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
Rewrite the following equation in slope intercept form Y+10= 1/4 (x+8)
Answer:
y=1/4x-8

m∠XWY is twice ∠XWZ. Explain whether JJJG WZ must be the angle bisector of ∠XWZ.
The measure of the angle ∠XWZ will be half of the measure of the angle ∠XWY.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.
The measure of the angle ∠XWY is twice the measure of the angle ∠XWZ.
∠XWY = 2 ∠XWZ
Simplify the equation, then we have
∠XWZ = ∠XWY / 2
Then the measure of the angle ∠XWZ will be half of the measure of the angle ∠XWY.

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.

What is the greatest amount of money that rounds to $108.60 when rounded to the nearest dime? What is the least amount of money that rounds to $108.60? Explain your answers.
Answer:
$108.59Step-by-step explanation:
The dime which is worth 0.10 U.S. dollar, is a ten-cent coin, one-tenth of a United States dollar
the value is 0.1
Now in rounding up of numbers the dime is located one decimal place away i.e 0.5 in the number given in the problem statement
to round up to the nearest dime we have to consider the next number to the dime if this number is greater than 5 we will round up if it is less than five we can not perform any rounding up operation
hence the greatest amount of money is
since the number next to 5 is 9 and 9 is greater than 5 we will round up from 5 to 6
This makes 108.59 the greatest amount of money that rounds to $108.60

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
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
