How do you solve this system , y=1/2x-4 and y=-2x+1 by graphing

mart [117]

Answer:

x=2

y=-3

Step-by-step explanation:

we have

$y=\frac{1}{2}x-4$ ----> equation A

$y=-2x+1$ ----> equation B

Solve the system by graphing

Remember that the solution of the system of equations by graphing is the intersection point both lines.

using a graphing tool

The intersection point is (2,-3)

therefore

The solution is

x=2

y=-3

HEy, CAn YOu HElp ? :) Plssss (picture below) solve for #5

alexira [117]

Answer: a=60°, b=25°, c=95°,d=60°, e=25°, f=95°, g=60, h=35°

Step-by-step explanation:

a=60°, Because the angle opposite to it is 60°

b=25°, Because if you take 180°-155°, you get 25°

c=95°, Because if you add angles a and b, you get 85°, then you do 180°-85°=95°

d=60°, Because the angle opposite to it does

f=95°, Because angle c, which is opposite to it equals 95°

g=60°, Because if you add angles e and f, you get 85°, then you take 180°-85=95°

h=35°, Because if you add angles c and d, which is 155°, you take 180°-155=35°

Three brothers have ages that are consecutive odd integers. The difference between the age of the oldest and twice the age of th

Genrish500 [490]

N, N+2, and N + 4 are the ages

(N + 4) - (2N) = (N + 2) -24

4 - N = N - 22

2N = 26

N = 13

The brothers are 13, 15, and 17 years old.

Suppose y varies inversely with x. Write an equation if y=-3 when x=17

vodka [1.7K]

Answer:

y = -51 ÷ x

Step-by-step explanation:

The standard format of a inversely proportional equation goes by the format of y = k ÷ x. The question asks us to write an equation if y = -3 when x = 17 and y varies inversely with x.

So we substitute the values y = -3 and x = 17 in the equation y = k ÷ x

K = constant, we have to work this out

-3 = k ÷ 17

-3 × 17 = k

k = -3 × 17

k = -51

k = -51 So then we put this back into the original y = k ÷ x to find our final equation which is y = -51 ÷ x
