Answer:

x = 6.7

Step-by-step explanation:

We know that 3.5 + x = 10.2, so if we do inverse operations we can find out the value of x.

10.2 - 3.5 = 6.7

we can check our work by substituing it back in the equation for x

6.7 + 3.5 = 10.2

so now we know that x = 6.7. I hope this helps :)

What is the y-intercept for the linear function y-4=2(x-6)​
Kruka [31]

Answer:

<h2>-8</h2>

Step-by-step explanation:

Method 1:

The slope-intercept of an equation of a line:

y=mx+b

m - slope

b - y-intercept

We have the equation of a line in the point-slope form:

y-4=2(x-6)

Convert it the the slope-intercept formula:

y-4=2(x-6)            <em>use the distributive property</em>

y-4=2x-12             <em>add 4 to both sides</em>

y=2x-8\to b=-8

Method 2:

The y-intercept is for x = 0. Put x = 0 to the equation:

y-4=2(0-6)

y-4=2(-6)

y-4=-12           <em>add 4 to both sides</em>

y=-8

Pls help me i’m so stuck
vladimir1956 [14]

Answer:

Step-by-step explanation:

If a point (x, y) is reflected across y = -x, coordinates of the image point will be,

(x, y)→ (-y, -x)

Following this rule,

Vertices of the triangle will be,

(3, 1) → (-1, -3)

(3, -2) → (2, -3)

(6, -3) → (3, -6)

Therefore, image of the given triangle A will be,

(-1, -3), (2, -3) and (3, -6)
