Which value of y makes the inequality 3y^2 +2(y-5)>8 true?
Answer: D
Step-by-step explanation:
A) 3*0^2+2(0-5)>8
-10>8 -> not true
B) 3*(-1)^2+2(-1-5)>8
3*1+2*(-6)>8
3- 12>8
-9> 8 -> not true
C) 3*(-2)^2+2(-2-5)>8
3*4+2*(-7)>8
12-14>8
-2> 8 -> not true
D) ) 3*(-3)^2+2(-3-5)>8
3*9+2*(-8)>8
27-16>8
11> 8 -> true

evaluate -6(7/6)+2(1/3)=
-6.333333... OR -19/3
In the problem: -6(7/6) + 2(1/3) Let's only worry about the left of the equal sign for now.
-6(7/6) we have to simplify this. So what we do is we multiply -6(7) and leave the denominator the same so -6(7/6) is -7.
Now we simplify the right part of this problem.
2(1/3) just like the 1st time, we have to simplify this. So what we do is we multiply 2 and 1 together and leave the denominator the same. So, 2(1) is 2 and leave the denominator the same so the answer is 2/3
Now add them together.
-7 + 2/3 = 6.333...
If you are driving 30 miles per hour, how far will you go in 5 hours? To solve this problem, all you need to do is multiply your rate by 5. Remember to multiply both the numerator and denominator by the same number.
30 miles/1 hour × 5/5 = 150 miles/5 hours.
You will drive 150 miles in 5 hours. Don’t forget to label your answer with the correct units!

A company paid $ 391 for 15 bushes and 8 bonsai trees . They had to purchase 9 more bushes and 5 more bonsai trees for $ 241 . What is the cost of each bush and bonsai tree ? the boxes below .
Answer:
Cost of one bush = x = $9
Cost of one bonsai tree = y = $32
Step-by-step explanation:
Let Cost of one bush = x
Cost of one bonsai tree = y
From the expression: A company paid $ 391 for 15 bushes and 8 bonsai trees
We made equation: [tex]15x+8y=391[/tex]
and From the expression: They had to purchase 9 more bushes and 5 more bonsai trees for $ 241 , we made equation: [tex]9x+5y=241[/tex]
Solving both equations simultaneously we can find value of x and y
Let:
[tex]15x+8y=391--eq(1)\\9x+5y=241--eq(2)[/tex]
We will use elimination method to solve these equations.
Multiply eq(1) by 5 and eq(2) by 8 and subtract
[tex]75x+49y=1955\\72x+40y=1928\\- \ \ \ - \ \ \ \ \ \ \ -\\--------\\3x=27\\x=\frac{27}{3}\\x=9[/tex]
So, value of x=9
Now finding value of y by putting value of x in equation 1
[tex]15x+8y=391\\Put \ x=9\\15(9)+8y=391\\135+8y=391\\8y=391-135\\8y=256\\y=\frac{256}{8}\\y=32[/tex]
So, value of y=32
Cost of one bush = x = $9
Cost of one bonsai tree = y = $32
33 + 19 - 11 + 26t2 - +2
33+19 -11 + 26t X 2 - 2 =52t + 39.

Select the correct answer. A sound wave enters a new medium where sound travels faster. How does this affect the frequency and wavelength of the sound? A. The frequency increases and the wavelength decreases. B. The frequency decreases and the wavelength increases. C. The frequency stays the same and the wavelength increases. D. The frequency stays the same and the wavelength decreases. E. Neither the frequency nor the wavelength is affected.
Answer:
The correct answer is E. Neither the frequency nor the wavelength is affected. Explanation: The wave frequency does not affect the speed of that wave. An increase in frequency of a wave causes a decrease in wavelength while the wave speed remains the constant. The speed of the waves is significantly higher at higher tensions.

The graph models the value of an automobile over a 7 year period of time.
Which equation best represents the relationship between x, the age of the automobile in years, and y, the value of the automobile in dollars
Answer:
y=-500x+22,000
Step-by-step explanation:
It's this one because the 22,000 shows the initial value of the automobile and -500x is how much value the automobile loses per year.
Answer:
Y = mx + c
C = 22,000
But slope is unknown
Y= mx + 22000

A band is playing at an auditorium with floor seats and balcony seats. The band wants to sell the floor tickets for $15 each and balcony tickets for $12 each. They want to make at least $3,000 in ticket sales.
what i got -
15x + 12y ≥ 3000
how i got it -
Number of floor seats tickets sold = x
Number of balcony seats tickets sold = y
Cost of floor tickets = $15
Cost of balcony tickets = $12
They want to make at least $3,000 in ticket sales.
At least in inequality means ≥
The inequality that represent the situation is 15x + 12y ≥ 3000
