Answer:
9
Step-by-step explanation:
two negatives make a positve
Answer:
-9
Step-by-step explanation:
Whenever you are given an expression, first look at it. Since there are two negative signs in the equation, they cancel out, leaving a nine. The opposite value most likely means that the sign is the opposite, so you end up with -9 as the value.

Answer:
50⁰
Step-by-step explanation:
Add 130 plus 50 to get 180.
Answer:
x = 50°
Step-by-step explanation:
In a parallelogram consecutive angles are supplementary, thus
∠ BAC + ∠ ABD = 180°, that is
130° + ∠ ABD = 180° ( subtract 130° from both sides )
∠ ABD = 50°
Since ACDB and FGHE are congruent then corresponding angles are congruent, thus
∠ FEH = ∠ ABD = 50° =x
Sue and Gwen each have large collections of CDs. Sue has twice as many CDs as Gwen. Together the girls have 96 CDs. Which equation could be used to find the number of CDs, x, that Gwen has?
Answer:
3x=96
Step-by-step explanation:
From the information given, you can write the following:
a+x=96 (1)
a=2x (2)
where a is the number of CDs that Sue has and x is the number of CDs that Gwen has.
You can replace 2 in 1 and you would have the following:
2x+x=96
3x=96
From this, you can isolate x to find its value:
x=96/3
x=32
According to this, the equation that could be used to find the number of CDs, x, that Gwen has is: 3x=96.

A rectangle that is 2 inches by 3 inches has been scaled by a factor of 7.
1. What are the side lengths of the scaled copy?
2. Suppose you want to scale the copy back to its original size. What scale factor should
you use?
Answer:
[tex]New\ Lengths = (14,21)[/tex]
[tex]New\ Scale\ Factor = \frac{1}{7}[/tex]
Step-by-step explanation:
Given
Rectangle:
Length = 2 in
Width = 3 in
Scale Factor = 7
Solving (a):
The side lengths of the new scale is calculated as follows;
New Lengths = Old Lengths * Scale Factor
[tex]New\ Lengths = (2,3) * 7[/tex]
[tex]New\ Lengths = (2 * 7,3* 7)[/tex]
[tex]New\ Lengths = (14,21)[/tex]
Solving (b): To go back to the original length
Given that the initial scale factor is 7;
The new scale factor is the reciprocal of the old factor;
Hence;
[tex]New\ Scale\ Factor = \frac{1}{7}[/tex]

Which shows like terms from the expression? 9 + 5 + 7x2 + 3 x2y + 2x2 3 x2y and 2x2 7x2, 3 x2y, and 2x2 9 and 5 2, 3, 5, and 9
Answer:
9 and 5.
Step-by-step explanation:
So we have the expression:
[tex]9+5+7x^2+3x^2y+2x^2[/tex]
In order to combine like terms, the variables must be exactly the same: not one less, not one more.
3x²y and 2x² cannot be combined because the first value has a y.
7x², 3x²y, and 2x² also cannot be combined because the second value has a y.
9 and 5 is the only one that can be combined because they are just integers. They can be added to be 14.
2, 3, 5, and 9 cannot be combined because the 2 and the 3 are tied to the variables as coefficients. They are not constants.
To combine like terms, we can combine numbers with the same power and variables.
We are given the equation: 9 + 5 + 7x^2 + 3x^2y + 2x^2
We can combine 9 and 5 because they are whole numbers by themselves.
We can combine 7x^2 and 2x^2 because they are whole numbers that both have a variable (x) and the same power.
We can't combine anything to 3x^2y because no other number has these features.
Best of Luck!

1. How do you identify the terms in an expression? 2. How do you determine the coefficient of a term if you don’t see a number in the term?
A term is an expression is a set of constants, variables, and exponents, while the coefficient of a term is the numerical value present in the term.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
A term in an expression is a set of constant or numerical values, variables, and exponents. Each term of an expression is differentiated from others by a mathematical operation. For example, in the expression 2x²+6x-5, 2x², 6x, and -5 all three are terms and it is differentiated from others by the '+' and '-' operators.
The coefficient of a term is the numerical value present in the term. Let's understand this with the similar example above.
In term 2x², 2 is the coefficient.
In term 6x, 6 is the coefficient.
Hence, a term is an expression is a set of constants, variables, and exponents, while the coefficient of a term is the numerical value present in the term.

How do i solve this for g(-3)?
Answer: g(-3) is 9 .
Step-by-step explanation:
So there are two functions and the first function says that to get the solution x has to be greater than 4 and -3 which is the input is not greater than 4 so you can't use that function to solve for g(-3).
using the second function , it says that x has to be less or equal to 4. And -3 is indeed less than 4 so you have to use the second function to solve for g(-3)
g(x) = -2x + 3 Input -3 and solve
g(-3) = -2(-3) + 3
g(-3) = 6 + 3
g(-3) = 9

Write the equation of the line fully simplified slope-intercept form.
Answer:
y=-x+2
Step-by-step explanation:
The slope-intercept form is y=mx+b where m is the slope and b is the y-intercept.
From the graph, we can see that the y-intercept is at (0,2) so the equation becomes y=mx+2.
Other points on the graph include (1,1) and (2,0). Plugging (1,1) into the slope-intercept equation, we get 1=(m)1+2. Solving this will give us m=-1.
We can confirm this by plugging m=-1 into the equation along with the point (2,0); 0=(-1*2)+2. It checks out!
So our final equation in slope-intercept form will be y=-x+2
Answer: Think it is y=2x+2
Step-by-step explanation: because whats your y intercept it is on the two. Whats your x intercept it is also on the a 2.
write an equation of the line that passes through the given point P and has the given slope m. P(5,4), m=4
Answer: y = 4x - 16
Step-by-step explanation:
Using the point slope formula to plug in your point and slope, I found
y - 4 = 4 (x - 5)
After simplifying it into an equation of the line I got y = 4x - 16

Haley fills a balloon with water until it becomes a sphere with a diameter of 5 centimeters. Approximately, how much water does the balloon contain? Use 3.14 for pi
Answer:
65.41
Step-by-step explanation:
65.3 cm³ is the amount of water filled in the balloon.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Given that Haley fills a balloon with water until it becomes a sphere with a diameter of 5 centimeters.
We need to find how much water does the balloon contain
It means we need to find the volume of the sphere with diameter 5 centimeters.
Volume is defined as the space occupied within the boundaries of an object in three-dimensional space.
Volume of Sphere=4/3πr³
As diameter is 5
Radius=Diameter/2=5/2=2.5 cm
Volume=4/3×3.14×(2.5)³
=1.33×3.14×15.625
=65.25
=65.3
Hence, 65.3 cm³ is the amount of water filled in the balloon.

A family paid $30600 as a down payment for a home. If this represents %17 of the price of the home, find the price of the home
Answer:
180000
Step-by-step explanation:
30600/17=1800
1800•100=180000
Answer:
$180,000
Step-by-step explanation:
First you have to change 17% into a decimal which would be 0.17 which makes it easier to work with.
If we put this into an equation we know some value of x is the original price of the house and 0.17 (17%) of this unknown x is 30600.
Therefore: x * 0.17 = 30600
We divide 0.17 on both sides to cancel it on the left and get x by itself.
Now x = 30600/0.17
We get x = $180,000
Therefore, the original price of the home was $180,000.
