-32

-8

-2

Step-by-step explanation:

$y = 6x - 2$

$y_1 = 6(-5) - 2 = -30 -2 = -32$

$y_2 = 6(-1) - 2 = -6 -2 =-8$

$y_3 = 6(0) - 2 = 0 -2 = -2$

$y_4 = 6(1) - 2 = 6 -2 = 4$

Step-by-step explanation:

Ok so the function rule is: y=6x-2

We have 4 sets of numbers under the value "x." That means we have to input the given values into the function.

First is x=-5. We input -5 into the function so we get y=6(-5)-2. We multiply 6 and -5 and we get -30, then we subtract 2 from -30. Then for the answer for the first column, we get -32 for the y value.

Now we have x=-1. We input the number for x in the function and we get y=6(-1)-2. We multiply 6 and -1 and we get -6, then we subtract -2 from -6 and we get -8. So out y value for the second row is -8.

Try the next two on your own to see if you understand. If you still don't understand please comment under this answer. I'll try to respond as quickly as I can.

Answer: <em><u>5 11/12</u></em>

Step-by-step explanation:

Since they only walked on Monday, Wednesday and Thursday,

You have to add 3/4 + 1 2/3 + 3 1/2

So, 3/4 + 1 2/3 + 3 1/2 =

3/4 + 2/3 + 1/2 = 1 11/12

1 + 3 = 4

4 + 1 11/12 = 5 11/12

1. Given points ????(3, −5) and ????(19, −1), find the coordinates of point ???? that sit 3/8 of the way along AB ,close to A th

Nastasia [14]

Answer: The required co-ordinates of point C are (9, -3.5).

Step-by-step explanation: We are given the points A(3, -5) and B(19, -1).

We are to find the co-ordinates of point C that sit 3/8 of the way along AB, where the point P is close to A than to B.

According to the given information, we have

$\dfrac{AC}{AB}=\dfrac{3}{8}\\\\\Rightarrow \dfrac{AC}{AC+BC}=\dfrac{3}{8}\\\\\Rightarrow 8AC=3AC+3BC\\\\\Rightarrow 5AC=3BC\\\\\Rightarrow AC:BC=3:5.$

So, point C divides the line segment AB in the ratio 3 : 5.

We know that

if a point Q divides a line segment joining the points S(a,b) and T(c,d), in the ratio m : n, then the co-ordinates of Q are

$\left(\dfrac{mc+na}{m+n},\dfrac{md+nb}{m+n}\right).$

Therefore, the co-ordinates of point C are

$\left(\dfrac{3\times19+5\times3}{3+5},\dfrac{3\times(-1)+5\times(-5)}{3+5}\right)\\\\\\=\left(\dfrac{57+15}{8},\dfrac{-3-25}{8}\right)\\\\=(9,-3.5).$

Thus, the required co-ordinates of point C are (9, -3.5).

NEED ANSWER ASAP- MARK AS BRANLIEST

Answer:

x = 1 +√5

Step-by-step explanation:

There are different formulas for the area of a triangle available, depending on the given information.

<h3>Formulas</h3>

When two sides and the angle between them are given, the relevant area formula is ...

Area = 1/2(ab)sin(C)

When the base and height of a triangle are given, the relevant area formula is ...

Area = 1/2bh

<h3>Equal Areas</h3>

The problem statement tells us the two triangles shown have equal areas. That means the two formulas will give the same result.

Area from angle = Area from base/height

1/2(x·x)sin(30°) = 1/2(x-2)(x+1)

x² = 2(x² -x -2) . . . . . . . . . . . use sin(30°) = 1/2, multiply by 4

x² -2x -4 = 0 . . . . . . . . subtract x², eliminate parentheses

(x -1)² = 5 . . . . . . . . . add 4+1 to complete the square

<h3>Value of x</h3>

x = 1 ± √5 . . . . . . take the square root, add 1

The value of x must be greater than 2 in order for the triangle side lengths to be positive. (x-2 > 0) This means x = 1-√5 is an extraneous solution.

The value of x is 1 +√5.
