What is the equation of the line that passes through the point (−1,−3) and has a slope of 3?

Answer:$14.50

Step-by-step explanation:

Divide 224.75 by 15.5 and you will get the cost for per week.

Answer:

Not a solution.

Step-by-step explanation:

4 < 2(7) - 15

4 < 14-15

4 < -1

Answer:

not a solution

Step-by-step explanation:

Substitute the x- coordinate of the point into the right side of the inequality and compare the result to the left side, that is

2(7) - 15 = 14 - 15 = - 1

Is 4 < - 1 ← no 4 > - 1

Thus (7, 4 ) is not a solution of the inequality

Answer: 25.9

Step-by-step explanation:

Answer:

The length is 12 cm, and the width is 9 cm.

Step-by-step explanation:

The length and width of a rectangle as legs form a right triangle with the diagonal of the triangle as the hypotenuse.

We can use the Pythagorean theorem to write an equation.

Let the width = w = leg a

The length = w + 3 = leg b

The diagonal = the hypotenuse = 12 = c

a^2 + b^2 = c^2

w^2 + (w + 3)^2 = 15^2

w^2 + w^2 + 6w + 9 = 225

2w^2 + 6w - 216 = 0

w^2 + 3w - 108 = 0

(w + 12)(w - 9) = 0

w + 12 = 0   or   w - 9 = 0

w = -12   or   w = 9

Since a width cannot be a negative number, we discard the solution w = -12.

width = w = 9

length = w + 3 = 9 + 3 = 12

Answer: The length is 12 cm, and the width is 9 cm.

Answer: Recipes 1 and 3 have the same proportion.

The unit rate is 1 cup of pineapple juice for 2¹/₂ cups of punch

To make 3 cups of punch, there would be 1.2 cups of pineapple juice.

To make 30 cups of punch, there would be 12 cups of pineapple juice.

Step-by-step explanation:

To find proportions, divide the amounts

2/5 = 0.4   7.2/20 = 0.36   6.4/16 = 0.4

I added the 30 cup batch because it seems unlikely that anyone would want to make only 3 cups of punch.

Answer:

r = 2

r = -1

Step-by-step explanation:

So first, we need to get this is order of: ax^2 + bx + c

3r^2 - 6 - 3r

3^2 - 3r - 6

the formula is: -b ± √b^2 -4ac/2a

"ax^2 + bx + c" = "3^2 - 3r - 6"

a = 3

b = -3

c = -6

-b ± √b^2 -4ac/2a

-(-3) ± √(-3)^2 -4(3)(-6)/2(3)

3 ± √9 + (-12)(-6)/6

3 ± √9 + (72)/6

3 ± √9 + 72/6

3 ± √81/6

3 ± 9/6

3 - 9/6

-6/6

-1 = r

3 + 9/6

12/6

2 = r

Answer:

[tex]x=3\sqrt{2}\\[/tex]

Step-by-step explanation:

Since the smaller triangles have a side of the same length, they share one side, and the included angle is 90°, the triangles are congruent.

This means the length of the side to the left is also x as shown in the image below.

The bigger triangle is also right and has side lengths of x, x, and 6 (the hypotenuse), thus:

[tex]x^2+x^2=6^2[/tex]

Operating:

[tex]2x^2=36[/tex]

[tex]x^2=18[/tex]

Since 18=9*2

[tex]x=\sqrt{9*2}[/tex]

[tex]\mathbf{x=3\sqrt{2}}[/tex]

The options are not clear enough, so I cannot make a choice.

Answer: Sitting fee - 32$

Step-by-step explanation:

This is a system of equations(let x represent the sitting fee)

x+6y=50

x+11y=65

You want to isolate the x variable - x+6y-6y=50-6y ; x = 50-6y

Input this into the 2nd equation: 50-6y+11y=65 ; 50+5y=65

Subtract 50 from both sides. 5y=15 (Divided 5y on both sides) ; y=3

Now that y = 3 input this into any equation I choose the 1st one.

x+6(3) = 50 ; x + 18 = 50 (Subtract 18 on both sides to get x)

x = 32

Prove: 32 + 6(3) = 50 ; 32+18 = 50 ; 50 = 50 True

Answer:

(100,1) (50,2) (25,4) (20,5) (10,10)

Step-by-step explanation:

Given

[tex]V = l * w * h[/tex]

[tex]h = 10cm[/tex]

[tex]V = 1000cm^3[/tex]

Required

Determine the possible values of l and w

We start by substituting 1000 for V and 10 for h in t he given formula

[tex]V = l * w * h[/tex]

[tex]1000 = l * w * 10[/tex]

Divide both sides by 10

[tex]100 = l * w[/tex]

Reorder

[tex]l * w = 100[/tex]

This implies that when the value of l and w are multiplied together, the result is always 100.

Possible values of (l,w) are: (100,1) (50,2) (25,4) (20,5) (10,10) and many more

Answer:

640

Step-by-step explanation:

200 divided by 25 = 8

which means Kris can run 8 meters per second. 8 times 80 equals 640.

[tex]\frac{641}{1000}[/tex]  If you read the decimal and the fraction, it both reads 651 thousandths. So, therefore this is the correct answer

Answer:

651/1000

Step-by-step explanation:

The decimal reads 651 thousandths so 651 would be your numerator and 1000 would be your denominator. The fraction is not reduceable.

Answer:

= 45 miles per hour

Step-by-step explanation:

First, we want a unit rate where 1 is in the denominator.

So we divide,

180 miles/ 4 hours both ÷ by 4

= 45 miles/ 1 hour

= 45 miles/ hour

= 45 miles per hour

Answer:

A. y = 5/4x - 3

B. slope is 5/4

C. y intercept is -3

D. Increasing

Step-by-step explanation:

5x - 4y = 12

Slope intercept form: y = mx + b

4y = 5x - 12

y = 5/4x - 3

Slope is 5/4

Y intercept is when x = 0 so it is -3

the slope is positive, therefore the line is increasing

Answer:

a = [tex]\frac{b-bc}{d}[/tex]

Step-by-step explanation:

Given

bc + ad = b ( subtract bc from both sides )

ad = b - bc ( isolate a by dividing both sides by d )

a = [tex]\frac{b-bc}{d}[/tex]

Answer:

The answer is D, x - 3.

Step-by-step explanation:

If we factor x^3-3x^2, the result is x^2(x-3).

Answer:

D

Step-by-step explanation:

Given

x³ - 3x² ← factor out x² from each term

= x²(x - 3) ← in factored form

with one of the factors being x - 3 → D

Answer:

B , D , A ,C

Step-by-step explanation:

PEMDAS

Answer:

= 5² = 25

= 36 ÷ 6 = 6

= 6 × 3 = 18

= 18 + 25 = 43

Step-by-step explanation:

The order of operations is PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction From Left to Right.

First is Exponents.

5² = 5×5 = 25

From left to right, division comes first.

36 ÷ 6 = 6

Then multiplication.

6 × 3 = 18

Lastly, addition.

18 + 25 = 43

Hope that helps.

Answer: true i believe

Step-by-step explanation:

Answer:

B(2,10)

D'(4,-1)

Step-by-step explanation:

ok to find this we need to know what the translation is

from (2,2) to (-4,-1)

subtract 6 from x and subtract 3 from y

im gonna chak another just in case

3rd one

(10,10) to (4,7)

same rule

so for the second one they give us (-4,7)

to get this we subtracted 6 from x and 3 from y from original so

lets work backwards

add 6 from x and add 3 from y

(-4,7)+(6,3)

answer(2,10)

now D'

subtract 6 from x and 3 from y

(10,2)-(6,3)

(4,-1)
