Answer:

[tex]h = \frac{7}{2} [/tex]

Step-by-step explanation:

1) Divide both sides by -4.

[tex]h = \frac{ - 14}{ - 4} [/tex]

2) Two negative makes a positive.

[tex]h = \frac{14}{4} [/tex]

3) Simplify 14/4 to 7/2.

[tex]h = \frac{7}{2} [/tex]

Therefor, the answer is 7/2.

Answer:

They are 24, 692 feet aprart

Step-by-step explanation:

Let us assume at the instance we are measuring their position, that Pluto is at the highest point in the air, which is = 24,568 feet, and Goofy is at the lowest point of the sea (that he can go) = 124 feet.

Before we can proceed with the addition, we need to establish a datum, which will serve as the reference point from which the two distances are measured. This definitely is the sea level, because altitude and depth are usually measured above and below sea level.

Pluto's location to the sea level = 24,568 feet

Goofy's Location to the sea level = 124 feet

their distance apart = 24,568 feet + 124 feet =24, 692 feet apart

Answer:

Step-by-step explanation:

From the dot plot of start of school year,

Maximum value of the miles run = 10

Minimum value of the miles run = 5

Range of the data set = 10 - 5

                                    = 5 miles

From the dot plot of End of school year,

Maximum value of the miles run = 10

Minimum value of the miles run = 6

Range of the data set = 10 - 6

                                    = 4 miles

The range at the start of the year was 5 miles and the range at the end of the year was 4 miles.

Answer:

True

Step-by-step explanation:

2(x+3) = 5x+6-3x

2x+6=5x-3x+6

2x+6=2x+6

Answer

True

Step-by-step explanation:

Cause 2×X=2x and 2×3=6

so total = 2× + 6 =5× + 6 - 3x

or, 2x + 6 = 5x - 3x + 6

or, 2x + 6 = 2x + 6

Answer:

60

Step-by-step explanation:

To find the range you subtract the highest and lowest value

The highest value on this graph is 105 from the month of May and the lowest value is 45 from the month of March.

When you do 105-45 you get 60 which is the range

Answer:

What are you trying to solve?

Step-by-step explanation:

Answer:

16. length=4

18. length=7

Step-by-step explanation:

Formula = area=length x height

16. 44=11xL

44 divided by 11 equals 4

18. 49=7xL

49 divided by 7 equals 7

Answer:

30 cm

Step-by-step explanation:

add all sides and use 7 for the bottom line because 5+2=7 and use 8 for the side because 5+3=8.

Answer:

X=.8

Step-by-step explanation:

6 x -2 = -12

-12 = 3, -4

y = 6x^2 + 3x - 4x - 2

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

(2x + 1) (3x - 2) = 0

2x = -1, 3x = 2

x = -1/2, 2/3

pls give brainliest im trying to level up :))

Answer:

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

Step-by-step explanation:

Given :-

We need to factor out the given expression. For that we may use the middle term splitting method. Taking the equation,

[tex]:\implies[/tex] y = 6x² - x - 2

[tex]:\implies[/tex] y = 6x² - 4x + 3x-2

[tex]:\implies[/tex] y = 2x ( 3x -2) +1( 3x -2)

[tex]:\implies[/tex] y = (2x + 1)(3x -2 )

Step-by-step explanation:

Answer:

B. ​No, because while there is no linear​ correlation, there may be a relationship that is not linear.

Step-by-step explanation:

Relationships between variables are diverse and fitted model of a dataset for each of the models will usually differ. That is the lebl of association between variables for a linear model may differ and better than a quadratic model or an exponential may perform. For r = 0 ; this means no relationship exists between the variables, however , this is the information for the linear model, which clearly depicts that no assicitio exist for the linear fit. A model change could result in a differ and slightly or highly correlated R value.

Answer:

(24,4,84)

Step-by-step explanation:

Since they restricted our domains to certain x values, we can find the range by plugging in the x values to find it y value or output.

[tex]f( - 2) = 5( { - 2}^{2} ) + 4[/tex]

[tex]5(4) + 4 = 24[/tex]

[tex]f(0) = - 5( {0}^{2} ) + 4 = 4[/tex]

[tex]5(4) {}^{2} + 4 = 84[/tex]

So our range is (24,4,84)

Answer:

f(x)=5x²+4

f(-2)=5×(-2)²+4

f(0)=5(0)²+4

f(4)=5×(4)²+4

so the range of function{-2,0,4}is{24,4,85}
