x^y × x^3 = 1/(x^2) = x^(-2)

that means

y + 3 = -2

y = -5

the missing exponent is -5

Hi Ashley,    this looks harder than it really is  :)

recall your powers rules

so  [tex]x^{2}[/tex]  *  [tex]x^{2}[/tex] = [tex]x^{2+2}[/tex]=[tex]x^{4}[/tex]

knowing that you can probably figure this out.  But I'll help anyway

[tex]x^{?+3}[/tex] = 1 / [tex]x^{2}[/tex]

now flip over the fraction to make this even easier

[tex]x^{?+3}[/tex] = [tex]x^{-2}[/tex]

ohhhh  I bet you can see it now, huh

we just need  3 plus something to equal -2

that's negative 5 ,  right???

[tex]x^{-5+3}[/tex] = [tex]x^{-2}[/tex]

ahh, nice  , now just break it back up

[tex]x^{-5}[/tex] * [tex]x^{3}[/tex] = 1 / [tex]x^{2}[/tex]

got it???

Nick will write

Date i.e. 11/5/20XX, Description i.e. Pay James, Check Number i.e. 123, Debit i.e. $150.32, Balance i.e. $X - $150.32.

The New balance will be $X - $150.32, where $X is the previous balance.

Given, that Nick writes a check to his friend James Sloan for $150.32 on May 11.

Let suppose Nick had an 'X' amount in his bank account.

He will fill the check register like this

Date           Description       Check Number       Debit       Credit     Balance

11/5/20XX                                                                                                $X

11/5/20XX   Pay James              123                  $150.32              $X-$150.32

Hence, Nick will write

Date i.e. 11/5/20XX

Description i.e. Pay James

Check Number i.e. 123

Debit i.e. $150.32

Balance i.e. $X - $150.32

The New balance will be $X - $150.32 i.e. $150.32 subtracted from the previous balance.

Since Kelly chooses one tile, places it back in the box, and then choose another tile, we have that the total outcomes are 4x4 = 16.

Now, we can write easily all the outcomes :

notice that on the first row, only the event (8,1) gives us that the sum is greater than 7.

On the second row,we have the same for events (4,4),(5,4) and (8,4)

On the third row only (1,5) gives us a sum lesser than 7, then here we have 3 more events that fit our criteria.

On the last row, all events gives us a sum greater than 7,then we have another 4 events.

Answer:

x = -5

Step-by-step explanation:

    x - 3(x + 2)= 4

    x - 3x - 3*2 = 4     {Distributive property}

   x - 3x  - 6    = 4

Combine like terms in LHS,

Add 6 to both sides,

The formula for the monthly loan payment is given as

Where

P = loan amount ( initial principal) = $15000

A= Payment amount per period = ?

r = interest rate per period = (5/12) x (1/100) =0.0041667

n = total number of payments or periods = 4 years = 4 x 12 = 48 months

Substituting all these into the above equation gives

So each month he pays $345.44 to the nearest cent

B)

The total interest for the loan is given by

Total amount paid over the total period of time - Original amount borrowed

Total amount paid over the total period of time = 345.44 x 48 months = $16581.12

The total interest of the loan hence = $16,581.12 - $15,000 = $1,581.12

The total loan interest to the nearest cent = $1,581.12

The equation 154 = -4(8+6r) + 24r has no solution because the variable becomes 0.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

We have to find the variable r of the equation to solve the equation.

A variable is a number represented with letters in an equation.

Therefore, let's find the variable r in the equation.

154 = -4(8+6r) + 24r

open the brackets on the right side of the equation

154 = - 32 - 24r + 24r

154 = -32 + 0

Therefore, the equation cannot be solved.

A slope triangle is a hypothetical triangle that aids in determining a line's or line segment's slope.

The line whose slope you are interested in learning is the triangle's hypotenuse (the diagonal). The slope formula's "rise" and "run" values are the two "legs" of the triangle.

