Solve for x: 5<-4x-11<13
Answer:
[tex] - {4} < x < - 6 \\ [/tex]
Step-by-step explanation:
[tex]5 < - 4x - 11 < 13[/tex]
Add 11 to both sides of the inequality to make - 4x stand alone
[tex]5 + 11 < - 4x - 11 + 11 < 13 + 11 \\ 16 < - 4x < 24[/tex]
Divide both sides by - 4
[tex] - \frac{16}{4} < \frac{ - 4x}{ - 4} < - \frac{24}{4} \\ - {4} < x < - 6[/tex]
Reverse the signs
We have the final answer as
[tex] - 4 > x > - 6 \\ [/tex]

I REALLY NEED HELP PLS!!! Devon earned $42,500 last year and spent 12% of it on home repairs. How much did he spend on his home?
Answer:
$47,600 Spent on home repairs
Step-by-step explanation:
So we know that Devon is spending 12 percent of the home cost on repairs
We know the home cost is 42,500
So we just add 12 percent to the bundle
We know 42,500 is 100 percent of the price
And we want to add another 12 percent since the question is asking for the total amount spent on homes
So initially we just multiply 42,500 by 112% or 1.12
Now just multiply
You’ll get 47,600
A car drives 195 miles in 3 hours and 15 minuits. What is the average speed of the car?
Answer: [tex]61.9miles/hr[/tex]
Step-by-step explanation:
given data:
distance travelled by the car = 195 miles
time taken = 3 hours and 15mins
solution
average speed of the car
[tex]= \frac{195miles}{3hrs15mins} \\\\= 61.9miles/hr[/tex]
Answer:
The average speed is [tex]v=60 miles/h[/tex]
Step-by-step explanation:
The equation of the average speed os given by:
[tex]v=\frac{\Delta x}{\Delta t}[/tex] (1)
here:
Δx is just 195 miles
Δt is the time traveled. 3.25 h ( 3 h + 15 min or 0.25 h)
So we just need to put this into the equation (1)
[tex]v=\frac{195}{3.25}[/tex]
Therefore, the average speed is [tex]v=60 miles/h[/tex]

You buy pounds of trail mix. The mix costs $ per pound. What is the total price for the trail mix?
Complete question :
You buy 3.9 pounds of trail mix. The mix costs $2.99 per pound. What is the total price for the trail mix?
Answer:
$11.661
Step-by-step explanation:
Given that :
Cost per pound of trail mix = $2.99
Pounds of trail mix purchased = 3.9 pounds
Total price of the trail mix :
(Cost per pound of trail mix * pounds of trail mix purchased)
($2.99 * 3.9 pounds)
= $11.661

Find the measure of the exterior angle.
Jamal and Samuel are saving for a camping trip. Jamal starts with $18 and saves $5 each week. Samuel starts with $10 and saves $7 each week. Use the drop-down menus to complete the rule for the amount of savings for each boy.
Answer:
4 weeks
$28
Step-by-step explanation:
Let
x = number of weeks
Jamal's savings = 18 + 5x
Samuel's savings = 10 + 7x
Equate both savings
Jamal's savings = Samuel's savings
18 + 5x = 10 + 7x
18 - 10 = 7x - 5x
8 = 2x
x = 8 / 2
= 4
x = 4 weeks
Check:
18 + 5x
18 + 5(2)
18 + 10
= $28
Each boy would have saved an equal amount of $28 at the end of the 4th week

2m - 4
Question: +6 charge and -6 charge
Question 2: 8 units to the left of 4
(4 - 8 = -4 and 8 units left is -4)
Question 3: 4
(7 +(-3) is essentially 7-3 which equals 4 because negative takes over the positive)
Question 5: 1/-6
(it doesn't matter if the negative symbol is on top or bottom, numerator or denominator just the numbers have to stay in the same place)
Question 4: -45
(4.5 times 5 is 22.5, and 22.5 times -2 is -45, the negative takes over the positive)
Question 6: 2m-4
( 2(m-5) +6
distribute first
2 times m = 2m
2 times -5 = -10
so now you have 2m - 10 + 6
combine like terms to get 2m - 4
(-10 + 6 = -4)

The graph of f(x) = 4x3 – 13x2 + 9x + 2 is shown below.
On a coordinate plane, a function is shown. The function starts from the bottom of quadrant 3 and goes up through the x-axis at (0, negative 0.25) and then through the y-axis at (0, 2). It then starts to curve down at (0.5, 4) until it reaches (1.75, negative 0.5). It then curves up and crosses the x-axis at (2, 0) and goes up approaching x = 3.
How many roots of f(x) are rational numbers?
0
1
2
3
Answer:
3
Step-by-step explanation:
f(x) = 4x^3 – 13x^2 + 9x + 2
This looks complicated but all we need to find are the Roots
We are looking for when y=0
So given each part of the information, we can label how many times it happens
The function starts from the bottom of quadrant 3: Starts lower left
and goes up through the x-axis at (0, negative 0.25) : This is ONE ROOT
and then through the y-axis at (0, 2). : It's now on the 2nd quartile
It then starts to curve down at (0.5, 4): It's moving towards y=0
until it reaches (1.75, negative 0.5).: It has now passed y=o and there are TWO ROOTS
It then curves up and crosses the x-axis at (2, 0) and goes up approaching x = 3: It has passed y=0 again, so there are THREE ROOTS
This polynomial function has 3 ROOTS

1) In a bag of red and green sweets, the ratio of red sweets to green sweets is 3:7. If the bag contains 49 green sweets, how many red sweets are there?
Answer:
Red sweets = 21
Step-by-step explanation:
Let there are 3x red sweets and 7x green sweets.
Total no of 49 green sweets.
ATQ,
7x = 49
x = 7
Red sweets = 3x
= 3(7)
= 21
Hence, there are 21 red sweets.

Problem:
Store A has the bat originally priced at $245 and is having a 25% off sale.
Store B’s bat has an original price of $166 but is marked up 20%.
Which store has the better price for the baseball bat
Answer:
Store A has a better deal
Step-by-step explanation:
Store A-
245x.25=61.25
245-61.25=183.75
Store A's sale price is $183.75
Store B-
166x.20=33.20
166+33.20= 199.20
Store B's new price is $199.20
Conclusion
$183.75 is less than $199.20 so store A has a better deal because you're paying less than what you would be paying at store B
What is the slope of the line? *
Answer:
- 1.5
Step-by-step explanation:
I suggest to make a table
x y
-2 3
2 -3
from 3 to -3, you subtract 6
from -2 to 2, you add 4
so y/x
-6/4 = -1.5
Slope is -1.5
