Answer:
y = -5x + -7
Step-by-step explanation:
y = mx + b
y = -5x + b
To find b... 8 = -5*-3 + b
8 = 15 + b
8 - 15 = b
-7 = b
So....y = -5x + -7

Abe has some nickels and some pennies. If the pennies were nickels and the nickels were pennies, he would have 80 cents less than he has now. The difference between the number of nickels and the number of pennies that he has
A) Is 12
B) Is 20
C) Is 24
D) Is 28
E) Cannot be Determined
Answer:
B) Is 20
Step-by-step explanation:
Let X represent the number of pennies.
Let Y represent the number of nickels.
We know that X + 5Y = (Y + 5X) + 80.
4Y = 4X + 80
Y = X + 20
Hence, the difference between the number of pennies and the number of nickels is 20.

fifteen subtracted from the product of a number and -4 is at most 32
Answer:
Step-by-step explanation:
Let's use the variable x to represent the unknown number.
Also, the word, "product", indicates multiplication.
In this problem, the product of a number and -4 would be represented as -4 x
The words, "is at most", would be represented as: <
Then to create the inequality, subtract 15:
-4 x - 15 < 32
Now solve the inequality using inverse operations. NOTE - Be sure to reverse the direction of the inequality symbol when multiplying or dividing by a negative number.
4 x - 15 < 32
-4 x - 15 + 15 < 32 + 15
-4 x < 47
-4 x / -4 > 47/-4
x > -47/4
x > -11.75

If the product of two rational numbers is (-9/16) and one of them is (-4/15) find the other number.
Given:
The product of two numbers is (-9/16).One of the numbers is (-4/15)To find: The other number.
Answer:
Let's assume the unknown number to be 'x'.
(-4/15) × x = (-9/16)
× = (-9/16) ÷ (-4/15)
When we divide a fraction by another fraction, the divisor will be taken in its reciprocal form.
x = (-9/16) × (-15/4)
x = 135/64
Therefore, the other number is 135/64.
Hope it helps. :)

The ratio of money in Terry's bank account to Faye's bank account was 3:5.
Terry then put £220 in his account and Faye withdrew £300 from her account.
They now had the same amount in their accounts.
How much did Terry initially have?
Answer:
They initially had £1250 altogether.
Explanation:
Given : The ratio of money in Terry's bank account to Faye's bank account was 3:7.
Let the money in terry's bank account be 3x and the money in Faye's account be 7x.
if Terry put £220 in his account and Faye withdrew £300 from her account.
Money in Terry's account = 3x+200
Money in Faye's account = 7x -300
They now had the same amount in their accounts.
Now Initially ,
Amount in Terry's account = 3x= 3(125) = £ 375
Amount in Faye's account = 7x =7 (125)= £ 875
Combined amount = £ 375 + £ 875 = £1250
Hence, they initially had £1250 altogether.

The points (6, g) and (5, 5) fall on a line with a slope of 3. What is the value of g?
Answer:
g=8
Step-by-step explanation:
First, let's find the equation of the line.
Using point-slope form, which is y-y1=m(x-x1)
we can substitute the given slope (3) and the point (5,5) into the equation
y-5=3(x-5)
do distributive property
y-5=3x-15
add 5 to both sides
y=3x-10
the equation of the line is y=3x-10
since the point (6,g) will fall on the line, we can put it into the equation to find y
y=3(6)-10
y=18-10
y=8
y, or g=8

What is the quadrilateral?The definition of a quadrilateral is a planar form with four sides, four vertices, and four angles. Concave and convex are the two primary kinds.
If all the sides of the quadrilateral are identical, then the quadrilateral will be a square.
In the square, each angle will be a right angle. And the diagonals of the square intersect at a right angle.
Thus, the measure of the angle ∠GQE will be 90°. Then the correct option is C.

The mean age of 3 women in an office is 30 years old.
The mean age of 7 men in an office is 33 years old.
What is the mean age (nearest year) of all the people in the office?
Answer:
32 years
Step-by-step explanation:
Here, we simply calculate the age of all first
For all men, we have 7(33) = 231
For all women = 3(30) = 90
So we simply have;
(90 + 231)/10 = 32.1
Approximately 32 years
