Ashley ran from home to school in 10 minutes. What is her average speed, if the distance between her house and her school is 1.5 miles?

Answer:

16

Step-by-step explanation:

To find the term needed, use the binomial formula.

[tex](a+b)^2 = a^2 + 2ab + b^2[/tex]

Let 8x = 2ab, a is by default x, which leaves us with:

8x = 2xb

8 = 2b

b = 4

And by the binomial formula add [tex]b^2[/tex] to both sides, namely 16.

[tex]x^2 + 8x + 16 = 17 + 16\\(x+4)^2 = 33[/tex]

The area is 10 :) hope that helps

Edit:

Reason:

(a+b)/2 * h is the formula plug in the numbers and you get:

(4+6)/2 * 2

10/2 * 2

5 * 2

= 10 feet.

Answer:

a. true: 3    false: -5

b. true: 9    false: 2

c. true: 1/3  false: 1

d. true: 2    false: 3

From the diagram, since[tex]$\angle AHK$[/tex]  and [tex]$\angle EHB$[/tex]  are supplementary angles, we have [tex]m\angle AHK + m\angle EHB = 180^\circ$.[/tex]

Substituting in the values that are given, we get [tex]48^\circ + (4x-2)^\circ = 180^\circ$.[/tex] Solving for x, we get [tex]$x = \boxed{33.5}$.[/tex]

From the diagram, we see that angles [tex]$\angle AHK$[/tex] and [tex]$\angle EHB$[/tex]  are supplementary angles.

Therefore, we have the equation [tex]m\angle AHK + m\angle EHB = 180^\circ$.[/tex]

Substituting in the values that are given, we get [tex]48^\circ + (4x-2)^\circ = 180^\circ$.[/tex]

Simplifying both sides of the equation, we get [tex]4x-2 + 48 = 180$.[/tex]

Subtracting 46 from both sides of the equation, we get [tex]4x = 134$.[/tex]

Dividing both sides of the equation by 4, we get

[tex]x = \boxed{33.5}$.[/tex]

The y-intercept is the y value when x = 0, or (0 , y)

Based on the graph, your y-intercept is at (0 , 2) or 2

The slope(m) can be found using the slope formula and plugging in 2 points:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

But if you look at the answer choices, if the slope is positive, the line would be going up and to the right

If the slope is negative, the line would be going down and to the right

Answer: Translated (Option C)

Step-by-step explanation:

Two similar triangles  RST was then dilated, to create triangle ZXY.

For dilation, translation should be done.

Dilation is a transformation, which is used to resize the object. Dilation is used to make the objects larger or smaller. This transformation produces an image that is the same as the original shape.

As, ΔRST was dilated to form ΔZXY.

But, this can be done by translation , to create ΔZXY

The following information:

Since Triangle ΔZXY is slightly higher and to the right of triangle ΔRST.

So it should be translated.

so, that it could be dilated for ΔZXY.

Answer:

Step-by-step explanation:

You need to use substitution, to do so, you isolate one of the variables x or y in one equation, and then you substitute that equation into the other.

Since you only need to find x, isolate the y in one of the equations

x - 2y = 4

y = [tex]\frac{x}{2} -2[/tex]

Plug this in and simplify

9x + 2y = 16

9x + 2([tex]\frac{x}{2} -2[/tex]) = 16  Distribute the 2

9x + x - 4 = 16  

10x = 20

x = 2    Your answer is C

Answer:

Yes, there exists one output for every input

Step-by-step explanation:

* Lets revise how to test the function is one-one function

- Draw a horizontal line (parallel to x-axis) and moved it up and down

- If the horizontal line cut the graph in more than one point, then

 the function is not one-one function

- If the horizontal line cut the graph in only one point, then the

 function is one-one function

- That means one output for every input

* Now lets look to the graph

- If we draw a horizontal line and moved it up and down, the line

 will cut the graph in just one point

- That means every x has different value of y

∴ There is no same y-coordinate for two x-coordinates

* Yes, there exists one output for every input

Answer: symmetric or reflexive

Step-by-step explanation:

I'm not forsure but I believe that these are the two options bc the other two aren't forsure sorry dude I'm trying :0

Like last time, we substitute in each one until we find one we see can't work, or just look at them and choose the one that doesn't look right.

