Rearrange the like terms first.
1. 4x+3x+9=30

add the like terms
2. 7x+9=30

move the 9 to the other side.
3. 7x=30-9

subtract them
4. 7x=21

divide bothers sides by 7
5.
\frac{7x = 21}{7}

which it will end with the result of
x=3

Determine the equation of a line that passes through A(2,5) and is parallel to the line defined by 3x−y+12=0. State the equation
Ksju [112]

Answer:

y = 3x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3x - y + 12 = 0 ( subtract 3x + 12 from both sides )

- y = - 3x - 12 ( multiply through by - 1 )

y = 3x + 12 ← in slope- intercept form

with slope m = 3

Parallel lines have equal slopes , thus

y = 3x + c ← is the partial equation

To find c substitute (2, 5) into the partial equation

5 = 6 + c ⇒ c = 5 - 6 = - 1

y = 3x - 1 ← equation of parallel line

Use the numbers 1,2,3,4,5,6,7,8,9 once each and in their natural order to obtain an answer of 100. You may use only the operatio
mixer [17]

Answer:

((1 × 2) + 3) × 4 × 5 + 6 - 7 - 8 + 9 = 100

Step-by-step explanation:

((1 × 2) + 3) × 4 × 5 + 6 - 7 - 8 + 9 = 100

= (2+3) x 4 x 5 + 6 - 7 - 8 + 9

= 5 x 4 x 5 + 6 - 7 - 8 + 9

= 100 + 6 - 7 - 8 + 9

= 115 - 7 - 8

= 115 - 15

= 100
