evaluate the piecewise function
Answer:
f(-7) = -6
f(10) = 9
Step-by-step explanation:
Because -7 is less than 0 you can use the top equation -7 + 1 to get 6
Because 10 is greater than 0 you can use the bottom equation 10 - 1 to get 9

Answer:
x = 23
Step-by-step explanation:
Eliminate parentheses, separate the variables and the constants, divide by the coefficient of the variable.
7(x +4) = 9(x -2) . . . . . given
7x +28 = 9x -18 . . . . . eliminate parentheses using the distributive property
28 = 2x -18 . . . . . . . . . subtract 7x*
46 = 2x . . . . . . . . . . . . add 18
23 = x . . . . . . . . . . . . . divide by 2
The solution is x = 23.
Check
7(23+4) = 9(23-2) ⇒ 7·27 = 9·21 . . . true (=189)
__
* We choose to subtract 7x instead of 9x so that the resulting x-term has a positive coefficient.

Additional comments
The properties of equality tell you that you can do anything you like to an equation, as long as you do the same thing to both sides of the equation. So, when we say "subtract 7x", we mean that value is subtracted from both sides of the equation. Subtracting a value, or adding its opposite, is a way to remove a term from a place in the equation where you don't want it.
Here, the smaller x-coefficient is on the left, so we choose that term to subtract. That leaves the remaining x-term on the right (with a positive coefficient). We don't want any constants there, so we add the opposite of that constant. (The opposite of -18 is 18, so that is what we add--to both sides.)

Sometimes you will be told differently. You will be told to "put that over there and change its sign" or "cross-multiply". These instructions are based on appearance. The fundamental, always-applicable rule is "do the same thing to both sides of the equation." With practice and understanding, you can begin to think in terms of these shortcut suggestions.
Which of the functions below is a linear function? y=x-7 y= 1 / - 7 y=x² - 7 y=1x1-7
Answer:
y=x-7
Step-by-step explanation:
the rest are squared which means that they are parabolas. The last one has multiplication.
Give 1 other example where quadratics (parabolas) might
be used by a career?
Answer:
Agriculture
Step-by-step explanation:
Quadratic equations are also used in agriculture. One of these uses is in finding out the optimal arrangement of boundaries to produce the biggest fields and pens given the materials on hand. Area is the length of a surface multiplied by its width. This turns calculations involving areas into quadratic equations.

Does this show a function please explain
Answer:
where is the dot, I Bileve it is no.
Solve for x
Please show the steps
The answer is 10
Answer:
x = 10
Step-by-step explanation:
Since ΔCDE ~ ΔQRS, we can find the actual length of x + 8 first before finding the value of x.
Length of x + 8 = [tex]\frac{12}{20}[/tex] × 30
= 18
x + 8 = 18
x = 18 - 8
x = 10
You are planning a skating party at a rink that charges a basic fee of
$10.00 and $6.00 per person for catered parties. You don't want to spend
more than $52.00. Write and solve an inequality to find the number of
friends you can invite.
a. 6x + 10 < 52; x< 7
6. 6x + 10 > 52; <> 7
C. 6% + 10 > 52; 2 >7
d. 6x + 10 < 52; x < 7
Answer:
y = 6.50x + 6 or 71 = 6.50x + 6
10 people are the max you can invite
Step-by-step explanation:
We have the simple equation
y = 6.50x + 6
6.50x because it it per person
6 because it is a flat one time charge
We want the max to be 71 so that will be our y
71 = 6.50x + 6
We are now going to solve for x
65 = 6.5x
x = 10

Michael is buying a new pair of headphones from an electronics store. The headphones cost $15.50, but Michael has a coupon that will reduce the cost by $4.00. He must pay 6% sales tax on the discounted price of the headphones. How much will Michael pay in total for the headphones, including tax?
Answer: Michael pays $12.19 for the headphones including the tax.
Step-by-step explanation:
The initial price of the headphones was $15.50
When Michael uses his coupon, the price is decreased by $4, then the new price will be:
$15.50 - $4 = $11.50
Now Michael must pay 6% for taxes (on the discounted price), then he must pay:
$11.50 + (6%/100%)*$11.50
$11.50 + 0.06*$11.50
$11.50*1.06 = $12.19
Then Michael pays $12.19 for the headphones including tax.

From 20 tons to 99 tons? Increase or decrease?
Answer:
increase in weight
Step-by-step explanation:
Answer:
Increase.
Step-by-step explanation:
20 is larger than 99. if one ton is 2000 pounds then 20 tons are 40,000 pounds. So 99 times 2000 is 198,000 pounds, which is larger than 40,000.
Summary: 20 tons (40,000 pounds) < 99 tons (198,000) pounds
