Answer:

5,8

Step-by-step explanation:

<em>y</em><em>=</em><em>4</em><em>x</em><em>-</em><em>2</em><em>-</em><em>-</em><em>-</em><em>-</em><em>-</em><em>(</em><em>i</em><em>)</em>

<em>y</em><em>=</em><em>x</em><em>+</em><em>1</em><em>3</em><em>-</em><em>-</em><em>-</em><em>-</em><em>(</em><em>i</em><em>i</em><em>)</em>

<em>E</em><em>q</em><em>u</em><em>a</em><em>t</em><em>i</em><em>n</em><em>g</em><em> </em><em>e</em><em>q</em><em>u</em><em>a</em><em>t</em><em>i</em><em>o</em><em>n</em><em> </em><em>i</em><em> </em><em>a</em><em>n</em><em>d</em><em> </em><em>i</em><em>i</em><em> </em><em>w</em><em>e</em><em> </em><em>g</em><em>e</em><em>t</em><em>,</em>

4x - 2 = x + 13

4x - x = 13  + 2

3x = 15

x = 3

substitutin \: the \: value \: of \: x \: in \: equation \: (i)

y = 4x - 2

y = 4 \times 5 - 2

y = 20 - 2

y = 18

The photo is kinda blurry but I need help fast
enyata [817]

To find the rate of change find the difference in the Y values for every X value.

From X 1 to X 3 the Y value changes by -10

-10 / 2 = -5.

The rate of change is -5.

The initial value is when X = 0

When X is 1, the Y value is 20, using the rate of change of -5, this means when X is 0, the Y value would be 25.

The answer would be, the initial value is 25, rate of change is -5

What is the name of the triangle in which none of the sides have the same length?
VikaD [51]
When a triangle has two congruent sides it is called an isosceles triangle. The angles opposite to the two sides of the same length are congruent. A triangle without any congruent sides or angles is called a scalene triangle. When two triangles are congruent it means that they have the same size and shape.                                                                                                                                  please make me brainliest
