Solve for r: 3r+2-r=-4
Answer:
r = -3
Step-by-step explanation:
3r + 2 - r = -4
2r + 2 = -4
2r = -6
r = -3
Answer:
r = -3
Step-by-step explanation:
3r + 2 - r = -4 (Given)
2r + 2 = -4 (Simplify)
2r + 2 - 2 = -4 - 2 (Subtract 2 on both sides)
2r = -6 (Simplify)
2r/2 = -6/2 (Divide 2 on both sides)
r = -3 (Simplify)

If you check the first one we can verify that WX and ZY are perpendicular as shown with the 90 degree mark then we can see that WX is parallel with AB.
Simplify show step by step 30 POINTS!
What you want to do at the beginning is to "Keep-Change-Flip" the fractions. You're going to keep the first fraction the same, change the divide sign to a multiply sign, and flip the second fraction.
Next, you'll have to factor, and then you can cancel out common components.

Supplement= 180°- 13°
167° Answer
Answer:
167°
Step-by-step explanation:
Supplementary angles, by definition, when combined will give a total angle measurement of 180°.
One of the given angle measurements is 13°. Subtract 13 from the total, 180:
180 - 13 = 167°
167° is the supplement angle.

find the distance between pooler and savannah if there are 2 cm apart on a map with a scale of 1 cm 4.5 miles
Answer:
9 miles
Step-by-step explanation:
I have to ask here too: are you sure you have this description right ? because cm and miles are usually not used in combination.
but fine.
1 cm <-> 4.5 miles
2 cm <-> ? miles
remember questions like "if 1 apple costs $1.10, how much are 2 apples or 5 or 10 apples ?"
you remember what you had to do ?
pretty common sense : you multiplied the price by the same number that you multiplied the unit count number with. so, in my example, by 2, by 5 and by 10. and you got $2.20, $5.50 and $11.00 as prices.
so, what do you think we need to do to calculate the miles that are residents by 2 cm on the map ?
right ! we need to multiply by 2 - because 2×1 = 2.
so, 4.5 × 2 = 9 miles
yes, if 1 cm on the map stands for 4.5 actual miles, then 2 cm stand for 2×4.5 = 9 actual miles.

Enter an ordered pair below so that the point hits the
bullseye.
Press "Submit" to check the location of your point.
. (9,3)
Submit
• (-1, -8)
An ordered pair is simply the x-coordinate and the y-coordinate of a point.
The ordered pair of the bullseye is (4,-2.5)
From the given image (see attachment), we have:
[tex](x_1,y_1) = (9,3)[/tex]
[tex](x_2,y_2) = (-1,-8)[/tex]
The bullseye is at the midpoint of these two points.
So, the ordered pair of the bullseye is calculated using the following midpoint formula.
[tex](x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
So, we have:
[tex](x,y) = (\frac{9-1}{2},\frac{3-8}{2})[/tex]
[tex](x,y) = (\frac{8}{2},\frac{-5}{2})[/tex]
[tex](x,y) = (4,-2.5)[/tex]
Hence, the ordered pair of the bullseye is (4,-2.5)

In the figure, x= ?, y= ?, and z= ?
Answer:
x = 95
y = 147
z = 128
Step-by-step explanation:
x can be found by using the exterior angle triangle theorem, where, when you add the two opposite angles, it equals the measure of the exterior angle. In this case, 50 + 45 = 95.
The same theorem can be used to solve for y. 95 + 52 = 147
We see that angle z is composed of a linear pair, and we have one of the angle values, so just do 180 - 52 and you get 128.

