Answer:
y=2x+6
Step-by-step explanation:
The slope is 2x and the y-intercept is 6. It is shown how to graph it in the attachment.

2 lb, and her books (b) weigh 3 lb each. How
many books can she carry in her backpack?
Answer:
nothing
Step-by-step explanation:
16-9=
10-___=_____
Also it's a made up question
PEMDAS = Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
First, subtract the numbers in the parentheses, then multiply by 11.
(12 - 9) = (3)
3 x 11 = 33
19 + 11 - 12^2 ÷ 3(33) - 7
Now, just multiply 33 by 3, and then square 12 (12 x 12).
19 + 11 - 144 ÷ 99 - 7
Now, you can divide 144 by 99, this is an infinite number, so..
144 ÷ 99 = 1.455
19 + 11 - 1.455 - 7
Finally add, then subtract.
30 - 1.455 - 7
28.545 - 7
The final answer is 21.545.
34 ft
The perimeter of the rectangle is:
P = 136ft
For a rectangle of length L and width W the perimeter is:
P = 2*(L + W)
And for a square of side length S, the perimeter is:
P' = 4*L
The length of the rectangle is:
L = 34ft + x
The width is W = x
For the square we have the side length S = x
Here we know that the perimeter of the rectangle is twice the perimeter of the square, then:
2*(W + L) = 2*(4*S)
Replacing these variables in terms of x, we get.
2*(x + 34ft + x) = 2*(4*x)
4x + 68ft = 8x
68ft = 8x - 4x = 4x
68ft/4 = x = 17ft
Then the perimeter of the rectangle is:
P = 2*(34ft + 17ft + 17ft) = 136ft

Answer:
y = 3x + 7
(Not sure what the question was so, I just put it in slope intercept form)
Step-by-step explanation:
Let x be Steve's age.
Steve = x
Steve's Mom = y
Now let's create an equation:
y - 7 = 3x
y = 3x + 7
(Not sure what the question was so, I just put it in slope intercept form)
Please let me know if I misunderstood the question that way I can help you! <3
Answer:
Steve's mom is 65.
Step-by-step explanation:
Let s = Steve's age.
s + (3s - 7) = 65
4s - 7 = 65
4s = 72
s = 18
Check:
Steve is 18
His mom is (3 * 18) - 7 = 54 - 7 = 47
14 + 47 = 65
Yep.
18 + 47 = 65
