What is the slope of the line?

Mathematics
1 answer:
sineoko [7]3 years ago
4 0

Answer:

3/4

Step-by-step explanation:

You can do this two different ways. Both include picking two points where the line crosses a corner. I'm using (0,-1) and (4,2). Now here you can either use

Slope=\frac{Rise}{Run}

or \frac{y2-y1}{x2-x1}  

If you use the first one start at point (0,-1) and go to point (4,2) and count how many it goes up (rise) and then put that over how many it goes to the right (run).

If you use the second one then plug in the numbers.

y2=second y point

y1=first y point

x2=second x point

x1=first x point

\frac{2-(-1)}{4-0}   Now just solve.

\frac{3}{4}

Which expressions are equivalent to 8 (negative 10 x + 3.5 y minus 7)? Select two options.
Elza [17]

Question is Incomplete; Complete question is given below.

Which expressions are equivalent to 8 (negative 10 x + 3.5 y minus 7)? Select two options. Negative 80 x + 24.5 y minus 56 Negative 80 x + 28 y minus 56 80 x + 28 y + 56 4 (negative 20 x + 7 y minus 14) Negative 4 (negative 20 x + 7 y minus 14)

Answer:

Negative 80 x + 28 y minus 56

4 (negative 20 x + 7 y minus 14)

Step-by-step explanation:

Given:

8(-10x+3.5y-7)

We need to find the equivalent expression for given expression.

Solution:

8(-10x+3.5y-7)

First we will apply distributive property for given expression.

a(x+y) =ax+ay

So we get;

8\times-10x+8\times3.5y-8\times7\\\\-80x+28y-56

Hence first expression equivalent to given expression is -80x+28y-56.

Now again evaluating the expression we get;

We will take 4 as common factor from the expression we get;

-4\times20x+4\times7y-4\times14\\\\4(-20x+7y-14)

Hence second expression equivalent to given expression is 4(-20x+7y-14).

PLEASE HELP ASAP!!! ILL GIVE BRANLIEST *EXTRA POINTS* !! PLEASE DONT SKIP :(((
mezya [45]

Answer:

92.5 centimeters.

Step-by-step explanation:

The one-meter snake showed up as 2 cm in the developed photo. Since there are 100 centimeters in a meter, you subtract the length of the snake in centimeters by the length it shows up in the picture. 100-2 is 88, so that would be the difference. To find the length of the wall, you add the difference to how it showed up in the picture. 88+4.5=92.5.

Garth estimated the height of the door to his classroom in meters.what is a reasonable estimate?
insens350 [35]
A reasonable estimate is an educated guess made by an observer based on that person's current knowledge and following observations. For example, If Garth knew that he was 1.2 meters tall, and he observed that the door was approximately twice his own height, Garth could then make the reasonable estimate that the door is about 2.4 meters tall.
