Answer:
u = 51
Step-by-step explanation:
(51 + 62) + 14 = u + (62 + 14)
(113) + 14 = u + (76)
127 = u + 76
=> Subtract 76 from each side of "="
51 = u

A student purchased a used car for $5,000. Three months later, the student discovers the car needs major repairs which will cost $2,000. The student must decide whether to repair the car or purchase another car. Which statement is correct?
Answer:
The relevants cost are $2,000
Step-by-step explanation:
Based on the information given in a situation where the student have to decide whether to repair the car or purchase another car the correct statement is: THE RELEVANTS COST ARE $2,000 because the cost of repairs of the Amount of $2,000 represent the RELEVANT COST.
Therefore RELEVANT COSTS are costs or expense that can be incurred due to some certain decisions and on the other hand RELEVANT COSTS which is also known as AVOIDABLE COST can be seen as the cost or expense a person or an individual can do away with depending on other alternative such person choose to pick.

Quadratic below
2^2−7−4
Vertex -
Y-Intercept -
X-Intercept -
Answer:
The y-intercept is y = -4.
The x-intercepts are [tex]x = 4[/tex] and [tex]x = -\frac{1}{2}[/tex]
The vertex is [tex](\frac{7}{4},-\frac{81}{8})[/tex]
Step-by-step explanation:
Quadratic equation:
Has the following format:
[tex]y = ax^2 + bx + c[/tex]
The y-intercept is c.
Finding the x-intercepts:
Given a second order polynomial expressed by the following equation:
[tex]ax^{2} + bx + c, a\neq0[/tex].
This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:
[tex]x_{1} = \frac{-b + \sqrt{\Delta}}{2*a}[/tex]
[tex]x_{2} = \frac{-b - \sqrt{\Delta}}{2*a}[/tex]
[tex]\Delta = b^{2} - 4ac[/tex]
Vertex:
Suppose we have a quadratic function in the following format:
[tex]f(x) = ax^{2} + bx + c[/tex]
It's vertex is the point [tex](x_{v}, y_{v})[/tex]
In which
[tex]x_{v} = -\frac{b}{2a}[/tex]
[tex]y_{v} = -\frac{\Delta}{4a}[/tex]
Where
[tex]\Delta = b^2-4ac[/tex]
In this question:
The quadratic equation is [tex]2x^2 - 7x - 4[/tex], which has [tex]a = 2, b = -7, c = -4[/tex]. This means that the y-intercept is y = -4.
x-intercepts:
[tex]\Delta = (-7)^2-4(2)(-4) = 81[/tex]
[tex]x_{1} = \frac{-(-7) + \sqrt{81}}{2*2} = 4[/tex]
[tex]x_{2} = \frac{-(-7) - \sqrt{81}}{2*2} = -\frac{1}{2}[/tex]
The x-intercepts are [tex]x = 4[/tex] and [tex]x = -\frac{1}{2}[/tex]
Vertex:
[tex]x_{v} = -\frac{(-7)}{2*2} = \frac{7}{4}[/tex]
[tex]y_{v} = -\frac{81}{4(2)} = -\frac{81}{8}[/tex]
The vertex is [tex](\frac{7}{4},-\frac{81}{8})[/tex]
What is the slope-intercept equation of the line below? y-intercept=(0,2) slop=-1/4
Answer:
y=-1/4x+2
Step-by-step explanation:
So the forumla for slope/intercept equation is:
y=mx+b
Y equals the y coordinates on the graph. This is the value that you plug in x to solve for.
m equals the slope of the graph. (In this case -1/4)
x equals the x coordinates. This will always be just x when writen in a slope intercept equation, since x is the value you plug in to solve for y.
b equals the y intercept. This is different from the y coordinates. This is a known value, which can be found when x=0. (In this case 2)
Now, using this lets plug in our numbers for the differet variables:
y=mx+b
We know that m, the slope, is -1/4. So:
y=-1/4x+b
We also know that b, the y inteercept, is 2. Since we have the coordiantes (0x, 2y). So:
y=-1/4x+2
This is all you have to do! This is because y is the number you solve for, and x is the value you plug.
Hope this makes sense and helps! :)

