Answer 1

Answer:

[tex]y = 50x[/tex]

Step-by-step explanation:

Let's start off by trying to find the slope/gradient (commonly denoted as [tex]m[/tex]) of this function

[tex]m = \frac{\Delta y}{\Delta x}[/tex]

This means we divide the change in y over the change in x

Let's pick, for example, x = 3 (who's corresponding y is 150) and x = 4 (who's corresponding y is 200)

[tex]m = \frac{200 - 150}{4 - 3}\\\\m = 50[/tex]

Now we have this:

[tex]y = 50x+b[/tex]

Let's plug in a random value of x and y from this function in order to find b. I'll pick x = 2:

[tex]100 = 50\cdot 2 + b\\100 = 100 + b\\b = 0[/tex]

Since b is 0, we don't have to write it on our equation, meaning that our final equation is just

[tex]y = 50x[/tex]

To verify this, let's say we didn't know the value of y when x is equal to 4 and all we had was that equation:

[tex]y = 50\cdot 4\\y = 200[/tex]

Just like it is on the graph :)

Good luck!

Find the equation of the line.

Can I please get an explanation :)

Answers

Answer:

the equation is in form

y=mx+b where

m=slope

and

b=y-int (the y value for the vertex)

first we look to see what the y value is for the point where x=0 and we can see that it is 5 so b=5

then we look at the slope, slope it the amont of units up then to the side are needed to reach the next point, in this case the line goes up 1 then to the right 1 so the slope is 1/1 (1) so the full equation is

y=x+5

Answers

Answer:

$11.60

Step-by-step explanation:

$9.39

Tax: 3.5%

3.5 ÷ 100 = 0.035 × 9.39 = 0.33

Tax 0.33

9.39 + 0.33 = $9.72

Tip: 20%

20÷ 100 = 0.2 × 9.39 =1.88

tip 1.88

9.72 + 1.88 = 11.60

total $ 11.60

$11.60

Given the figure below, find the values of x and z.
(10x - 65)
(9x - 49)

Answers

(10x - 65) degrees is equal to (9x - 49) degrees, therefore you can set them into an equation.

(10x - 65) = (9x - 49)

By subtracting 9x in both sides,

(10x - 9x) - 65 = (9x -9x) - 49

x - 65 = -49

By adding 65 in both sides,


x - 65 + 65= -49 + 65
x = 16


Next, to find the value of z, it’s important to know that the straight line has 180 degrees. Then you would substitute the x value you found into one of your equation and subtract it from 180.

10 (16) - 65 = 160 - 65 = 95

Now you know that (10x - 65) degrees is equal to 95 degrees,

180 - 95 = z = 85


Answer: x = 16
z = 85

to both sides of the equation

6 − 1 0 = 4 + 4 0

6x-10=4x+40

6x−10=4x+40

6 − 1 0 + 1 0 = 4 + 4 0 + 1 0

6x-10+{\color{#c92786}{10}}=4x+40+{\color{#c92786}{10}}

6 = 4 + 5 0

6x=4x+50

6x=4x+50

Subtract

from both sides of the equation

6 = 4 + 5 0

6x=4x+50

6x=4x+50

6 − 4 = 4 + 5 0 − 4

6x{\color{#c92786}{-4x}}=4x+50{\color{#c92786}{-4x}}

6x−4x=4x+50−4x

A right square pyramid is shown. The height of the pyramid is 6 units. The distance from the center of the base of the pyramid to vertex D is 2.5 units, as shown. Find the length of segment AD, in units.

Answers

Answer:

Length of side AD is 6.5 units.

Step-by-step explanation:

Let the center of the rectangular base of the given pyramid is O,

From the picture attached,

m∠AOD = 90°

By applying Pythagoras theorem in the right triangle AOD,

AD² = AO² + OD²

AD² = 6² + (2.5)²

AD = √42.25

AD = 6.5 units

Therefore, length of side AD is 6.5 units.

Sean and his chartered a fishing boat for the day Sean caught a blue marlin and an amberjack. The weight of the blue marlin way 12 times as great of the amberjack. The combined weight of both fish was 273 pounds. How much did each fish weight

Answers

Answer:

The weight of the blue marlin = b = 252 pounds

The weight of the amber jack = a = 12 pounds

Step-by-step explanation:

Sean and his chartered a fishing boat for the day Sean caught a blue marlin and an amberjack.

Let

The weight of the blue marlin = b

The weight of the amber jack = a

The weight of the blue marlin weigh 12 times as that of the amberjack.

b= 12a

The combined weight of both fish was 273 pounds.

= a + b = 273 pounds

b = 12a

Hence

a + 12a = 273 pounds

13a = 273 pounds

a = 273 pounds/13

a = 21 pounds

b = 12a

b = 12 × 21 pounds

= 252 pounds

Hence:

The weight of the blue marlin = b = 252 pounds

The weight of the amber jack = a = 12 pounds

Solve for x. 5x - 29> -34 OR 2x +31 < 29 ​

Answers

Answer:

Step-by-step explanation:

In this question, you would solve the inequalities.

Solve:

Inequality 1:

5x - 29> -34

Add 29 to both sides

5x > -5

Divide both sides by 5

x > -1

Inequality 2:

2x +31 < 29

Subtract 31 from both sides

2x < -2

Divide both sides by 2

x < -1

Your answer would be: x > -1 or x < -1

Answers

Answer:

g-1(x)=SQRT{(x-4)/2} + 4

Step-by-step explanation:

I assume that the 2 is the exponent so ^ represents exponent

We know your function is g(x)=2(x-3)^2+4

For inverse functions we swap x and y values, note g(x) is like the y value

Isolate for y

y=2(x-3)^2+4

x=2(y-3)^2+4

(x-4)/2 = (y-3)^2

SQRT{(x-4)/2} + 4 = y

Therefore g-1(x)=SQRT{(x-4)/2} + 4
