Answer:

When we have a black dot in some value, means that the value is included in the set of solutions (associated with the signs ≤ ≥, and with solid lines)

When we have a white dot, means that the value is outside the set of solutions (associated with the signs < > and with dashed lines).

In this case, we can see the solid line across the solid point, but the dashed line does not cross over the white dot, this implies that the white dot belongs to the set of solutions (because is inside the shaded area) so this is an incongruence.

The dashed line should pass over the white dot.

Factor the expression using the GCF. A. 2(4a + 8c) B. 4(2a + 4c) C. 8(a + 2c) D. 16( 12 a + c) Not multiple choice

dimulka [17.4K]

Note: The expression is missing. Consider the expression is $8a+16c$ .

Given:

The expression is

$8a+16c$

To find:

Factor form of the given expression by using GCF.

Solution:

We have,

$8a+16c$

Factors of each term:

$8a=2\times 2\times 2\times a$

$16c=2\times 2\times 2\times 2\times c$

The common factors are 2, 2 and 2. So,

$GCF(8a+16c)=2\times 2\times 2$

$GCF(8a+16c)=8$

Taking out the greater common factor (GCF) in the given expression, we get

$8a+16c=8(a+2c)$

Therefore, the required expression is $8(a+2c)$ and the correct option is C.

19. Suppose Misty purchased the 10-Day Ticket Package that

Luda [366]

Answer:

Part a) The table in the attached figure (see the explanation)

Part b) see the explanation

Step-by-step explanation:

Let

y ----> the total cost of Lift Tickets

x ----> the number of days

we know that

The linear equation in slope intercept form is given by

$y=mx+b$

where

m is the slope or unit rate of the linear equation

b is the initial value or y-intercept pf the linear equation

In this problem we have

The slope is equal to

$m=\$20\ per\ day$

The y-intercept is equal to

$b=\$80$

substitute

$y=20x+80$

<u><em>Complete the table</em></u>

Find the value of y for each value of x

For x=0 day

$y=20(0)+80=\$80$

For x=1 day

$y=20(1)+80=\$100$

For x=2 days

$y=20(2)+80=\$120$

For x=3 days

$y=20(3)+80=\$140$

For x=4 days

$y=20(4)+80=\$160$

For x=5 days

$y=20(5)+80=\$180$

For x=6 days

$y=20(6)+80=\$200$

Part b) Explain how you know the data in the table above is linear

The data in the table is linear, because satisfy the equation of the linear equation

$y=20x+80$

where

x is the variable independent or input value (the number of days)

y is the variable dependent or output value (the total cost of Lift Tickets)
