Answer:
-8/5 = x
Step-by-step explanation:
-3(x+4) = 7x + 4
Distribute
-3x-12 = 7x+4
Add 3x to each side
-3x-12+3x = 7x+4+3x
-12 = 10x+4
Subtract 4 from each side
-12-4 = 10x+4-4
-16 = 10x
Divide by 10
-16/10 = 10x/10
-8/5 = x
The question is asking for the highest common factor (HCF)
1220 =
x 5 x 61
549 =
x 61
HCF = 61
Ans: 61
The answer is rhombus because first of all it is the only one who has no right triangle. Its also did not say that it has parallel sides. Plus it has 4 sides which means its a rhombus
Answer:
y = 6x-4
Step-by-step explanation:
3x - 1/2 y =2
We need to solve for y to get the equation in slope intercept form
Subtract 3x from each side
3x-3x - 1/2 y =-3x+2
-1/2 y = -3x+2
Multiply each side by -2
-2*-1/2 y = -2*(-3x+2)
y = -2*(-3x+2)
Distribute
y = 6x-4
The slope is 6 and the y intercept (where it crosses the y axis) is -4
