Answer:

10. y=\frac{3}{5}x+7.2

11A. m=-\frac{3}{5}

11B. m=\frac{5}{3}

Step-by-step explanation:

10. Let's first write the slope-intercept form down and fill in the information we got (which is not much).

y=mx+b\\y=\frac{3}{5}x+b

Now we just need to find the b; the y intercept.

To do that, we plug in the point given (-2,6).

6=\frac{3}{5}(-2)+b\\6=-\frac{6}{5}+b\\6+\frac{6}{5}=b\\b=7.2

y=\frac{3}{5}x+7.2

------------------------------------------------------

A parallel line always has the same slope as its pair

11A. m=-\frac{3}{5}

A perpendicular line has it's slope same as it's pair, <em>but</em> it is multiplied by -1 and the numerator and denominator are switched around.

11B. m=\frac{5}{3}

nswer:

209.8

Step-by-step explanation:

the bottom is = 11 * 5

two of the sides are 11 * 9.3 / 2    because they are triangles, and then times 2 because there are two of them

the other two sides are 10.5 * 5 / 2 , and the * 2 because there are two of them again.

(11 * 5) + (11 * 9.3 * 2 / 2) + (10.5 * 5 * 2 / 2) =209.8

ΔHAT is similar to ΔCAN.
LenKa [72]

In similar triangles, the ratios of corresponding sides are equal.

This means

y/6=5/(4+5)

Cross multiply

y=5*6/(4+5)=30/9=10/3 (or 3 1/3)

Write an equation of a line in point-slope, slope-intercept, and standard form that has
Inga [223]

Answer:

(a) y + 4x - 14 = 0

(b) y = -4x + 14

(c) y + 4x = 14

Step-by-step explanation:

The formula for calculating the equation of line in point - slope form is given as :

y-y_{1}  = m(x-x_{1} )

where m is the slope

Given from the question :

m = - 4

x_{1} = 2

y_{1} = 6

Substituting into the formula , we have :

y - 6 = - 4(x - 2)

y - 6 = -4x + 8

y + 4x - 6 - 8 = 0

y + 4x - 14 = 0

Therefore :

(a) the equation of the line in point - slope form is y + 4x - 14 = 0

(b) to write it in slope - intercept form , we will make y the subject of the formula , which will give : y = -4x + 14

(c) the equation of line in standard form is ; y + 4x = 14

What is the percent of change from 60 to 87?
stiv31 [10]

Answer:

45% increase

Step-by-step explanation:

The new number (87) is bigger than the original number (60), so this is a percent increase.

To find the percent of change, which in this case is a percent increase, take the change amount and divide by the original, then convert to a percent.

Subtract to find the change.

87 - 60 is 27.

27 is the amount of change.

change/original

= 27/60

= .45

Times by 100 to change to a percent.

.45 × 100

= 45%
