Answer: -3,4

Step-by-step explanation:

The transformation can be defined as the introduction of a new set of mathematical coordinates. The rule that can describe the translation of the black triangle into the blue triangle is T<-3, -4>(x,y).

The transformation can be defined as the introduction of a new set of mathematical coordinates that are declared to be different functions of the original coordinates.

The translation can be found by observing any one coordinate of the image and the preimage.

Hence, The rule that can describe the translation of the black triangle into the blue triangle is T<-3, -4>(x,y).

Answer:

a) [tex]y=\frac{23}{6} x-156[/tex]

b) [tex]\frac{268}{3}[/tex]

Step-by-step explanation:

Formulas for linear equations:

Slope-intercept: [tex]y=mx+b[/tex], where m is the slope and b is the y-intercept

Point-slope: [tex]y-y_1=m(x-x_1)[/tex], where (x₁, y₁) is a point on the function and m is the slope.

a) We are given two points. If you're given two points (x₁, y₁) and (x₂, y₂), the slope m is given by the formula:

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

Let's mark the temperature on the x-axis, and the number of chirps per minute on the y-axis. So, we have the following points: (60, 74), and (72, 120). Calculating the slope m between these two points:

[tex]m=\frac{120-74}{72-60}[/tex]

[tex]m=\frac{23}{6}[/tex]

Since we have the x and y coordinates of a point on the function, we can write an equation in point-slope form, which will help us to find the y-intercept. We need the y-intercept in order to write the slope intercept form of the equation. We will use the point (60, 74) here, although you can also use (72, 120) if you want.

Point-slope form equation of the linear function:

[tex]y-74=\frac{23}{6} (x-60)[/tex]

Now that we have the point-slope equation of the function, we can find the y-intercept. The y-intercept is the point on the function where the graph crosses the y-axis (when the x-value is 0). So, we plug in 0 for x into the equation and solve for y:

[tex]y-74=\frac{23}{6} (0-60)[/tex]

[tex]y=-230+74[/tex]

[tex]y=-156[/tex]

Now that we have the y-intercept value of the function, we can write an equation in slope-intercept form:

[tex]y=\frac{23}{6} x-156[/tex]

b) Since we marked the temperature on the x-axis, we can just plug in the number 64 as the x-value into the equation we have. y will be the number of chirps per minute when the temperature is 64º.

[tex]y=(\frac{23}{6} *64)-156[/tex]

[tex]y=\frac{736}{3} - \frac{468}{3}[/tex]

[tex]y=\frac{268}{3}[/tex]

Step-by-step explanation:

The question is incomplete. Here is the complete question;

A kid traveled a distance of 9 km by bike, and then walked a distance of x km.

a.Find the total distance traveled in terms of  x

b. If the total distance was less than 30 km, form an inequality in x, and

then solve it!

a) Total distance = distance travelled by bike + distance walked

Total distance = 9km + xkm

Total distance = (9+x)km

b)  If the total distance was less than 30 km, the inequality representing this is;

9+x < 30

Subtract 9 from both sides;

9+x-9 < 30-9

x < 21

hence the solution to the inequality is x< 21

Answer:

20m

Step-by-step explanation:

Given the formula that modelled the height given as;

h=30+40t-5t^2

At t = 4s

h=30+40(4)-5(4)^2

h = 30+160-80

h = 160-60

h = 110m

At t = 2s

h=30+40(2)-5(2)^2

h=30+80-20

h = 110-20

h= 90m

Difference in height = 110-90 = 20m

Hence the height is 20m higher above the ground at 4s than at 2s

Answer: -6i

Step-by-step explanation:

We want to imagine where the shading should be, and with that determine which point is a solution for both inequalities. We will see that the solution is the point (7, -8)

In this case, the inqualities are:

You can see that in both cases, y is smaller than the line, thus, for both inequalities, we must shade the part that is below the lines.

With that in mind, the region of solution will be the region that is below both lines at the same time, and that region will be the "triangle" that you can see at the middle below the horizontal axis.

Now that we know the region of solutions, we only need to see which point belongs there, from the given options the only that belongs to that region is the point (7, -8), which means that this point is a solution for both inequalities.

Answer:

41 minutes

Step-by-step explanation:

If she jogged 15 minutes more on Sunday than Saturday, we can find how many minutes she jogged on Sunday by adding 15 to Saturday's amount:

So, add 15 to 26:

15 + 26

= 41

So, she jogged 41 minutes on Sunday.

Answer:

see below

Step-by-step explanation:

1. (x² - 4x - 10) + (x² - 9x + 3)

=  x² - 4x - 10 + x² - 9x + 3

=  x² + x² - 4x - 9x + 3 - 10

4. (3x² - x + 1) + (15 - 9x - 2x²)

=  3x² - x + 1 + 15 - 9x - 2x²

= 3x² - 2x² - x - 9x + 1 + 15

7.  (6 - 2x + 7x²) - (10x - 3 + 3x²)

=   6 - 2x + 7x² - 10x + 3 - 3x²

=  7x² - 3x² - 2x - 10x + 6 + 3

Answer:

Hebrew National since the cost is only 0.73

Step-by-step explanation:

First we need to identify the cost of each hotdog for each brand. I'll go by in order.

Ball Park:

We know that it cost $6.95 and it's 8 dogs for each one. Meaning all we have to do is divide the price by the amount of hot dogs.

"Price/Hotdogs per package"

In order

6.95/8=0.86875 or 0.87

8.20/10=0.82

7.35/8=0.91875 or 0.92

17.50/24=0.7291666 or 0.73

Since we're dealing with currency we would most likely round it by the nearest hundredth so the true answer would be $0.87.