Answer:
0= x
Step-by-step explanation:
8= 8 + 4x +5x
Combine like terms
8 = 8+9x
Subtract 8 from each side
8-8 =8+9x-8
0 = 9x
Divide by 9
0/9 = 9x/9

Step-by-step explanation:
Simplify the following expression and show your work in details please .
Answer:
[tex]4m + 5 - 3m \\ = 4m - 3m + 5 \\ = 1m + 5 \\ = (m + 5)[/tex]
Given the expression:
[tex] \displaystyle \large{4m + 5 - 3m}[/tex]
To simplify the expression, notice that 4m and 3m have the same term.
These are called like terms. Let's see some examples of like terms.
x and 58x both are like terms because they have same x.90y and 35664y both are also like terms because they have same y.Then we also have the example of non-like term
50 and x both are not like terms because 50 is a constant and not a variable and x is not a number.920x and 790y both are not like terms because both have different variables.x and x^2 are not like terms as well because different degrees.In conclusion,
like terms have to be the same term and same degree.And that brings us to this topic, to evaluate or simplify the expression with two like terms and one non-like term.
Note that only like terms can evaluate. Let's see some examples:
5x+9x would be 14x since they are like terms and thus can be evaluated.x+x would be 2x. x is equivalent to 1x so 1x+1x = 2x. They are also like terms as well.How about a subtraction?
9x-2x would be 7x. x-x would be 0.10y-7y would be 3y.But what if it's non-like terms? Simple, we keep it like that!
8y+8z would be the same. They are not like terms so they cannot be evaluated.10x-7 would be the same as well. Not like terms.So to simplify the expression in the question, we evaluate like terms first!
Since 4m and 3m both are like terms. We can do 4m-3m.
[tex] \displaystyle \large{4m + 5 - 3m} \\ \displaystyle \large{4m - 3m + 5} [/tex]
Evaluate 4m-3m
[tex] \displaystyle \large{1m + 5} [/tex]
We don't usually write 1m so we keep as m instead.
[tex] \displaystyle \large{m + 5} [/tex]
Now, can we evaluate m+5? No, because m and 5 are not like terms so we keep like this.
Hence, the answer is m+5
You borrow $7000 to help pay your college expenses. You agree to repay the loan at the end of 7 years at 9% interest, compounded quarterly. (Round your answers to two decimal places.)
(a) What is the maturity value of the loan?
Answer:
?
Step-by-step explanation:
So first, you need to multiply 7 by four to get the quarterly part of it, which will be 28. Then, multiply 9% (.9) by your 28 to get 25.2. Finally, multiply that by 7,000 to get 176,400...
If four times a certain number, increased by 6 is equal to 94, what is the number?
If x represents the number, then which of the following equations could be used to solve the problem?
4x + 6 = 94
x + 6 = 4(94)
4(x + 6) = 94
Answer:
4x + 6 = 94 could be used to solve the problem

y' - y/x+1 = 2
It looks like the differential equation is
[tex]y'-\dfrac y{x+1}=2[/tex]
Multiply both sides by 1/(x + 1) :
[tex]\dfrac{y'}{x+1}-\dfrac y{(x+1)^2} = \dfrac2{x+1}[/tex]
The left side is now a derivative of a product,
[tex]\left(\dfrac y{x+1}\right)' = \dfrac2{x+1}[/tex]
Integrate both sides with respect to x :
[tex]\dfrac y{x+1} = 2\ln|x+1|+C[/tex]
Solve for y :
[tex]y = 2(x+1)\ln|x+1| + C(x+1)[/tex]

is kElly's answer correct? what mistake did she make?
Answer:
No because she added 2 instead of 2398. She thought the 2 was separate because of the comma separating the 2 thousand. She also made a mistake by thinking she could add easily by adding 2 to 2398 to make 2400.
The addition of the given numbers is 7,758.
Use the concept of addition defined as:
In mathematics, addition is an arithmetic operation that combines two or more numbers to produce a sum.
It is a fundamental operation used to calculate the total or the result of combining quantities. When adding numbers, you start with the first number, and then incrementally add subsequent numbers to obtain a final sum. The order in which numbers are added does not affect the result, thanks to the commutative property of addition.
This fundamental concept of addition forms the basis for more advanced mathematical operations and problem-solving techniques.
The given numbers are:
5,356+2,398
Now simply add these numbers:
5 3 5 6
+2 3 9 8
7 7 5 4
Hence,
The addition of the given numbers is 7,758.
