Answer:

A. 79.4
B. 84
C. Science class

Step-by-step explanation:

Average test score in math class

f(x) = 0.2x + 79

Average test score in science class

As per table the rate of change is -2, therefore g(x) is

g(x) = -2x + 88, because
g(1) = -2 + 88 = 86

Part A: Determine the test average for your math class after completing test 2.

f(2) = 0.2*2 + 79 = 0.4 + 79 = 79.4

Part B: Determine the test average for your science class after completing test 2

g(2) = 84 given in the table

Part C: Which class had a higher average after completing test 4?

f(4) = 0.2*4 + 79 = 0.8+ 79 = 79.8
g(4) = -2*4 + 88 = - 8 + 88 = 80

Science class had higher class

Select the correct product. (y + z)3

Gre4nikov [31]

Answer:

3y + 3z

Step-by-step explanation:

(y + z)3

As the parenthesis contains 2 different variables, we cannot add them

Distribute (Multiply 3 by y and z)

3y + 3z

This is the simplest that this expression can get

Find the distance between the points (0,-2) and (6,-6)

goldenfox [79]

Answer:

Formular:

$length = \sqrt{ {(x_{1} - x_{2} )}^{2} + {(y_{1} - y_{2} ) }^{2} }$

x1 » 0

x2 » 6

y1 » -2

y2 » -6

$l = \sqrt{ {(0 - 6)}^{2} + {( - 2 - 6)}^{2} } \\ \\ l = \sqrt{ {( - 6)}^{2} + {( - 8)}^{2} } \\ \\ l = \sqrt{36 + 64} \\ \\ l = \sqrt{100}$

for the √100 in surds:

$l = \sqrt{10 \times 10} = \sqrt{ {10}^{2} } = ( {10}^{2} ) {}^{ \frac{1}{2} } \\ \\ { \boxed{ \boxed{distance = 10 \: \: units}}}$

Which equation represents a proportional relationship between the x and y values a) y+4=3x b) y-3x=0 c) y+5x=6 d) y+1/4x=2

stich3 [128]

Answer: B

Option is B) y-3x=0 represents a proportional relationship between the x and y values

Explanation:

Case 1 = y+4=3x

From the above equation we can see that if we change the value of x, the value of y does not changes by proportionality due to the presence of 4 .

Case 2: y-3x=0

From the above equation we can see that if we change the value of x, the value of y changes by proportionality.

Hence the correct option is B.

Case 3 = y+5x=6

From the above equation we can see that if we change the value of x, the value of y does not changes by proportionality due to the presence of 6.

Case 4 = y+1/4×x=2

From the above equation we can see that if we change the value of x, the value of y does not changes by proportionality due to the presence of 2.
