Find the GCF for the pair of numbers. 9,4
The GCF of numbers is the greatest common factor of the numbers.
The numbers are given as: 4 and 9.
Factorize both:
[tex]\mathbf{4 = 1 \times 2 \times 2}[/tex]
[tex]\mathbf{9 = 1 \times 3 \times 3}[/tex]
The common factor between both is 1.
So, we have:
[tex]\mathbf{GCF = 1 }[/tex]
Hence, the GCF of 4 and 9 is 1

A. identify the vertex
B. Identify the intercept
C. Write the equation of the graph above
D. Fill in the end behavior:
As x , y ____
As x 3, y ____
E. Identify the domain and range:
We want to identify different things on the given graph.
The solutions are:
A) (3, -1)
B) x = 4
C) x = y^2 + 2y + 4
D) x ⇒ ∞, y ⇒ ∞
x⇒3, y⇒ -1
A) The first thing we want to identify is the vertex, we could say that a vertex is a point of symmetry. (like the minimum/maximum of a parabola). Here we clearly do not have a point of symmetry, as we only have half of a parabola, but if it was a complete one, the vertex would be at the blue point, in (3, -1)
B) This is the point where the graph intercepts the x-axis, x = 4.
C) we want to write the equation, we start with the general parabola, this time as a function of y:
x = a*y^2 + b*y + c
Remember that the x-itercept is at x = 4. then c = 4.
x = a*y^2 + b*y + 4
The y-value of the vertex is -1, while the general y-value of the vertex is:
y = -b/2a = -1
And evaluating the equation in this value, gives us:
x = a*(-1)^2 + b*-1 + 4 = 3
Then we have two equations:
-b/2a = -1
a + -b + 4 = 3
We can rewrite the first one as:
-b = -2a
b = 2a
Now we can replace this on the other equation:
a - 2a + 4 =3
-a + 4 = 3
-a = 3 - 4 = -1
a = 1
And b = 2a = 2*1 = 2
Then the equation of the parabola is:
x = y^2 + 2y + 4
D) We can see that as x grows, y increases, so we can say that:
x ⇒ ∞, y ⇒ ∞
And for the other limit we can see that as x tends to 3, y tends to -1, then:
x⇒3, y⇒ -1

4-2y=-2x
-y+6=x
6x-y-3=0
3y+15x=-15
Answer:
[tex]4 - 2y = -2x [/tex]
subtract the 4 from one side
[tex] - 2y = - 2x - 4[/tex]
divide the -2 from the y and the-2x and 4
[tex]y = - x + 2[/tex]
-y + 6 = x
subtract the 6 and add -6 after the x
[tex] - y = x - 6[/tex]
6x - y - 3 = 0
add the y so it cancels out
y = 6x - 3
3y + 15x = -15
subtract the 15x
3y = -15x - 15
divide the 3
y = -5x -5

2. A line passes through the points (4,7) and
(8, 6). The line also passes through the point
(a, 3.5) for what value of a?
Answer:
a = 18
Step-by-step explanation:
Slope = (7-6)/(4-8) = -1/4
y-intercept = 7 - (-1/4)(4) = 8
Equation of the line: y = - 1/4x + 8
(Substitute y for 3.5. When y is 3.5, what is x)
3.5 = - 1/4x + 8
3.5 - 8 = - 1/4x
(-4.5) / (- 1/4) = x
x = 18

Buffalo Bart’s Endless Wings charges $5.60 for sides and a drink, and then $0.40 per chicken wing. The Spicy Chicken charges $10 for sides and a drink, and then $0.20 per chicken wing. About how many chicken wings must be purchased so that the total cost at Buffalo Bart’s Endless Wings and The Spicy Chicken is the same?
Answer:
22.
Step-by-step explanation:
About 22 chicken wings must be purchased for the total cost at Buffalo Bart’s Endless Wings and The Spicy Chicken to be the same.
Let's represent the number of chicken wings as "x".
The total cost at Buffalo Bart’s Endless Wings would be the sum of the initial cost for sides and a drink ($5.60) and the cost per chicken wing ($0.40 per wing times x):
Total cost at Buffalo Bart’s Endless Wings = $5.60 + $0.40x
The total cost at The Spicy Chicken would be the sum of the initial cost for sides and a drink ($10) and the cost per chicken wing ($0.20 per wing times x):
Total cost at The Spicy Chicken = $10 + $0.20x
To find the number of chicken wings where the total costs are the same, we'll set up an equation:
$5.60 + $0.40x = $10 + $0.20x
Now, solve for "x":
$0.40x - $0.20x = $10 - $5.60
$0.20x = $4.40
Divide both sides by $0.20:
x = $4.40 / $0.20
x = 22
So, about 22 chicken wings must be purchased for the total cost at Buffalo Bart’s Endless Wings and The Spicy Chicken to be the same.

y=rx 1/4/5/5/5
Step-by-step explanation:
Answer:
r = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
The proportional equation is
y = rx ( divide both sides by x )
[tex]\frac{y}{x}[/tex] = r
Substitute any ordered pair from the table
Using (14, 7 ) , then
r = [tex]\frac{7}{14}[/tex] = [tex]\frac{1}{2}[/tex]
