Since the provided equation is inconsistent, it cannot intersect.
What is equation?The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign. A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.
Here,
we can see that the second set of equation,
4x+2y=12
20x+10y=30
4/20=2/10≠12/30
1/5=1/5≠2/5
The given equation is inconsistent so it does not intersect.

Step-by-step explanation:
1. A toy company finds there is a linear relationship between p, the price they charge for a playground ball, and n(p), the number of balls they sell during a year. When they charge $3, they sell 8000 balls during the year. However, sales drop to 5200 balls when they charge $5 each.
a. Write an equation for the linear function n(p).
b. Use your function to determine the number of balls they can expect to sell during the year if they charge $6.50 for a ball.
Answer:
Below in bold.
Step-by-step explanation:
The general form of a linear function can be written as:
n(p) = kp + C where k and C are constants.
So substituting the given data:
8000 = 3k + C
5200 = 5k + C Subtract
2800 = -2k
k = -1400
and C = 8000 - 3(-1400) = 12200
a. So the equations is:
n(p) = -1400p + 12200
b.
For a charge p of $6.50;
n(p) = -1400*6.5 + 12200
= 3100 balls.
What is the remainder when (x4 36) is divided by (x2 – 8)?
Answer:
(x4 36) I didn't that is . or + so I solved it on +
Hope that what you looking for :)
Step-by-step explanation:
BY Using the long divison method, x⁴ + 36 is divided by x² - 8 is 100
Dividend = x⁴ + 36
Divisor = x² - 8
_____x²+8
x² - 8 | x⁴ + 36
| x⁴ - 8x²
-8x² + 36
8x² - 64
_100
The remainder is calculated as (36 - (-64)) = (36 + 64) = 100
Therefore, the remainder is 100
Which statement about 214° is correct?
O A. tan 214° < 0
O B. sin 214° < 0
O C. cos 214° > 0
Answer:
B.
Step-by-step explanation:
214 degree terminates in the 3rd quadrant.
Sine and cosines are both negative there.
This means that sin(214)<0 and cos(214)<0.
If sine and cosine are both negative and since tangent is the quotient of them, then tangent is positive, or tan(214)>0.
A Parabola is graphed below. What is the vertex form of the parabola?
A. y=( x - 3 )² + 5
B. y= -5 ( x - 2 )² - 3
C. y= 3 ( x - 2 )² - 5
D. y= -1 ( x - 3 )² + 5
The graphed quadratic equation, in vertex form, is:
y = 3*(x - 2)^2 - 5
So the correct option is C.
What is the vertex form of the parabola?Remember that for a quadratic equation with a leading coefficient a and a vertex (h, k), the vertex form is:
y = a*(x - h)^2 + k
Here we can see that the vertex is at the point (2, -5), replacing that we will get:
y = a*(x - 2)^2 - 5
We also can see that the parabola passes through (0, 7), then we can replace that to get:
7 = a*(0 - 2)^2 - 5
7 = 4a - 5
7 + 5 = 4a
12/4 = a
3 = a
The quadratic equation is:
y = 3*(x - 2)^2 - 5
The correct option is C.

A gym's membership in 2012 was 9,300. The current membership is 2,800. Which expression can be used to find the percent of change? WHAT EXPRESSION NOT WHAT THE PERCENT IT.
The expression that can be used to find the percent of change between the gym's membership in 2012 and the current membership is ((Current Value - Initial Value) / Initial Value) \(\times\) 100.
To find the percent of change between the gym's membership in 2012 and the current membership, we can use the following expression:
Percent of change = ((Current Value - Initial Value) / Initial Value) \(\times\) 100
In this case, the initial value is 9,300 (membership in 2012), and the current value is 2,800 (current membership).
Substituting these values into the expression, we get:
Percent of change = ((2,800 - 9,300) / 9,300) \(\times\)100
Simplifying the expression further, we have:
Percent of change = (-6,500 / 9,300) \(\times\) 100
Therefore, the expression that can be used to find the percent of change between the gym's membership in 2012 and the current membership is ((Current Value - Initial Value) / Initial Value) \(\times\)100. This formula calculates the relative difference between the initial and current values and expresses it as a percentage.

The perimeter of rectangle is 208 ft.
What is perimeter of rectangle?The perimeter of a rectangle is the total length or distance of its boundary on all sides. The perimeter of a rectangle is a linear measure and is expressed in linear units of meters, feet, inches, or yards. Let us first understand the two main properties of a rectangle.
All four angles of a rectangle are 90°.The opposite sides of a rectangle are equal in measure.Therefore, the Perimeter of a rectangle = 2(l + w).
Given:
length = 47 ft
width = 57 ft
So, the perimeter of rectangle
= 2( l + w)
=2( 47 + 57)
= 2 x 104
= 208.

30 POINTS!!, SHOW WORK The figure is a rhombus. Find the value of x.
a) x = 13
b) x = 12
c) x = 169
d) x = 119
Answer:
x = 13
Step-by-step explanation:
The diagonals of rhombi are perpendicular and form a right angle at their intersection. Furthermore, they bisect each other and create four congruent segment. Thus, the measures of the other two sides of the triangle shared by x is 5 and 12.
Thus, x is the hypotenuse of the triangle and is opposite the right angle.
Since we have a right triangle, we can find x using the Pythagorean theorem, which is
a^2 + b^2 = c^2, where
a and b are the shorter sides called legs,and c is the longest side of the hypotenuse.We plug in 5 and 12 for a and b, allowing us to solve for c (aka x):
5^2 + 12^2 = c^2
25 + 144 = c^2
169 = c^2
13 = c
Thus, x = 13 units

Find the value of w and YZ if Y is between X and Z.
XY = 4w YZ = 6W XZ = 12w - 8
Answer:
w = 4
YZ = 24
Step-by-step explanation:
Since, Y is a point lying between the points X and Z.
Therefore, relationship between the lengths of the segments will be,
length of segment XZ = length of XY + length of YZ
It's given in the question,
XZ = 12w - 8
YZ = 6w
XY = 4w
By substituting these values in the relation,
12w - 8 = 4w + 6w
12w - 8 = 10w
12w = 10w + 8
12w - 10w = 8
2w = 8
w = 4
Since, YZ = 6w
Therefore, YZ = 24

The depth of the water in a tank after t minutes is modeled by f(t) = 5+1.5t, measured in inches. Find and interpret (10).
A) 20; The depth of the water after 10 minutes is 20 inches.
B) 20; The water reaches a depth of 10 inches after 20 minutes.
C) 65; The depth of the water after 10 minutes is 65 inches.
D) 65; The water reaches a depth of 10 inches after 65 minutes.
The depth of water after 10 minutes is 20 inches which is the option A.
Given that:-
Depth of water in a tank after t minutes is modeled by the function f(t) = 5+1.5t, measured in inches.
Let us check for Option A.
Putting t = 10 min in the given equation, we get,
f(10) = 5 + 1.5*10 = 5 + 15 = 20 inches.
Hence, option A is the right answer.
We can also check the other options to confirm our answer.
Putting t = 20 minutes,
f(20) = 5 + 1.5*20 = 5 + 30 = 35 inches
As 10 inches is written in B, hence, it is not the right answer.
We already know that t = 10 gives 20 inches.
Hence, C is not the answer.
Putting t = 65 minutes,
f(20) = 5 + 1.5*65 = 5 + 97.5 = 102.5 inches
As 10 inches is written in D, hence, it is not the right answer.
