1. is C because it says sum, which means add.
2. is B because we had to add 6+3 to make it equal
3. We can input 6 into h and get 19, when used with the rule of PEMDAS.
4. For perimeter we just have to add all sides, the answer is 128.
5. We have to multiply that by 4 to get the perimeter. Answer is 76.

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

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

All angles in a triangle add up to 180

So we can make an equation: 180=112+25+x+17

Add like terms

180=154+x

Move 154 to the other side as a negative number

X is equal to 26
