What is the equation of a line that passes through the point (5, −4) and is parallel to the line whose equation is 2x + 5y = 10?

3241004551 [841]

Rewrite the given equation in slope intercept form:

5 y = 10 – 2 x

y = - 0.4 x + 2

Since the two lines are parallel, therefore they have similar slope which is – 0.4, so the equation is:

y = - 0.4 x + b

Given that x = 5, y = -4, find for b:

-4 = - 0.4 (5) + b

b = -2

So the answer is:

y = - 0.4 x – 2

2 x + 5 y = - 10

Three different golfers played a different number of holes today. Rory played 9 holes and had a total of 42 strokes. Alicia play

choli [55]

Answer:

Alicia is the golfer who has had the lowest number of strokes per hole

Step-by-step explanation:

we know that

The unit rate of the number of strokes per hole is equal to divide the number of strokes by the number of holes

Let

x ----> the number of strokes

y ----> the number of holes

we have

Roy

$x=42\ strokes\\y=9\ holes$

$\frac{x}{y}=\frac{42}{9}=4.67\ strokes\ per\ hole$

Alicia

$x=79\ strokes\\y=18\ holes$

$\frac{x}{y}=\frac{79}{18}=4.39\ strokes\ per\ hole$

Rickie

$x=123\ strokes\\y=27\ holes$

$\frac{x}{y}=\frac{123}{27}=4.56\ strokes\ per\ hole$

Compare

4.39 < 4.56 < 4.67

therefore

Alicia is the golfer who has had the lowest number of strokes per hole

C. 42

because if you divide 26.2 divided by 5 = 5.24 then you times it by 8 and you will get 41.92 and you will round it to get 42

Arlecino [84]

Answer:

$x = 16$

Step-by-step explanation:

5x-12=3x+20

plus 12 both sides

5x=3x+32

-3x both sides

2x=32

divide by 2 both sides

x=16
