Answer: The slope is -4/5

Step-by-step explanation: Try finding 2 points on the graph that are on the line, then use the following formula, rise / run. The slope is -4/5.

Answer:

start at (0,2) go up one over 3 to the right, and down 1 over 3 to the left

Answer:

slope is 1/3

the y intercept is (0,2)

Answer: -0.83

Step-by-step explanation:

A correlation coefficient(r) is used to determine the strength and direction of the relationship between two variables.

-1 ≤ r ≤1

For downward trend r is negative.

For strong correlation r should be closer to 1 or -1.

From the given correlation coefficients  -0.83 is both negative and closer to -1.

Hence, a correlation coefficient represents the strongest downward trend in a data set = -0.83

Answer:I think its 2

Step-by-step explanation:Im not really sure but i think thats the answer

Answer:

2

Step-by-step explanation:

Answer:

28 x 75 = 2,100 then you would divid 2,100 / 5 = 420 so thats your answer.

Answer:

[tex]y = 2(2) {}^{x} [/tex]

Step-by-step explanation:

It ask us to create a exponential function. A exponential function is represented by a equation like this

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

where a is the vertical stretch, b is the constant rate of growth, and x is the nth exponet.

Using the point 0,2

we can plug that in to find a part of the equation above.

let x=0 and y=2

[tex]2 = ab {}^{0} [/tex]

[tex]b {}^{0} = 1[/tex]

[tex]2 = a \times 1[/tex]

[tex]a = 2[/tex]

Let update the equation now since a equal 2

[tex]y = 2b {}^{x} [/tex]

Now let use point 2,8 to find the b value

let x=2 and y=8

[tex]8 = 2b {}^{2} [/tex]

Divide both sides by 2

[tex]4 = {b}^{2} [/tex]

take the sqr root of 4

[tex]b = 2[/tex]

Let update the equation

[tex]y = 2(2) {}^{x} [/tex]

Answer:

10x + 6y

Step-by-step explanation:

Let t = length of the third side

3x + 4y + 5x - y + t = 18x + 9y

8x + 3y + t = 18x + 9y

t = 10x + 6y

Answer:

64

Step-by-step explanation:

4^3 means to multiply 4 by itself three times, 4×4×4=64

Answer:

1

Step-by-step explanation:

[tex]\frac{rise}{run}=slope[/tex]

[tex]\frac{1}{1} =1[/tex]

therefore the slope is 1

plz mark me brainliest. :)

Answer:

y = x + 5

1 would be the slope AKA m

Step-by-step explanation:

y = mx + b

mx is change of y to the change in x.

m is the slope

As you can see in the problem above, everytime y moves up 1, x moves to the right 1.

b is the y intercept - where is y when x is at 0?

This will help you find the slope of future problems hopefully. :)

Answer:

B) [tex]10\sqrt{3}[/tex]

Step-by-step explanation:

So basically it's divided into 3 similar triangles and using ratios we can try to find x

long side/short side = long side/short side

(20)/(x) = (x)/(15)

[tex]x^{2}[/tex] = 300

x =  [tex]10\sqrt{3}[/tex]

I really hope I didn't make that too complicated-

Answer:

35*36=1260

Step-by-step explanation:

Answer:

35, 36

Step-by-step explanation:

Let the two consecutive positive integers be x and (x + 1)

According to the given information:

[tex]x(x + 1) = 1260 \\ \\ {x}^{2} + x - 1260 = 0 \\ \\ {x}^{2} + 36x - 35x - 1260 = 0 \\ \\ x(x + 36) - 35(x + 36) = 0 \\ \\ (x + 36)(x - 35) = 0 \\ \\ x + 36 = 0, \: \: x - 35 = 0 \\ \\ x = - 36, \: \: x = 35 \\ \\ \because \: x \in \: positive \: integer \\ \\ \therefore \: x \neq \: - 36 \\ \\ \therefore \: x = 35 \\ \\ x + 1 = 36[/tex]

Answer:

6(r - 5)

Step-by-step explanation:

GCF here is 6. So divide each term by 6.

6r - 30 = 6(r - 5)

Step-by-step explanation:

the answer to your question is 1 and 4

Answer:

Step-by-step explanation:

1 and 4 wrong

Answer:

Step-by-step explanation:

Pythagorean theorem,

Base² + altitude² = hypotenuse²

x² + 3² = 6²

x² + 9 = 36

      x² = 36 - 9

     x² = 27

x = √27

Answer:

D) x=sq rt 27

Step-by-step explanation:

using the Pythagorean theorem

6^2=3^2+x^2

36=9+x^2

27=x^2

x=sq rt 27

Answer:

Step-by-step explanation:

Answer:

x = 4

Step-by-step explanation:

ΔABC ≈ ΔDBE

set up a proportion of corresponding sides:

BD / BE = BA / BC

BA = 10 - x + x = 10

10-x / 3 = 10 / 5

cross-multiply:

5(10 - x) = 3(10)

50 - 5x = 30

-5x = -20

x = 4

Answer:

Rounding this off to the nearest hundred, we get that x is 12 units long.

Answer:

43ft

Step-by-step explanation:

side a = x ft

side b = 10 ft

side c = 18 ft

x = 14.967

rounds to = 15

10 + 18 + 15 = 43

43 ft of fence needed
