by a factor of k. In this case, if we stretch the function f(x) = x^2 by a factor of seven, the new function is going to be the base function multiplied by 7, as follows:
g(x) = 7x^2

Answers:
- slope = 2
- slope = -3
- slope = 1
- slope = 1/4
- slope = 1/4
None of the five lines are horizontal or vertical
===============================================
Explanation:
Something like f(x) = 2x-5 is the same as y = 2x-5. This is because y = f(x).
Compare y = 2x-5 with y = mx+b. We see that m = 2 is the slope in this case.
The other four questions are handled the same way.
A horizontal line occurs when the slope is 0. Since none of the slopes are zero, none of the lines are horizontal.
A vertical line equation is of the form x = k, where k is any real number. The y variable is not involved. It is not possible to write a vertical line equation in the form y = mx+b because the slope m is undefined. So none of the given five equations are vertical lines.
Side note: something like y = x+6 is the same as y = 1x+6
Answer:
Step-by-step explanation:
take 60 degree as reference angle
using cos rule
cos 60=adjacent/hypotenuse
1/2=80/x(do cross multiplication)
80*2=x
160=x
