Answer: You find it by using slope

Step-by-step explanation

If the graph is rising from left to right, like climbing a hill, the slope is positive (on a graph, you could count up y units divided by right x units). If it is going down from left to right (like sliding down a hill), the slope is negative (on a graph you have to count down y units and right x units).

ex: y = 5x + 3 is an example of the Slope Intercept Form and represents the equation of a line with a slope of 5 and and a y-intercept of 3. y = −2x + 6 represents the equation of a line with a slope of −2 and and a y-intercept of 6.

The longest side of a triangle is 5 in longer than the shortest side. The medium side is 4 in longer than the shortest side. If

aliina [53]

Answer: Shortest side = 6 inches, Medium side = 10 inches and Longest side = 11 inches

Step-by-step explanation: The perimeter has been given as 27 inches, and we know that the perimeter of any given figure is the addition of all sides. The sides are unknown yet, but we have clues as follows;

The longest side is 5 inches longer than the shortest side, hence the longest side equals s + 5. The medium side is 4 inches longer than the shortest side, hence the medium side equals s+ 4. Th shortest side remains s.

Therefore with the perimeter given as 27, we now have the expression;

s + s + 4 + s + 5 = 27

3s + 9 = 27

Subtract 9 from both sides of the equation

3s = 18

Divide both sides of the equation by 3

s = 6

Hence, the sides of the triangle are given as 6, (6+ 4) and (6+ 5), which is,

6 inches, 10 inches and 11 inches.

HELP ASAP WILL GIVE BRAININST IF:

DiKsa [7]

Answer:

slope is -7/8

Step-by-step explanation:

first remember these to formulas:

$m= \frac{y2-y1}{x2-x1}$

and

$y-y1 = m(x-x1)$

now insert the points:

$\frac{-3-4}{3-(-5)}$ = -7/8

slope intercept form:

y - 4 = -7/8(x - (-5)

y - 4 = -7/8(x + 5)

y = -7x/8 - 3/8

Have a nice day!

The circumference of a circle is 138.16 centimeters. What is the area of the circle?

vodomira [7]

Circumference formula tells you $C=2 \pi r$

 $C=2 \pi r$
 $138.16=2 \pi r$
 $21.99= r$
 $r=21.99cm$ 
The formula to find the area of a circle is $A= \pi r^2$

 $A= \pi r^2$
 $A= \pi (21.99)^2$
 $A= \pi (483.56)$
 $A= 1519cm^2$
