Answer:
y intercept: (0,-13)
x intercept: (13/5, 0)
Step-by-step explanation:
To find the y intercept, x has to equal zero. So, plug it in. The equation becomes y=-13.
Since x is zero, the point becomes (0,-13)
To find the x intercpet, y has to equal zero. So, plug it in. The equation becomes 0=5x-13.
move 13 to the other side
13=5x
divide by 5
13/5=x
Since y is zero, the point becomes (13/5,0)
hope this helps!
Answer:
For part 1- y=50x+75 For part 2- y=325
Step-by-step explanation:
the cost is increasing 50 for every hour
there is a flat rate of 75 to answer a house call
y=50x+75
y=50(5)+75
y=250+75
y=325
Answer:
7pi/2
Step-by-step explanation:
Given the expression cosec x = -1
I'm trigonometry csecx = 1/sinx
The equation becomes
1/sin(x) = -1
Sinx = -1
x = arcsin(-1)
x = -90°
x is negative in the third and 4th interval
Third interval;
x = 180+90
x = 270°
x = 3pi/2
Since the angle should be within 3pi < x < 4pi
Add 2pi to the angle
x = 2pi+ 3pi/2
x = 7pi/2
Hence the required angle is 7pi/2
First solve to your equation by step by step.
1/5(2x-10)+4x=-3(1/5x+4)
= x=-2
Answer is x=-2

I think the expression for that is 13 • h • 3 because he gets $13 per hour and we don't know how many hours he worked so we would just put a variable and then he worked three times as many hours so multiply by 3. I might be wrong but hopefully it helps
