if h(x) = x^2-5x+7 find each value
1/3*h(-8)
Answers
if h(x) = [tex]x^{2} -5x+7[/tex] so the value of [tex]\frac{1}{3}[/tex]× [tex]h(-8)[/tex] = [tex]\frac{111}{3}[/tex].
A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. The meanings of the word equation and its cognates in other languages can vary slightly. For instance, in French, an equation is defined as having one or more variables, whereas, in English, an equation is any well-formed formula that consists of two expressions linked by the equals sign.
Finding the values of the variables that result in equality is the first step in solving an equation with variables. The variables that must be included in the equation are also known as the unknown.
we have h(x) = [tex]x^{2} -5x+7[/tex]
So, substitute the value [tex]x=-8[/tex] in the equation,
h([tex]-8[/tex]) = [tex](-8)^{2} -5(-8)+7[/tex]
= [tex]64+40+7[/tex]
= [tex]111[/tex]
And now we shall multiply it with [tex]\frac{1}{3}[/tex],
we get, [tex]\frac{1}{3}[/tex]× [tex]h(-8)[/tex] = [tex]\frac{111}{3}[/tex]

Answers
Answer: n=6
Step-by-step explanation:
First you subtract 18 from both sides so that it become -1/2n^2=-18
Second divide both sides by -1/2 so it becomes -18/(-1/2)=n^2
Then you simplify and get n^2=36
Finally you find the square root of both side, and you get n=6

If 2 pints = 1 quart, how many pints are in a 26-quart container
Answers
Answer:
52 pints
Step-by-step explanation:
Given;
2 pints = 1 quart
To Find;
How many pints are in a 26-quart container
Solve;
Since 2 pints = 1 quart
Then the Formula = divide the volume value by 2
The equation for 2 pints = 1 quart is 2 ÷ x = 1
which x = 2.
Thus, the equation for 26 quart container = how many pints =
x ÷ 2 = 26
Divide/Multiply sides by 2
2x/2 = 26 * 2
Simplify
x = 52
Hence, there are 52 pints in a 26 quart container

Find the area
Answers
Answer:
240 square feet
Step-by-step explanation:
The area of a composite figure can be found by adding the areas of its parts.
__
Extending the vertical line across the figure cuts off a rectangle on the left that is 18 ft long and 10 ft high. It cuts off a triangle on the right that has a base of 20 ft and a height of 24-18 = 6 ft.
The sum of the areas of these parts is ...
rectangle area + triangle area
= (10 ft)(18 ft) +1/2(20 ft)(6 ft) = 180 ft² +60 ft²
= 240 ft² . . . . area of the figure
_____
Additional comment
You can see that this is the product of the height of the rectangle and the overall length of the figure. This means the smaller triangles that stick above or below the horizontal lines would fit exactly into the spaces at the tip of the arrow, filling in a 10 ft × 24 ft rectangle.

A package of 5 pairs of insulated gloves costs $43.95. What is the unit price of the pairs of gloves?
Answers
Answer:
5.89 dollars
Step-by-step explanation:
To find the unit price, we use t/q where t is the total price and q is the quantity.
Therefore, it costs 5.89 dollars for a pair of gloves.
The unit price of the pair of gloves will be $8.79 for each pair of gloves.
What is the rate?The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
A package of 5 pairs of insulated gloves costs $43.95. Then the unit price of the pairs of gloves is calculated as,
Rate = $43.95 / 5
Rate = $8.79 for each pair of gloves
The unit price of the pair of gloves will be $8.79 for each pair of gloves.

You lose track of how many 2-point baskets and 3-point baskets a team makes in a basketball game. The team misses all the 1-point baskets and still scores 54 points. The equation 2x+3y=54$ models the total points scored, where x is the number of 2-point baskets made and y is the number of 3-point baskets made. a. Find and interpret the intercepts.
Answers
Answer:
x-intercept: 27, the number of 2-pointers if no 3-pointersy-intercept: 18, the number of 3-pointers if no 2-pointersStep-by-step explanation:
Each intercept is found by setting the other variable to zero and solving for the variable value of interest.
2x +3y = 54
x-intercept:
2x = 54
x = 27
y-intercept:
3y = 54
y = 18
__
By definition, the intercept values are the values that satisfy the equation when the other variable is zero.
x-intercept: To score 54 points, the team would have to make 27 2-point baskets if no 3-point baskets were made.
y-intercept: To score 54 points, the team would have to make 18 3-point baskets if no 2-point baskets were made.