Answer:

(3, -4)

Step-by-step explanation:

To solve the system of equations by substitution, start by labelling the 2 given information.

y = x - 7 -----(1)

5x + 2y = 7 -----(2)

Substitute (1) into (2):

5x + 2(x - 7) = 7

Expand:

5x + 2x - 14= 7

7x = 14 + 7

7x = 21

Divide both sides by 7:

x = 21 ÷ 7

x = 3

Substitute into (1):

y = 3 - 7

y = -4

Answer: 3rd one is correct

Step-by-step explanation: got it right on the test

About 3 full cones of water are needed to be added to the cylinder to completely fill it.

The radius of the right circular cone is 3cm and the slant height is 5 cm.

The height of the cone can be found as,

H = √(5)²- (3)²

H = 4cm

The volume of the cone is given by,

V = πR²H/3

R is the radius and H is the height of the cone,

Putting values,

v = π x 5 x 5 x 4/3

v = 104.71 cm³

Now, the height h of cylinder is given to be 6 cm and the radius r of the cylinder is 4cm.

The volume of the cylinder is given as,

V = πr²h

V = π x 4 x 4 x 6

V = 301.59

Let us assume that we have to add n full cones of water to completely fill the cylinder, so, we can write,

nv = V

Putting values,

n104.71 = 301.59

n = 2.85

So, we have to add roughly three full cones of water to completely fill the cylinder.

Volume of the cylinder = πr²h

see explanation below

A cylinder comprises of two circles and a curved part.

To get the volume, we would multiply the area of the circle with the height of the cylinder

The height of the cylinder is the distance between the two circular ends

Area of a cirlce is pi multiplied by radius squared

Area of circle = π×r² = πr²

where r = radius

h = height of the cylinder

Volume of the cylinder becomes = πr² × h

Volume of the cylinder = πr²h

Answer:

Top: y = x

Bottom: y = 0.8x - 3.2

Step-by-step explanation:

I can see the question is asking to write the equation in Slope-Intercept form.

Slope-Intercept Form:

y = mx+b

M is the slope or how much the y value increases every time the x value increases by one. b is the y-intercept or when x=0.

Because these lines are parallel, we know they have the same form.

Lets look at the top line. When x increases by one, how much does y increase by?

1

What is the y value of when the line's x-value is 0?

0

Now, we have,

y = 1x + 0

Because adding 0 keeps the equation the same, we can remove it.

y = 1x

Because multiplying a term by 1 leaves it the same, we can remove one.

y = x

Now, for the bottom line.

How much does y increase by when x increases by 1? Because the slope will be a fraction and is not easy to see, I will use the slope formula.

Slope Formula:

[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

To find the slope, take any pair of points on the line and plug them in.

I'll use:

(0,-3.2)

(4,0)

Plug the y-values (the latter number, or the height of the point) into the formula. Do the same with the x-values. keep in mind it does not matter what y-value you plug in. For example, for [tex]y_2[/tex] and [tex]y_1[/tex] you can plug in -3.2 and 0 or vice versa. If you make [tex]y_2[/tex] -3.2, then make [tex]x_{2}[/tex] 0.

[tex]\frac{-3.2-0}{0-4}[/tex]

Simplify.

[tex]\frac{-3.2}{-4}[/tex]

Because a negative number multiplied or divided by another negative number is always a positive number, remove the negative signs.

[tex]\frac{3.2}{4}[/tex]

Divide.

3.2/4 = 0.8

Now we have m, the slope on the 2nd line, 0.8

y = 0.8x + b

What is the y-value of the line when the line has the x-value of 0? On the graph, it says -3.2.

y = 0.8x - 3.2

Let the three consecutive even number be,

x, x+2, x+4

Sum of the numbers is 1002.

Hence, the numbers are,

332, 332+2, 332+4

Hence, the answer is 332, 334, 336.

The solution to the fraction two and one-third times four-fifths equals one and thirteen-fifteenths.

The correct answer option is option C

A fraction refers to a part of a whole, especially a comparatively small part. It is also the ratio of two numbers, the numerator and the denominator, usually written as one above the other and separated by a horizontal bar.

A numerator is the number above the horizontal bar while the denominator is the number below the horizontal bar in a fraction.

Two and one-third times four-fifths

= 2 1/3 × 4/5

= 7/3 × 4/5

= (7 × 4) / (3 × 5)

= 28 / 15

= 1 13/15
