Write 2x+3(to the power of 2)+x-4(to the power of 2). Then do the equations and you should get 4x+9+2x+16. Combine like terms and that's your answer. I know it might be weird that it's not like 72 or something, but it's math haha. Your answer should be 6x+25! Make sure you understand this before just writing all of this down. Also, don't be afraid to ask your teacher. They are there to help!
Answer:
y=5x+3
Step-by-step explanation:
Hi there!
We are given that a line has a slope of 5, and a y intercept of (0,3)
We want to write the equation of this line in slope-intercept form
Slope-intercept form is written as y=mx+b, where m is the slope and b is the value of y at the y intercept
Since we were given the slope and the y intercept, we can simply substitute these values into the formula to find the equation.
Starting with the slope:
Substitute 5 as m into the equation
y=5x+b
Now for the y intercept:
As stated before, b is the value of y at the y intercept; in this case, b is equal to 3
Substitute 3 as b into the equation.
y=5x+3
Hope this helps!

Ok I will tell you if they are right
Hello!
We put y into the second equation
2x -1(3x - 26) = 19
Distribute the -1
2x - 3x + 26 = 19
Combine like terms
-x + 26 = 19
Subtract 26 from both sides
-x = -7
Since x is negative we can multiply both sides by -1 to make it positive
x = 7
Now we put this into the first equation to find y
y = 3(7) - 26
Multiply
y = 21 - 26
Subtract
y = -5
The answer is -5
Hope this helps!
