Answer: The solution for the system is (2, -7)

Step-by-step explanation:

Ok, here we have linear relationships.

A linear relationship can be written as:

y = a*x + b

where a is the slope and b is the y-axis intercept.

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1).

In this case, we have two lines:

ya, that passes through:

(-8, -5) and (-3, -6)

Then the slope is:

a = (-6 - (-5))/(-3 - (-8)) = (-6 + 5)/(-3 + 8) = -1/5

now, knowing one of the points like (-3, - 6) we can find the value of b.

y(x) = (-1/5)*x + b

y(-3) = -6 = (-1/5)*-3 + b

-6 = 3/5 + b

b = -6 - 3/5 = -33/5

then the first line is:

ya =  (-1/5)*x  -33/5

For the second line, we know that it passes through the points:

(-8, -15) and (-3, -11)

Then the slope is:

a = (-11 - (-15))/(-3 -(-8)) = (-11 + 15)/(-3 + 8) = 4/5

The our line is:

y(x) = (4/5)*x + b

and for b, we do the same as above, using one of the points, for example (-3, -11)

y(-3) = -11 = (4/5)*-3 + b

b = -11 + 12/5 = -(55 + 12)/5 = -43/5

then:

yb = (4/5)*x - 43/5.

Ok, our system of equations is:

ya = (-1/5)*x  -33/5

yb = (4/5)*x - 43/5.

To solve this, we suppose ya = yb

then:

(-1/5)*x + -33/5 = (4/5)*x - 43/5.

-33/5 + 43/5 = (4/5)*x + (1/5)*x

10/5 = 2 = (4/5 + 1/5)*x = x

2 = x

now we evaluate x = 2 in one of the lines:

ya = (-1/5)*2 -33/5 = -2/5 - 33/5 = -35/5 = -7

Then the lines intersect at the point (2, - 7), which is the solution for the system.

Answer:

4.08

Step-by-step explanation:

3 2/5 ÷ 5/6

(3 x 5) + 2 = 17/5

Flip 5/6 to 6/5

Turn division sign to multiplication.

17/5 x 6/5 = 102/25

102 ÷ 25 = 4.08

Hope this helped.

Answer:

1/(12^2)

Step-by-step explanation:

12^ -7 × 12^5

= 12^-7+5

= 12^5+(-7)

= 12^5-7

= 12^-2

= 1/(12^2)

Answer:

120 blocks total

Step-by-step explanation:

All of the little cubes have side length 2"  Thus, the 11" height of the box cannot be used entirely:  we waste the top 1" because the five layers of little cubes reach only to 10" from the bottom.

Start at the bottom of the box.  The dimensions of the bottom are 12" by 8".  Along the longer side we can lay 6 blocks (which add up to 12" and are 2" wide.  We can add 3 more such rows to fill the available 8" width of the box bottom.  That's 6*4, or 24 blocks.

We can add 4 more 6 block by 4 block layers before we have the maximum 5 layers stacked in the box.

5 layers times 24 blocks per layer comes to 120 blocks total.

Answer:

x=15/8; x ≈ 1.88

Step-by-step explanation:

cross products

15=8x

Divide both sides by 8

x = 1.875 = 15/8

x ≈ 1.88

Step-by-step explanation:

I’m pretty sure the answer should be 1,710 if not i’m sorry

Answer:

1710 fish

Step-by-step explanation:

Let the number of fish in the lake last year be 'x'

The equation becomes-
x + 15x/100=6210     (This is because 15% of x is added in x to become    
6210... hope you understand)

x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400

Therefore- The number of fish last year = 5400


Now, let the number of fish in the lake 2 years ago be 'y'

The equation becomes-
y + 20y/100 = 5400     (Same logic as last time)

y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500

Therefore- Fish in the lake two years ago = 4500 fish

Difference between current and two years ago = 6210-4500
                                                                               = 1710 fish

Hope you understood the answer and I hope it helps you :)

Answer:

10976

Step-by-step explanation:

First lets start off by finding out how many cats there are (not kittens).

There were 7 girls, with 7 bags each, which contained 7 cats.

That turns into 7^3 or 7 * 7 * 7

7^3 = 343 cats

343 cats * 4 legs = 1372 legs (keep this for later).

Now you must find out how many kittens there are.

343 cats with 7 kittens each = 343 * 7

2401 kittens * 4 legs = 9604 legs

Now you must bring in the legs of the cats and kittens and add them together.

1372 legs (cats) + 9604 legs (kittens) = 10976 legs (total)

I hope it helps......:))

Answer:

-16, 10, 16, 25, 43

Step-by-step explanation

when you have something in absolute value bars it's always going to be positive so you would make -16 regular 16; and 10 stays 10; 25 stays 25; -16 stays - 16; and then -43 turns into regular 43

Answer:

-16, 10, 16, 25, 43

Step-by-step explanation:

If it has the bars around it and its a negative number  it turns into a posotive

Answer:

9

Step-by-step explanation:

Coefficient is a number that is being multiplied by the variable.

Step-by-step explanation:

(12, -11) represents (x, y)

so 12 is x

-11 is y

now we need to do

x-9 and y+9

x-9=

12 - 9 = ???

y+9=

-11 + 9 = ???

then put into formate (x, y) as before

if you need more help comment and please put as brainiest

Answer:

(3, -2)

Step-by-step explanation:

(x - 9, y + 9)

plug 12 for x, plug -11 for y

(12 - 9, -11 + 9)

(3, -2)

Answer:

no triangle

Step-by-step explanation:

The sum of the measures of a triangle is 180°.

70° + 85° + 105° = 260°

Since the sum of the given measures is 260°, no triangle with these angle measures can be constructed since it cannot exist.

Answer:

36.85 ft

Step-by-step explanation:

3 feet on either end + 6 feet on either side + circumference of the circle

3 + 3 + 6 + 6 + circumference of the circle

18 + circumference of the circle

You can find the circle's diameter by subtracting 6 from 12.  You get 6.  You can find the radius by dividing the diameter by 2.  You get 3.

The formula for circumference is 2·π·Radius

2 · π · 3 = 6 · π = 6 · 3.14 ≈ 36.85
