The answer is -1. You multiply the 1/4 with the 5x and equal it to 3 multiplied by 5 and have gotten 15x, then multiply the 3 with the 2, as apart of the parentheses. Lasty you just leave the -9 on the side and solve the equation.
-7x-2y=-13
x= 2y+11 make x or why the subject and substitute it into the first equation.
-7(2y+11)-2y=-13
-14y-77-2y=-13
-16y=64
y=-4
x=-2×-4+11
x=3
Answer:
Slope of line 1 = 3
Slope of line 2 = 3
Slope of line 3 = -1/3
Line 1 and 2 are parallel
Line 1 and 3 are perpendicular
Line 2 and 3 are perpendicular
Step-by-step explanation:
Find the slope of each line by using this equation:

lines are parallel if they have the same slope and line are perpendicular in they have opposite reciprocal slopes. (-1/3 is the opposite reciprocal of 3).
Hope this helps!
Answer:
HCDG
Step-by-step explanation:
Answer:
The probabilty that the arrow will land on a section labeled with a number greater than 3 would be 3/5
Step-by-step explanation:
Formula
P = (the number of possible outcomes) ÷ ( the number of total result)
The total number of the result = 8
The spinner shown is divided into 8 equal sections. What is the probability that the arrow will land on a section labeled with a number greater than 3
Therefore the answer is 3/5
If the answer is wrong it must be a different question
