Without drawing the graph of the function y=1.2x−7, see if the graph passes through points: (100; 113)
Answers
Answer:
(100,113) is on the graph of y = 1.2x -7
Step-by-step explanation:
y=1.2x−7
Substitute the point in and see if the equation is true
113 = 1.2 (100) -7
113 =120 - 7
113 = 113
This is true, so the point is on the graph

The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answers
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143

Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30
(2x+7) x = 30
you can distribute to make this easier
2x^2 + 7x = 30
you can plug this into quadratic formula by setting the equation =0, so:
2x^2 +7x -30 = 0
where 2x^2 = a
7x = b
and -30 = c
you can plug this into your calculator and get an answer of
X = 2.5

Step-by-step explanation:
First of all, it says you can use a calculator! If you do not know how to, let me know in the comments and I can try to help you out! Read the explanation to understand how to do this.
Question 17
Using a calculator, you get 6.48074069… for your decimal.
Rounding it to the nearest tenth, your answer would be 6.5
Now, to find the two consecutive whole numbers the square root is between…
However, there is another way to do this. Remember that 7x7=49. We know that 49 is greater than 42, so let’s see try out a number smaller than 7! 6x6=36. 42 is between 36 and 49, so the square root is between 6 and 7.
Another way to do this is… we know that the decimal is about 6.5, which is between 6 and 7, since those are the two whole numbers before and after that decimal!
Question 18
Using a calculator, you get 9.380833151… for your decimal.
This rounds to 9.4
The whole numbers surrounding this decimal are 9 and 10.
You can also do this by knowing that 9x9, or 9^2, is 81 and 10x10, or 10^2, is 100, and those are the numbers surround 88.
In non-decimal form (simplified radical), your answer can be 2√22.
Question 19
Using a calculator, you get 7.93725393… for your decimal.
This rounds to 7.9
The whole numbers surrounding this decimal are 7 and 8.
You can also do this by knowing that 7x7, or 7^2, is 49 and 8x8, or 8^2, is 64, and those are the numbers surround 63.
In non-decimal form (simplified radical), your answer can be 3√7.
Question 20
Using a calculator, you get 8.66025403… for your decimal.
This rounds to 8.7
The whole numbers surrounding this decimal are 8 and 9.
You can also do this by knowing that 8x8, or 8^2, is 64 and 9x9, or 9^2, is 81, and those are the numbers surround 75.
In non-decimal form (simplified radical), your answer can be 5√3.
Question 21
Using a calculator, you get 5.47722557… for your decimal.
This rounds to 5.5
The whole numbers surrounding this decimal are 5 and 6.
You can also do this by knowing that 5x5, or 5^2, is 25 and 6x6, or 6^2, is 36, and those are the numbers surround 30.
Question 22
Using a calculator, you get 9.84885780… for your decimal.
This rounds to 9.8
The whole numbers surrounding this decimal are 9 and 10.
You can also do this by knowing that 9x9, or 9^2, is 81 and 10x10, or 10^2, is 100, and those are the numbers surround 97.
Note: the symbol "^" means that the number following that symbol is an exponent. So 2^2 is 2 squared, \(2^2\), or 2 to the power of 2.

Isabella spends $4.50 on poster boards. How many poster boards does she buy?
Isabella buys poster boards.
Part 2 out of 2
Isabella spends $7.80 on paint brushes and paint. How many of each item does she buy? Complete the explanation how you found your answer.
By using compatible numbers, you find a total of items that had a total cost of $7.80. Then you used guess and check to find that she buys paint brushes and jars of paint.
Answers
Answer:
6 poster boards3 paint brushes, 5 jars of paintStep-by-step explanation:
Given poster boards are $0.75 each, you want to know the number purchased for $4.50. Given brushes are $0.95 and jars of paint are $0.99, you want to know the number of each purchased for $7.80.
1.The total price is the quantity times the price each:
4.50 = q × 0.75
q = 4.50/0.75 = 6
Isabella buys 6 poster boards.
2.Compatible numbers for the costs of brushes and paint are each 1. A compatible number for the total purchase is 8. This tells us Isabella bought 8 items for 7.80. This gives two equations in two unknowns:
0.95b +0.99p = 7.80
b + p = 8
Substituting for b, we have ...
0.95(8 -p) +0.99p = 7.80
`7.60 +0.04p = 7.80 . . . . . . simplify
0.04p = 0.20 . . . . . . . . . . . subtract 7.60
p = 0.20/0.04 = 5
b = 8 -5 = 3
Isabella buys 3 paint brushes and 5 jars of paint.
Check
0.95(3) +0.99(5) = 2.85 +4.95 = 7.80 . . . . answer checks OK
__
Additional comment
Note that we do not need to "guess and check" once we know the number of items purchased.
Or, we can "guess" without the business of compatible numbers by realizing the number of jars must be a multiple of 5 if the total purchase is a multiple of 5 cents. That leaves one possibility, since 10 jars is too many, and 0 jars is not enough.

In the rectangle below, the line MN cuts the rectangle into two regions. Find x, the length of segment NB, so that the area of the quadrilateral MNBC is 40% of the total area of the rectangle.
Answers
The length of segment NB is 0.833
Finding x, the length of segment NBFrom the question, we have the following parameters that can be used in our computation:
The rectangle
The area of the rectangle is
Area = (20 + x) * 10
The area of MNBC is
Area = 1/2 * 10 * (x + 20 + x - 5)
Area = 5(2x + 15 )
The area of the quadrilateral MNBC is 40% of the total area of the rectangle
So, we have
5(2x + 15) = 40% * (20 + x) * 10
5(2x + 15) = 4* (20 + x)
When evaluated, we have
x = 0.833

Answers
Answer: x=108 degrees
Step-by-step explanation:
Since ST is a straight line, it measures 180 degrees.
This means that
x+(2/3)x=18
The simplified version is 5x/3=180. Now, we multiply both sides by 3. The equation becomes 5x=540 you would divide 5 by both sides which is ultimately x=108.
Answer:
x=108 degrees
Step-by-step explanation:
We know that since ST is a line, it equals a total of 180 degrees.
Let's write an equation:
\(180=x+\frac{2}{3}x\)
simplify
\(180=\frac{5}{3} x\)
divide both sides by 5/3
108=x
So, x=108 degrees.
