Answer:

y = -2x + 28

Step-by-step explanation:

We are given the slope and a point on the line so first we use the point-slope form :-

y - y1 = m(x - x1)

Substituting the given values:-

y - 12 = -2(x - 8)

Now convert to the slope-intercept form (which is y = mx + c):-

y = -2x + 16 + 12

y = -2x + 28 (answer)

Answers for the 2 boxes please:)

Answer:

(5,-5)

Step-by-step explanation:

Eliminate y-term

$(2x + 5x) + ( - 3y + 3y) = 25 + 10 \\ 7x = 35 \\ x = \frac{35}{7} \\ x = 5$

We can eliminate x-term but for this system of equations, eliminating y-term is faster.

Substitute x = 5 in any given equations.

I will choose to substitute in the first equation.

$2x - 3y = 25 \\ 2(5) - 3y = 25 \\ 10 - 3y = 25 \\ 10 - 25 = 3y \\ - 1 5 = 3y \\ 3y = - 15 \\ y = - 5$

Answer Check

Substitute both x-value and y-value in any given equations

$2x - 3y = 25 \\ 2(5) - 3( - 5) = 25 \\ 10 + 15 = 25 \\ 25 = 25$

The equation is true. (It is better to check both the answer for both equation.)

Thus the answer is (5,-5)

Calculat the length of the circumference of a circle with diameter of 8cm.

mr_godi [17]

Hello there!

The formula for finding the circumference of a circle is 2 $\pi$ r (or 2*3*r in your terms). Although we don't have the radius yet, we can certainly find it pretty easily. Keep in mind that the radius will always be half the diameter. So, let's find the radius.

8 / 2 = 4; now we have everything we need to solve for the circumference.

2*3*4 is our expression. Now let's simplify it.
2 * 3 = 6
6 * 4 = 24

Your circumference is 24cm.

I hope this helps!

Evaluate 13 + 6 y 13+ y 6 13, plus, start fraction, 6, divided by, y, end fraction when y = 6 y=6y, equals, 6.

Lubov Fominskaja [6]

Answer:

The answer is 14

Step-by-step explanation:

Evaluate 13 + 6/ y when y = 6

We substitute 6 for y in the above expression

= 13 + 6/6

= 13 + 1

= 14

The answer to the the above question is 14

Use the Pythagorean theorem to solve this problem. William walks 3.0 miles south and then turns and walks 4.0 miles west. What i

AnnyKZ [126]

Since south and west are at 90 degree angle that means we can use pythagorean theorem to find the distance.

It goes like this:
c^2 = a^2 + b^2

a = 3
b = 4

implementing this in pythagoras formula we get that c = 5

answer is 5 miles southwest
