Answer:

2t - 7

Step-by-step explanation:

We have the expression 2(t - 4) + 1 and are asked to see which is the equivalent.

To solve, we need to first get rid of the parenthesis, which is done by distributing the number outside of the parenthesis to the numbers inside of the parenthesis :

2(t - 4) + 1

(2 * t) - (2 * 4) + 1

2t - 8 + 1

Combine like terms :

2t - 7

Choose 3 values that would make thi inequalitie true 28+x>42

Y_Kistochka [10]

9514 1404 393

Answer:

14.01, 493, 87

Step-by-step explanation:

Subtracting 28 from both sides tells you the range of values you need to be looking at.

28 + x > 42

x > 14

Any values more than 14 will make the inequality true. Three of them are ...

14.01, 493, 87

4. Represent the ordered pairs in the mapping diagram as a set of ordered pairs and as a table.

Firlakuza [10]

Answer/Step-by-step explanation:

✔️As a set of order pairs, the mapping can be represented as (x, y), where x = input and y = output.

Thus:

{(1, 6), (2, 6), (3, 6), (4, 8)}

✔️As a table we have input as x, and y as output, such as:

x | y

1 | 6

2 | 6

3 | 6

4 | 8

Work out m and c for the line: 3 y + 6 x = − 3

Usimov [2.4K]

Answer:

m is -2 and c is -1

Step-by-step explanation:

• Let's first phrase out the general equation of a line

${ \rm{y = mx + c}}$

m is the slope
c is the y-intercept

[ remember that a general line equation must be in slope - intercept form as shown above ]

• from our question, we are given the equation;

${ \rm{3y + 6x = - 3}}$

• let's make y the subject in order to make the equation in slope - intercept format.

→ remember to apply "subject making knowledge"

${ \rm{3y = - 3 - 6x}} \\ \\ { \rm{3y = - 6x - 3}} \\ \\ { \rm{ \frac{3y}{3} = \frac{ - 6x}{3} - \frac{3}{3} }} \\ \\ { \boxed{ \rm{y = - 2x - 1}}}$

• The above boxed equation is now a general equation. Let's extract out slope, m and y-intercept, c

${ \rm{m \: \dashrightarrow \: - 2}} \\ \\ { \rm{c \: \dashrightarrow \: - 1}}$
