This means that each book cost $18

Find the solution of the system of equations.
3x+3y= −6
10x+3y= −13

Answers

Answer:

x=−1, y=−1

Step-by-step explanation:

Solve for x in the first equation.

x=−2−y

10x+3y=−13

Replace all occurrences of x with −2−y in each equation.

−20−7y=−13

x=−2−y

Solve for y in the first equation.

y=−1

x=−2−y

Replace all occurrences of y with −1 in each equation.

x=−1, y=−1

8a The following three shapes are based only on squares, semi circles, and quarter circles. find the perimeter and the area of each shaded parts. Give your answers as completely simplified exact value in terms of pi (no approximations). I NEED THE ANSWER NOW, FIND AREA.

Answers

Answer:

Step-by-step explanation:

The area is 32[tex]\pi[/tex]-64cm^2

if you look at it, ADC makes a quarter circle and so does ABC, so:

area of a circle:[tex]\pi[/tex]r^2 so

then since it’s a quarter circle, divide by 4 which gives you 16[tex]\pi[/tex]

and since there are 2 quarter circles 16[tex]\pi[/tex](2) gives you 32

then you find the area of the square: 8(8) gives you 64 so to find shaded area subtract 64 from 32[tex]\pi[/tex] and that’s the answer

Please show all work :)

Answers

I might be wrong but I think the answer would be -x+2x+6 as a simplified version because if you use the equation (x+4•x+3)-3x(x+1)=a (or any letter you choose), you will get 3x+x^2+12+4x-3x-3x^2=y. Then, you can combine like terms:
4x-2x+12=a

Answer:

y = 1/2x + 1

Step-by-step explanation:

Slope intercept form is writen as [ y = mx + b ], where m = slope and b = y-intercept.

We are already given the y-intercept which is 1. We just need to find the slope and we can do this by using the formula [ y2-y1/x2-x1 ].

3-1/4-0

2/4

1/2

Now, put everything we have into the formula.

y = 1/2x + 1

Combine Like Terms : 4x-8-8

Answers

Answer:

4x-16

Step-by-step explanation:

When combining like terms you combine the constant terms (the terms without a variable) and the x terms. Since the only variable term is 4x we can leave in at that.

But there are two constant terms -8 and -8, together they make -16 so, the simplified expression would be 4x-16

6 m from the pole from base of a telephone pole and 10 m to reach the top of the pole how tall is the telephone pole

Answers

Answer:

Explanation

The set up is a right triangle

Given

The distance of pole from the base = 6m

Length of the pole = 10m

Required

Height of the telephone pole h

Using the pythagoras theorem;

hyp^2 = opp^2 + adj*2

10^2 = 6^2 + h^2

h^2 = 10^2 - 6^2

h^2 = 100 - 36

h^2 = 64

h = √64

h = 8m

Hence the height of the telephone pole is 8m

An investor has an account with stock from two different companies. Last year, her stock in Company A was worth $3160 and her stock in Company B was worth $5800. The stock in Company A has increased 20% since last year and the stock in Company B has increased 4%. What was the total percentage increase in the investor's stock account? Round your answer to the nearest tenth (if necessary).

Answers

Answer:

109.6%

Step-by-step explanation:

Last year:

Company A stock + Company B stock = total amount of stock:

$3160 + $5800 = $8960

This year:

Company A stock: $3160 + ($3160*0.20) = $3792

Company B stock: $5800 + (5800*0.04) = $6032

Company A stock + Company B stock = total amount of stock:

$3792 + $6032 = $9824

Total amount of increase from last year:

(9824/8960)*100 = 109.6 percent
