Answer:
B
Step-by-step explanation:
Remark
The easiest way to do this is to Substitute for y in the top equation.
2x + 4y = 18 Divide by 2
2x/2 + 4y/2 = 18/2
x + 2y = 9
Substitute -3x + 2 in for y in the equation above
x + 2(-3x + 2) = 9
x - 6x + 4 = 9
Combine like terms on the left
-5x + 4 = 9
Subtract 4 from both sides.
-5x + 4-4 = 9- 4
-5x = 5
Divide by -5
-5x/-5 = 5/-5
x = - 1
That makes A and C incorrect.
y = -3x + 2
y = -3(-1) + 2
y = 3 + 2
y = 5
The correct answer should be (-1,5) which is B
Answer:
Your Answer is B.
Step-by-step explanation:
If the number inside the () is positive, it shifts left. If it is negative, It shifts right. The other number is up if positive, down if negative.
Hey there!
This is a little confusing. But it’s 10. If there’s 2 sides with the length of 4 and one with 10, then it’s not a closed triangle. With two sides lengths of 10 and one with 4, the triangle is able to be closed.
I hope this helps!
Answer:
4 cups
Step-by-step explanation:
because if you have 2 cups for a half a quart then add another half which means add 2 more cups 2+2=4 cups
You multiply 5 *12 =60 then you subtract 2 equalling 58
