Determine whether the following graph represents a function

Answer:

Janiya has a speed of [tex]2\frac{2}{5}[/tex] miles per hour.

Step-by-step explanation:

Given that:

Distance covered = 4/5 of a mile

Time taken to cover the distance = 1/3 of an hour

Speed is defined as the distance travelled in a certain time.

Speed of Janiya = [tex]\frac{Distance}{Time}[/tex]

Speed of Janiya = [tex]\frac{\frac{4}{5}}{\frac{1}{3}}[/tex]

Speed of Janiya = [tex]\frac{4*3}{5*1}[/tex]

Speed of Janiya = [tex]\frac{12}{5}[/tex]

Speed of Janiya = [tex]2\frac{2}{5}[/tex] miles per hour

Hence,

Janiya has a speed of [tex]2\frac{2}{5}[/tex] miles per hour.

Answer:

108 sq in.

Step-by-step explanation:

The ratio of the areas is the square of the ratio of the sides.

Side ratio     1:3

Area ratio    1:9

The side of the larger trapezoid is 3 times the side of the smaller trapezoid.

The area of the larger trapezoid is 9 times the area of the smaller trapezoid.

9 * 12 sq in. = 108 sq in.

Answer:

B.37.5%

Step-by-step explanation:

Step one:

given

The sale price of $25

The original cost of the sweater was $40

Required:

The percent discount

Step two:

% discount= change in price/original price *100

%discount = 40-25/40 *100

% discount= 15/40*100

% discount = 0.375*100

% discount =37.5%

The decimal i.e. less than 3.19 is 3.179.

As we can see that from the options 3.2, 3.291 and 3.1911 is more than 3.19.

Therefore 3.179 should be less than 3.19.

Answer:x=6

Step-by-step explanation:

So if y is 0, that’s 8(y) which is 0. That means the equation is 2x=12, which means x is 6

My comments don’t work! But it’s (6,0)

Answer:

yes it can

Step-by-step explanation:

Answer:

Yes, m can be a fraction.

Step-by-step explanation:

m in y=mx+b stands for slope, and slope is rise/run, so it most definitely can be a fraction. BUT, keep it as 5/4 or 1.25 when writing it so you don't confuse yourself next time ;)

Explanation:

The same tickmarks on each side of the triangle tells us that all three sides are the same length. This triangle is equilateral.

All equilateral triangles have each of their three angles at 60 degrees (they are considered equiangular). This is because 60+60+60 = 180.

Set 2x+32 equal to 60 and solve for x

2x+32 = 60

2x = 60-32

2x = 28

x = 28/2

x = 14

As a check,

2x+32 = 2*14+32 = 28+32 = 60

which helps confirm the answer.

28.3

Answer:

y = 410

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Step-by-step explanation:

Step 1: Define

y = 23x - 4

x = 18

Step 2: Evaluate

Answer:

y = 410

Step-by-step explanation:

y = 23x - 4    If x = 18

y = (23*18) - 4

y = 414 - 4

y = 410
