Answer:

h(4) = (4)3+2(4) = 20

Step-by-step explanation:

First you input 4 wherever there is an x then you restated the equation with 4 substituted in as x next solve

Write the following inequality in slope intercept form 5x-5y
IceJOKER [234]

Slope intercept form is written as y=mx+b where m is the slope and b is the y-intercept.

So first you need to put it in as y=5x-5y, and turn it into slope intercept form, which will be y=5/6x. Here are the steps:

y=5x-5y

Add 5y to both sides

y+5y=5x-5y+5y

Simplify

6y=5x

Divide both sides by 6

6y/6=5x/6

Simplify

y=5/6x

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great rest of Black History Month! :-)

Which equation represents a line that passes through (5, 1) and has a slope of ?
lys-0071 [83]

Answer:

y - 1 = 5(x - 5)

Step-by-step explanation:

Given the following data;

Points (x, y) = (5, 1)

Slope = ?

From the question, the value of the slope is missing. Hence, let's assume a value of 5.

Mathematically, the equation of a straight line is given by the formula;

y = mx + c

Where;

m is the slope.

x and y are the points

c is the intercept.

To find the equation of line, we would use the following formula;

y - y1 = m(x - x1)

Substituting into the formula, we have;

y - 1 = 5(x - 5)

y - 1 = 5x - 25

y = 5x - 25 + 1

y = 5x - 24 = mx + c

How to find probability from cumulative frequency graph
Salsk061 [2.6K]

Answer:

  find the difference of points on the graph

Step-by-step explanation:

The cumulative frequency graph (CDF) represents the integral of the probability distribution function (PDF). You find the probability that X is in some interval by subtracting the value of the CDF at the low end of the interval from the CDF value at the high end of the interval.

  p(a < x < b) = cdf(b) -cdf(a)

What is the approximate area of the figure?
Valentin [98]

Answer:

Answer D (2206.5 ft^2) is closest to the calculated answer 2206.85 ft^2.

Step-by-step explanation:

We can break up this figure into a 30 ft by 50 ft rectangle and a circle of diameter 30 ft.

The area of the rectangular part is A1 = (30 ft)(50 ft) = 1500 ft^2.

The area of the circular part is A2 = π(15 ft)^2 = 706.9 ft^2

Thus, the total area is approx A1 + A2, or 2206.86 ft^2 (Answer D)
