I would like you to help me please.

Answer:

C. -3

Step-by-step explanation:

You can do this using two different methods.

First, slope is written rise over run, or y over x. We can find two points and count how much we need to rise and run. The graph already includes the points (2,-3) and (-1, 6), which we will use. If you carefully look at the graph, you can see that if you start from the point (2,-3), you can rise 9 and run -3 to get to the point (-1, 6), which brings me to the next step. As I stated in the beginning, slope is written rise over run. Therefore, the slope is 9/-3, which simplifies to -3, answer choice C.

Another way you can do this is subtracting the y's and subtracting the x's in the same order. The y's go over the x's, and is basically written as a fraction. For this method, we still need two points. We will use the same points as above and listed on the graph, points (2,-3) and (-1, 6). The y's are -3 and 6, and the x's are 2 and -1. Now, subtract.

-3-6  =-9=-3

2-(-1)= 3

As you can tell, both methods of solving for slope worked, and the answer is choice C.

I hope this helps you!! Have a great day ^^

Answer:

Step-by-step explanation:

The answer is -3

i just took the quiz and got it right

The rate of change for the given data is -3. Therefore, option A is the correct answer.

The coordinates from the given data are (-1, 5) and (2, -4).

The rate of change, or the slope, is calculated as Δy/Δx , or (y2−y1)/(x2−x1). The slope-intercept equation of a line is y=mx+b , where m is the slope and b is the initial value.

Here, (x1, y1)=(-1, 5) and (x2, y2)=(2,-4)

Rate of change = (-4-5)/(2+1)

= -9/3

= -3

The rate of change for the given data is -3. Therefore, option A is the correct answer.

Answer:

b<-7 or b>-1

Step-by-step explanation:

explanation: -6b>42 turns into -42>6b then divide by 6 on both sides and you get -7>b

for the other inequality, you  take 4b+6>2 and then subtract6 from both sides, from there you will get 4b>-4 and that will be b>-1

Answer:

[tex]\approx \frac{11}{40}[/tex]

Step-by-step explanation:

Juice squeezed from first orange = [tex]\frac{4}{17}[/tex] = 0.235

Juice squeezed from second orange = [tex]\frac{3}{10}[/tex] = 0.3

Juice squeezed from third orange = [tex]\frac{9}{20}[/tex] = 0.45

Juice squeezed from fourth orange = [tex]\frac{3}{11}[/tex] = 0.27

Juice squeezed from fifth orange = [tex]\frac{7}{15}[/tex] = 0.47

Total juice squeezed from all the five oranges = 0.235 + 0.3 + 0.45 + 0.27 + 0.47 = 1.725

Total juice to be squeezed = 2 cups

More juice required = 2 - 1.725 = 0.275 [tex]\approx \frac{11}{40}[/tex]

Therefore, to make it 2 cups of orange juice for the family, about [tex]\approx \frac{11}{40}[/tex] cups of more juice is required.

Answer:

x = 19

Step-by-step explanation:

(5x + 2)° + 83° = 180°

✍️Reason: both are linear pair angles. Linear pair angles are supplementary.

Solve for x

5x + 2 + 83 = 180

5x + 85 = 180

Subtract 85 from both sides

5x = 180 - 85

5x = 95

Divide both sides by 5

x = 95/5

x = 19

Answer:

Hai is incorrect, there is no solution to this equation.

Step-by-step explanation:

1.) Expand.

3x-4=2x+6+x3x−4=2x+6+x

2.) Simplify  2x+6+x2x+6+x  to  3x+63x+6.

3x-4=3x+63x−4=3x+6

3.) Cancel 3x3x on both sides.

-4=6−4=6

4.) Since -4=6−4=6 is false, there is no solution.

Therefore, this equation has no solution

Answer: 4

Step-by-step explanation:

Given: Total girls = 24

Total boys = 20

If each group must be identical, then the maximum number of groups that can be made = GCD(24,20)   [GCD= Greatest common divisor]

Since 24 = 2 x 2 x 2 x 3

20 = 2 x 2 x 5

GCD(24,20)= 2 x 2 = 4

Hence, the maximum number of groups that can be made = 4

Missing Part of the Question:

- The time required for the rocket to reach its maximum height

- The maximum height of the rocket

Answer:

a. Time to reach maximum height is 1.37 seconds

b. Maximum Height = 34.1 metres

Step-by-step explanation:

Given.

