Answer:

4.6 = X

Step-by-step explanation:

3(x-5)+4x=2x+8

3x-15+4x=2x+8

*3x+4x=7x*

-15+7x=2x+8

+15             +15

7x=2x+23

-2x   -2x

5x=23

/5    /5

x=4.6

Slope intercept! Please help! Will mark brainliest.
avanturin [10]

3) y = -\frac{1}{2}x + 3

Slope-intercept form is y = mx + b when m is the slope and b is the y-intercept

b = 2 (line hits y-axis at 2)

m = \frac{rise}{run} or\frac{change.in.y}{change.in.x} so \frac{1}{2} and the line is negative, so -\frac{1}{2}

Write our equation by putting the parts together, and we get:

y = -\frac{1}{2}x + 3

4) y =  -\frac{2}{3}x - 1.67

Point slope form is y - y1 = m (x - x1) when y1 is the y coordinate of the point, m is the slope, and x1 is the x coordinate of the point

y - y1 = m (x - x1)

Finding the slope (same as above) results in -\frac{2}{3}
