Answer:

Step-by-step explanation:

The vertical line test can be used to decide whether a relation is a function. If you draw a vertical line x = a, the line will intersect the graph of the relation twice for all a > 0. This just means that there are values of x where there is more than one y value, so this is not a function.

Evaluate the expression if r = 12 and t = -6. (t-r)/3

Lynna [10]

Answer:

-6

Step-by-step explanation:

$\frac{(t-r)}{3}$

input the numbers

$\frac{(-6-12)}{3}$

do the problem in the parentheses first

-6-12 = -18

now it becomes

$-\frac{18}{3}$

simplify and you'll get

-6

this is because -18 ÷ 3 =

-6

Jose' traveled from his home in Ocala to Gainesville. Gainesville is 37 miles

Alja [10]

Answer:

The integer -37 represents the direction and the distance covered by Jose from Gainesville to Ocala.

Step-by-step explanation:

The direction is represented by the sign that accompanies the distance, since Jose is returning from Gainesville, then the direction must represented by a minus sign (-), since he is travelling southwards. The distance is the magnitude of the length covered by Jose during his return. Hence, distance is represented by the natural number 37.

Finally, the integer -37 represents the direction and the distance covered by Jose from Gainesville to Ocala.

8x + y = 9 Convert the following equations to standard form

Citrus2011 [14]

Answer:

x=1/8y+9/8

y=y=−8x+9

Step-by-step explanation:

Let's solve for y.

8x+y=9

Step 1: Add -8x to both sides.

8x+y+−8x=9+−8x

y=−8x+9

Let's solve for x.

8x+y=9

Step 1: Add -y to both sides.

8x+y+−y=9+−y

8x=−y+9

Step 2: Divide both sides by 8.

8x/8=−y+9/8

x=−1/8y+9/8

Which are the solutions of the equation 4x^2-7x=3x+24

vfiekz [6]

Answer:

x=4

Step-by-step explanation:

Because 4 to the power of 2 is 16.

Then, you subtract: 16x - 7x

Then, what you are going to see is 9x=3x+24

So, you subtract: 9x - 3x

Finally, you will have 6x=24... You divide: 24/6 and the answer is x=4.
