Answer:b

Omnivore and predator

Step-by-step explanation:

D

Step-by-step explanation:

the y is -2

and the slope is 2/5

which means it is y=2/5x -2

Answer:

Cheetahs can go from 0 to 60 miles per hour in just 3.4 seconds and reach a top speed of 70 miles per hour. While they are the fastest land animal in the world, they can only maintain their speed for only 20 to 30 seconds.

Answer:

ok this was a good one so here

Step-by-step explanation:

4 120 30

25 750 30

9 270 30

Explanation:

Each time x goes up by 1, y goes up by 18

slope = rise/run

slope = (change in y)/(change in x)

slope = 18/1

slope = 18

You can also use the slope formula to get the same answer. Let's say we picked the points (2,36) and (3,54). We then would get

m = (y2-y1)/(x2-x1)

m = (54-36)/(3-2)

m = 18/1

m = 18

We get the same result as before.

Since x represents the number of years and y is the number of inches, the slope of 18/1 indicates an increase of 18 inches per 1 year, or just 18 inches per year.

Step-by-step explanation:

The word "product" means that the operation is multiplication. So the two numbers need to be multiplied. In algebra, the way you multiply a constant and a variable is simply by putting the two next to each other with no other symbol.

Answer:

they are both divisible by 3

Step-by-step explanation:

Answer:

The required value of x is 12 units.

Step-by-step explanation:  Given that the figure A is a scale image of figure B.

We are to find the value of x.

Since figure A is the scale image of figure B, so both the figures are similar to each other.

Also, the corresponding sides of the similar figures are proportional, so we get

Thus, the required value of x is 12 units.

Answer:

x=2y−47x

Step 1: Add 47x to both sides.

x+47x=−47x+2y+47x

48x=2y

Step 2: Divide both sides by 48.

Answer:

A

Step-by-step explanation:

To find an inverse function you switch f(x) and x, and solve for f(x) (in this case you also rename it to g(x) )

inverse of y=(x-4)/5  is  

5x =  x -4

x = 5x + 4  so A works

Answer:

[tex]y = 7(3^x)[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1) = (0,7)[/tex]

[tex](x_2,y_2) = (4,567)[/tex]

Required

Determine the formula

An exponential function is of the form:

[tex]y = ab^x[/tex]

For point [tex](x_1,y_1) = (0,7)[/tex]

[tex]7 = ab^0[/tex]

[tex]7 = a*1[/tex]

[tex]7 = a[/tex]

[tex]a = 7[/tex]

For point [tex](x_2,y_2) = (4,567)[/tex]

[tex]567 = ab^4[/tex]

Substitute 7 for a

[tex]567 = 7*b^4[/tex]

Divide both sides by 7

[tex]81 = b^4[/tex]

Take 4th root of both sides

[tex]\sqrt[4]{81} =\sqrt[4]{b^4}[/tex]

[tex]\sqrt[4]{81} =b[/tex]

[tex]b = \sqrt[4]{81}[/tex]

[tex]b = 3[/tex]

Substitute 7 for a and 3 for b in [tex]y = ab^x[/tex]

[tex]y = 7 * 3^x[/tex]

[tex]y = 7(3^x)[/tex]

Answer:

12

Step-by-step explanation:

The sum of two interior angles in a triangle is equal to an exterior angle

3x + 4 + 2x + 1 = 6x - 7 add like terms

5x + 5 = 6x - 7

5 + 7 = 6x - 5x

12 = x

Answer:

0.5676

Step-by-step explanation:

We have been given these informations from this question ,

probability of 4% = 0.04

q = 1 - p = 1 - 0.04 = 0.96

Sample size n = 60

We solve further by Using binomial probability formula,

P(X = x) = (nCx)*px*(1 - p)^n - x

We have:

(60C0)x 0.04⁰x(0.96⁶⁰+(60C1)x0.04¹x(0.96)⁵⁹+(60C2)x0.04²x (0.96)⁵⁸

From this we would get the probability to be = 0.5676

Answer:

1. $82,500

2. 169 : 110

Step-by-step explanation:

The computation is shown below:

Given that

1. Ratio between two computers is 3:2

And the first computer cost is $55,000

Let us assume the price of the second computer be x.

As we know that

Product of extremes = Product of mean.

2 : 3 :: 55000 : x .

Now cross mutiplication is to be done

2x = $55,000 × 3

x = $1,650,000 ÷ 2

= $82,500

2. Now if the price of the 2nd computer rised by $2,000

So the new cost would be

= $82,500 + $2,000

= $84,500

Now the ratio would be

= $55,000 :  $84,500

= 169: 110
