Definition of vertical line test

Mathematics
1 answer:
Serhud [2]3 years ago
4 0

the vertical line test is a graphical way to determine whether or not the graph is a function of x

if you can draw a vertical line on a graph and cross the graph at least 2 times, the graph is not a function

a function will have 1 y value for every x value, therefore, if we can draw a vertical line (x=c, a constant) that intersects the curve at more than 1 point, then that point where it intersects at more than 1 point is where 1 value of x coresponds to more than 1 value of y and is therefore not a function

Use mental math to approximate what a 15% tip would be for a bill of $31.99.
rodikova [14]

The whole bill is $31.99 that is 100%. You can use mental math to determine exatcly 15% from $31.99:

1. 15%=10%+5%

2. To find 10% from $31.99 you should simply divide $31.99 by ten. Thus, 10% from $31.99 is $3.199.

3. 5% is half of 10%, then 5% from $31.99 is $3.199:2=$1.5995.

4. 15% from $31.99 is $3.199+$1.5995=$4.7985≈$4.80.

Answer: correct choice is B.

4x/3+3=x-2 <br>value of x ?​
Gekata [30.6K]

Answer:

x = - 15

Step-by-step explanation:

Given

\frac{4x}{3} + 3 = x - 2

Multiply through by 3 to clear the fraction

4x + 9 = 3x - 6 ( subtract 3x from both sides )

x + 9 = - 6 ( subtract 9 from both sides )

x = - 15
