Answer:
C
Step-by-step explanation:
Given f(x) then f(x + a) is f(x) translated horizontally
• If a > 0 then a shift to the left of a units
• If a < 0 then a shift to the right of a units
Given that h(x) = g(x - 3) , then
The graph of h(x) is the graph of g(x) horizontally shifted 3 units right

Please help me! I cant figure this out
AB is the same as A multiplied by B. In order to get this value, we need to figure out the value of A and B.
We have two equations here:
a + 5b = 2b + 13
a = 3b - 5
The second equation already has A isolated. So, we can take that equation and plug in the value for A. Doing so will allow us to solve for B.
(3b - 5) + 5b = 2b + 13
8b - 5 = 2b + 13
6b - 5 = 13
6b = 18
b = 3
Now that we know B, we can use our equation that isolated A.
a = 3(3) - 5
a = 9 - 5
a = 4
Therefore, a = 4 and b = 3, and ab = 12.
Hope this helps!
9/8x²+2x-15 - 5/2x³+3x + 4/4x²-5x
Answer:
[tex]-\frac{5}{2} x^{3} +\frac{17}{8} x^{2} -15[/tex]
Step-by-step explanation:
First combine like terms so for numbers with x^3 you have one:
-[tex]\frac{5}{2} x^{3}[/tex]
Then x^ 2
[tex]\frac{9}{8}x^{2} +x^{2}[/tex]
(4/4x^2 is just x^2 because 4/4 is 1)
So
[tex]\frac{17}{8} x^{2}[/tex]
Then all numbers with x cancel out because
2x+3x-5x is 0.
Then you just have -15.
So put them back together to get what I wrote in the answer.
Hope that helps lmk if I calculated that wrong!
1 Which one of the following expression represents the sum of the expressions (5x - 13xy + 14y) and (12xy - 6x - 12y)?
Answer:
(12xy-6x -12y)
12xy-18xy
6xy
Answer:
- xy - x + 2y
Step-by-step explanation:
5x - 13xy + 14y + 12xy - 6x - 12y ← collect like terms
= (- 13xy + 12xy) + (5x - 6x) + (14y - 12y)
= - xy - x + 2y
sec²x + cosec²x ≡sec²xcosec²x
proving qn pls i nd it by tdy
Step-by-step explanation:
sec²x + cosec²x = sec²x.cosec²x
1/cos²x + 1/sin²x = 1/cos²x.1/sin²x
or, (sin²x+cos²x)/sin²x.cos²x = 1/(sin²x.cos²x)
or, 1/(sin²x.cos²x) = 1/(sin²x.cos²x)
Hence,
sec²x + cosec²x = sec²x.cosec²x proved!!

Find the value of the expression:
Answer:
3.6
Step-by-step explanation:
Hi there!
We are given this expression:
.6√36 (.6*√36)
And we want to find the value of it
.6 can be re-written as 0.6
In that case,
0.6*√36
First, simplify what's under the radical: √36, which is equal to 6 (6*6=36)
The expression then becomes:
0.6*6
Multiply those numbers together
0.6*6=3.6
Hope this helps!
Find the distance between the points (-2, -10) and (-9,-5) on a coordinate plane.
Answer:
√74
Step-by-step explanation:
Good Afternoon. I hope you’re well:) I need to understand how to go about solving this without a calculator, please. Thank you so much and have a blessed day!
Answer:
Step-by-step explanation:
Being able to do this requires that you understand what is being asked and that you understand domain. This is a piecewise function, made up of 4 different parts, and each part has a domain different from every other part. Now look at the solutions. We are given coordinates, x and y. So this is how this problem is done.
In a. the coordinate is (-1, 1), right? x = -1 here, so the equation that we "pick" (I'll explain that in a sec) has to have a domain where -1 will fall. The first part of this piecewise has a domain of less than or equal to -11. Is -1 less than or equal to -11? No, it is not. -1 is greater than -11, so the equation we "pick" to use will not be this one. Look at the next piece of the function and note its domain. This domain is that x is greater than -11 and less than 5. Does -1 fit in that domain? Is -1 included in that spread of numbers? Yes it is, so that is the equation we will use. By use I mean that we will plug in -1 for x and see if y = 1 (that number comes from the coordinate (-1, 1) where y = 1). The equation is y = x + 2 and plugging in -1 for x:
y = -1 + 2 so
y = 1 and this point is on the piecewise. Let's do one more example so you can see how it looks when it DOESN'T work out, ok?
Look at b. The coordinate is (-2, -10). x = -2, so the same domain, same equation: x + 2. We plug in -2 for x to find y:
y = -2 + 2 so
y = 0. 0 does not equal -10, so this point is not on that graph.
The key here is picking the equation whose domain includes your x value and evaluating the equation at that value of x to find y.

