Answer:

Step-by-step explanation:

Use the point-slope formula.

y - y_1 = m(x - x_1) .... x_1 = 3 and y_1 = - 1

m is the slope to x - 3y = 9 because (lines are parallel )

calculate : m by equation x - 3y = 9 :

x = 3y +9

divid by : 3 1/3 x = y + 3

y = (1/3) x - 3 so : m = 1/3

an equation parallel to x - 3y = 9 that passes through the point ( 3, -1 ) is :

y +1 = (1/3)(x - 3)

Which linear function represents the line given by the point-slope equation y + 7= -2/3 (x+6)

kumpel [21]

$y + 7 = - \frac{2}{3}(x + 6) \\$

$y + 7 = - \frac{2}{3}x - 4 \\$

Subtract sides -7

$y = - \frac{2}{3}x - 4 - 7 \\$

Thus ;

$y = f(x)= - \frac{2}{3}x - 11 \\$

So the correct answer is (( A )) .

A line has a slope of -1/2 and a why intercept of -2

Mice21 [21]

Answer:

y = -1/2x - 2

Step-by-step explanation:

The formula of the slope-intercept is y = mx + b. The m is the slope while y is the y-intercept.

y = -1/2x - 2

Help with number 12 please

Troyanec [42]

The fifth power of ten would not be represented.
Each individual digit would be shown as a power of ten.
982 would be the sum of:
9 times 100. (100 is 10 to the second power)
plus
8 times 10. (10 is 10 to the first power.)
plus
2 times 1. (I is 10 to the zero power.)

The only significant digit represented by a zero is the "hundred thousands"
(100,000 is 10 to the fifth power.)

Mr. Webb gave his waiter a $8.60 tip on a $50 bill. What percent did he give the waiter?

Dominik [7]

8.60 = X 
50 100

"Percent" means "out of one hundred" (Latin).
Multiply the top by two, since 100 is twice 50, and the fractions will be equal.
The answer is 17.2%.
