Answer:
Alright so on this type of problem you just perform the operation they ask for, which in this case is subtraction.
Your first step will be to set up the problem:
f(x) - g(x)
Next you will substitute in your values:
(2x + 1) - (x2 - 7)
The easiest way to do the subtraction problems is to distribute your negative into your second set of parenthesis, so your expression would become:
2x + 1 - x2 + 7
Then combine your like terms:
2x - x2 + 8
Lastly put your expression in standard form (highest exponent to lowest)
-x2 + 2x + 8

If triangle ABC is similar to triangle PQR, find the value of x and y.
Answer:
x = 9
y = 6
Step-by-step explanation:
ΔABC ~ ΔPQR
Therefore, corresponding sides of these similar triangles will be in the proportional.
[tex]\frac{AB}{PQ}=\frac{BC}{QR}= \frac{AC}{PR}[/tex]
[tex]\frac{6}{x}= \frac{4}{y}= \frac{8}{12}[/tex]
[tex]\frac{6}{x}= \frac{8}{12}[/tex]
x = [tex]\frac{12\times 6}{8}[/tex]
x = 9
Similarly, [tex]\frac{4}{y}= \frac{8}{12}[/tex]
y = [tex]\frac{12\times 4}{8}[/tex]
y = 6

Find:
5% of 90 m =
m
25% of 88 kg =
kg
75% of 264 =
Answer:
1) 5% of 90m= 4.5m
2)25% of 88kg = 22kg
3) 75% of 264= 198
Step-by-step explanation:
1) 90m = 100% (divide by 10)
9 = 10% (divide by 2)
4.5 = 5%
2) 88kg = 100% (keep on dividing by 2)
44kg = 50%
22kg=25%
3) 264 = 100%
132 = 50%
66 = 25% (add)
198=75%

Find the area of the figure.
7 cm
8 cm
11 cm
The area is
square centimeters.
Answer:
let's divide the figure in rectangle and triangle.
first we should find the area of triangle.
area of triangle =1/2×base×height
area of triangle=1/2×11cm×7cm
area of triangle=38.5cm²
area of rectangle =length ×width
area of rectangle =11cm×8cm
area of rectangle =88cm²
area of the figure=38.5cm²+88cm²
area of the figure=126.5cm²

Your restaurant bill comes to $46.27. Estimate a 10% tip.
If the bill of the restaurant comes to $46.27 then the tip of 10% is equal to $4.627.
What is percentage?Percentage is number or ratio that is expressed as a fraction of 100. It is shown by % sign. It shows some quantity over other quantity. The number which shows the percentage is the number in the quantity itself.
How to calculate percentage?We have been given that the bill of the restaurant comes to $46.27 and 10% is the tip. We have to calculate the tip.
Tip=Bill*10/100
=46.27*10/100
=4627*10/100*100
=46270/10000
=$4.627
Hence if the bill of the restaurant is $46.27 then tip will be $4.627.

Solve the equation. Show the process, not just an answer. 6.EE.7
1) 4k = 24
2) 34 + h = 60
3) 1/5x = 30
4) m-42 = 85
Isolate the variable, note the equal sign, what you do to one side, you do to the other.
1) 4k = 24
Isolate the variable, k. Divide 4 from both sides of the equation:
(4k)/4 = (24)/4
k = 24/4
k = 6
2) 34 + h = 60
Isolate the variable, h. Subtract 34 from both sides of the equation:
34 (-34) + h = 60 (-34)
h = 60 - 34
h = 26
3) 1/5x = 30
Isolate the variable, x. Multiply 5 to both sides of the equation:
(5) * (1/5)x = (30) * (5)
x = 30 * 5
x = 150
4) m - 42 = 85
Isolate the variable, m. Add 42 to both sides of the equation:
m- 42 (+42) = 85 (+42)
m = 85 + 42
m = 127

The graph shows the relationship between the distance a car is driven and the number of gallons of gasoline used. Identify the value in d in the point (1, d). What does that point represent?
A. d=25; the unit rate is 25 miles per gallon
B. d=25; the unit rate is 25 gallons per mile
C. d=50; the unit rate is 50 miles per gallon
D. d=50; the unit rate is 50 gallons per mile
Answer:
A. d = 25; the unit rate is 25 miles per gallon
Step-by-step explanation:
The point (1, d) on the graph represents (x, y), where,
x = gasoline used = 1 gallon
y = distance = d = 25 miles
That is, (1, d) represents when x = 1, y = 25.
Thus, (1, 25) is the unit rate which is 25miles per gallon.
