They are both labeled as 3 feet, so both must be equal, unless you doubt the labeling. Unless that is so, then both segments are equal.

point slope form of a line

y-y1 = m(x-x1)

y-4 = -3(x--5)

y-4 =-3(x+5)

to change to slope intercept form

dstribute

y-4 = -3x-15

add 4 to each side

y = -3x-15+4

y = -3x-11

Answer: For part A, the formula for the employee's pay is Pay = hourly rate times hours . P = r × h The equation is P = 13h To find how many hours are required to earn a given amount, fill in given values and solve for the missing variable . 7800 = 13h h= 7800/13 600 hours needed.

For part B, the formula for this employee's pay is Pay = Bonus + hourly rate times hours . P = b + rh

330 = 90 + r(24) 330 - 90 = 24r . 240 = 24r 240/24 = r . r = 10

The employee's pay rate is $10 per hour.

If the graph of the function f has a multiple zero at x = 2, what is a possible exponent of the factor x - 2? Justify your reaso

melomori [17]

Answer:

$(x-2)^2$

The exponent is 2.

Step-by-step explanation:

Remember multiplicity rules:

If a factor has an odd multiplicity (e.g. it is raised to 1, 3, 5...) then it will cross the x-axis.
If a factor has an even multiplicity (e.g. it is raised to 2, 4, 6...) then it will bounce off the x-axis.

At x=2, we have the factor (x-2).

From the graph, we can see that the graph bounces off at that point.

Hence, the multiplicity of (x-2) must be even.

Therefore, a possible exponent for the factor (x-2) is 2. Any even number will suffice.

What equation is being graphed?

Alex

Answer:

D. y-4= -3/2(x+5)

Step-by-step explanation:

Firstly, taking two valid ordered pairs from the graph:

(-2,4) and (2,-2)

Using Delta y over Delta x, we are able to obtain m as -3/2

Next,

The following is the point-slope formula:

y-y₁=m(x-x₁)

Based on the graph, (4,-5) can be spotted as a definite ordered pair

Therefore, y-4= -3/2(x+5) fits the graph best and has the appropriate m value.
