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

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)

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

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

Which line is parallel to the line given y=-5/2x-7

Step-by-step explanation:
can't rely see it lol
Answer:
x = 60
Step-by-step explanation:
Answer:
x = 60°
Step-by-step explanation:
we know that triangles have 180 degrees so we can set up an equation:
86 + 34 + x = 180
now we subtract the sum of 86 and 34 from both sides to get a final answer:
x = 60
so lets plug our x value into the previous equation to check our answer:
86 + 34 + 60 = 180
when we add these numbers together, the equation checks out so we know our answer is correct.

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.