Answer:
[tex]y = 3x^2-24x+40[/tex]
Step-by-step explanation:
Hi there!
Standard form: [tex]y=ax^2+bx+c[/tex]
[tex]y = 3(x-4)^2-8[/tex]
Solve [tex](x-4)^2[/tex]
[tex]y = 3(x^2-8x+16)-8[/tex]
Multiply 3 by the parentheses
[tex]y = 3x^2-24x+48-8\\y = 3x^2-24x+40[/tex]

Solve the equation. Type the value of the variable in the answer box below. (Note: repeating decimals should be entered into the answer box as improper fractions.)
88=10+30−4
Answer: y = 9⅓
Step-by-step explanation:
The equation given here is
88 = 10y + 30 - 4y
The first thing to do is to collect terms
88 - 30 = 10y - 4y.
58 = 6y
Divide both side by 6
6y = 58
6y/6 = 58/6
y = 9 ⅓
Therefore, the value of y is 9⅓.
Find the value of x that will make L||M.

Answer:
6x+8+4x+2=180
so!! 10x+10=180
10x=170
x=17
Answer:
[tex]x=17[/tex]
Step-by-step explanation:
The two angles labelled [tex]6x+8[/tex] and [tex]4x+2[/tex] are co-interior angles. When two parallel lines are cut by a traversal, co-interior angles are supplementary, meaning they add up to 180 degrees. Therefore, if line L is parallel to line M, [tex]6x+8[/tex] and [tex]4x+2[/tex] must be supplementary:
[tex]6x+8+4x+2=180[/tex]
Combine like terms:
[tex]10x+10=180[/tex]
Subtract 10 from both sides:
[tex]10x=170[/tex]
Divide both sides by 10:
[tex]x=\frac{170}{10}=\boxed{17}[/tex]

If Tanya cleans a 1500 square foot building for a total of $107.00, what is the amount Tanya gets paid per square foot?
Answer:
Tanya will get approximately $0.07 per square foot.
This can be solved by creating a ratio between the amount she is paid and the amount of square feet she cleans.
(1500)/(107)=(1)/(x) = 0.0713
Answer:
0.0713
Step-by-step explanation:
Tanya will get approximately $0.07 per square foot.
This can be solved by creating a ratio between the amount she is paid and the amount of square feet she cleans.
(1500)/(107)=(1)/(x) = 0.0713

n is a whole number such that 6< 3n < 15 List all the possible values of n.
Answer:
3, 4
Step-by-step explanation:
6 < 3n < 15
Divide the three "sides" by 3.
2 < n < 5
n must be between 2 and 5,a nd it must be a whole number.
n can be 3 or 4
Answer:
n= 3, and n=4
Step-by-step explanation:
whole numbers are : 0,1,2,3,4,5,....
6 < 3n < 15
(3n has to be greater than 6 and less than 15 not including 6 and 15)
for n=3 we have 3n =9
for n=4 we have 3n= 12
Your cellphone plan is by the minute . Each minute of use costs $0.10 . Create a relation that represents the amount spent ,A, per minute ,m, of call time . Then, use the relation to find the amount spent if you talk 65 minutes. Show your work.
Answer:
Talking 65 minutes, $ 6.50 must be paid.
Step-by-step explanation:
Since your cell phone plan is by the minute, and each minute of use cost $ 0.10, to create a relation that represents the amount spent, A, per minute, m, of call time, and then use the relation to find the amount spent if you talk 65 minutes, the following calculations must be performed:
0.10 x M = A
0.10 x 65 = A
6.50 = A
