Answer:

-3, -2, -0.8, 0.8, 7

Answer:

21

Step-by-step explanation:

f(x) =x^2 - 6x + 21

f(xl =0

Answer:

substitute 0 for x

f(0) = 0^2 - 6(0) + 21

0. = 0 - 0 + 21

0. = 21

Answer:

To draw the graph of linear equation of the form

 y-a=m (x-b)

We will first write it in slope intercept form which is of the form

It will cut x axis and y axis at ,  respectively.

As Euclid postulate States that, Unique equation of line can be Determined by two points, So join these two points. And Infinite number of points lie on a line.

Graph B

Step-by-step explanation:

The graph that represents the equation y - 2 = 3(x - 1) is: B. Graph B.

y = mx + b is used to represent the equation of a line in slope-intercept form, where, m is the slope and b is the y-intercept of the line.

Given the equation, y - 2 = 3(x - 1), rewrite the equation in slope-intercept form:

y - 2 = 3x - 3

y = 3x - 3 + 2

y = 3x - 1

The slope (m) is 3 and the y-intercept (b) is -1. Thus, the graph that has a slope of 3 and a y-intercept as -1 is graph B.

Answer: $56.20

Step-by-step explanation:

Both the tax and the tips will be based on the total cost:

Tip = 43.57 * 20%

= $8.71

Tax = 43.57 * 9%

= $3.92

Total = Cost + Tip + Tax

= 43.57 + 8.71 + 3.92

= $56.20

Answer:

The volume of the cylinder is 3,080 cm^3

Step-by-step explanation:

Mathematically, we have the volume calculated as;

V = pi * r^2 * h

r = radius = 14 cm/ 2 = 7 cm (14 cm is the diameter and the radius is half the diameter)

h = height = 20 cm

Substituting these values;

V = 22/7 * 7^2 * 20

V = 22 * 7 * 20

V = 3,080 cm^3

Answer:

Mrs. Lopez made 50 quarts of sweet tea

Step-by-step explanation:

A gallon and a quart are two of the five US standard volumes of measurement. In relation to litres, a quart is 946.352946 millilitres while a gallon is  3.7854118 litres.

The relationship between The gallon and The quarts is given as 4:1

This means that for every 4  quarts, there is 1 gallon.

Now, let us find the number of quarts in 12¹/₂ gallons as follows:

1 gallon = 4 quarts

∴ 12¹/₂ gallons = 12¹/₂ × 4 quarts

converting the mixed fraction to improper fraction and multiplying:

= ²⁵/₂ × ⁴/₁

[tex]= \frac{25 \times 4 }{2 \times 1} = \frac{100}{2} \\\\= 50\ quarts[/tex]

Answer:

x = 6

Step-by-step explanation:

The median is half the sum of the parallel bases , then

[tex]\frac{2x+4+10x-50}{2}[/tex] = 13 ( multiply both sides by 2 to clear the fraction )

12x - 46 = 26 ( add 46 to both sides )

12x = 72 ( divide both sides by 12 )

x = 6