H(t) = -4.9t² + 13.4t + 24.9

Solving (a): Time taken to reach maximum height.

A quadratic equation is:

f(x) = ax² + bx + c

Where

a = -4.9

b = 13.4

c = 24.9

This required time is represented by the vertex and is calculated as thus:

t = -b/2a

Substitute values for b and a

t = (-13.4)/(2 * -4.9)

t = -13.4/(-9.8)

t = 13.4/9.8

t = 1.37 (approximated)

Hence the time to reach maximum height is 1.37 seconds

b. Maximum height

Here, we simply substitute 1.37 for t in

H(t) = -4.9t²+ 13.4t + 24.9

Maximum Height = -4.9 * 1.37² + 13.4 * 1.37 + 24.9

Maximum Height = -4.9 * 1.8769 + 13.4 * 1.37 + 24.9

Maximum Height = -9.19681 + 18.358 + 24.9

Maximum Height = 34.06119

Maximum Height = 34.1 metres (approximated)

C) [tex]x+y=20[/tex], [tex]3x+2y = 50[/tex]

D) [tex]x=10, y=10[/tex]

E) Yes, the result satisfies the equations.

Step-by-step explanation:

Let number of kilos of mango bought = [tex]x[/tex]

Let number of kilos of atis bought = [tex]y[/tex]

Total number of kilos bought = 20

A) [tex]x+y=20[/tex]

Cost of mango per kg = 60

Cost of mango for [tex]x[/tex] kg = [tex]60x[/tex]

Cost of atis per kg = 40

Cost of mango for [tex]y[/tex] kg = [tex]40y[/tex]

Total cost is: Cost of mango + Cost of atis = 1000

B) Cost function is:

[tex]60x+40y=1000\\\Rightarrow 3x+2y = 50 ...... (2)[/tex]

C) System of equations are:

[tex]x+y=20[/tex] ...... (1)

[tex]3x+2y = 50[/tex]...... (2)

D) Using elimination method:

Multiplying equation (1) with 2 and subtracting from (2):

[tex]x = 10[/tex]

By equation (1):

[tex]\Rightarrow y =10[/tex]

E) Putting both the values in LHS of equation (1):

10+10  = 20 = RHS

Putting both the values in LHS of equation (2):

[tex]3\times 10 +2\times 10[/tex] = 50 = RHS

Yes, the result satisfies the equations.

Answer:

What is it?

Step-by-step explanation:

Answer:

Step-by-step explanation:

The number of years between 1996 to 2002 will be:

= 2002 - 1996

= 6 years

The relationship relating the value of the card y in dollars and the number of years x the player has been in retirement can be expressed as an equation in the form of:

y = 5.71 + 1.98x

where x = 6 years

y = 5.71 + 1.98(6)

y = 5.71 + 11.88

y = $17.59

The value of the card in 2002 ​is $17.59.

The relationship between x and y isn't proportional in this case.

Answer:

trumpeter swans = t = 41

sand-hill cranes = s = 26

chickadees = c = 164

dusky grouses = d = 82

Step-by-step explanation:

Total birds = 313

Let

trumpeter swans = t

sand-hill cranes = s

chickadees = c

dusky grouses = d

t = 15 + s

c = 2d

d = 2t

t + s + c + d = 313

(15+s) + s + 2d + d = 313

15 + s + s + 2(2t) + 2t = 313

15 + 2s + 4t + 2(15+s) = 313

15 + 2s + 4(15 + s) + 30 + 2s = 313

15 + 2s + 60 + 4s + 30 + 2s = 313

105 + 8s = 313

8s = 313 - 105

8s = 208

s = 208 / 8

= 26

s = 26

t = 15 + s

= 15 + 26

= 41

d = 2t

d = 2(41)

= 82

c = 2d

c = 2(82)

= 164

trumpeter swans = t = 41

sand-hill cranes = s = 26

chickadees = c = 164

dusky grouses = d = 82

Answer:

29.7

Step-by-step explanation:

y = 2.7x + 2.7

y = 2.7(1) + 2.7 = 5.4

y = 2.7(2) + 2.7 = 5.4 + 2.7 = 8.1

y = 2.7(3) + 2.7 = 8.1 + 2.7 = 10.8

y = 2.7(4) + 2.7 = 10.8 + 2.7 = 13.5

y = 2.7(10) + 2.7 = 27 + 2.7 = 29.7
