The number in parenthesis after f is the x coordinate. Basically, it says which y coordinate is tied with an x value. In choice a, it says that when x is 0 y is 3, etc.

So, you can look at the graph to see which answer choice has a point from the graph. Choice a says (0,3), and that does not match. Choice b says (5,-1) and that does match. So the answer is B.

Straight line A has the equation y = 3x + 2. Find the equation of the line parallel to A and goes

arlik [135]

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 )

y = 3x + 2 ← is in slope- intercept form

with slope m = 3

Parallel lines have equal slopes , then

y = 3x + c ← is the partial equation

To find c substitute (3, 8 ) into the partial equation

8 = 9 + c ⇒ c = 8 - 9 = - 1

y = 3x - 1 ← equation of parallel line

Answer:

x = 17°

Step-by-step explanation:

<u>Angles And Parallel Lines </u>

If two parallel lines are crossed by a third line, corresponding angles are congruent. Also, consecutive angles are supplementary

We can clearly see in the image provided, being w and b parallel, that the corresponding angles (4x-3) and 65° are congruent. We can express that relation as

$4x-3=65$

Operating

$4x=65+3=68$

$x=\frac{68}{4}=17$

So the value of the angle x is 17°

USPshnik [31]

Answer:

The answers would be as follows:

Step-by-step explanation:

We can tell that the first two have an infinite number of solutions because when we try to solve, we get a true statement. The first one is done for you below.

-6x + 7 = -6x + 7 ------> Add 6x to both sides

7 = 7 (TRUE STATEMENT)

We can tell the next two have no solution due to the fact that they develop a false statement when trying to solve.

-3x + 7 = 3x + 7 ----> Subtract 7 from both sides

-3x = 3x ---> Divide by 3

-x = x (UNTRUE STATEMENT)

One week, London earned $313.50 at her job when she worked for 15 hours. If she is paid the same hourly wage, how many hours wou

kicyunya [14]

Answer:

31 hours

Step-by-step explanation:

First you take 313.50 divide that by 15 get 20.9 per hour

Then you take 647.90 and divide that by 20.9

So then you're left with 31 as your answer.
