Given the function f(x) = –22 – 7x + 18, determine the average rate of change
of the function over the interval -10 < x < -1.
Note: May be you meant to write the function as:
f(x)=-22x²-7x+18
Answer:
The Average rate of function = 235
Step-by-step explanation:
Given the function
f(x) = –22x² – 7x + 18
Interval = -10 < x < -1
so
taking x₁ = -9, x₂ = -2 in the interval
f(x₁) = f(-9) = -22(-9)² – 7(-9) + 18
= -1701
f(x₂) = f(-2) = -22(-2)² – 7(-2) + 18
= -56
Using the formula
Average rate of change = f(x₂) - f(x₁) / x₂-x₁
= (-56) - (-1701) / (-2) - (-9)
= (-56 + 1701) / (-2+9)
= 1645 / 7
= 235
Thus, the Average rate of function = 235

Luis and olivia are saving money to buy their favorite candy at the store. For every $5 Luis saves, Olivia saves $7. After a week, Luis saves $42 less than Olivia. If there favorite candy cost $2.50 per pack, how many packs of candy can each of them buy
Given :
Luis and Olivia are saving money to buy their favorite candy at the store.
For every $5 Luis saves, Olivia saves $7.
After a week, Luis saves $42 less than Olivia.
To Find :
If there favorite candy cost $2.50 per pack, how many packs of candy can each of them buy.
Solution :
Ratio of money saved by Olivia and Luis is 7/5 .
Let, money save by Olivia is x.
So, money saved by Luis is x - 42 .
[tex]\dfrac{7}{5}=\dfrac{x}{x-42}\\\\7x - 294 = 5x\\\\x =\$ 147[/tex]
Money saved by Luis, $105 .
Number of pack Olivia can buy is, = 147/2.5 = 58.8 = 58 packets.
Number of pack Luis can buy is, = 105/2.5 = 42 packets.
Therefore, Olivia and Luis can buy 58 and 42 packets respectively.

5x+4y=2
3x+3y=-3
IM LITERALLY BEGGING FORN HELP RN
Answer:
x = 6, y = -7 or (6, -7)Step-by-step explanation:
Given system of equations
5x+4y=2 3x+3y=-3Solving as follows:
Simplify the second equation by dividing all terms by 3
3x+3y=-3 divide by 3⇒ x + y = -1Now, considering the coefficient of x of 5 in the first equation, we will multiply the simplified second equation by 5 and subtract from the first equation:
x + y = -1 multiply by 5⇒5x + 5y = -5Subtract it from 5x + 4y = 2
5x + 4y - 5x - 5y = 2 - (-5)-y = 7y = -7Finding x using simplified second equation:
x + (-7) = -1x = - 1 + 7x = 6Answer is (6, -7)

A gardening center has 1,582 pots to fill. Each bag of soil can fill 4 pots. How many bags of soil are needed?
Answer:
395.5 bags of soil
Step-by-step explanation:
1582 pots in the gardening center will need 396 bags of soil to fill them.
What is unitary method?The unitary method is a process of finding the value of a single unit and using this value we can find the value of the required number of units.
Given is a gardening center that has 1,582 pots to fill. Each bag of soil can fill 4 pots.
Number of pots to filled = n[f] = 1582
Number of pots fille by 1 bag of soil = n[s] = 4
Now, 4 pots need 1 bag of soil. So 1 pot will need (1/4) bag of soil. Therefore, 1582 pots will need → (1/4) x 1582 which his equivalent to 395.5 or 396 bags (approximately).
Therefore, 1582 pots will need 396 bags of soil to fill them.

5) x - 4y = 28
-4x - y = 7
Solve each system by elimination
Answer:
x = 0, y = -7
Step-by-step explanation:
x - 4y = 28
-4x - y = 7
____________
x - 4y = 28
-16x - 4y = 28
____________ _
17x = 0
x = 0
0 - 4y = 28
y = -7
Answer:
(0,-7)
Step-by-step explanation:
x-4y=28 multiply by 4
-4x-y=7 multiply by 1
4x-16y=112
-4x-y=7
cross out the x and add the rest
-17y= 119
divide by -17
y= -7
now you substitute the y in one of the equations.
the reformed equations
we will use the second one
-4x-(-7)=7
two negative becomes a plus
-4x+7=7
now you minus the 7 to both sides
-4x=0
now divide by -4
x=0

A car is traveling at a steady speed. It travels 2 1/3 miles in 3 1/2 minutes. How far will it travel in 38 minutes In 1 hour
Answer:
a) distance traveled is 16 miles.
b) distance traveled is 40 miles.
Step-by-step explanation:
Speed is a scalar quantity which describe the rate of distance moved with time.
i.e speed =
Given that: distance = 2 1/3 miles = miles, time = 3 1/2 minutes = minutes.
Then;
speed = ÷
= x
=
The car's steady speed is 0.67 miles per minute.
a) when the time is 24 minutes, the distance covered can be determine by:
distance = speed x time
= x 24
= 16
distance traveled is 16 miles.
b) When the time is 1 hour (60 minutes), the distance traveled can be determined by:
distance = speed x time
= x 60
= 40
distance traveled is 40 miles.
