Answer:
a)7x-3x
b)4+28y
Step-by-step explanation:
first one follow bidmas
2nd one just do 4 times 1 =4 and 7y times 4 equals 28y
Answer: m = -4 / 2 = -2 / 1 = -2
Slope (m) = -2
Step-by-step explanation:
Answer:
Option B
Step-by-step explanation:
Slope of the line is calculated by the formula:

We have the points ( -2 , 4) and (3 , -5) so plug in the values in the formula:

so the slope(m) equals -9/5
X= -14/3 that's the answer there bud i need to make this 20 caracters longs so yeah x=-14/3
3:8 can also be written as 3/8
12:32 can also be written as 12/32

So thus 3:8 is equivalent to 12:32
