which problem could be solved by evaluating the expression 7 x (-3)?​

Answer:

58.8 feet per second

Step-by-step explanation:

At 40 miles per hour, you are traveling 58.8 feet per second. To convert miles per hour to feet per second, multiply the miles per hour figure by 1.47. There are 5280 Feet in a mile and 3600 Seconds in an hour. If you divide 5280 Feet by 3600 Seconds (5280 FT /3600 SEC.), you get 1.47.

Answer:

Drew = 92 pictures, Danielle = 26 pictures

Step-by-step explanation:

Amount of pictures Drew has = x

Amount of pictures Danielle has = y

First make a system of equations:

x + y = 118

x = 3y + 14

Then solve with substitution:

(3y + 14) + y = 118

4y = 104

y = 26

x + 26 = 118

x = 92

Answer:

Just count them

Step-by-step explanation:

Answer:

1) 280

There are 60 minutes in an hour. 60/15 is four. 4*70 is 280

2)384

640/5=128

128*3=384

3) 24

216/9=24

4)3

4.5=18/4

six times as many as you need.

1/2 times 6 is 3.

Answer:

This would be point M.

Step-by-step explanation:

Hope this helps!

Answer:

M

Step-by-step explanation:

(3.75, -2.25)

The first coordinate is the x coordinate which means left or right.

Since it is positive we go to the right 3.75 units

The second coordinate is the y coordinate which means up or down

Since it is negative we go down 2,25 units

The point is labeled M

Answer:

point slope form: y + 4 = 3/8 (x + 5)       slope intercept: y = 3/8x - 17/8

Step-by-step explanation:

y2 - y1 / x2 - x1

-1 - (-4) / 3 - (-5)

slope = 3/8

y + 4 = 3/8 (x + 5)

y = 3/8x + b

-1 = 3/8(3) + b

-1 = 9/8 + b

-17/8

y = 3/8x - 17/8

Answer:

it should be 250m

Step-by-step explanation:

Bus X travels 40m for 2h which gives you 80m and Bus Y travels 60m for 11/2h which gives you 330m so the difference in miles is 250m

Answer:

Step-by-step explanation:

The slope is:

The y-intercept is:

The line is:

A. The x-Intercept of the graph of k is 8.

B. The slope of the graph of k is 2.

C. The graph of k passes through (-1, -8).

D. The zero of k is 3.

The slope of the graph of k is 2.

The correct statement is B.

Given that the graph of linear function k passes through the points (-3, 0) and (1, 8).

We need to check which option is correct.

To determine the correct statement, let's first find the equation of the linear function k using the given points (-3, 0) and (1, 8).

The slope of a linear function is given by:

slope = (change in y) / (change in x)

Using the points (-3, 0) and (1, 8):

slope = (8 - 0) / (1 - (-3))

slope = 8 / 4

slope = 2

So, the slope of the graph of k is 2.

Now we can write the equation of the linear function using the slope-intercept form: y = mx + b, where m is the slope, and b is the y-intercept.

Using the point (1, 8):

8 = 2 × 1 + b

8 = 2 + b

b = 8 - 2

b = 6

Now, the equation of the linear function k is:

y = 2x + 6

Now, let's evaluate the given statements:

A. The x-Intercept of the graph of k is 8.

To find the x-intercept, we set y = 0 and solve for x:

0 = 2x + 6

2x = -6

x = -3

The x-intercept is -3, not 8. So statement A is false.

B. The slope of the graph of k is 2.

We already found earlier that the slope of k is 2. So statement B is true.

C. The graph of k passes through (-1, -8).

Let's check if (-1, -8) satisfies the equation of k:

-8 = 2 × (-1) + 6

-8 = -2 + 6

-8 = 4

The equation is not satisfied, so statement C is false.

D. The zero of k is 3.

To find the zero of k (the x-value where y = 0), we set y = 0 and solve for x:

0 = 2x + 6

2x = -6

x = -3

The zero of k is -3, not 3. So statement D is false.

In conclusion:

Statement A is false.

Statement B is true.

Statement C is false.

Statement D is false.

Answer:

x = 8

Step-by-step explanation:

Supplementary angles add up to 180 degrees to make a straight line.

The red square in one of them indicates that it is 90 degrees on their side which means that it is 90 degrees on the other where (6x+2) and 40 degrees are.

(6x+2) + 40 = 90

6x + 42 = 90

6x = 48

x = 8

Answer:

8^3 x 12^3

Step-by-step explanation:

The finance charge for the car loan Sarah took rounded to the nearest 100 dollars is 700 dollars.

A percentage is a value per hundredth. Percentages can be converted in decimals by dividing the percentage value by 100 it can also be simplified to keep it in a fraction form.

Given Sarah is taking a loan of 24,400 dollars for a new car.

Also given is the finance charge for this car loan is 2.88%.

We know 2.88% of 24400 dollars is,

= (2.88/100)×24400 dollars.

= 0.0288×24400 dollars.

= 702.72 dollars.

Which rounded to the nearest 100 dollars is 700 dollars.
