Answer:On a Road trip, a family drives 350 miles per day. How many days, d, must they travel to reach a distance of at least 1,400 miles?

Step-by-step explanation:

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:

19 is the numerical value

Step-by-step explanation:

Also, when it's converted to number I.e.

E = 14 , B = 11

= 14 + 11 = 25

But in letters the numerical value is

E + B = 19

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:

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:

12b+1

Step-by-step explanation:

-4 + 4b + 5 + 8b

12b+1

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:

x = 1

Step-by-step explanation:

4x + 1 - x = -2(x - 3)

3x + 1 = -2x + 6

3x + 2x = 6 - 1

5x = 5

x = 1

Answer:

  1) ΔCBA ~ ΔCQR

  2) ΔCDE ~ ΔCTS

Step-by-step explanation:

In both cases, the vertical angles at C are congruent. The marking shows an additional internal angle is congruent, so the triangles are similar by the AA similarity postulate.

The vertex at C is named first, followed by the marked angle in each of the given similarity statements. The same order must be used for the vertices in the similar triangle.

  1) ΔCBA ~ ΔCQR

  2) ΔCDE ~ ΔCTS

Answer:

A) (6 , 8)

B) (-6 , 2 )

C) (4 , -4)

Answer:

1. y = -11/4; (-2, -11/4)

2. y = -1; (0, -1)

3. y = -1/8; (1, -1/8)

4. y = 0; (8/7, 0)

5. y = 3/4; (2, 3/4)

Step-by-step explanation:

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

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

therefore the slope is 1

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. :)

I don't know let me think about it

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:

(7, -4)

Step-by-step explanation:

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
