Step-by-step explanation:

by inspection.. ( looking at the graph)  we can see that the slope is down hill. so it's going to be negative and also  slope = rise / run     [rise is negative in this question] soo ... i'm looking carefully to see where the line is crossing the grid marks exactly .. it looks like to me  (-3,1) and (2,-3)   you tell me if that looks right... if it does .. then the rise / run is 4/5  and this is a negative slope  sooo

Answer: 14

Step-by-step explanation: The perimeter is all of the side added together. When finding the perimeter of a rectangle the opposing sides have the same value. So the equation would be 2(12) + 2(a) = 52. 12 x 2 is 24. 52- 24 is 28 and youre left with 28 = 2(a). You divide each side by 2 and get 14 = a

Answer:

y = 4.25x

Step-by-step explanation:

Given that:

After 2 week he has used 8 1/2 cups of dog food after 5 week he has used 21 1/4 cups, we can write this in coordinate form (x, y) where;

y is the amount of dog food

x is the time in weeks

The coordinates are (2, 8 1/2) and (5, 21 1/4)

get the slope m:

m = y2-y1/x2-x1

m = (21 1/4 - 8 1/2)/5-2

m = (85/4-17/2)/3

m = (85-34/4)/3

m = 51/12

m = 4.25

Get the intercept c:

Substitute any of the points say (2, 17/2) and m = 51/12 into the equation

y = mx+c

17/2 = 51/12(2) + c

17/2 = 51/6 + c

c = 17/2 - 51/6

c = 51-51/6

c = 0

Get the required equation:

substitute m - 4.25 and c = 0 into y = mx+c

y = 4.25x + 0

Hence the required equation is y = 4.25x

Answer:

819

Step-by-step explanation:

We solve the above question using simple interest

The formula for the total amount in a bank amount when it earn simple interest annually is:

A = P(1 + rt)

When

P = Initial amount in the account = 780

r = Simple Interest rate = 2.5% = 0.025

t = 2 years

A = 780(1 + 0.025 × 2)

A = 780(1 + 0.050)

A = 780(1 .050)

A = 819.00

The amount of money that will be in her account if she does not make any deposits or withdrawals in 2 years is 819.

Answer:

n = - [tex]\frac{4}{3}[/tex]

Step-by-step explanation:

Given

- 5(n - 1) = 7(n + 3) ← distribute parenthesis on both sides

- 5n + 5 = 7n + 21 ( subtract 7n from both sides )

- 12n + 5 = 21 ( subtract 5 from both sides )

- 12n = 16 ( divide both sides by - 12 )

n = [tex]\frac{16}{-12}[/tex] = - [tex]\frac{4}{3}[/tex]

Answer:

Step-by-step explanation:

To solve this you have to use the distributive property.

So first you would distribute the -5 to n and -1.

So the new equation will be -5n + 1 = 7 (n + 3)

Next, distribute the 7 to n and 3.

The new equation will be -5n + 1 = 7n + 21

Next you simplify by adding 5n to both sides which will give you 1 = 12n + 21

Then you subtract 21 from both sides and get -20 = 12n

So then you divide both sides by 12 to get n by itself and you are left with  -5/3 = n

Answer:

47

Step-by-step explanation:

The cost of beginner classes is $7.6 and the cost of the advanced classes is $29.2

Addition, subtraction, multiplication, and division are the four basic algebraic operations.

Given that, x is the cost of beginner classes, and y is the cost of advanced classes.

The relationship between beginner classes and advanced classes is

x=0.5y-7

4x+3y=118

From the first equation, we can write

y=2x+14

Using this equation, we can write

4x+3(2x+14) =118

10x+42=118

i.e x=7.6

Substituting the value of x in the equation y=2x+14, we get

y=(2*7.6)+14

i.e y=29.2

The cost of beginner classes is $7.6, and the cost of advanced classes is $29.2.

Cos(x)=Adj/ Hyp

Hyp*Cos(45) = Adj

26 * [tex]\sqrt{2}/2\\[/tex] = Adj

13[tex]\sqrt{2}[/tex]  both legs

Step-by-step explanation:

So, we will take one of the numbers = x

And the other is 12 more than 3 times it, so = 3x + 12

So they said if we add them, we will get 4

So x + (3x + 12) = 4

4x + 12 = 4

4x = 4 - 12

4x = - 8

x = - 8 ÷4

x = - 2

So one of the numbers x = - 2

The other is 3x + 12

So x = - 2

3x +12 = 3(-2) + 12

= 6

So the 2 numbers = 6 and - 2

Lets check!

6 + (-2) = 4

So it's right!

Step 1: Subtract [tex]p[/tex] from both sides of the equation.

Step 2: Factor out the common term [tex]y[/tex] from the left side

Step 3: Divide both sides by [tex]t-q[/tex]
