two negatives cancel out and turn the 24 to a positive number
6×4=24
Solve the system of equations x+y=-8 and -9x-6y=60 by combining the equations
Answer:
x = - 4 y = - 4
Step-by-step explanation:
x+y= - 8
-9x-6y=60
First, solve for x in the first equation:
x+y = - 8 Subtract y from both sides
x + y - y = -8 - y y cancels on the left
x = - 8 - y
Now plug in what you found for x into the 2nd equation and solve for y.
- 9x - 6y = 60
-9(- 8 - y) - 6y = 60 Multiply out
72 + 9y - 6y = 60
72 + 3y = 60 Subtract 72 from both sides
72 - 72 + 3y = 60 - 72 72 cancels on the left
3y = - 12 Divie both sides by 3
3y/3 = -12/3 3 cancels on the left because 3/3 = 1
y = -4
Now plug your answer for y back into the first equation to get x.
x + y = -8
x + (-4) = - 8 Add 4 to each side
x - 4 + 4 = - 8 + 4 4 cancels on the left
x = -4
x = - 4 and y = - 4
Martina purchased a prepaid phone card for $20. Long distance calls cost 21 cents a minute using this card. Martina used her card only once to make a long distance call. If the remaining credit on her card is $11.39, how many minutes did her call last?
if you are multiplying 4 negative fractions is the product positive or negative?
answer: positive
for example: -2 x -2 x -2 x-2
=4 x -2 x -2
=-8 x -2
=positive 16
Answer:
Positive
Step-by-step explanation:
When multiplying, any even number of negatives results in a positive answer. If multiplying an odd number of negatives, the product will be negative.
The volume of dry goods, like apples or peaches, can be measured usings bushels, pecks, and quarts. A bushel contains 4 pecks, and a peck contains 8 quarts. What is the relationship between number of bushels, b, and the number of quarts, q?
Answer:
1 bushel = 32 quarts
Step-by-step explanation:
It is given that,
No. of pecks in a bushel = 4
No of quarts in a peck = 8
We need to find the relationship between number of bushels, b, and the number of quarts, q.
No. of quarts in 4 pecks = 4×8 = 32 quarts
It would mean that there are 32 quarts in 1 bushel.
Hence, 1 bushel = 32 quarts

8 - 2(3х – 1) = x+ 9?
Answer:
x=1/7 or 0.14
Step-by-step explanation:
first you distribute: 8-6x+2=x+9
next combine like terms (8 and 2): -6x+10=x+9
then subtract 1x from both sides: -7x+10=9
then subtract 10 from both sides: -7x=-1
divide both sides by -7: x=1/7 or 0.14

Answer:
b
Step-by-step explanation:
As x → + ∞ , y → + ∞ , as x → - ∞, y → - ∞
This means as x increases to the right, y increases up and as x increases to the left, y is increasing downwards

True or False: If a function crosses an axis at (a,0), this location is known as an x-intercept of the function.
Answer:
True
Step-by-step explanation:
Given
[tex]Location: (a,0)[/tex]
Required
Does the location represent the x intercept?
The general point form of a function is (x,y)
When y = 0;
This represents that the function crosses the y axis.
And whenever the function crosses the y axis, we have the x intercept of the function
Hence, the statement is true

HELP ME PLEASE 20 POINTS
HELP
Answer:
The answer is
[tex]( \frac{3}{2} \: , \frac{5}{2} ) \: \: or \: \: (1.5 \: \: , \: \: 2.5)[/tex]Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
[tex]M = ( \frac{x1 + x2}{2} \: , \: \frac{y1 + y2}{2} )[/tex]where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
C (4,6) and D(-1, -1)
The coordinates of the midpoint is
[tex]M = ( \frac{4 - 1}{2} , \: \frac{6 - 1}{2} )[/tex]We have the final answer as

The sum of two numbers, x and y is 14. Twice the first number x and triple the second number y is 63. Find x and y.
Answer:
x = -21, y = 35.
Step-by-step explanation:
Use the elimination method:
x + y = 14
2x + 3y = 63
Multiply the first equation by -2:
-2x - 2y = -28
Add this to the second equation to eliminate x:
y = 35
So x + 35 = 14
x = 14 - 35
x = -21.

Convert the given fractions into like fractions.
To do so, Take the L.C.M ( Least Common Multiple ) of 3 and 4.
To find out the L.C.M of given numbers,
First of all, find the prime factors of each numbers.
3 = 3 × 1
4 = 2 × 2 × 1
Take out the common prime factor i.e 1
Also take out the other remaining prime factors i.e 2 , 2 and 3
Now, multiply those all prime factors and obtain L.C.M
= 1 × 2 × 2 × 3 = 12
L.C.M of 3 and 4 = 12
[tex] \dashrightarrow{ \sf{ \frac{5 \times 4 + 7 \times 3}{12}}} [/tex]
[tex] \dashrightarrow{ \sf{ \frac{20 + 21}{12}}} [/tex]
Add the numbers : 20 and 21
[tex] \dashrightarrow{ \sf{ \frac{41}{12}}} [/tex]
Convert the improper fraction into mixed fraction
[tex] \dashrightarrow{ \boxed{\sf{3 \frac{5}{12} }}}[/tex]
Remember : While performing the addition or subtraction of unlike fractions, you have to express the given fractions into equivalent fractions of common denominator and add or subtract as we do with like fractions. Thus , obtained fractions should be reduced into lowest terms if there are any common on numerator and denominator. But in case of improper fraction, it needs to be deduced on mixed fraction.
Hope I helped!
