Step-by-step explanation:
First Question:
[tex]\sqrt{100}[/tex] + [18 ÷ 3 x 4 - 15] - (60 - 7^2 - 1)
[tex]\sqrt{100}[/tex] + [24 - 15] - (60 - 49 - 1)
[tex]\sqrt{100}[/tex] + 9 - 10
10 + 9 - 10
Answer = 9
Second Question:
5x + 2x = 7x
5x^2 + 3x^2 = 8x^2
2x + 3x - x = 4x
2x + 3y + x + y = 3x + 4y
9x - 6x = 3x
-7y + 3x + 4x + 3y = 7x - 4y
-7x^2 + 2x^2 + 9x^2 = 8x^2
(3x^2 + 5x + 4) - (-1 + x^2) = 2x^2 + 5x + 5
(3 + 2x - x^2) + (x^2 + 8x + 5) = 10x + 8
(3x - 4) - (5x + 2) = -2x - 6
(2x^2 + 5x + 3) - (x^2 - 2x + 3) = x^2 + 7x
(3x^2 + 2x - 5) - (2x^2 - x - 4) = x^2 + 3x - 1
Third Question:
17x + 2y
(5x + 12y) + (3x + y) = 8x + 13y
17x - 8x = 9x
2y - 13y = -11y
Answer: 9x - 11y

Answer:
A = (1, 10)
B = (4,10)
C = (4, 14)
D = (1, 16)
Step-by-step explanation:
Okay, so first, we move, or translate the quadrilateral PQRS down -8 spaces on the graph, turning old points:
P (1, -2) = (1, -10) Q (4, -2) = (4, - 10) S (1, -8) = (1, -16) and R (4, -6) = (4, -14)
Now, we need to rotate this new box into -x, y. So our new points are:
(1, -10) = (-1, 10) (4, -10) = (-4, 10) (1, -16) = (-1, 16) and (4,-14) = (-4, 14)
Now we're reflecting off the y-axis, making our x change. So for our final points:
A(1, 10) B (4,10) D(1, 16) and C(4, 14)
Hope this helps! Please check my math and comment wether this worked or not! :)

A car rental agency advertised renting
drive on a $100 budget?
car for $28.95 per day and $0.25 per mile. If Shawn rents this car for 3 days, how many whole miles can he
miles solve
Answer:
He could drive 52.006 miles
Step-by-step explanation:
Multiply 28.95 by 3. You get 86.85Subtract 86.85 from 100. You get 13.15Divide 13.15 by 0.25. You get 52.006Heyyyyyyyyyyyyyyyyyyyyyy

which expression is equavilent to 4/5x+(-2)+(-6)-1/5x
Answer:
3/5x - 8
Step-by-step explanation:
4/5x + (-2) + (-6) - 1/5x
4/5x - 1/5x = 3/5x
(-2) + (-6) = -8
3/5x - 8 is the answer

If given 5 miles is 8km convert 13.5 miles into km
Step-by-step explanation:
There are 2 ways we can do this. We can use our friend which we will call a special device or we could actually solve using formulas we already know. Today, I will be using a formula but you can easily just use the secret device.
Step 1: Knowing the formula which is multiply miles by 1.609 and then round to the nearest tenth or hundredth.
13.5 X 1.609 = 21.7215.
Round down to 21.7.
Final Answer: 21.7 Km is equal to 13.5 miles or vice versa.

Perpendicular lines have the product of their gradient equal to -1
For L1,the gradient is 3
For L2,we express in slope-intercept form
6y=1-2x
y=1/6-⅓x
The slope is -⅓
Now product of both slopes 3×-⅓=-1,thus the lines are perpendicular

Colleen buys a robot priced at $33.If the sales tax is10%,how much tax will Colleen pay?
Answer:
$3.3 tax
Final price is 36.3
Step-by-step explanation:
Firstly, if the tax is expressed in percent, divide the tax rate by 100. You can do this by simply moving the decimal point two spaces to the left. In this example, we do 10/100 = 0.1
tax= 33 * 0.1
tax=3.3
Finally, add tax to the before tax price to get the final price including tax.
The final price including tax = 33 + 3.3 = 36.3

Answer:
( 2 − 3 ) ( − 1 )
Step-by-step explanation:
Consider this function.
h(x) = (x - 2)^2+3
Which of the following domain restrictions would enable h(x) to have an inverse function?
a. x < 1
b. x ＞5
c. x < 3
d. x > 4
(Ps: all four answer and larger equal then or smaller equal then
Answer:
No inverse function: (a), (b), (c)
Inverse function exists: (d)
Step-by-step explanation:
The graph of h(x) = (x - 2)^2 + 3 is a parabola that opens upward and has vertex at (2, 3). If the entire graph is drawn, and the horizontal line test then applied, h(x) would not have an inverse, because the horizontal line would intersect the parabolic graph twice.
Note that if we restricted the domain to x ≥ 2, the resulting graph would pass the horizontal line test. This would also be true for x ≥ 3, x ≥ 4, and so on. Not so for (a) x < 1. False for x > -5. True for x < 3. True for x > 4.
No inverse function: (a), (b), (c)
Inverse function exists: (d)

does any one know the Inequality Notation for this [9,∞)
Answer:
x>=9
Step-by-step explanation:
so, we can plot this on a number line
the point at 9 is a solid dot, since brackets (not parenthasis) indicates that we including the number. the shaded part of the line extends all the way to positive infinity. the shaded part means that it is a solution, while the un-shaded parts aren't solutions to [9,infinity) it is x>=9 and not x>9 because 9 is included.
x>=9 is the answer

Which angles are adjacent to each other? Question is located in the attached file (image)
Answer:
∠ 1 and ∠2
Step-by-step explanation:
Adjacent angles share a common ray or side between them, and have the same vertex.
Therefore, the adjacent angles from the given image are: ∠ 1 and ∠2.
The other given options are not adjacent angles because they do not have the same common vertex and ray.

Question 3 "Try Again." Mary needs 3 feet of boondoggle for a craft project.
Boondoggle costs $0.25 per inch. How much will the project cost Mary?
Answer:
$9.00
Step-by-step explanation:
We can use conversion factors to solve this equation. The multiplication sequence that I got is shown below:
[tex]\frac{3ft}{1}[/tex] × [tex]\frac{12 in}{1ft}[/tex] × [tex]\frac{0.25}{1in}[/tex]
Our feet and inches cancel out and we get the final expression [tex]\frac{3*12*0.25}{1}[/tex], which is equal to 9, or $9.00.
Hopefully that was helpful! :)

What is the ratio of the number of beaks to the number of legs the chickens and the sheep have on this farm?
Answer: 1:9
Step-by-step explanation:
If you multiply 2 legs times 8 chickens we get 16
If you multiply 4 legs times 14 sheep we get 56
The number of legs is 16+56=72
So you have 8 beaks and 72 legs or 8:72
Divide both sides by 8 to simplify and you get 1:9 as the answer
Jonas has bought three t-shirts. Each t-shirt was the same price. After using a 10% off coupon the total charge was 95 what was the cost of each t-shirt
Answer:
35 5/27
Step-by-step explanation:
You just have to set up an equation:
0.9/95 = 1/x
And if you cross-multiply, you get:
0.9x=95
Which means x is 95/0.9 which is 105 5/9. So, if all three t-shirts costed 105 5/9, and they all costed the same, then one t-shirt costs 35 5/27.