What is the period of a cosine function?The period of a cosine function can be defined as the overall length of the interval of values on the x-axis over which a graph lies and it's repeated. Mathematically, the period of this parent cosine function [y=cos(x)] is given by:
T = 2π/A
Where:
A is the coefficient of the x.When A = 1, we have:
T = 2π/1 = 360 degrees.
For the graphed function, the period of this cosine function is given by:

The point-slope equation of a line is
O A. y+ X- XV0 = m
O B. y= m(x-yo)
O C. y+ mx - mxoyo
O D. y-yo = m(x - xo)
Answer:
D. [tex] y - y_0 = m(x - x_0) [/tex].
Step-by-step explanation:
The equation of a line can be written in the point-slope form if we know the the coordinates of a point the line passes through which is [tex] (x_0, y_0) [/tex]. And if we also know the slope = m of the line.
Therefore, the point-slope equation is given as:
[tex] y - y_0 = m(x - x_0) [/tex]

Answer:
93
Step-by-step explanation:
(85 + 92 + 87 + 93 + 90 + x)/6 = 90
(447 + x)/6 = 90
multiply both sides of the equation by 6:
447 + x = 540

In which choice do all three points lie on the
same straight line?
A А.
(0, 1), (-1, 3), (1, 3)
B.
(4, 2), (2, 1), (4, -2)
C (0, 0), (8, 0), (0, 8)
D
(1, 2), (2, 4), (4,8)
Answer:
D (1, 2), (2, 4), (4,8)
Step-by-step explanation:
Points lying on the same line:
If three points lie on the same line, the change in y has to be always the same when x changes by 1.
А. (0, 1), (-1, 3), (1, 3)
(-1,3) to (0,1): x changes by 1, y by -2
(0,1) to (1,3): x changes by 1, y by 2
So these points are not on the same line.
B. (4, 2), (2, 1), (4, -2)
Two values for y when x = 4, so not on the same straight line.
C (0, 0), (8, 0), (0, 8)
Two values for y when x = 0, so not on the same straight line.
D (1, 2), (2, 4), (4,8)
Here, when x changed by 1(from 1 to 2), y changed by 2.
When x changed by 2(from 2 to 4), y changed by 2*2 = 4.
So these points are on a straight line, and D is the correct answer.
Find the volume of the solid
Answer:
552
Step-by-step explanation:
Answer:
V = 552 mm^3
Step-by-step explanation:
To find the volume of a prism, you multiply the base and the height. We can write an equation to model the situation:
V = Bh
Where V is the volume, B is the base, and h is the height.
We can substitute the values we have:
V = 92 x 6
V = 552 mm^3
Lincoln buys milk and oranges at the store.
He pays a total of $41.63.
He pays a total of $4.19 for the milk.
• He buys 6 bags of oranges that each cost the same amount.
.
Write and solve an equation which can be used to determine x, how much each bag
of oranges costs.
Answer:
$6.24
Step-by-step explanation:
equation: $41.63 - 4.19 = 37.44
solve: 37.44 ÷ 6 = 6.24.
hope this helped!
Answer:
He pays a TOTAL of $41.63. Meaning everything is equal to that value
He pays 4.19$ for Milk
He buys 6bags of Oranges and each of these cist the same amount.. let's say x.
So 6 bags would cost 6x
So Total is
6x + 4.19 =41.63
6x= 41.63-4.19
6x=37.44
x=37.44/6
x=$6.24
To check this
6x + 4.19 should equal 41.63$
6(6.24) + 4.19= $41.63

which equation best represents the relationship between x and y in the graph
Answer:
A
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (0, 3) ← 2 points on the line
m = [tex]\frac{3-0}{0+1}[/tex] = [tex]\frac{3}{1}[/tex] = 3
The line crosses the y- axis at (0, 3 ) ⇒ c = 3
y = 3x + 3 ← equation of line → A
