A quadrilateral has vertices at (1,1), (4,2), (0,4), and (5,5). What is the perimeter of the quadrilateral?

Since 0 < y < 1.5, hence the coordinate (1,1) is a solution

Given the following inequality expression

y>0

y< 2.5x - 1

Wee are to check if (1, 1) is a solution to the systen of equation

If x = 1

y < 2.5(1) - 1

Y < 2.5 - 1

y < 1.5

Since 0 < y < 1.5, hence the coordinate (1,1) is a solution

Answer:

y = (9/4)x + 2, given that I've assume the correct meaning of "-5x4."

Step-by-step explanation:

A parallel line has the same slope as the reference line,

The reference line is 9x-4y = -5x4, as written.  I'm not sure the 4 belongs, but I'll assume it is written correctly.  I'm not sure if the term -5x4 is meant to mean -5x^4, -20x or -20.  I'll assume -20:

9x-4y = -20

Put the equation into standard slope-intercept form:  Y = mx + b, where m is the slope and b is the y-intercept (the value of y when  x = 0).

-4y = -9x - 20

y = (9/4)x + 5

This line has a slope of (9/4).  The parallel line will have the same slope.

y = (9/4)x + b

We can find a value of b that would shift this line to include (4,7) by using this point in the equation:

y = (9/4)x + b

7 = (9/4)(4) + b

7  = 9 + b

b = 2

The equation of a line parallel to the reference line is y = (9/4)x + 2

The graph of the function f(x) = x³ – 2x² – 19x + 20 passes through the  x-axis at  –4, 1, and 5.

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The function is given as

f(x) = x³ – 2x² – 19x + 20

By hit and trial. Let x = 1, we have

f(x) = 1³ – 2(1)² – 19(1) + 20 = 0

Then the equation will be

f(x) = (x – 1)(x² – x – 20)

f(x) = (x – 1)(x – 5)(x + 4)

Then the graph of the function passes through x-axis at  –4, 1, and 5.

The graph is shown below.

Answer:

Between 2 1/2 and 3 ounces

Step-by-step explanation:

Since 1/3 is lower than 3/4, 5 1/3 - 2 3/4 must be lower than 3, but higher than 2.

So, we can eliminate C and D.

A's range is too small, so we can select B.

Answer:

First we must use the property of the sum of perfect squares:

X^2 -14x +y^2 +10y+65 =0

Adding 7^2 and -7^2

x^2 -14x+7^2-7^2 +y^2+10y+65=0

x^2 -2.7x +7^2 -49 +y^2+10y+65=0

(X-7)^2 +y^2+10y+16=0

Adding 5^2 and -5^2

(X-7)^2 +y^2 +10y+5^2-5^2+16=0

(X-7)^2 +y^2+2.5y+5^2 -25 +16=0

(X-7)^2+ (y+5)^2 -9 = 0

(X-7)^2 +(y+5)^2 = 9

(X-7)^2+(y+5)^2 = 3^2

Center = (7, -5)

R = 3

The circle is in the 4 quadrant.

Rounding off is basically a approximate value written in compact form for our convenience when precise  accurate result is not that necessary.

A decimal is a point or a dot separating the whole part and the fractional part of the number.Now rounding off numbers to certain decimal places has a condition if the digits just after the decimal is more than half we take the upper value if itis less than half we take the lower value.

Given in this question let's go by rounding off from 1 place to 4 for better understanding.

rounding off 24513589 to one decimal place = 2451359.0

rounding off 2451359.0 to one decimal place = 245136.0

rounding off 245136.0 to one decimal place = 24514.0

rounding off 24514.0 to one decimal place  = 2451.0

Answer:

f(x) = 2x+5

Step-by-step explanation:

As you know, a student ticket is one item, and you only need one of these to enter a football game. We will assume he is by himself and without friends. There are items he can buy for $2 each at the concession stand.

With what we know, we can conclude that the total cost to attend the football game could be a function.

The function will be

f(x) = 2x + 5

This is because you buy the ticket one time and buys x items, which is modeled by the function.

I'm sorry that I can't send any links, but if you go to desmos graphing calculator, you can find type the function out and get the graph of the function. Remember to look only at the first quadrant!

x < 22.5; Samuel has less than 22.5 minutes to finish the race in the estimated time.

The given inequality is-

[tex]10x < 33[/tex]

From here, we define the variable x.

x = Number of the minutes left for the race

From here we can find the value of x

We have then:

[tex]x < 33-10.5[/tex]
