Answer:

The y-intercept of the line is the point (0,-41)

Step-by-step explanation:

we have the points

(-36,-117),(-27,-98) and (-18,-79)

step 1

Find the slope of the linear equation

The formula to calculate the slope between two points is equal to

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

take the points

(-27,-98) and (-18,-79)

substitute the values

$m=\frac{-79+98}{-18+27}$

$m=\frac{19}{9}$

step 2

Find the equation of the line in point slope form

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

we have

$m=\frac{19}{9}$

$point\ (-18,-79)$

substitute

$y+79=\frac{19}{9}(x+18)$ ----> equation in point slope form

step 3

Convert the equation in slope intercept form

$y=mx+b$

where

m is the slope

b is the y-coordinate of the y-intercept

isolate the variable y

$y+79=\frac{19}{9}x+(18)\frac{19}{9}$

$y=\frac{19}{9}x+(18)\frac{19}{9}-79$

$y=\frac{19}{9}x+38-79$

$y=\frac{19}{9}x-41$

therefore

$b=-41$

The y-intercept of the line is the point (0,-41)

Explain why the expression 7•3x is not equal to the expression 21x

Firdavs [7]

Working out the expression 7(3ˣ) is first to calculate the value of 3ˣ then multiply the answer to 7.

For example, let x = 2
Then 7(3ˣ) = 7(3²) = 7 × 9 = 63

With the same value of x = 2, calculating 21ˣ = 21² = 441, which isn't the same answer with the expression 7(3ˣ)

Jamie has $114.56 in her savings and count and her bank just raised the interest paid on her savings account by 1/2%. if her old

zaharov [31]

Answer:

0.5025%

Step-by-step explanation:

The question is on increase and decrease

The old interest rate= .5%⇒0.5%

percentage increase= 1/2%= 0.5%

New rate= it requires you to increase 0.5 by 0.5%

New rate is ⇒100%+ 0.5%=100.5%

New rate⇒(100.5/100)×0.5 =0.5025

New rate as a decimal is 0.5025%
