Answer:
as below
Step-by-step explanation:
= 
2(4x + 17) = 7(6x)
8x +34 = 42x
34 = 42x-8x
34 = 34x
= x
1 =x :)
Answer:
y = 3x - 9
Step-by-step explanation:
We first need to find the slope (m)
m = 
= 
= 
= 3
y = mx + b
y = 3x + b
(4, 3)
y = 3x + b
3 = 3(4) + b
3 = 12 + b
-12 -12
-9 = b
(1, –6)
y = 3x + b
-6 = 3(1) + b
-6 = 3 + b
-3 -3
-9 = b
y = 3x - 9
To check: (1, –6)
y = 3x - 9
-6 = 3(1) - 9
-6 = 3 - 9
-6 = -6

A. He eats 1/8 a pound of candy each day.
B. It would take him a total of 8 days to eat a pound of candy.
A. Since he ate 10 ounces in 5 days, you divide 10 by 5 to find he ate 2 ounces per day. Since there are 16 ounces in a pound that would be your denominator (bottom of fraction) and 2 would be the numerator (top of your fraction). You will get 2/16 which if you simplify (divide by 2) you get 1/8.
B. Knowing that there are 16 ounces per pound and he ate 1/8 pound ( 2/16 pound or 2 ounces) a day, you can either look at the simplified denominator to get the answer, or, divide 16 by 2 to get your answer.
I hope this helps!

From the given equation, -3x² - x - 3 = 0
where a = -3, b = -1, c = -3

Answer:
Step-by-step explanation:
y = 3 - xy
Let x = 1
y = 3 - (1)y
Expand brackets.
y = 3 - y
Add y to both sides.
2y = 3
Divide both sides by 2.
y = 3/2
