Answer:
70
Step-by-step explanation:
30 + 40 = 70
Y - 2x = 2 ....put in y = mx + b form
y = 2x + 2
In y = mx + b form, the slope will be in the m position and the y intercept will be in the b position.
y = 2x + 2.....so we have a slope(m) of 2, and a y int (b) = (0,2)
the x intercept can be found by subbing in 0 for y and solving for x
0 = 2x + 2
-2x = 2
x = -2/2
x = -1......so the x int is (-1,0)
go ahead and plot ur intercepts....(-1,0) and (0,2)......and since ur slope is 2, start at (-1,0) and go up 2 spaces and to the right 1 space, then up 2 and to the right 1........thats ur line and it crosses the y axis at (0,2)
Answer:
Step-by-step explanation:
m = 4
![y -y_{1}=m(x -x_{1})\\\\y - 4 = 4(x -[-1])\\\\y - 4 = 4(x + 1)\\\\y -5= 4x + 4\\\\y = 4x + 4 + 5\\y = 4x + 9](https://tex.z-dn.net/?f=y%20-y_%7B1%7D%3Dm%28x%20-x_%7B1%7D%29%5C%5C%5C%5Cy%20-%204%20%3D%204%28x%20-%5B-1%5D%29%5C%5C%5C%5Cy%20-%204%20%3D%204%28x%20%2B%201%29%5C%5C%5C%5Cy%20-5%3D%204x%20%2B%204%5C%5C%5C%5Cy%20%3D%204x%20%2B%204%20%2B%205%5C%5Cy%20%3D%204x%20%2B%209)
Answer:
Question 1: 4/5 or %80
Question 2: 7/10 or %70
Step-by-step explanation:
<u>Step 1: Find the total amount of marbles</u>
5 + 2 + 3
<em>10</em>
<em />
<u>Step 2: Find the probability of not drawing a black marble</u>
Add the total amount of marbles that are not black
5 + 3
<em>8</em>
<em />
Now find the probability:
8/10
4/5 or %80
Answer: 4/5 or %80
<u>Step 3: Find the probability of not drawing a red marble</u>
Add the total amount of marbles that are not red
5 + 2
<em>7</em>
<em />
Now find the probability:
7/10 or %70
Answer: 7/10 or %70
