Answer:

18 rooms.

Step-by-step explanation:

Because it takes 1.5 gallons of paint to cover the walls in 3 rooms, if we divide on 3 on each side, we will get 0.5 gallons of paint per room.

The equation is r = 0.5g.

If we apply this formula, and multiply both sides by 18, we will get 18r = 9g.

The answer is 18 rooms.

Answer:

1/3 is the y intercept

Step-by-step explanation:

f(x) = -2/9x + 1/3

This is written in slope intercept form

y = mx+b where m is the slope and b is the y intercept

-2/9 is the slope and 1/3 is the y intercept

Answer:

d * 0.20 = x

Step-by-step explanation:

In order to calculate the total cost of the DVD's we first need to change the percentage of the discount that Miguel's manager is giving him into decimal format by dividing the percentage by 100 like so...

20 / 100 = 0.20

Now that we have the decimal value we can multiply it by the actual cost of the DVDss to find the total cost before taxes. Since we do not have the actual DVD cost we would make the following equation where x is the final total cost and d is the initial cost of the DVDs.

d * 0.20 = x

use the calculator but the answer is 18.1

Answer:

slope is -1, y intercept is 5

Step-by-step explanation:

slope formula is y1-y2 over x1-x2

plug in formula

u get the slope is -1

Answers:

Slope = 4

Y intercept = 5

======================================================

Explanation:

Start at the point (-1,1) which is one point on the line. Then move up 4 units and to the right 1 unit to get to (0,5). This is another point on the line.

Therefore the slope = rise/run = 4/1 = 4.

You could also use the slope formula m = (y2-y1)/(x2-x1)

---------------

The y intercept is 5 since the line crosses the y axis at this location. More specifically this is the point (0,5). For any y intercept, x = 0.

The equation of this line in slope intercept form is y = 4x+5. Compare it to y = mx+b and we have m = 4 as the slope and b = 5 as the y intercept.

Answer:

x = -63

Step-by-step explanation:

To isolate x, you must first do the reciprocal on both sides, so you do 7/x times x/7 cancel that out, then do it on the other side, so -9/1 x 7/x = -63.

Answer:

x = -63

Step-by-step explanation:

To isolate x, you must first do the reciprocal on both sides, so you do 7/x times x/7 cancel that out, then do it on the other side, so -9/1 x 7/x = -63.

Answer:

-49/50

Step-by-step explanation:

-39v=4v+7(v+7)

Distribute

-39v = 4v +7v+49

Combine like terms

-39v = 11v+49

Subtract 11 v from each side

-39v-11v = 11v-11v +49

-50v = 49

Divide by -50

-50v/-50 = 49/-50

v = -49/50

Answer:

v= - 49/50

Step-by-step explanation:

-39v=4v+7(v+7)

open the parentheses by multiplying both v&7 by 7:

-39v=4v+7v+49

add like terms:

-39v-4v-7v=49

-50v=49

divide both sides by -50:

v= - 49/50

Complete square form of the equation  16t² - 96t + 48 = 0 is (t -3)² = 6.

A quadratic equation is an equation of second order. Quad implies the square power, it is also called equation of degree 2.

The standard form of a quadratic equation is ax² + bx + c = 0.

Where a, b and c are constants.

The given quadratic equation is,

16t² - 96t + 48 = 0

To find the square for the quadratic equation,

Simplify the quadratic equation,

16(t² - 6t + 3 ) = 0

Add 96 in whole equation,

16(t² - 6t + 3 + 6) = 16 x 6

16(t² - 6t + 9) = 96

t² - 6t + 9 = 96 /16

t² - 6t + 9 = 6

(t -3)² = 6

The required square form of the equation is (t -3)² = 6.

Answer:

D: x+6

Step-by-step explanation:

The factor of the polynomial function f(x) is x + 6

The factors of a polynomial are the quotients and the zeros of the polynomial

The points on the polynomial curve are given as:

(-6,0), (-3,0) and (0,0)

So, we have:

x = -6

x = -3

x = 0

Equate the above equations to 0

x + 6 = 0

x + 3 = 0

x = 0

Hence, the factor of the polynomial is x + 6

Answer:

x= -1/2

y= 4.5

Step-by-step explanation:

4x+2y=7

3x-5y=-24

First either make the x or y's the same. It is easier here to make the y's the same.

Multiply each of the first equation by 5 and the second one by 2.

x5   4x+2=7   x5 = 20x+10y=35

x2   3x-5y=-24  x2= 6x-10y=-48

20x+10y=35

6x-10y=-48         +both equations

26x=-13

x=-1/2

Now substitute to find y.

List out the perfect squares

{1,4,9,16,25,36,49,64,81,100,121}

We stop once we reach 117 or just a bit higher.

---------------------------

Then notice that

[tex]16 < 19 < 25 \ ... \ \text{19 between the squares 16 and 25}\\\\\sqrt{16} < \sqrt{19} < \sqrt{25} \ ... \ \text{ apply square root to all sides}\\\\4 < \sqrt{19} < 5[/tex]

Which shows [tex]\sqrt{19}[/tex] is between 4 and 5. Therefore, the two closest integers to [tex]\sqrt{19}[/tex] are 4 and 5.

---------------------------

We follow the same steps for [tex]\sqrt{50}[/tex]

So,

[tex]49 < 50 < 64\\\\\sqrt{49} < \sqrt{50} < \sqrt{64}\\\\7 < \sqrt{50} < 8[/tex]

So the square root of 50 is between 7 and 8.

---------------------------

And finally,

[tex]100 < 117 < 121\\\\\sqrt{100} < \sqrt{117} < \sqrt{121}\\\\10 < \sqrt{117} < 11[/tex]

---------------------------

Using a calculator, we find that

[tex]\sqrt{19} \approx 4.36[/tex]

[tex]\sqrt{50} \approx 7.07[/tex]

[tex]\sqrt{117} \approx 10.82[/tex]

which helps confirm our answers.
