3x - 5 = x - 7
-x -x
2x - 5 = - 7
+5 +5
2x = -2
Divide 2 on both sides. The answer is x = -1
Answer:
A. y=x+4
Step-by-step explanation:
I used Desmos to graph all the information and the black line (which is A) goes through all the points. See picture
Your answer should be 148! (Keep in mind that slope = change in y/ change in x.) Hope I helped!
Answer:
y = 2
Step-by-step explanation:
So we need to find the slope first.
m = y_2 - y_1/x_2 - x_1
Substitute
m = 2 - (2)/8 - (-3)
Simplify now.
Multiply -1 by 2
m = 2 - 2/(8 - (-3)
2 from 2
m = 0/8 - (-3)
Now we need to simplify the denominator.
To do so lets multiply -1 by -3
m = 0/8 + 3
m = 0/11
m = 0
Now we have the slope of 0 and the given point of (-3, 2)
So y - (2) = 0 * (x - (-3)) (Formula > y - y_1 = m(x - x_1) this comes from the original slope equation]
Simplify further
y - 2 = 0 * (x + 3)
Now we solve for y
Multiply 0 by x + 3
y - 2 = 0
Add 2 to both sides
y = 2
Answer:
8/25
Step-by-step explanation:
The total amount of tickets is 25 so divide 10 from 25 to figure out what you multiply by to get 25
--> 25/10 = 2.5
now multiply 2.5 x 3 to have a numerator which would be your probability of winners out of 25 tickets
--> 2.5 x 3 = 7.5 (round to the nearest whole number)
7.5 rounded to the nearest whole number --> 8
so you get 8 out of 25 = 8/25
