Answer:

1) y = - 5/3x

2) y = - 4/3x

3) slope = - 1/17

4) slope = 6

6) y = -x - 1

7) y = -3/5x - 1/5

8) y = -x - 7

Step-by-step explanation:

5x + 3y = 0

3y = 0 - 5x

y = 0/3 - 5/3x or…

y = - 5/3x
- - - - - - - - - - - - - - - - -
4x + 3y = 0

3y = 0 - 4x

y = 0/3 - 4/3x or…

y = - 4/3x

(4, -9) , (-13, -8)

m = slope

m = change in y/change in x

m = (y2 - y1)/(x2 - x1)

m = (-8 - -9)/(-13 - 4)

m = 1/-17 or…

m = - 1/17

(8, 12) , (5, -6)

m = slope

m = change in y/change in x

m = (y2 - y1)/(x2 - x1)

m = (-6 - 12)/(5 - 8)

m = -18/-3

m = 18/3 or…

m = 6

through (3, -2), parallel
to y = -3/5x

y = -3/5x + b

-2 = -3/5(3) + b

-2 = -9/5 + b

b = -2 - -9/5

b = - 1/5

The line would be y = -3/5x - 1/5
- - - - - - - - - - - - - - - - -
y = -x

(-5, -2)

-2 = 5 + b

b = -2 - 5

b = -7

The line would be y = -x - 7

If -2x+3=7 and 3x+1= 5+y
sertanlavr [38]

Answer: x = -2, y = -10

Step-by-step explanation:

solve for x first in the equation -2x+3=7

-2x+3=7

-2x = 4

x = -2

now plug that x value into the other equation so we can find y

3x+1 = 5+y

3(-2)+1 = 5+y

-6+1 = 5+y

-5=5+y

-10 = y

I already answered this but I just want to make sure if I did it right
galben [10]
\bf \left( \cfrac{2}{3} \right)^3\cdot \left( \cfrac{3}{5} \right)^3\implies \cfrac{2^3}{\underline{3^3}}\cdot \cfrac{\underline{3^3}}{5^3}\implies \cfrac{2^3}{5^3}\implies \cfrac{8}{125}

In letters (b) leave your answer in terms of the constants a, b, c and d
Ivan
I think you mean to find b in terms of the constants a, c and d.

(x + a ) / b - c = d

(x + a) / b  = c + d

Cross multily:-

x + a = b(c + d)

b =   (x + a) / (c + d)

In ΔNOP, n = 910 inches, o = 110 inches and p=820 inches. Find the measure of ∠P to the nearest degree.
Sophie [7]

Given:

In ΔNOP, n = 910 inches, o = 110 inches and p=820 inches.

To find:

The measure of ∠P to the nearest degree.

Solution:

According to the law of cosine:

\cos A=\dfrac{b^2+c^2-a^2}{2bc}

Using law of cosine in triangle NOP, we get

\cos P=\dfrac{n^2+o^2-p^2}{2no}

Putting the given values, we get

\cos P=\dfrac{(910)^2+(110)^2-(820)^2}{2(910)(110)}

\cos P=\dfrac{828100+12100-672400}{200200}

\cos P=\dfrac{167800}{200200}

\cos P=0.83816

Taking cos inverse on both sides, we get

P=\cos^{-1}(0.83816)

P=(33.05367)^\circ

P\approx 33^\circ

Therefore, the measure of ∠P is 33°.
