Answer:

y = -7/4x - 11

Step-by-step explanation:

formula is y = mx + b

m is the slope

b is the y intercept

y = -7/4x -11

which is the first one

Write the equation of the line that is parallel to the given segment and that passes through the point (-3,0).

grandymaker [24]

Answer:

Option (B)

Step-by-step explanation:

In the figure attached,

A straight line is passing through two points (0, 2) and (3, 1).

Slope of this line ( $m_1$ ) = $\frac{y_2-y_1}{x_2-x_1}$

= $\frac{2-1}{0-3}$

= $-\frac{1}{3}$

Let the slope of a parallel to the line given in the graph = $m_2$

By the property of parallel lines,

$m_1=m_2$

$m_2=-\frac{1}{3}$

Equation of a line passing through a point (x', y') and slope 'm' is,

y - y' = m(x - x')

Therefore, equation of the parallel line which passes through (-3, 0) and having slope = $-\frac{1}{3}$ will be,

$y-0=-\frac{1}{3}(x+3)$

$y=-\frac{1}{3}x-1$

Option (B). will be the answer.

Solve for x. 3x/4 - X/12 =7/8 simplify your answer in fraction form

Usimov [2.4K]

Answer:

7/3

Step-by-step explanation:

or, 3x/4 - 7/8 = 7/8

or, 3x/4=7/8+7/8

or, 3x/4 = (7+7)/8

or, 3x/4 = 14/8

or, 3x = (14/8)*4

or, 3x=56/8

or, 3x= 7

or, x=7/3

Amanda uses 1/3 of a cup of milk each time she makes a batch of pancakes. How manybbatches can she make if she only has 11/22 of

kow [346]

Answer:

<u>Amanda can make 1.5 or 3/2 of batches of pancakes with 11/22 of a cup of milk.</u>

Step-by-step explanation:

1. Let's review the information given to us for answering the question correctly:

Amount of milk Amanda use for a batch of pancakes = 1/3 cup

2. How many batches can she make if she only has 11/22 of a cup of milk left?

Let's simplify 11/22, dividing by 11 the numerator and the denominator,

11/22 = 1/2

Now, using the Rule of Three Simple, we can calculate the answer to this question, this way:

Number of batches = (1/2 * 1)/1/3

Number of batches = 1/2 / 1/3

Number of batches = 1/2 * 3/1 (Taking the reciprocal)

Number of batches = 3/2 = 1.5

<u>Amanda can make 1.5 or 3/2 of batches of pancakes with 11/22 of a cup of milk.</u>

Ok this is the last one . lol

Molodets [167]

Answer:

Step-by-step explanation:

Because these two angles are supplementary, their angle measures must add up to 180 degrees. Therefore:

3x+2+2x+23=180

5x+25=180

5x=155

x=31

Hope this helps!
