Select THREE statements that are true about the graph.
A. There is a proportional relationship between the number of peaches and the cost because a
line can be drawn passing through the origin and connecting all the points shown.
B. There is a proportional relationship between the number of peaches and the cost because the
X-value is always greater than the y-value.
C. The point (1, 0.75) can be used to represent the unit rate of 0.75 dollars per peach.
D. The point (1, 0.75) can be used to determine the total cost by subtracting 0.25 from the
number of peaches.
E. The point (4, 3) represents 4 peaches at a cost of $3.

A North Dakota license plate has six characters: 3 digits followed by 3 letters (e.g. 123AAA). Any number from 0 to 9 can be used as a digit. Any of the 26 letters from A to Z can be used as a letter.
How many different North Dakota license plates can be issued?
Answer:
17,576,000
Step-by-step explanation:
Since, there is 3 digits, 0-9, you would have 10 numbers total to choose from. As well as the 26 letters. Since you need three of each, you multiply.
10*10*10*26*26*26
=
17576000
twice the sum of a number and ten
Answer:
2(x+10)
Step-by-step explanation:
Well since sum is addition and the number and 10 are the sum, let’s make the “number“ (x) and add em up. 10+x.
Now we gotta double that sum which is basically
2(10+x)
What is the solution to the equation?
√2x+10−6=2
*Picture of the Problem Below*
Answer:
x = 27
Step-by-step explanation:
Given
[tex]\sqrt{2x+10}[/tex] - 6 = 2 ( add 6 to both sides )
[tex]\sqrt{2x+10}[/tex] = 8 ( square both sides )
2x + 10 = 8² = 64 ( subtract 10 from both sides )
2x = 54 ( divide both sides by 2 )
x = 27
The roots of the equation x^2+bx+x=0 are -4 and 2.
Find B and C
Answer:
b = 2, c = - 8
Step-by-step explanation:
Given x = a is a root then (x - a) is a factor
Here the roots are x = - 4 and x = 2 , then the corresponding factors are
(x + 4) and (x - 2)
The equation is then the product of the factors , that is
(x + 4)(x - 2) = 0 ← expand factors using FOIL
x² + 2x - 8 = 0
with b = 2 and c = - 8

B) 5p^3 + 7p - 4
Step-by-step explanation:
This can be confusing because of the parenthesis, but to answer it all you have to do is group the like terms. Rearrange the problem so it looks like this:
3p^3 + 2p^3 + 5p + 2p - 8 + 4
Now that all the terms are neatly ordered we can simply add the coefficients of the terms with the same variable:

Second graph f(x) = (x - 3) ( x + 1 )
Third graph f(x) = -2(x - 1) (x + 3 )
Step-by-step explanation:
Type functions into Desmos graphing calculator and it will plot the points for you.

The required quadratic function shown in the graph is
f(x)=0.5(x+2)(x-6).
Let us suppose the quadratic function
[tex]f(x)=a(x-\alpha )(x-\beta )[/tex]......(1)
where α and β are roots of the quadratic equation f(x)=0
What is a quadratic equation?Any equation of the form [tex]ax^{2} +bx+c=0[/tex] is called a quadratic equation where a≠0
From the shown graph we can see the roots of f(x)=0 as:
[tex]\alpha =-2[/tex]
[tex]\beta =6[/tex]
So, (1) becomes [tex]f(x)=a(x+2 )(x-6 )[/tex].....(2)
Since the graph is intersecting the y-axis at (0, -6)
So, (0, -6) will satisfy the (2)
So put x=0 and f(x)= -6 in (2)
[tex]-6=a(0-2)(0-6)[/tex]
[tex]a=\frac{-1}{2}=0.5[/tex]
So, [tex]f(x)=0.5(x+2 )(x-6 )[/tex]
Thus, the required quadratic function shown in the graph is
f(x)=0.5(x+2)(x-6).

The large stones of Stonehenge are arranged in a circle about 30 meters in diameter. What
is the radius?
Answer:
The radius is just the diameter split in half, so r = 15 meters.
Explanation:

30/2 = 15
r = 15
Ancient slingshots were made form straps of leather that cradled a rock until it was released. One would spin the slingshot
in a circle, and the initial path of the released rock would be a straight line tangent to the circle at the point of release.
The rock will travel the greatest distance if it is release when the angle between the normal to the path and the horizontal
is -450. The center of the circular path is the origin and the radius of the circle measure 1.25 feet.
Write and equation of the initial path of the rock in standard form.
Answer:
Step-by-step explanation:∠ MON= -45°→→ angle lies in fourth quadrant.
Where, MN represents the path of rock, which is a straight line.
Taking the Horizontal and vertical component of OM,to get the coordinate of point M
The coordinate of point M will be [1.25 cos (-45°), 1.25 sin(-45°)]=
Taking O as center and Coordinates of O as (0,0) and Coordinates of M as () we get the equation of line OM as
y= tan (315°)× x
As general form of equation of line passing through the origin will be,
y= m x, where m is angle made by line with positive direction of x axis.
m= (360-45)°= 315°
→→y=-x
→→ y + x=0
equation of line perpendicular to OM will be
→→ x - y + k=0
Since it passes through .
→→
So, equation of initial path of stone will be:
(3x^2+7)+(2x^2-5x+10)
Answer:
5x² - 5x + 17
Step-by-step explanation:
(3x² + 7) + (2x² - 5x + 10)
Combine the like terms.
3x² + 2x² = 5x²
-5x does not have a like term, so there is no change.
7 + 10 = 17
Combine them, and the final equation is
5x² - 5x + 17.
Answer: 5x² - 5x + 17
Step-by-step explanation:
(3x^2+7)+(2x^2-5x+10)
3x^2 + 2x^2

1. y=-2(x+2)
2. y=2x+8
3. y=5x+1
4. y=4x-7
Answer:
1. y = 2(x + 2)
Step-by-step explanation:
if we substitute the values,
we get 6 = 2*1 + 4
6 = 6
therefore, it is correct.
The system of equations has no solution. hence option d is correct.
What is Equation?Equation is described as the state of being equal, and it is commonly represented as a math expression with equal values on both sides, or it refers to a problem involving numerous variables.
