Answer 2

Answer:

4y+9

Step-by-step explanation:

To find the perimeter , you have to add up all the 4 sides

PROBLEM SOLVING Find the value of k so that the graph of the equation has the given y-intercept.
y = -1/3x + 5/6k; b = - 10

K=?

Answers

Answer:

2k⋅(3k−7)⋅(k+4)

Step-by-step explanation:

STEP

Equation at the end of step 1

((6 • (k3)) + (2•5k2)) - 56k

STEP

Equation at the end of step

((2•3k3) + (2•5k2)) - 56k

STEP

Pulling out like terms

4.1 Pull out like factors :

6k3 + 10k2 - 56k = 2k • (3k2 + 5k - 28)

Trying to factor by splitting the middle term

4.2 Factoring 3k2 + 5k - 28

The first term is, 3k2 its coefficient is 3 .

The middle term is, +5k its coefficient is 5 .

The last term, "the constant", is -28

Step-1 : Multiply the coefficient of the first term by the constant 3 • -28 = -84

Step-2 : Find two factors of -84 whose sum equals the coefficient of the middle term, which is 5 .

-84 + 1 = -83

-42 + 2 = -40

-28 + 3 = -25

-21 + 4 = -17

-14 + 6 = -8

-12 + 7 = -5

-7 + 12 = 5 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -7 and 12

3k2 - 7k + 12k - 28

Step-4 : Add up the first 2 terms, pulling out like factors :

k • (3k-7)

Add up the last 2 terms, pulling out common factors :

4 • (3k-7)

Step-5 : Add up the four terms of step 4 :

(k+4) • (3k-7)

Which is the desired factorization

Final result :

2k • (3k - 7) • (k + 4)

we know that

- x+y=27, Which is equation A.

- x/y = 5/4

- isolate the variable y

- y=4/5x, Which is equation B.

- 9/5x=27

Trey deposits $8000 into an account that pays simple interest at a rate of 5% per year. How much interest will he be paid in the first 4 years
6

Answers

Answer:

1600

Step-by-step explanation:

You want to calculate the interest on $8000 at 5% interest per year after 4 year(s).

The formula we'll use for this is the simple interest formula, or:

Where:

P is the principal amount, $8000.00.

r is the interest rate, 5% per year, or in decimal form, 5/100=0.05.

t is the time involved, 4....year(s) time periods.

So, t is 4....year time periods.

To find the simple interest, we multiply 8000 × 0.05 × 4 to get that:

The interest is: $1600.00

Usually now, the interest is added onto the principal to figure some new amount after 4 year(s),

or 8000.00 + 1600.00 = 9600.00. For example:

If you borrowed the $8000.00, you would now owe $9600.00

If you loaned someone $8000.00, you would now be due $9600.00

If owned something, like a $8000.00 bond, it would be worth $9600.00 now.

the volume of a cube is 125m find it's side

Answers

Answer:

Using reflection concepts, it is found that the correct option is:

What is the equation of the line that passes through the point (5,6) and has a slope of 2 ?

Answers

Answer:

y = 2x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2, thus

y = 2x + c ← is the partial equation

To find c substitute (5, 6) into the partial equation

6 = 10 + c ⇒ c = 6 - 10 = - 4

y = 2x - 4 ← equation of line

Alex and Freddy collect stamps. The number of stamps in Alex’s collection is in ratio 3:5 to the number of stamps in Freddy’s collection. If Freddy gives Alex 10 stamps, the ratio will change to 7:9. How many stamps are in both collections together?

Answers

suppose Alex has 3x stamps, Freddy has 5x stamps. After Freddy gives Alex 10 stamps, Alex has 3x+10 while Freddy has 5x-10
the new ratio is 7 to 9, so we have the equation: (3x+10)/(5x-10)=7/9
9(3x+10)=7(5x-10)
27x+90=35x-70
160=8x
x=20
So Alex has 3*20=60 stamps while Freddy has 5*20=100. Together they have 160

Find the Error A student graphs the relationship y = x on a coordinate plane. She says the slope is O because there is no coefficient. Find her
mistake and correct it.

Answers

Answer:

y=x times factor of 12 abstracted by -93

Step-by-step explanation:

The slope is the ratio of y's coordinate to x's coordinate thus the slope of y = x will be y/x = 1.

What is the slope?

A slope is a tangent or angle at a point or a slope is the intensity of inclination of any geometrical lines.

Slope = Tanx where x will be the angle from the positive x-axis at that point.

A linear equation or function is given as ;

y = mx + b

Now,

At x = 0 ⇒ y = b so it will be a y-intercept.

As per the given, y = x

The x's coefficient is 1 thus slope will be 1.

Or, y/x = 1

Hence "The slope is the ratio of y's coordinate to x's coordinate thus the slope of y = x will be y/x = 1".
