Answer 1

Answer:

First question: 2/3

Second question: -2

Step-by-step explanation:

2x - 3y = 6

Subtract 2x from both sides

-3y = -2x + 6

Multiply by -1

3y = 2x - 6

divide by 3

y = 2/3x -2

The equation basically asks for slope, so 2/3

x + 1/2y = 5

Subtract x

1/2y = -x + 5

multiply by 2

y = -2x + 10

it is -2

A line goes through the point (–4,–2) and has an x-intercept of –1.

Which point also lies on the line?
(–6,–5)
(3,2)
(4,5)
(5,4)

Answers

Answer:

(5,4)

Step-by-step explanation:

thanks to the second information we know that a certain second point of the line is (-1,0)

Now we can use a formula to find the equation of the line, that is

(y-y1)/(y2-y1) = (x-x1)/(x2-x1) where x and y 1 and 2 are the coordinates of the points.

(y+2)/2 = (x+4)/(-1+4)

y+2/2 = (x+4)/ 3

3y+6 = 2x+8

2x-3y+2 = 0

now we have to find the point that make true the equation (we have to sobstitute x and y with the coordinates of the given points)

1)  -12 +15 + 2 = 0 ; 3 = 0 (wrong)

2) 6-4+2 = 0 ; 4 = 0 (wrong)

3) 8-15+2 = 0 ; -5 = 0 (wrong)

4) 10-12+2 = 0 ; 0=0 (true)

so (5,4) is the correct answer

Answers

Answer:

D. 110

Step-by-step explanation:

30+40=70

180-70=110

Answer:

∠CEF = 110°

Step-by-step explanation:

ΔBED ,

∠BED +  ∠BDE + ∠DBE = 180 {Angle sum property}

∠BED + 40 + 30 = 180

∠BED + 70 = 180

∠BED = 180 -70

∠BED = 110°

∠CEF = ∠BED     {Vertically opposite angles}

∠CEF = 110°

Answer:

Step-by-step explanation:

Hello There!

The polygon shown below is a kite

We can calculate the area of a kite using this formula

[tex]A=\frac{pq}{2}[/tex]

where p and q = the diagonals

The diagonals of the shown kite are 12 ( found by adding 10 and 2) and 12 ( found by adding 6 and 6 )

So having found the diagonals we plug them into formula

[tex]A=\frac{12*12}{2} \\12*12=144\\\frac{144}{2} =72[/tex]

so we can conclude that the area of the polygon is 72

Each of these statements are part of True/False game. Which statement is correct?
The function is nonlinear.
The graph of the points of the function will form a line.
The function is proportional.
The difference between consecutive output values is a constant.
The function is exponential.

Answers

Answer:

E. (The function is exponetial)

Step-by-step explanation:

We look at the output values and subtract them from their previous value to see it's slope.

6-2 = 4

12-6 = 6

4 ≠ 6, meaning that the slope is not constant.

4 < 6, meaning that the slope is increasing, meaning the function is exponential.
