Answer:

y=-1/4x-6

Step-by-step explanation:

y intercept is -6 and slope is -1/4

point slope is y-y1=m(x-x1)

you can use and point. i am using (0,-6)

y--6=-1/4(x-0)

y+6=-1/4x

-6 -6

y=-1/4x-6

X = 10 - y and y = x - 8
garik1379 [7]

Answer:

x = 9 and y = 1

Step-by-step explanation:

Here,

x = 10 - y and y = x - 8 is given

then, name the equation

x = 10 - y ...(1)

y = x - 8 ...(2)

Now, put the value of x in equation (2) we get

y = x - 8

y = (10 - y) - 8

y = 10 - y - 8

y + y = 10 - 8

2y = 2

y = 2÷2

y = 1

Here, we get the value of y = 1

Now, we put the value of y in equation (1) we get

x = 10 - y

x = 10 - (1)

x = 10 - 1

x = 9

<h3><em><u>VERIFICATION</u></em><em><u>:</u></em></h3>

x = 10 - y

9 = 10 - 1

9 = 9

Hence, LHS = RHS

Slope of (-2,6) (-5,-4)
alekssr [168]

Answer:

10/3

Step-by-step explanation:

(-2, 6) & (-5, -4)

To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values:

(-4 - 6) / (-5 - (-2))

Simplify the parentheses.

= (-4 - 6) / (-5 + 2)

= - 10 / -3

Simplify the fraction.

-10/-3

= 10/3

This is your slope.

Hope this helps!

i haven't submitted a single assignment for this class since winter break bc i didn't realize she was assigning things on goform
rosijanka [135]

Answer and Step-by-step explanation:

<u>Trigonometric Function (These only work for right triangles):</u>

SOH-CAH-TOA

S = Sine = sin

C = Cosine = cos

T = Tangent = tan

O = Opposite (side)

H = Hypotenuse (side)

A = Adjacent (side)

SOH = sin(angle) = \frac{opposite}{hypotenuse}

CAH = cos(angle) = \frac{adjacent}{hypotenuse}

TOA = tan(angle) = \frac{opposite}{adjacent}

1. sinQ (Q is the angle) = \frac{14}{50}  = \frac{7}{25} = 0.28

Use Pythagorean Theorem to find side PQ.  14^{2} + PQ^{2}= 50^{2} \\PQ^{2}  = 2304\\PQ = 48

2. cosQ = \frac{48}{50} = \frac{24}{25} = 0.96

3. tanQ = \frac{14}{48}  = \frac{7}{24}  = 0.29
