Answer:

y + 9 = -0.4(x-7)

Step-by-step explanation:

in slope form , we will use y - y1 =m ( x - x1) ,

which will be y + 9 = -2/5(x-7) ,

in reduced form , we have y + 9 = -0.4(x-7)

it takes one fourth of a gallon of paint covers one fifth of a car how much paint covers the whole car

Komok [63]

Answer:

The volume of paint that covers the whole car is $1\frac{1}{4}$ gallons or one and a quarter gallons.

Step-by-step explanation:

Let the volume of paint required to cover whole car be 'x'.

Given:

Volume of paint to cover one-fifth of a car = one-fourth of a gallon.

We use unitary method to determine the volume of paint required.

∵ One-fifth of a car requires paint = $\frac{1}{4}\ gal$

∴ Whole volume of car requires paint = $\frac{\frac{1}{4}}{\frac{1}{5}}$

$=\frac{1}{4}\times \frac{5}{1}\\=\frac{5}{4}\\=1\frac{1}{4}\ gal$

Therefore, the volume of paint that covers the whole car is $1\frac{1}{4}$ gallons or one and a quarter gallons.

Solve for x. −2x+3=15 Enter your answer in the box. x =

Elza [17]

Answer:

x = -6

Step-by-step explanation:

Step 1 :

Pulling out like terms :

1.1 Pull out like factors :

-2x - 12 = -2 • (x + 6)

Equation at the end of step 1 :

Step 2 :

Equations which are never true :

2.1 Solve : -2 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2 Solve : x+6 = 0

Subtract 6 from both sides of the equation :

x = -6

One solution was found :

x = -6

PLEASE SOLVE THIS :(

Answer:

10.5 %

Skills needed: Financial Math Essentials

Step-by-step explanation:

1) First, before getting started, let's assume the price of the product is $x$ . This variable will be used a lot throughout the problem ( $x$ ).

2) Marking a price above means increasing the price in order to make money off of the purchased product. When raising something by $y$ percent, the new price would be $x + \frac{y}{100}*x$ .

---> In this case, the price increased by $\textbf{30}$ percent.

This means that it would be: $x+\frac{30}{100}x = x+0.3x=1.3x$

New price is: $1.3x$

3) The shopkeeper is then offering a $\textbf{15}$ percent discount off of this marked price. When offering a $b$ percent discount price, the new price (with discount), expressed algebraically is: $a-\frac{b}{100}a$
