Answer:
Any, that is greater than 5 and less than 17Step-by-step explanation:
Given three sides of triangle: a, b and c, and a<c and b<c, then the triangle exist only if a+b>c
therefore:
if a = 11 and b = 6 and c = ??
then: 11 + 6 > c
c < 17
if a = 6 and c = 11 and b = ?? {or b=6 and a=??}
then: 6 + b > 11 {subtract 6 from both sides}
b > 5
Function or not?

Answer:
y*y*y*y*y
y^5
Step-by-step explanation:
When you multiply exponents with the same base you're supposed to add them so your answer to the first is y^5 but your teacher is being weird and wants you to write it with no exponents so you can just write it 5 times
so number one is y*y*y*y*y
I answered number two in my explanation above
you add the exponents
y^2+y^3=y^5

If Maggie saves 10% off a t-shirt that normally costs $13 and 25% off a pair of boots that normally cost $40, how much in total did she save?
Answer:
Maggie saved $11.30 Dollars
Step-by-step explanation:
The answer is 11.30 because 10% of 13 is 1.3 because 13 divided by 10 is 1.3
and 25% of 40 is 10. So, 10 plus 1.3 is 11.30 dollars

Answer:
216 Minutes
Step-by-step explanation:
2x=18
x=9
Every mile is 9 minutes, so we can multiply 9 by 26:
234 minutes
But he has already ran for 18 minutes, so we can subtract:
234-18=216
Answer:
216mins
Step-by-step explanation:
first divide 2/18 by 2 to see the rate and you get 1/9 so he runs 1 mile every 9 mins. You multiply 9 by 26 to get your answer and you get 234 subtract 18 and it will take him 216 more mins
completely factor the polynomial: 9x+ay+9y+ax
Answer:
(x + y)(a + 9)
Step-by-step explanation:
Here, we want to factorize the polynomial
We can do this by taking together like terms
Thus. we have that;
9x + ax + ay + 9y
= x(a + 9) + y(a + 9)
= (x+y)(a+ 9)

If QR is 17 more than twice x, RS is 19 less than six times x, and QS is one less than four times x, find x and the measure of each side
Complete question :
triangle QRS is an equilateral triangle. If QR is seventeen more than twice x, RS is 19 less than six times x, and QS is one less than four times x, find x and the measure of each side.
Answer:
x = 9
All sides have 35 units length
Step-by-step explanation:
Recall: Equilateral triangles have 3 sides, all of equal length.
QR = 2x + 17
RS = 6x - 19
QS = 4x - 1
Take :
QR = RS = QS
To find x
QR = RS
2x + 17 = 6x - 19
2x - 6x = - 19 - 17
-4x = - 36
x = 9
QR = 2(9) + 17 = 35
RS = 6(9) - 19 = 35
QS = 4(9) - 1 = 35

Step-by-step explanation:
There are several ways you can go about this. The most straight-forward (and time-consuming) is to use a calculator to calculate the value for each cell of the table.
If you realize that the first row will be the base of the exponential, then you can finish filling that easily. The first row is completed by ...
4^1 = 4, 5^1 = 5.
Each row below that is the immediately preceding row multiplied by the number in the first row. For example, to finish the second column, we have ...
2^4 = 2·8 = 16
2^5 = 2·16 = 32
__
When calculations are easily defined and repetitive, I like to use a spreadsheet to do them. It avoids errors, and (to me) is less tedious than repeating the same calculation over and over. The first row of this spreadsheet is sequential numbers, as described above. The remaining cells raise the first row value to the left column power.

Check all that apply.
HELP ME NOW PLEASE DONT GIVE A FAKE ANSWER PLEASEEEEEEEEEE
Answer:
y = 22; x = 8
y > x
Step-by-step explanation:
A larger number is double the sum of 3 and a smaller number. The larger number is 2 less than 3 times the smaller number. If y represents the larger number and x represents the smaller number, which equations model the situation? Check all that apply.
Let
Smaller Number = x
Larger number = y
larger number is double the sum of 3 and a Smaller number
Sum of 3 and a smaller number = 3 + x
y = 2(3 + x)
y = 6 + 2x (1)
Also
y = 3x - 2 (2)
Equate the equation of the larger number
6 + 2x = 3x - 2
6 + 2 = 3x - 2x
8 = x
x = 8
Substitute x = 8 into (1) to find y
y = 6 + 2x (1)
y = 6 + 2(8)
= 6 + 16
= 22
y = 22
y = 22; x = 8
Therefore,
y > x

