Answer:

slope = -5 ÷ 4

Step-by-step explanation:

The equation of line can be written as,

y = mx + c

where, m is slope

and c is intercept of line.

So, transforming the given equation in above standard equation.

5x + 4y - 1 = 0

⇒ 4y = -5x + 1

⇒ $y = \frac{-5}{4}x +\frac{1}{4}$

Now comparing this equation with standard equation. We get,

$m =\frac{-5}{4}$

and $c = \frac{1}{4}$

Hence, Slope = $m =\frac{-5}{4}$

A car with a cost price of $5200 is sold at a profit of 15%. Calculate the selling price

andriy [413]

Answer:

We are given the initial price of a car and we are also told that the car sold for a 15% profit which means that the price that the car was sold for is 15% more than it's initial price. This is just a simple multiplication problem which we multiply the initial price by the total percentage plus 0.15

$Sold\ Price = Initial\ Price *(Total\ Percentage+Profit\ Percentage)$

$Sold\ Price = \$5200*(1+0.15)$

$Sold\ Price = \$5200*(1.15)$

$Sold\ Price = \$5980$

Therefore, our final answer is that the selling price was $5980

Hope this helps!

Plz help!

zloy xaker [14]

The factored expression is: 3(5n-6)
The GCF between 15 and 18 is 3. So you would divide both numbers by 3. That would leave you with 5 taking the place of 15 and 6 taking the place of 18. Then you would fill in the blanks. Three multiplied by the expression 5n-6 would give you your original expression of 15n-18.

A gallon of paint covers 1 1/3 walls. How many gallons does it take to cover 1 wall? How about 3 walls?

Alekssandra [29.7K]

Answer:

1 wall is 0.75 gallons. 3 walls is 2.25 gallons.

Step-by-step explanation:

if 1 gallon covers 1 1/3 wall, divide 1/1.3333 = 0.75

multiply 0.75(1 wall) by 3.... 0.75×3=2.25

What’s the correct answer for this question?

weqwewe [10]

Answer:

Last answer choice

Step-by-step explanation:

The AAS congruence theorem uses two adjacent angles, followed by a side length on the side (not in between the angles.) Therefore, the first answer is ruled out (because it deals with angles and not sides), and the second answer is ruled out because it involves side lengths between angles. LP=MO may be true, but it does not compare the two triangles that we are interested in. However, the last answer choice is correct, because a midpoint divides a line exactly in half, meaning that both halves are the same length and therefore congruent. Therefore, the last answer choice is correct. Hope this helps!
