Answer:

A = -17

Step-by-step explanation:

F(5) = -4(5) + 3

F(5) = -20 + 3

F(5) = -17

Answer:

D. 23

Step-by-step explanation:

f(-5) = -4(-5) + 3

= 20 + 3

= 23

therefore f(-5) is 23

Answer:

x=20

Step-by-step explanation:

pentagon= 3 triangles could be made-> 3 x 180

total angle = 540

540= 5x+2+5x+10+4x+15+8x+8+3x+5

540=25x+40

500=25x

20=x

Answer:

Okay so this is the best way to explain it, its already in y=mx+b form which is the easiest way to graph something, its where m= slope and b=the y-intercept  so 1/3 is m so the slope is 1/3 but first we need to mark the y coordinate which is 5, so on your graph dot (0,5) then from that go up 1 and right 3 then that should be your graph!!! I've included pictures to help you know what it should look like.

Step-by-step explanation:

Please look at pictures below!! This is the best explanation i could give, Hope this helps!!!

Answer: $335,633

Step-by-step explanation:

First find the number of years difference:

= 2025 - 1985

= 40 years

Use the compound interest formula to find the answer:

= Value * ( 1 + rate) ^ no. of years

= 125,000 * ( 1 + 2.5%)⁴⁰

= $335,633

Answer:

As "x" increases "y" *decreases*

y as a function of x is not *constant*

Therefore the function is *nonlinear*

For all values of x, the function value y *≥* 0.

The y intercept of the graph is *8*

x=1 function value of y is *5*

Answer:

Step-by-step explanation:

[tex]-8=-\frac32z[/tex]         {swap sides}

[tex]-\frac32z=-8[/tex]         {divide both sides by (-³/₂)}

[tex]z=-8\div(-\frac32)\\\\z=-8\times(-\frac23)\\\\z=-\frac{16}3=-5\frac13[/tex]

Answer:

194527.41792

Step-by-step explanation:

Volume for each rod: 1130.97336

Multiply the volume by 172:

1130.97336 x 172 = 194527.41792

And that's your answer

Answer:

Cost of Material per square foot = $1.7

Step-by-step explanation:

Given:

Length = 24

Width = 12

Height = 6.5

Find:

Cost of Material per square foot

Computation:

TSA of pit = 2[bh + hl] + lb

TSA of pit = 2[(12)(6.5) + (24)(6.5)] + (24)(12)

TSA of pit = 2[78+156] + 288

TSA of pit = 756 square foot

Cost of Material per square foot = 1,285.20 / 756

Cost of Material per square foot = $1.7

Answer:

8) x=9

10) 23 degrees

Step-by-step explanation:

8) vertical angles are congruent to each other so we can set the expressions as such and solve:

7x + 3 = 10x - 24

3 = 3x - 24

27 = 3x

9 = x

10) since the angles are complementary they equal 90 degrees, so we can set the expression like this and solve for x:

12x + 7 + 6x - 7 = 90

18x + 7 - 7 = 90

18x = 90

x = 5

now we plug it back into the expression equivalent to the measure of angle O:

6(5) -7

30 - 7

23 degrees

Answer:

The music director can make 15 groups of performers with 6 sixth grade students and 5 seventh grade students in each group.

Step-by-step explanation:

A school chorus has 90 sixth-grade students and 75 seventh-grade students.

Factor these two numbers:

Find GCF(90,75):

Now,

Therefore, the music director can make 15 groups of performers with 6 sixth grade students and 5 seventh grade students in each group.

Answer:

6 pounds

Step-by-step explanation:

Answer:

5 pounds

Step-by-step explanation:

12 divided by 3 = 4

20 divided by 4 = 5

Given:

The function is

[tex]f(x)=-2x^4-4x^3+x^2+x+3[/tex]

To find:

The graph of the function by using the end behaviors.

Solution:

We have,

[tex]f(x)=-2x^4-4x^3+x^2+x+3[/tex]

The degree of the polynomial is 4 which is even and the leading coefficient is -2, which is negative. So,

[tex]f(x)\to -\infty\text{ as }x\to -\infty[/tex]

[tex]f(x)\to -\infty\text{ as }x\to \infty[/tex]

It means, the graph of the function approaches to negative infinity on the both ends.

Therefore, the correct option is C.

Answer:

1.07 hours

Step-by-step explanation:

14 miles = 1 hour

15 miles = x hours

Equal these two together

14 mi/1hr = 15 mi/xhr

Cross multiply

14 mi × x hr = 1 hr × 15 mi

I will stop using the units for now so it won't be as confusing

14x = 15

Divide both sides by 14 to isolate the variable

14x ÷ 14 = 15 ÷ 14

x = 1.07... hours
