The true statement is that Stephen's factored expression is incorrect
The expression is given as:
[tex]x^2-10x+21[/tex]
Start by expanding the equation
[tex]x^2-10x+21 = x^2-7x - 3x+21[/tex]
Factorize the equation
[tex]x^2-10x+21 = x(x-7) - 3(x-7)[/tex]
Factor out x - 7
[tex]x^2-10x+21 = (x-3)(x-7)[/tex]
The above expression shows that:

For the question on the left:
The number line counts by 0.3 every time. For each value in front of -0.5, just add 0.3 and that will be the next value.
For the question on the right:
-1/3 > -5.4 , because negative numbers closer to zero are bigger.

how many solutions does the system of equations have?(1 point)
3x=-12y+15 and x+4y=5
A-one
B-two
C-infinitely many
D-none
Answer:
c
Step-by-step explanation:
First, I'll isolate the x in x+4y=5 to match with the other equation.
The new equation would be x= -4y+5
Next, we will multiply one equation by 3 and the other by -1 for both to match with the other.
-1(-12y + 15 = 3x )
3(-4y + 5 = x)
The new equations would be :
12y - 15 = -3x
-12y + 15 = 3x
Add the equations and you get
0 = 0
The equation has an infinite amount of solutions

what is the slope of the line with the following equation? (y-3)= -4(x-5)
Answer:
slope = - 4
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 3 = - 4(x - 5) ← is in point- slope form
with slope m = - 4
Answer:
-4
Step-by-step explanation:
First express it in the form of y=mx+b where m is the slope and b is the y-intercept
y-3=-4x+20
y=-4x+20+3
y=-4x+23 then m=-4 which is the slope

The length of the rectangle is what cm ?
the width of the rectangle is
what cm.?
Answer:
Step-by-step explanation:
the perimeter P=2(L+W)=54
