Answer:

Step-by-step explanation:

Answer: A=24

To figure this out multiply 8 and 6 to get 48.

A triangle is half of a square.

Divide 48 by 2 to get 24.

Find the equation of the line through point (3,−3) and parallel to y=3x−4. Use a forward slash (i.e. "/") for fractions (e.g. 1/

exis [7]

Answer:

y =3x - 12

Step-by-step explanation:

I'm fairly certain this is the answer.

Consider the point (3,-3). In terms of variables this is written (x,y).

Remember that the equation for slope is y = mx + b.

In that equation, "b" is your y-intercept, and "m" is your slope.

If 2 lines are parallel, they have the same slope but different y-intercepts. So you can use the slope from the equation y=3x-4 to find the parallel line. You can also plug in the values 3 and -3 to solve for b, our y-intercept.

If we set up the equation, we have -3 = 3(3) + b.

Now solve for b.

-3 = 9 + b

Combine like terms, so that -12 = b, and you have your y-intercept.

To create the equation, take out the coordinate pair that the line passes through, and only have the SLOPE and the Y-INTERCEPT showing in the equation.

Therefore, y = 3x - 12

F(x)=3x-6 find f(4) I

Akimi4 [234]

To find f(4), you want to substitute x for 4 in the equation. It would look like:

f(4) = 3(4) - 6

Then, just do the math:

f(4) = 12 - 6
f(4) = 6

Hope this helps! :)

Consider kite WXYZ.

kondaur [170]

Answer:

a = 8; b = 40

Step-by-step explanation:

<em>See attached</em>

<h3>Given </h3>

XY = 3a - 5
YZ = a + 11
∠W = 50°
∠X = 3b
∠Y = 70°

Values of a and b

<h3>Solution</h3>

<u>Since XY and YZ are congruent sides, XY = YZ</u>

3a - 5 = a + 11
3a - a = 11 + 5
2a = 16
a = 8

<u>The angles Z and X are equal and the sum of 4 angles is 360°, therefore:</u>

3b + 3b + 50° + 70° = 360°
6b + 120° = 360°
6b = 240°
b = 40°

<u>Correct option is the last one </u>

a = 8; b = 40°
