If f(x)= x/2 and g(x) = 2x^2, find (f+g)(x)
A. 2x^3 + 3/2x+1
B. 2x^2 + 3/2x-5
C. x^2-6
D. 2x^2 + x/2+1
Answer:
B
Step-by-step explanation:
We have the two functions:
[tex]f(x)=\frac{x}{2}-2\text{ and } g(x)=2x^2+x-3[/tex]
And we want to find:
[tex](f+g)(x)[/tex]
This is the same thing as:
[tex]=f(x)+g(x)[/tex]
Let's substitute them for their respective equations. This yields:
[tex]=(\frac{x}{2}-2})+(2x^2+x-3)[/tex]
Combine like terms:
[tex]=(2x^2)+(\frac{x}{2}+x)+(-2-3)[/tex]
Add:
[tex]=2x^2+\frac{3}{2}x-5[/tex]
So, our answer is B.
And we're done!

You can read 63 pages of your book over 3 hours. What is the unit rate?
Answer:
21 pages per hour
Step-by-step explanation:
To find unit rate, we just divide the number of pages read by the time it took to read them. This will give us the number of pages read per hour, which is the unit rate:
63/3=21
The unit rate is 21 pages per hour.

Bob has a recipe for salad dressing the recipe says to mix 1/4 cup lemon juice. 1/8 cup mustard and 1/4 cup vinegar how much lemon juice does he need to make 4 cups of salad dressing show your work
Answer:
Step-by-step explanation:
1/4*x + 1/8*x + 1/4 * x = 4 cups
5/8 * x = 4 cups Multiply both sides by 8/5
5/8 * 8/5 x = 4 8/5
x = 32/5
x = 6.4
That means that each ingredient must be multiplied by 6.4
1/4 * 6.4 = 1.6 cups lemon juice
1/8 * 6.4 = .8 cups mustard
1/4 * 6.4 = 1.6 cups vinegar
Total = 4 cups.

Answer:
In general, an unresolved nth root, commonly involving a radical symbol ^n√x, is known as a surd. However, the term surd or "surd expression" (e.g., Hardy 1967, p. 25) can also be used to mean a sum of one or more irrational roots. In the mathematical literature, the term arises most commonly in the context of quadratic surds.

(5x + 4)° (8x – 710°
Answer:
x = 19
Step-by-step explanation:
Assuming the question was (5x + 4)° (8x – 71)°=180° not (5x + 4)° (8x – 710°,
Simplifying
(5x + 4) + (8x + -71) = 180
Reorder the terms:
(4 + 5x) + (8x + -71) = 180
Remove parenthesis around (4 + 5x)
4 + 5x + (8x + -71) = 180
Reorder the terms:
4 + 5x + (-71 + 8x) = 180
Remove parenthesis around (-71 + 8x)
4 + 5x + -71 + 8x = 180
Reorder the terms:
4 + -71 + 5x + 8x = 180
Combine like terms: 4 + -71 = -67
-67 + 5x + 8x = 180
Combine like terms: 5x + 8x = 13x
-67 + 13x = 180
Solving
-67 + 13x = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '67' to each side of the equation.
-67 + 67 + 13x = 180 + 67
Combine like terms: -67 + 67 = 0
0 + 13x = 180 + 67
13x = 180 + 67
Combine like terms: 180 + 67 = 247
13x = 247
Divide each side by '13'.
x = 19
Simplifying
x = 19

Answer:

Step-by-step explanation:
We know that the sum of the angles of a triangle is 180
HCA + CAH + AHB = 180
80+ CAH + 90 = 180
Combine like terms
170 + HAC = 180
HAC= 180-170
HAC = 10
We also know that HCA + ACB is a straight line so it adds to 180
HCA + ACB = 180
80+ACB = 180
ACB = 180-80
ACB = 100
Since ACB is isosceles the base angles have the same measure so CAB = ABC
We know that the sum of the angles of a triangle is 180
CAB + ABC + ACB = 180
Replacing ABC with CAB
CAB + CAB + 100 = 180
2CAB + 100 =180
2 CAB = 180-100
2 CAB = 80
Divide by 2
CAB = 80/2
CAB = 40
Now find HAB
HAB = HAC + CAB
= 10 + 40
= 50

find y if x is equal to 20
Answer:
Hope this help
Step-by-step explanation:
Plug in the y value found from the first equation in to the second equation in order to find the x value. In the previous example, this means the second equation becomes "x + 5(2- 3x) = 20"
Solve for x. The example equation becomes "x + 10 - 15x = 20," which is then "-14 x + 10 = 20." Subtract 10 from each side, divide by 14 and you have end up with x = -10/14, which simplifies to x = -5/7.
Plug in the x value in to the first equation to find out the y value. y = 2 - 3(-5/7) becomes 2 + 15/7, which is 29/7.

Suppose the manager of a gas station monitors how many bags of ice he sells daily along with recording the highest temperature each day during the summer. The data are plotted with temperature, in degrees Fahrenheit (°F), as the explanatory variable and the number of ice bags sold that day as the response variable. The least squares regression (LSR) line for the data is Yˆ = −114.05+2.17X. On one of the observed days, the temperature was 82 °F and 66 bags of ice were sold.
1. Determine the number of bags of ice predicted to be sold by the LSR line, Yˆ, when the temperature is 82 °F.
2. Compute the residual at this temperature.
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Equation of regression line :
Yˆ = −114.05+2.17X
X = Temperature in degrees Fahrenheit (°F)
Y = Number of bags of ice sold
On one of the observed days, the temperature was 82 °F and 66 bags of ice were sold.
X = 82°F ; Y = 66 bags of ice sold
1. Determine the number of bags of ice predicted to be sold by the LSR line, Yˆ, when the temperature is 82 °F.
X = 82°F
Yˆ = −114.05+2.17(82)
Y = - 114.05 + 177.94
Y = 63.89
Y = 64 bags
2. Compute the residual at this temperature.
Residual = Actual value - predicted value
Residual = 66 - 64 = 2 bags of ice

The perimeter of a scene triangle is 14.5 cm. The longest side is twice that of the shortest side. Which equation can be used to find the side lengths if the longest side measures 6.2cm?
Answer:
[tex]\huge\boxed{6.2 + (\frac{6.2}{2}) + x = 14.5}[/tex]
Step-by-step explanation:
To create an equation for this, we have to note a couple of things.
A scalene triangle has 3 different length sidesAll sides will add up to the perimeter (in this case 14.5)We know that the longest side is 6.2 cm long. We also know that the longest side is twice the length of the shortest side. Therefore, the shortest side will be half the amount of the longest side.
Basically - we divide the longest side by 2 (6.2) so [tex]\frac{6.2}{2}[/tex].
We don't know the third side. However, we know the total perimeter (14.5). Therefore, we can use a placeholder for the third side - [tex]x[/tex].
Adding up all the sides, we have [tex]6.2 + (\frac{6.2}{2}) + x = 14.5[/tex].
