40)Find the slope of the line containing the points (5, -1) and (-8, -4).
A. 313
B. 133
C. −53
D. 53

Answer:

use the slope equation (y2-y1) / (x2 -x1). plug in values and solve

(-1 -7) / (9 -(-3)) (subtracting a negative is the same as adding a positive)

-8 / 12 (simplify)

m = -2/3

then, plug in one of the points and the slope into the slope-point equation.

(y - y1) = m (x - x1) (the point-slope form)

y - 7 = -2/3( x - (-3)) (plug in the slope and point 1 values, then solve)

y - 7 = -2/3x - 2 (add 7 to both sides)

y = 2/3x +5 (the answer)

Answer:

The expression to find the perimeter is [tex]12x^2-6[/tex].

Step-by-step explanation:

Given: The side lengths of the triangle are [tex](4x^2-3)[/tex] inches, [tex](4x^2-2)[/tex] inches, and [tex](4x^2-1)[/tex] inches.

To find: The expression that can be used to find the perimeter of the triangle.

Solution:

We have,

The side lengths of the triangle are [tex](4x^2-3)[/tex] inches, [tex](4x^2-2)[/tex] inches, and [tex](4x^2-1)[/tex] inches.

We know that,

The perimeter of a triangle is sum of all the sides.

So, Perimeter [tex]=(4x^2-3)+(4x^2-2)+(4x^2-1)[/tex]

[tex]\implies \text{Perimeter}=12x^2-6[/tex]

Hence, the expression to find the perimeter is [tex]12x^2-6[/tex].

Answer:

To make 6 cups, you will need 2 cups of lemon and 4 cups of water....6 total

TWO of the six are lemon    2/6 x 100 = 33.33% Lemon    the rest is water  100-33.33= 66.67% water

OR

FOUR out of the SIX are water    4/6 x 100 = 66.67% Water

Step-by-step explanation:

Answer: The new container folds 100 fluid ounces.

Step-by-step explanation:

Given: A company claims that their new bottle holds 25% more laundry soap.

If original container hold 80 fluid ounces.

Then, Quantity of soap in the new container = 80 fluid ounces + 25% of 80 fluid ounces

= [80+0.25 x 800]  fluid ounces               [ 25% = 0.25]

= 80+ 20= 100 fluid ounces  

Hence, the new container folds 100 fluid ounces.

Answer:

B

Step-by-step explanation:

the way to find the answer is the number/total

number is 8 cuz there are 8 orange balloons

total is 22+7+8+13=50

therefore 8/50 = 4/25

Step-by-step explanation:

36 plus 4 x 2 = 80 what her mom got but it’s 76 because 36x2 is 72 and 72 plus 4 is 76.

We can say that the y intercept is at the location (0,-1)

This is where the graph crosses the vertical y axis. This is 1 unit below the origin.

This is assuming each tickmark on the grid represents 1 unit.

Answer:

The y- intercept is (0,-1)

Step-by-step explanation:

A y- intercept is when a point intercepts (crosses) the y- axis. Since the dot does not cross the x- axis, that point will be 0. It is below the y- axis, meaning it will be -1.

Answer:

The value of x = 13.7.

Step-by-step explanation:

Given

Hypotenuse = c = 16.5

a = 9.2

To determine

x = b ?

For a right-angled triangle with sides a, and b the hypotenuse is defined as

[tex]c=\sqrt{a^2+b^2}[/tex]

In our case, we have to get x

[tex]b=\sqrt{c^2-a^2}[/tex]

so substituting b = x, c = 16.5, a = 9.2

[tex]x=\sqrt{16.5^2-9.2^2}[/tex]

[tex]x=13.7[/tex]

Therefore, the value of x = 13.7.

Answer:

this is a required equation.

32+40+13=85

Answer:

about $26.00

Step-by-step explanation:

$25/100 = 0.25 for 1%

1% times 4.1 = 1.025 in sales tax

plus 25 equals 26.025

round to the nearest cent = $26.00

Step-by-step explanation:

60+30=90

180-90=90

60+30+90=180

so the x is 90

Answer:

x=3.5 if rounded if not than 3.4

Step-by-step explanation:

Answer:

a). x = 10.20 in

b). x = 2.24

Step-by-step explanation:

a). By applying Pythagoras theorem in the given right angle,

    (Hypotenuse)² = (Leg 1)² + (Leg 2)²

    (15)² = x² + (11)²

     225 = x² + 121

     x² = 225 - 121

     x² = 104

     x = √104

     x = 10.198 ≈ 10.20 in

b). By applying Pythagoras theorem,

    (3x)² = (2x)² + (5)²

     9x² = 4x² + 25

     9x² - 4x² = 25

     5x² = 25

      x² = 5

    x = √5 = 2.24

Answer:

9x - 2y = 0

Step-by-step explanation:

Given

x - 3y = 6 → (1)

- 8x - y = 6 → (2)

Subtracting (2) from (1) term by term gives

x - (- 8y) - 3y - (- y) = 6 - 6 , that is

x + 8y - 3y + y = 0

9x - 2y = 0

Answer:

The domain is all real number:

i.e.

[tex]-\infty \:<x<\infty \:[/tex]

Therefore,

[tex]\mathrm{Domain\:of\:}\:10^x\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:<x<\infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}[/tex]

Step-by-step explanation:

Given the function

y = 10ˣ

Determining the domain of the function y = 10ˣ :

We know that the domain of the function is the set of input or arguments for which the function is real and defined.  

In other words,

From the graph, it is clear that the function has no undefine points nor domain constraints.

Thus, the domain is all real number:

i.e.

[tex]-\infty \:<x<\infty \:[/tex]

Therefore,

[tex]\mathrm{Domain\:of\:}\:10^x\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:<x<\infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}[/tex]
