Answer: b/9 + 3 = 7

Step-by-step explanation:

Quotient of 'a number' and 9 is b/9

3 more than that is b/9 + 3

this equals 7, so b/9 + 3 = 7.

Answer:

\frac{b}{9} + 3 = 7

Step-by-step explanation:

The phrase "x more than y" indicates addition; x + y.

"Three more than the quotient of a number and 9" would mean that we would have to add 3 to the quotient of the unknown number and 9.

The "quotient of a number and 9" can be written as  \frac{b}{9} .

Finally, we would add "= 7" to the end of the equation to represent "equals 7".


"Three more than the quotient of a number and 9 equals 7" is \frac{b}{9} + 3 = 7.

Hope this helps.

Find the slope of the line that passes through (-24, 90) and (-23, 52).
Ostrovityanka [42]

Answer:

-38

Step-by-step explanation:

The slope is rise over run.  You need to find out how far one point is from the other.  To do this, use the equation for slope.

m=\frac{y_{2}-y_{1}  }{x_{2}- x_{1} }

Plug in the points given into the equation and solve for slope (m).

m=\frac{y_{2}-y_{1}  }{x_{2}- x_{1} }\\m=\frac{90-52  }{-24-(-23) }\\m=\frac{90-52  }{-24+23 }\\m=\frac{38}{-1} \\m=-38

The slope of the line is -38.

A rectangle has perimeter 20 m . Express the area of the rectangle as a function of the length of ones its side.
kondor19780726 [428]

Answer:

A = 10W - W²

Step-by-step explanation:

Perimeter of a rectangle = 2(L+W)

Area of a rectangle =LW

L is the length

W is the width

Given

Perimeter = 20m

20 = 2 (L+W)

10 = L+W

L = 10 - W ....2

Substitute equation 2 into the formula for calculating the area

Recall that A = LW

A = (10-W)W

A = 10W - W²

Hence the area of the rectangle as a function of the length of ones its side is expressed as A = 10W - W²

The slope is 1, so m = 1. 
The given point is (x,y) = (1,5) which means x = 1 and y = 5 pair up together.

Plug the three pieces of info (m = 1, x = 1, y = 5) into the y = mx+b equation. Then solve for b

y = mx+b
y = 1*x + b ... replaced m with 1
5 = 1*1 + b .... replaced x with 1, replaced y with 5
5 = 1+b
1+b = 5
b+1 = 5
b+1-1 = 5-1
b = 4

Since m = 1 and b = 4, we know that y = mx+b turns into y = 1x+4 which simplifies to y = x+4

Answer: y = x+4
