Answer:
−8<r≤3
Step-by-step explanation:
The final inequality of 24>−3r≥−9 is -8 < r ≤ 3.
Given,
24>−3r≥−9
We need to solve this inequality.
What are inequalities?We have,
< = less than
> = greater than
≤ = less than and equal
≥ - greater than and equal
If we change the sign we change the inequality.
Example:
2 > -1
Multiply -1 on both sides.
-2 < 1
We have,
24 > -3r ≥ -9
We can cancel the common factor.
3 x 8 > -3r ≥ - 3 x 3
8 > -r ≥ -3
Multiply - on all sides.
-8 < -(-r) ≤ -(-3)
-8 < r ≤ 3
This means r values are between -8 and 3.
r = ( -8, 3]
Thus the final inequality of 24>−3r≥−9 is -8 < r ≤ 3.

BRAINLIEST ANSWER!! NEED HELP ASAP!
Answer:
1. 30(8.75) + 11t = 400
2. 12.5 hours
Step-by-step explanation:
1. What is given is you work for 30 hours per week at a gas station for $8.75 an hour. You also work as a landscaper for $11 an hour. You want to a make a total of $400 per week.
30 hours and $8.75 an hour would be equivalent to 30(8.75)
We don’t know how many hours you work as a landscaper but you earn $11 an hour, which is equivalent to 11t
Finally, you want to earn a total of $400 a week, which means the sum equals 400
30(8.75) + 11t = 400
2. 30(8.75) = 262.5
400 - 262.5 = 137.5
137.5 / 11 = 12.5

Answer:
y= 1/2 is the answer.
Step-by-step explanation:
Answer:
y = 2
Step-by-step explanation:
Write the inverse function,
f^-1 (x), for the function
f (x) = 1/3x-4
[tex]f(x) = \frac{1}{3}x - 4 \\ [/tex]
[tex]y = \frac{1}{3}x - 4 \\ [/tex]
Subtract the sides of the equation plus 4
[tex]y + 4 = \frac{1}{3}x \\ [/tex]
Multiply the sides of the equation by 3
[tex]3(y + 4) = x[/tex]
[tex]3y + 12 = x[/tex]
So ;
[tex] {f}^{ - 1}(x) = 3x + 12 [/tex]

A boat travels upstream on the Mississippi river for 3.5 hours. The return trip only takes 2.5 hours because the boat travels 2 miles per hour faster downstream due to the current. How far does the boat travel upstream? Which is the best equation to use?
Answer:
17.5 miles per hour
Step-by-step explanation:
A boat travels upstream on a Mississippi river for 3.5 hours
The return trip takes 2.5 hours
The boat travels 2 miles per hour faster downstream
Let y represent the speed that was travelled upsteam
3.5y = 2.5(y + 2)
3.5y = 2.5y + 5
3.5y - 2.5y = 5
y = 5
Therefore the distance travelled by the boat upstream can be calculated as follows
= 3.5 × 5
= 17.5 miles per hour

Write the quadratic equation whose roots are 1 and 5, and whose leading coefficient is 2.
Answer:
[tex]\Large \boxed{\sf \bf 2x^2-12x+10}[/tex]
Step-by-step explanation:
Hello,
As 1 and 5 are roots we can write, with a real number, the quadratic equation as
a(x-1)(x-5)
and as the leading coefficient is 2 then a = 2
It comes
[tex]2(x-1)(x-5)=2(x^2-6x+5)=2x^2-12x+10[/tex]

The quadratic equation will be 2x²-12x+1=0.
What is a quadratic equation?Quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
Given that the roots of the quadratic equation are 1 and 5 and the leading coefficient is 2.
The equation will be written as,
Quadratic equation = 2( x - 1 ) ( x - 1 )
Quadratic equation = 2 ( x² + 4x - 5)
Quadratic equation = 2x² + 8x - 10
Therefore, the quadratic equation will be 2x²-12x+1=0.

find x and measure ABC
pls help I’ve been trying this for 30 minutes.
Geometry
[tex](2x - 9) + (3x - 6) = 110[/tex]
[tex]2x + 3x - 9 - 6 = 110[/tex]
[tex]5x - 15 = 110[/tex]
Plus sides 15
[tex]5x - 15 + 15 = 110 + 15[/tex]
[tex]5x = 125[/tex]
Divided sides by 5
[tex] \frac{5}{5}x = \frac{125}{5} \\ [/tex]
[tex]x = 25[/tex]
Thus ;
A = 2 ( 25 ) - 9°
A = 50° - 9°
A = 41°
_________________________________
B = 3 ( 25 ) - 6
B = 75° - 6°
B = 69°
_________________________________
C + 110° = 180°
because it is a straight line.
Subtract sides 110°
C + 110° - 110° = 180° - 110°
C = 70°

Answer:
k=45
Step-by-step explanation:
Since the sum of the measures are 180 and the measures are 45 degrees, k degrees, and 2k degrees, we can conclude that [tex]45+2k+k=180[/tex]. 2k and k are like terms, so you can add 2k and k to get 3k.Then, you would have [tex]45+3k=180[/tex]. Since you are finding k, you want to isolate k as best you can. To do this, you subtract 45 on both sides [tex]45-45+3k=180 -45 \\3k=135[/tex] as shown by the equation, 180-45 is 135. Then, you divide 3 on both sides to get k=45.
