Answer:

-2

Step-by-step explanation:

You take [tex]\frac{2}{7}[/tex] of [tex]400[/tex].

Which is: [tex]\frac{800}{7} = 114.8 mL[/tex]

The linear function will be represented as h(x) = -3x - 10.5. The correct option is A.

The terms "linear function" in mathematics refer to two different but related ideas: A linear function is a function with a graph that is a straight line in calculus and related fields.

The given data in the table is:-

X   -7.5     -3.5      -1         2

Y    12         0       -7.5    -16.5

The linear function can be written as:-

y = mx + c

m = ( 0 - 12 ) / ( -3.5 + 7.5 )

m = -12 / 4

m = -3

The y-intercept will be:-

y = mx + c

0 = ( -3 x -3.5 ) +c

c = -10.5

The linear function is:-

h(x) = -3x - 10.5

Answer:

C) y is equal to 10.5x

Step-by-step explanation:

$31.50 is charged for 3  hours so, for 1 hour we need to divide 31.50 by 3, which results in 10.50. So 1 hour of babysitting is $10.50

this is because x is equal to the number of hours they babysit. we do not know the actual so it is replaced with x

and y is equal to the sum of 10.5x because we multiply the number of hours worked, and the amount per hour.

x-1/2=0

Given:

The data values are 22, 23, 23, 24, 24, 24, 25, 25, 25, 25, 26, 26, 26, 26, 26, 27, 27, 27, 28, 28, 28, 28, 29, 29, 30.

To find:

The five-number summary.

Solution:

We have,

22, 23, 23, 24, 24, 24, 25, 25, 25, 25, 26, 26, 26, 26, 26, 27, 27, 27, 28, 28, 28, 28, 29, 29, 30

Divide the data values on 2 equal parts.

(22, 23, 23, 24, 24, 24, 25, 25, 25, 25, 26, 26), 26, (26, 26, 27, 27, 27, 28, 28, 28, 28, 29, 29, 30)

Divide each parentheses in two equal parts.

(22, 23, 23, 24, 24, 24), (25, 25, 25, 25, 26, 26), 26, (26, 26, 27, 27, 27, 28), (28, 28, 28, 29, 29, 30)

Now,

Minimum value = 22

[tex]Q_1=\dfrac{24+25}{2}=24.5[/tex]

Median = 26

[tex]Q_2=\dfrac{28+28}{2}=28[/tex]

Maximum value = 30

So, the five number summary is 22, 24.5, 26, 28, 30.

Therefore, the correct option is D.

Answer: c=-1,b=5,a=-5

Step-by-step explanation: If c=-1, substitute it into the second equation first. The second equation becomes -2b-1=-11, simplify it becomes -2b=-10, divide by 2 it becomes -b=-5, so b=5. Then you substitute b and c into the first equation. The first equation becomes a+5+-(-4)=4, simplify it becomes a+5+4=4, Simplify again it becomes a=-5.

Answer:

x=32

Step-by-step explanation:

8(5/8x+4 = 3/8x+12)

5x+32=3x+96

2x+32=96

2x=64

x=32

Answer:

x = 32

Step-by-step explanation:

5/8x + 4 = 3/8x + 12

subtract 3/8 from both sides

2/8x + 4 = 12

simplify

1/4x + 4 = 12

subtract 4 from both sides

1/4x = 8

multiply each side by the reciprocal of 1/4

4/1 • 1/4x = 8 • 4/1

solve

x = 32

Answer:

Well the equation of the line is -3x+4, so we know the slope is -3/1
