Step by step: -2x + 3= 13
-3 = -3
-2x = 10 divide -2 on each side and get -5, so x=-5, plug that in 2x would be 2( -5) would be -10
ANSWER: -10

A red die is tossed and then a green die is tossed. What is the probability that red die shows a number larger than three and th
makkiz [27]
If you roll two fair dice, a green one and a red one?
A= are the outcomes on the dice independent?
B= Find P(1 on green die and 2 on red die)
C= Find P(2 on green die and 1 on red die)
D= Find P(1 on green die and 2 on red die) or (2 on green die and 1 on red die)

A= yes
B= p(1)*(p2)=1/6*1/6=1/36
C= p(2)*(p1)=1/36
D= 1/36=1/18 I hope it helps !

Write the equation of the line with x-intercept -2 and y-intercept -1 in slope-intercept form
eduard

The x-intercept of -2 gives us an idea that point (-2,0) if found along the line. The y-intercept of -1, tells us that point (0,-1), this also tells us that b = -1.

Now that we have two points, we can solve for slope m

\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ \text{Given two points} \\ (-2,0)\rightarrow(x_1,y_1) \\ (0,-1)\rightarrow(x_2,y_2) \\  \\ \text{Substitute} \\ m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{-1-0}{0-(-2)} \\ m=-\frac{1}{2} \end{gathered}

Now that we have both m and b. Substitute these values to the slope intercept form

\begin{gathered} \text{Slope intercept form is} \\ y=mx+b \\ \text{where} \\ m\text{ is the slope} \\ b\text{ is the y-intercept} \\  \\ \text{Substitute the values from before and we get} \\ y=-\frac{1}{2}x-1 \end{gathered}
