Answer:

y = 2x - 4

Step-by-step explanation:

What equation is being graphed?

A. y+5= -3/2(x-4)
B. y-5= -2/3(x+4)
C. y-5= -3/2(x+4)
D. y-4= -3/2(x+5)

Answers

Answer:

D. y-4= -3/2(x+5)

Step-by-step explanation:

Firstly, taking two valid ordered pairs from the graph:

(-2,4) and (2,-2)

Using Delta y over Delta x, we are able to obtain m as -3/2

Next,

The following is the point-slope formula:

y-y₁=m(x-x₁)

Based on the graph, (4,-5) can be spotted as a definite ordered pair

Therefore, y-4= -3/2(x+5) fits the graph best and has the appropriate m value.

system of equations

Answers

Answer:1:(2,7)

2:i or (1,-3)

3:is c or (-15,-25)

Step-by-step explanation:like if this helped mark me brainlest please

Answer:

(2,7)

(1,-3)

(-15,-25)

Step-by-step explanation:

Because both equations are equal to the same thing (y) we can just set them equal to each other and solve for x

4x-1=2x+3

solve for x

4x=2x+4

2x=4

x=2

We know that x=2 and can plug this value in for x into any of the beginning equations

4(2)-1=y

7=y

The answer is (2,7)

2.) We can do the exact same process as question one

x-4= -3x

-4= -4x

x=1

plug this x value in into any of the starting equations

1-4=y

-3=y

The answer is (1,-3)

3.) Same deal as the other two

x-10=2x+5

-x=15

x= -15

Plug this value in for x into any beginning equation

2(-15)+5

-30+5

y= -25

(-15,-25)

the sum of the measures of two exterior angles of a triangle is 272. what is the measure of the third exterior angles

Answers

Answer.

Step-by-step explanation:

Given = sum of two exterior angle of a triangle is 272 .

rule of triangle is that each and every angle which are outside a triangle is 360.

so, 272 + x = 360

x = 360 - 272

x = 88

help please!! solve for x

Answers

im kinda bad at explaining, but basically what you have to do is find the angle to the right of the 50° angle. since theres an equilateral triangle, 180-50-90= 40. since the triangle x is in has 2 equal sides, 2 of the angles are 40. so, 180-40-40=100. sorry if that's off

Answer:

a = 8, b = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

Given the exponential function

f(x) = a[tex]b^{x}[/tex]

To find a and b use the given coordinate points on the graph

Using (0, 8 ), then

8 = a[tex]b^{0}[/tex] [ [tex]b^{0}[/tex] = 1 ] , then

a = 8

f(x) = 8[tex]b^{x}[/tex]

Using (2, 18 ) , then

18 = 8b² ( divide both sides by 8 )

[tex]\frac{18}{8}[/tex] = b² , that is

b² = [tex]\frac{9}{4}[/tex] ( take the square root of both sides )

b = [tex]\sqrt{\frac{9}{4} }[/tex] = [tex]\frac{3}{2}[/tex]

Thus

f(x) = 8[tex](\frac{3}{2}) ^{x}[/tex]

Answer:

Dark blue on the left.

Step-by-step explanation:

The simplest way is to plug in the values. However, you can immediately get rid of yellow and red because the y intercept is -2.

We have two equations left so the best is plug in the points (0,-2).

For the first equation, 4x^2-2, plug in x which is 0.

4(0)^2-2. Simplify to get 0-2. y=-2.

Dark blue is the answer.