D in this case doesn't look right, so we can substitute it in:

-8+8=8

That isn't true, that equation would equal 0.

Hope I helped (again), sorry if I'm wrong!

D. (-2,4) is the answer?

Parallel lines have the same slope so the equation will have the same slope. The y-coordinate is the new y-intercept, so the equation is y = 3x + 8

Hope this helps

Answer:

y = 3x + 5

Step-by-step explanation:

Line y = 3x - 8; slope = 3

Parallel lines, slope is the same so slope of the line that parallel to the line y = 3x - 8 is also 3

Passing thru (1,8)

y - 8 = 3(x - 1)

y - 8 = 3x - 3

y = 3x + 5

Answer:

y = 3x + 5

Answer:

vertical translation of - 6

Step-by-step explanation:

given f(x) = 3x + 3

then f(x) + c is a vertical translation of f(x)

• If c > 0 then a shift of c units up ↑

• If c < 0 then a shift of c units down

shift from + 3 to - 3 is a vertical shift of 6 units down

ANSWER

[tex]y = {( - x)}^{3} - 4[/tex]

EXPLANATION

The parent or base function is

[tex]y = {x}^{3} [/tex]

This function has its y-intercept at the origin.

It has been transformed vertically so that its y-intercept is now at -4.

This is a transformation of the form

[tex]y = {x}^{3} - k[/tex]

where k=4.

The function is also reflected in the x-axis.

The new function is

[tex]y = {( - x)}^{3} - 4[/tex]

The new function is

a) [tex]y = {( - x)}^(3) - 4[/tex]

The parent or base function is

[tex]y = {x}^(3)[/tex]

This function has its y-intercept at the origin.

It has been transformed vertically so that its y-intercept is now at -4.

This is a transformation of the form

[tex]y = {x}^(3) - k[/tex]

where k=4.

Answer:

2nd number line

Step-by-step explanation:

When there is an absolute value inequality of the form  |x+a| ≥ b,

We can say that the solution set (in a number line) would be:

Keeping these points in mind,

|x+3| ≥ 2

we start from x = -3

we go 2 units left and right, so we arrive at x = -5 and x = -1

then we draw arrows to both sides

looking at the choices, we see 2nd answer choices (graph) portrays it correctly.

Answer:

Radius is 13 and Circumferences is 81.64

Step-by-step explanation:

You divide 26 by two to get the radius and multiply 2 time pi times the radius or pi times diameter to get the circumference.

Answer:

radius=13

Circumference=26pi

Area=169pi

Step-by-step explanation:

The radius is half the diameter (SP or PR or PQ). The radius is 13

Area= pi(r)^2

r=radius

r=13

pi(13)^2=169pi

circumference=2pi(r)=(pi)d

r=radius

d=diameter

2(pi)13=26pi

Answer:

18 points

Step-by-step explanation:

We first need to find the percent increase for both Iliana an Fiona.

To do so, we take the absolute value of difference (the score increase) and we compare/divide it by the original score they had.

So, for Iliana, we have a starting score of 65 and an increase of 21 (86-65).

Her percent of increase is 21/65 = 32.3%

For Fiona, she went from 70 and had a 10 points increase (80-70).

Her percent of increase is 10/70 = 14.3%

The difference between the two percent of increase is 18 points (32.3 - 14.3)

Answer with Step-by-step explanation:

Percentage increase in score is calculated by the formula:

[tex]\dfrac{New\ score-Old\ score}{Old\ score}\times 100[/tex]

Iliana’s math grade increased from 65 to 86.

Percentage increase in Iliana's score is:

[tex]\dfrac{86-65}{65}\times 100[/tex]

=[tex]\dfrac{21}{65}\times 100[/tex]

=32.31%

Fiona’s math grade increased from 70 to 80.

Percentage increase in Fiona's score is:

[tex]\dfrac{80-70}{70}\times 100[/tex]

=[tex]\dfrac{10}{70}\times 100[/tex]

=14.28%

Difference between percentage increases=32.31%-14.28%

                                                                       = 18.03%

Hence, difference, rounded to the nearest whole number, between the approximate percent increases is:

18%
