Vertical Line Test - A function's x-values must have only 1 y-value corresponding to it. If the function fails to pass this, it is not a function.Step-by-step explanation:
When we apply the Vertical Line Test to the 1st graph, it does not pass it. Therefore, the 1st graph is not a function.
When we apply the Vertical Line Test to the 2nd graph, it does not pass it. Therefore, the 2nd graph is not a function.
When we apply the Vertical Line Test to the 3rd graph, it does not pass it. Therefore, the 3rd graph is not a function.
When we apply the Vertical Line Test to the 4th graph, it does pass it. Therefore, the 4th graph is a function.

[tex]2x + 3 = 45[/tex]
Subtract sides 3
[tex]2x + 3 - 3 = 45 - 3[/tex]
[tex]2x = 42[/tex]
Divide sides by 2

Thus the correct answer is the last option.
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
Answer:
The value of x is 21.
Step-by-step explanation:
The angles of a triangle all add up to 180 degrees. One side has an angle of 90 (right angle). So to find the others you would subtract 180 from 90 and divide it by 2. And you will get 45, so both acute angles will be 45 degrees.
If you subsitute 21 for x you will get 2*21 + 3 = 45, which is true (42 + 3 = 45)

Write sin(x+1) in terms of unshifted sine and cosine. Write your answer using decimals.
Please provide explanation, I’m confused.
Answer: sin(x + 1) = 0.841*cos(x) + 0.540*sin(x)
Step-by-step explanation:
Here we can use the relation:
Sin(a + b) = sin(a)*cos(b) + sin(b)*cos(a)
In this case we have:
sin(x + 1)
This means that the graph of sin(x) is shifted one unit to the left.
But we can write this, using the above relation, as:
sin(x + 1) = sin(x)*cos(1) + sin(1)*cos(x)
Now we have no longer a shift, and we can replace:
sin(1) = 0.841
cos(1) = 0.540
Then:
sin(x + 1) = 0.841*cos(x) + 0.540*sin(x)

write an equation of the line that passes through (-1, 3) and has a slope of -4
Answer:
y = -4x - 1
Step-by-step explanation:
We are given the slope so we can find the y intercept using slope intercept [ y = mx + b ]
y = -4x + b
3 = -4(-1) + b
3 = 4 + b
-1 = b
Now, put everything we know and solved for back into the formula.
y = -4x - 1

Najat is selling raffle tickets. The table shows the cost (in dollars) of buying different numbers of tickets.
Using x for the number of tickets and y for the cost, do the following.
Write an equation relating x and y
Answer:
The equation relating x and y is: y=4x
Step-by-step explanation:
Let x represent number of tickets
and y represent cost
a) Plot the ordered pairs
The ordered pairs (1,4),(2,8),(3,12),(4,16) is plotted in figure attached.
b) Write an equation relating x and y
y= 4x
Now checking by putting values of x to see, if we get values of y
if x=1, then y=4x => y=4*1 =>y=4
if x=2 then y=4x => y=4*2 =>y=8
if x=3 then y=4x => y=4*3 =>y=12
So, we get same values as table.
The equation relating x and y is: y=4x

The area of the postcard pictured below is 24 square inches. What is the width b of the message section (in inches)? Pick the equation that would best model this situation.
A. 4(b + 3) = 24
B. 3(4 + b) = 24
C. 4(b - 3) = 24
D. 3(b - 4) = 24
Answer:
Step-by-step explanation:
4(b + 3) = 24
Answer:
A. 24 = 4(b + 3)Step-by-step explanation:
Area is equal to length times width. In this case, the length is b + 3 (since both b and 3 are part of the width, with the length being 4.
Substitute into the equation for area:
a = lw
a = 4(b + 3)
The area is 24, so the final answer is:
