What is the slope of the line that passes through the points (-2,6) and (4,10)?

Answers

Answer:

The answer is

[tex] \huge \frac{2}{3} \\ [/tex]

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\ [/tex]

From the question we have

[tex]m = \frac{10 - 6}{4 - - 2} = \frac{4}{4 + 2} = \frac{4}{6} = \frac{2}{3} \\ [/tex]

We have the final answer as

[tex] \frac{2}{3} \\ [/tex]

Jeffrey and Frank walk at different speeds.Frank’s walking speed can be represented by the equation y=85x, where is the time in minutes and y is the distance in meters. The distance Jeffrey walked over the time is shown on the graph below

Answers

Answer:

Option (C)

Option (A)

Step-by-step explanation:

Part A.

Frank's walking speed can be represented by the equation.

Equation representing the speed is,

y = 85x

[tex]\frac{y}{x}=85[/tex]

Therefore, walking speed of Frank = 85 meters per minute.

Option (C) will be the answer.

Part B.

Distance walked over the time by Jeffrey is given by the graph attached.

Equation for the speed will be,

y = [tex](\frac{400}{5})x[/tex]

y = 80x

Therefore, walking speed of Jeffrey = 80 meters per minute

Difference in the speed of Frank and Jeffrey = 85 - 80 = 5 meters per minute.

Jeffery walks 5 meters per minute slower than Frank.

Option (C) will be the answer.

Part (C)

Distance traveled by Frank in 16 minutes,

y = 85(16) = 1360 meters

Time taken to travel the same distance by Jeffrey will be,

1360 = 80x

x = [tex]\frac{1360}{80}=17[/tex] meters per minute

Option (A) will be the answer.

the vertex for f(x)=-7(x+8)^2+ 3 is the minimum for that function ture or false

Answers

Answer:Do you what it in vertex because if you do the answer is (-8,3)

Step-by-step explanation:

Answer:

False

Step-by-step explanation:

The equation of a parabola in vertex form is

f(x) = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

f(x) = - 7(x + 8)² + 3 ← is in vertex form

with (h, k) = (- 8, 3 )

• If a > 0 then vertex is a minimum

• If a < 0 then vertex is a maximum

Here a = - 7 < 0 , thus

(- 8, 3 ) is a maximum

Divide 3/5 by 1/2 as a reduced fraction.

Answers

Answer:

You can't divide two fractions together, so you multiply the second fraction by taking its reciprocal.

[tex]\frac{3}{5} * \frac{2}{1} \\\\= \frac{6}{5}[/tex]

If we divide the [tex]\frac{3}{5}[/tex] by [tex]\frac{1}{2}[/tex] so the decrease fraction should be [tex]\frac{6}{5}[/tex].

Given that,

The fraction is [tex]\frac{3}{5}[/tex].And, the other fraction is [tex]\frac{1}{2}[/tex].Now it should be divided to come as a reduced fraction.

So, the decreased fraction should be

[tex]= \frac{3}{5} \times \frac{2}{1} \\\\= \frac{6}{5}[/tex]

Therefore we can conclude that if we divide the [tex]\frac{3}{5}[/tex] by [tex]\frac{1}{2}[/tex] so the decrease fraction should be [tex]\frac{6}{5}[/tex].

Triangle PQR with coordinates P(3,-4), (6, -1), and R(6, -6) is translated -3 units horizontally and 6 units vertically. What will
be the coordinates of P'Q'R'?

Answers

Answer:

(0, 2), (3, 5) and (3, 0)

Step-by-step explanation:

Since, Points P(3,-4), Q(6, -1), and R(6, -6) is translated -3 units horizontally and 6 units vertically.

Therefore,

P' (3 - 3, - 4 +6) = P' (0, 2)

Q'(6 - 3, - 1 + 6) = Q'(3, 5)

R'(6 - 3, -6 + 6) = R'(3, 0)

Thus, the coordinates of P'Q'R are (0, 2), (3, 5) and (3, 0).

Answer:

P'(0, 2), Q'(3, 5), R'(3, 0)

Step-by-step explanation:

Given

Points P(3,-4), Q(6, -1), R(6, -6) Translation: x -3, y + 6

New points:

P'(3 - 3, -4 + 6) = P'(0, 2)Q'(6 - 3, -1 + 6) = Q'(3, 5)R'(6 - 3, -6 + 6) = R'(3, 0)
