Write the equation for the line that goes through point (1, 1) with slope m = -9

1 answer:

7 0

1) Since we have the slope, and one point we can find that linear equation using this point-slope formula. Plugging them we have:

$\begin{gathered} (y-y_0)=m(x-x_0) \\ y-1=-9(x-1) \\ y-1=-9x+9 \\ y=-9x+9+1 \\ y=-9x+10 \end{gathered}$

2) Note that we had to add 1 to both sides, to keep the "y "on the left.

3) Therefore, y=-9x+10 is the answer.

Rewrite this radicand as two factors, one of which is a perfect square.

seropon [69]

Answer:

$2 \sqrt{15}$

Step-by-step explanation:

1) rewrite 60 as it's prime factors.

$\sqrt{2 \times 2 \times 3 \times } 5$

2) group the smae prime factors into pairs.

$\sqrt{(2 \times 2)} \times 3 \times 5$

3) Rewrite each pair in exponent form.

$\sqrt{ {2}^{2} \times 3 \times 5 }$

4) use this role:

$\sqrt{ {x}^{2} } = x$

$2 \sqrt{3 \times 5}$

5) Simplify.

$4 \sqrt{15}$

So, therefor, the answer is option 1.

David's score on his fifth test would be an 87. If you add up all the scores from his first to his fourth test, it would 363. However, since there are five tests, in order to get a 90 percent, the sum of all five test scores would be 450. 450 - 363 = 87.

Hey there look like you need some help.
If I give you the correct answer mark me brainleist

First you would find the area of the square: 230*230= 52,900Next you would find the area of one on the triangles: 230*187=43,010 * 1/2= 21,505Then you would multiply the area of the one triangle by four: 21,505*4= 86,020Finally, you would add the area of the square to the combined area of the triangles: 86,020+ 52,900=138,920
