velikii [3]

Answer:

7 in both boxes

Step-by-step explanation:

In the picture, it shows

4 (x - 3) = 20

and then it shows

4 (x) - 4 (3) = 20

so practically you separate the x and 3 and put them in parentheses and then put a 4 next to both of them.

It should be the same as your question.

7 x (8 - 3)

and then separate 8 and 3 and put a 7 next to both of them.

( 7 x 8) - ( 7 x 3)

Hope it helps and have a great day! =D

PLEASE HELP ME WILL MARK BRAINLIEST! Town planners are planning a 500 foot by 700 foot parking lot by making a scale drawing tha

Scilla [17]

Answer:

The approximate value of the scale is 1:67

or the actual value without approximation is 1: 66 2/3 ( 66 while number , two over three)

Step-by-step explanation:

Here, we want to figure out the scale in inches of the drawing to the actual object.

The actual object is 500 ft by 700 ft

while the drawing is 90 inches by 126 inches

Mathematically, we know that 12 inches = 1 foot

So the actual object will be;

500(12) by 700(12)

= 6000 inches by 8400 inches

Now let’s make a division to get the scale;

6000/90 by 8400/126

we get 66.67 as answers on both ends

This is approximately equal to 67

So the scale we have here is 1:67

Consider the line y=9x-8

jasenka [17]

Answer:

y=9x+75

Step-by-step explanation:

since we know that the slope must be the same for two lines to be proportional, we are gonna start there.

so our equation is: y= 9x + b

we need to find b to complete our equation, so substitute in the points we were given.

3 = 9(-8) + b

so now,

3 = -72 + b

now we have to isolate b to find out what it is,

3 = -72 + b

+72 +72

so now: 75= b

Put that back into the starting equation: y = 9x + 75

What is the point slope form of the line with slope 25 that passes through the point (−4, −7)?

Arisa [49]

Answer:

Option A: $y+7 = 25(x+4)$ is the correct answer.

Step-by-step explanation:

The point-slope form of an equation of a line is given by:

$y-y_1 = m(x-x_1)$

Here:

m is the slope of the line

$(x_1,y_1)$ are the coordinates of the point from which the line passes.

Now looking at the given question:

$m = 25\\(x_1,y_1) = (-4,-7)$

Putting the values in the general form of point-slope form of equation of line

$y-(-7) = 25\{x-(-4)\}\\y+7 = 25(x+4)$

Hence, the point-slope form of given line is:

$y+7 = 25(x+4)$

Observing the option given, it can be concluded that Option A: $y+7 = 25(x+4)$ is the correct answer.
