3 < 9 - 7
Simplify (9-7)
9 - 7 = 2
"The crocodile ALWAYS eats the bigger umber" in true equations
3 < 2 reads: 3 is less than 2

How do I Solve 75% of x =42
Answer:
[tex]=31.5[/tex]
Step-by-step explanation:
Given the following question:
75% of 42
In order to find the answer, we use the formula to calculate percentage.
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{75\times42}{100} =75\times42=3150\div100=31.5[/tex]
[tex]=31.5[/tex]
Which means 75% of 42 is "31.5."

6x^2+9x+3 factor trinomial
Answer:
(x+1) ( x+(1/2))
Step-by-step explanation:
6x² +9x +3 , divide all terms by 6 to have the first term with coefficient 1
x² + (9/6)x + (3/6) , simplify the fractions
x² + (3/2)x + (1/2)
To get x² the first term we should have
(x.....)(x.....)
To get the last term (1/2) we should have
(x...1)(x...(1/2))
To get the middle term (3/2)x we should have
+1*x +(1/2) x = (2/2)x +(1/2)x = (3/2)x
(x+1) ( x+(1/2))

Which statements correctly describe the graph of the function f(x) = x3 – 2x2 – 19x 20? Select three options.
The graph of the function f(x) = x³ – 2x² – 19x + 20 passes through the x-axis at –4, 1, and 5.
What is a factorization?It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The function is given as
f(x) = x³ – 2x² – 19x + 20
By hit and trial. Let x = 1, we have
f(x) = 1³ – 2(1)² – 19(1) + 20 = 0
Then the equation will be
f(x) = (x – 1)(x² – x – 20)
f(x) = (x – 1)(x – 5)(x + 4)
Then the graph of the function passes through x-axis at –4, 1, and 5.
The graph is shown below.

Javier goes to a football game. He pays $5 for a student ticket and $2 per item bought at the concession stand. Is the total cost to attend the football game a function of the number of items purchased at the concession stand? Use a graph to help explain your answer. Show your work explain your answer
Answer:
f(x) = 2x+5
Step-by-step explanation:
As you know, a student ticket is one item, and you only need one of these to enter a football game. We will assume he is by himself and without friends. There are items he can buy for $2 each at the concession stand.
With what we know, we can conclude that the total cost to attend the football game could be a function.
The function will be
f(x) = 2x + 5
This is because you buy the ticket one time and buys x items, which is modeled by the function.
I'm sorry that I can't send any links, but if you go to desmos graphing calculator, you can find type the function out and get the graph of the function. Remember to look only at the first quadrant!

Answer:
g(x) = (x + 3)²
Step-by-step explanation:
the equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
here (h, k ) = ( - 3, 0 ) , then
g(x) = (x - (- 3))² + 0 , that is
g(x) = (x + 3)²

(a) The interior angles of any triangle sum to 180° in measure. So
(8x + 2) + 70 + 60 = 180
Solve for x :
8x + 132 = 180
8x = 48
x = 6
(b) Evaluate 8x + 2 when x = 6 :
8•6 + 2 = 48 + 2 = 50

Miguel is making trail mix. He uses 5 1/3 ounces of nuts and 2 3/4 ounces of raisins. Which of these is a reasonable estimate for how many more ounces of nuts than raisins Miguel uses?
A: Between 2 and 2 1/2 ounces
B: between 2 1/2 and 3 ounces
C: between 3 and 3 1/2 ounces
D: between 3 1/2 and 4 ounces
Answer:
Between 2 1/2 and 3 ounces
Step-by-step explanation:
Since 1/3 is lower than 3/4, 5 1/3 - 2 3/4 must be lower than 3, but higher than 2.
So, we can eliminate C and D.
A's range is too small, so we can select B.
When graphed, the circle with equation
2x² + y2 + 14x + 8y + 20 = 0
Will lie ENTIRELY in Quadrants…
Answer:
First we must use the property of the sum of perfect squares:
X^2 -14x +y^2 +10y+65 =0
Adding 7^2 and -7^2
x^2 -14x+7^2-7^2 +y^2+10y+65=0
x^2 -2.7x +7^2 -49 +y^2+10y+65=0
(X-7)^2 +y^2+10y+16=0
Adding 5^2 and -5^2
(X-7)^2 +y^2 +10y+5^2-5^2+16=0
(X-7)^2 +y^2+2.5y+5^2 -25 +16=0
(X-7)^2+ (y+5)^2 -9 = 0
(X-7)^2 +(y+5)^2 = 9
(X-7)^2+(y+5)^2 = 3^2
Center = (7, -5)
R = 3

Line K has the equation 9x-4y=-5x4.
Line L is parallel to line K, but line L passes through the point (4,7).
The equation for L in slope-intercept form is_______
Answer:
y = (9/4)x + 2, given that I've assume the correct meaning of "-5x4."
Step-by-step explanation:
A parallel line has the same slope as the reference line,
The reference line is 9x-4y = -5x4, as written. I'm not sure the 4 belongs, but I'll assume it is written correctly. I'm not sure if the term -5x4 is meant to mean -5x^4, -20x or -20. I'll assume -20:
9x-4y = -20
Put the equation into standard slope-intercept form: Y = mx + b, where m is the slope and b is the y-intercept (the value of y when x = 0).
-4y = -9x - 20
y = (9/4)x + 5
This line has a slope of (9/4). The parallel line will have the same slope.
y = (9/4)x + b
We can find a value of b that would shift this line to include (4,7) by using this point in the equation:
y = (9/4)x + b
7 = (9/4)(4) + b
7 = 9 + b
b = 2
The equation of a line parallel to the reference line is y = (9/4)x + 2

The relationship is how when temperatures are rising the sweaters sold go down but when its colder the sweater sales go up.
and for b I don't know but I do know that the line of best fit goes well in points 12,0 (15,4) (7,10)
if you could just find the slope and y intercept and show your work
Answer:
See below.

Help me answer the three questions
A manufacturer makes rectangular blankets in servers style and sizes. The outline of a popular blanket is size A is shown below.
Length = 3x - 7
Width = 2x - 3
A) write a polynomial expression, in simplified form, that represents the perimeter of the blanket. Show work below
B) write a polynomial expression, in the simplest form, that represents the area of the blanket. Show work below
C) the same blanket style in Size B has width 2x + 10 and length 4x - 10. Wrote a polynomial expression, in simplest form that expresses the difference in the areas of blanket a and b. Show work below
Answer:
A) Perimeter of the blanket = 2(Length + Width)
<=> 2[(3x - 7) + (2x - 3)]
<=> 2(3x - 7 + 2x - 3)
<=> 2(5x - 10)
<=> 10x - 20
B) Area of the blanket = Length * Width
<=> (3x - 7)(2x - 3)
<=> [tex]6x^{2}[/tex] - 9x - 14x + 21
<=> [tex]6x^{2}[/tex] - 23x + 21
C) Difference between the areas of the two blankets = (L1 * W1) - (L2 * W2)
<=> [(3x - 7)(2x - 3)] - [(2x + 10)(4x - 10)]
<=> (6[tex]x^{2}[/tex] - 23x + 21) - (8[tex]x^{2}[/tex] - 20x + 40x - 100)
<=> 6[tex]x^{2}[/tex] - 23x + 21 - 8[tex]x^{2}[/tex] + 20x - 40x + 100
<=> -2[tex]x^{2}[/tex] - 43x + 121
Hope it helps you!
