Solve the system of equations using subsititution.
y = 2x - 3
y + 5 = 3x
Answers
Answer:
(2,1)
x = 2
y = 1
Explanation:
Check the image
Answer:
(2,1)
Step-by-step explanation:
Since we already have an equation for y, all we need to do is plug that into y in the other equation.
y + 5 = 3x
(2x - 3) + 5 = 3x
2x - 3 + 5 = 3x
2x + 2 = 3x
2 = x
Now that we know y, we just need to plug the value of x into the equation.
y = 2(2) - 3
= 4 - 3
= 1

A polynomial is a factor of another polynomial if when divided they have a remainder of zero. True or False.
Answers
Answer:
True
Step-by-step explanation:
The Factor theorem states that for any polynomial f(x) if f(c)=0 then x-c is a factor of the polynomial f(x).
If any polynomial f(x) is divided by x-a and remainder is 0 that means f(a)= 0 .In other words we can say x-a is a factor of the polynomial f(x).So the statement :If a polynomial is divided by (x-a) and the remainder equals zero then (x -a) is a factor of the polynomial is True.

What is the slope of this line?
Answers
The slope of horizontal lines is zero because they are straight with no curve.
The slope is calculates using the rise over the run.
Rise= How many units we move up. Here we move 0 units.
Whatever the run is (NOT 0) if we divide 0 by the run, we will get 0.
Diagonal lines always have slope.

Answers
Answer:
[tex](5, -5/2)[/tex]
Step-by-step explanation:
The midpoint of any line segment is the average of the x- and y-values of the two endpoints.
Therefore, the midpoint of [tex]AB[/tex] is [tex]((3+7)/2, (-8+3)/2)=(10/2, -5/2)=(5, -5/2)[/tex].
So, the answer is [tex]\boxed{(5, -5/2)}[/tex] and we're done!

The revenue from selling x shirts is f(x) = 11x. The cost of buying x shirts is cx) = 6 x + 20. The profit from selling x shirts is p(x) = HX) - cx). What is p(x)?
Answers
Answer:
P(x) = 5(x) - 4(x) as 20(x) = 4(5) is added to 5(x) = 25 -20 = 5 so profit fro one shirt is set = 1 as 5 * 1 = 5 and (x) = 5
Step-by-step explanation:
11x - 6( ?)+20 = p(?) -H(?) - c (?) = 11x - p(x) = HX) - cx) = 6(x )+20 = 11x-6x -20 = 5x -20 = P(x) = 5(x) - 4(x)
Taylor states that 2,800,000 in scientific notation is 2.8 x 10 -6 because the number has six places to the right of the 2. Is Taylor's reasoning correct?
Answers
Scientific Notation is the way of writing a number or expressing them in a shorter or more compact way.
No, Taylor's resoning is incorrect because 2,800,000 = [tex]2.8 * 10^{6}[/tex]
From the question, we are given:
2,800,000 .
2,800,000 in scientific notation is [tex]2.8 * 10^{6}[/tex].
The reason the power is not to the negative 6 is that we are moving from the right-hand side to the left-hand side 6 times.
Therefore, Taylor's reasoning is incorrect.