A museum sold 95 tickets for $1,025. Each adult ticket was $15, and each child ticket was $7. Let a represent the number of adult tickets sold and let c represent the number of child tickets sold. Which system of equations can be used to determine the numbers of tickets sold?
Answer:
a + c = 95........eq1
15a + 7c = 1,025....eq2
Step-by-step explanation:
Given:
Total number of ticket sold = 95
Total amount collected = $1,025
Price of each adult ticket = $15
Price of each child ticket = $7
Computation:
Number of adult tickets sold = a
Number of child tickets sold = c
So,
Number of adult tickets sold + Number of child tickets sold = Total number of ticket sold
a + c = 95........eq1
and
15a + 7c = 1,025....eq2

A rectangular shaped living room bas dimensions of 32 feet by 18 feet. What is the length of the diagonal? Round your answer to the nearest tenth, if necessary.
Answer:
D = 36.7 feet
Step-by-step explanation:
Diagonal of a Rectangle
Given a rectangle of width W and length L, its diagonal can be calculated as the hypotenuse of a triangle of legs W and L as follows:
[tex]D=\sqrt{W^2+L^2}[/tex]
The dimensions of the living room are 32 feet by 18 feet, thus the diagonal is:
[tex]D=\sqrt{32^2+18^2}[/tex]
[tex]D=\sqrt{1024+324}=\sqrt{1348}[/tex]
D = 36.7 feet

Luis worked 40 hours last week and earned a total of $528. His job at Cub pays $9 per hour and
his job at Target pays $15 per hour. Set up a system of equations to determine how many hours
he worked at Cub and how many hours he worked a Target. Then, solve the system.
The number of hours worked at Cub is
The number of hours worked at Target is
Answer:
Let the number of hours he worked at his weekday job be x and the number of hours he worked at his weekend job be y, then
From (1): 25 + y = 40
y = 40 - 25 = 15.
Therefore, Beneio worked for 25 hours at his weekday job and 15 hours at his weekend job.

The longer leg of a right triangle is 4 more than the short leg. The hypotenuse is eight less than the sum of the 2 legs.
Solve
Answer:
SteLet a = short leg of the right triangle, b = the longer leg, and c = the hypotenuse.
The longer leg of a right triangle is 4inches longer than the shorter leg: b = a + 4
The hypotenuse is 8inches longer than the shorter leg: c = a + 8
Use the Pythagorean Theorem:
a2 + b2 = c2
a2 + (a+4)2 = (a+8)2
a2 + a2 + 8a + 16 = a2 + 16a + 64
a2 - 8a - 48 = 0
Factors to:
(a-12)(a+4) = 0
a = 12, -4
Since we can't have a side of -4, a = 12
Shorter Leg = 12 inches
Longer Leg = 12 + 4 = 16 inches
Hypotenuse = 12 + 8 = 20 inches
if a function has a verticale asymptote at a certain x-value, then the function is at the value
Answer:
We conclude that If a function has a vertical asymptote at a certain x-value, then the function is undefined at the value.
Step-by-step explanation:
If a function has a vertical asymptote at a certain x-value, then the function is undefined at the value.
For example, let the function
[tex]f\left(x\right)\:=\frac{x+3}{x-3}[/tex]
It is clear that the given function becomes undefined at x = 3 in the denominator.
i.e. 3-3 = 0
It means, the function can not have x = 3, otherwise, the function will become undefined.
In other words, if the function has a vertical asymptote at x = 3, then the function is undefined at the value.
Therefore, we conclude that If a function has a vertical asymptote at a certain x-value, then the function is undefined at the value.
solve by substitution 6x-4y=18, -x-6y=7
Answer:
(2,-1.5)
Step-by-step explanation:
6x-4y=18
-x-6y=7
Switch the second equation from standard form to y=mx+b form
-x-6y=7→ -x=7+6y → multiply both sides by -1→ x=-7-6y
Substitute all of the things that equal x into the other equation into x
6x-4y=18→ 6(-7-6y)-4y=18
Simplify
-42-36y-4y=18
Bring - 42 to the other side and add like terms
-42-36y-4y=18→ -40y= 60
Solve for y
y=-1.5
Choose an equation and plug y in it.
-x-6(-1.5)=7
-x+9=7
-x=-2
Multiply both sides by -1
x=2
