The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.
Answer:
The roots of a function are the x-intercepts.

Solve for X
6+3x=12x-5
Answer:
x= 11/9
Step-by-step explanation:
6 +3x = 12x -5
-6 -6
3x = 12x -11
-12x -12x
-9x = -11
/-9 /-9
x= 11/9
Solve each of the following system of equations by substitution!!!
x-5y=-49
y=-2x+1
Answer:
x = -4, y = 9
or
(-4, 9)
Step-by-step explanation:
x - 5y = -49
y = -2x + 1
substitute y for -2x + 1
x - 5(-2x + 1) = -49
x + 10x - 5 = - 49
add 5 to both sides
x + 10x - 5 + 5 = - 49 + 5
x + 10x = -44
11x = -44
divide both sides by 11
11x/11 = -44/11
x = -4
substitute x for -4 in any of the original equations
y = -2x + 1
y = -2 * -4 + 1
y = 8 + 1
y = 9
Answer:
x = -4, y = 9 or (-4,9)

Diane has $20 in a savings account that earns 5 % annually. How much will she earn in interest in 1 year?
Answer:
$21
Step-by-step explanation:
Given data
Principal= $20
Rate = 5%
time= 1 year
Required
The final amount A
Applying the simple interest formula
A= P(1+rt)
substitute
A=20(1+0.05*1)
A=20(1.05)
A=20*1.05
A=$21
Hence she will earn $21
If the points (2, 4), (5, k), and (8, 20) are on the same line, what is the value of k?
Answer:
k = 12
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 4) and (x₂, y₂ ) = (8, 20)
m = [tex]\frac{20-4}{8-2}[/tex] = [tex]\frac{16}{6}[/tex] = [tex]\frac{8}{3}[/tex]
Repeat using (5, k) as one of the points and equate to [tex]\frac{8}{3}[/tex]
(x₁, y₁ ) = (2, 4) and (x₂, y₂ ) = (5, k) , then
m = [tex]\frac{k-4}{5-2}[/tex] = [tex]\frac{k-4}{3}[/tex] = [tex]\frac{8}{3}[/tex] ( cross- multiply )
3(k - 4) = 24 ( divide both sides by 3 )
k - 4 = 8 ( add 4 to both sides )
k = 12

Answer:
1. Well, to cross multiply them you multiply the numerator in the first fraction times the denominator in the second fraction, then you write that number down. ... The reason we cross multiply fractions is to compare them. Cross multiplying fractions tells us if two fractions are equal or which one is greater.
2. Cross multiplying fractions to find a missing numerator or denominator for equivalent fractions works because it is a shortcut for rearranging to isolate the variable.

During training, a hurdler wants to raise the height of the hurdles from the high school standard of 39 inches to the NCAA standard of 42 inches. His best race form last season included a clear over 39-inch hurdle that was modeled by h(t)= -0.025t(t-25), where t is time (in tenths of a second) after his lead leg left the track and h is the height (IN FEET)
a) Sketch the graph. Label the axes.
b) If he runs as well as his best race last year, will this hurdler clear the new height? Why or Why not?
Answer:
I cant sketch the graph on brainly

Paulo and Marie are collecting quarters. The number of quarters Paulo has is 3 times 5 fewer than the number of quarters Marie has. Let m be the number of quarters Marie has. What expression represents the number of quarters Paulo has?
Answer:
Paulo = 3m - 5
Step-by-step explanation:
m = number of quarters Marie has
The number of quarters Paulo has is 3 times 5 fewer than the number of quarters Marie has
3 times number of quarters Marie has = 3 * m
= 3m
5 fewer than the number of quarters Marie has
3m - 5
Paulo = 3m - 5
