Answer:

8x - 4y = 3

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 )

Here m = 2 and c = - \frac{3}{4} , then

y = 2x - \frac{3}{4} ← in slope- intercept form

Multiply through by 4 to clear the fraction

4y = 8x - 3 ( subtract 4y from both sides )

0 = 8x - 4y - 3 ( add 3 to both sides )

3 = 8x - 4y , or

8x - 4y = 3 ← in standard form

Which pair of angles are vertical angles?
Irina-Kira [14]

Answer:

Option 4.∠ERT and ∠MRC

Step-by-step explanation:

Definition of vertical angles  : The angles opposite each other when two lines cross. They are always equal.Vertical" refers to the vertex (where they cross).They are also called vertically opposite angles.

Option 1. ∠KRC and ∠CRH

Refer the figure .

These angles does not satisfy the definition of vertical angles . since these angles are not opposite.

Option 2. ∠KRE and ∠ERT

These angles does not satisfy the definition of vertical angles . since these angles are not opposite.

Option 3. ∠MRC and ∠KRM

These angles does not satisfy the definition of vertical angles . since these angles are not opposite.

Option 4.∠ERT and ∠MRC

MT and EC are the two lines that cross each other at vertex R ,

Thus ∠ERT and ∠MRC are opposite to each other .

Hence ∠ERT and ∠MRC are pair of vertcal angles .

Simplify 4( 3+ 7y) + 6(2 - y) if y =2
UkoKoshka [18]

Answer:

68

Step-by-step explanation:

The expression is given as:

4( 3+ 7y) + 6(2 - y)

It is known that y is equal to 2. Therefore, substitute 2 in for y.

4(3+7(2))+6(2-2)

Now, solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction

Solve inside of the parentheses first.

4(3+7(2))+6(2-2)

4(3+14)+6(0)

4(17)+6(0)

Multiply

68+0

Add

Yi Ting weighs 8.3 kg kilograms her older brother is four times as heavy as Yi Ting how much does her older brother weigh in kil
dexar [7]
8.3*4 = 33.2 kg.
Hopefully that is correct
Since Yi Ting weighs 8.3 and her brother is 4 times heavier you would multiply those two numbers to get the answer.
