Answer:
10x - 12y = 192
Step-by-step explanation:
Given the equation :
-5/8x + 3/4y = 12 - - - (1)
8x + 12y = 11 ___(2)
The equivalent form of the first equation which can eliminate the y term :
Multiply (1) by - 16 :
-5/8x * - 16 + 3/4y * - 16 = 12 * - 16
10x - 12y = 192
Hence, Adding the obtained equation and equation(2) will eliminate.

In a random sample of 200 customers at a restaurant, 140 customers ordered french fries. If the restaurant typically has 1,000 customers in a day, about how many will probably order french fries?
Answer: 700 customers
Step-by-step explanation:
In a random sample of 200, 140 people ordered French fries.
Find out the percentage of people who ordered French fries:
= 140 / 200
= 70%
If the restaurant usually has 1,000 customers a day, based on the rate of people who ordered French fries out of 200 people - 70% - the number of people who will probably order French fries are:
= 70% * 1,000
= 700 customers

Step-by-step explanation:
What is the function where it has a maximum point at (pi, 6) and a minimum point at (-3pi/4, 2). Find the function. Give an exact expression.
Answer:
f(x) = 2*cos(4*x) + 4
Step-by-step explanation:
This is obviusly a sinusoidal function, which can be written as:
f(x) = A*cos( w*x ) + M
Where:
A = amplitude
w = angular frequency
M = midline.
Remember that the maximum of a cosine
cos(x) = 1, when x = (2*n)*pi (for any integer n)
And the minimum is at:
cos(x) = -1, when x = (2*m + 1)*pi (for any integer m)
Whit this in mind, we know that we have a maximum when:
x = pi
then we want:
w*pi = (2*n)*pi
and a minimum at:
x = -3*pi/4
Then we want
w*(-3*pi/4) = (2*m + 1)*pi
In the minimum case, we have a "4" in the denominator that is kinda unfortunate, so we woud want to take w = 4 in order to remove it, and this will work really well for wath we want, because:
w*pi = 4*pi = (2*2)*pi (here we have n = 2)
w*(-3*pi/4) = 4*(-3*pi/4) = -3*pi = (2*-2 + 1)*pi (here we have m = -2)
Then we can take w = 4.
So the function is something like:
f(x) = A*cos(4*x) + M
The amplitude is equal to half of the difference between the maximum and the minimum values of y.
The maximum is:
y = 6
the minimum is:
y = 2
Half of the difference is:
A = (6 - 2)/2 = 2
A = 2
Then our function is:
f(x) = 2*cos(4*x) + M
The value of the midline is equal to the maximum minus the value of the amplitude (or the minimum plus the value of the amplitude)
M = Maximum - A = 6 - 2 = 4
M = Minimum + A = 2 + 2 = 4
Then the function is:
f(x) = 2*cos(4*x) + 4

2cos (4/7x - 4pi/7) + 4
Step-by-step explanation:
Write a cubic function whose graph goes through the points: (-5, 0) (1, 0) (2, -2) (4, 0)
Answer:
Step-by-step explanation:
From points (-5,0),(1,0),(4,0) we know it has the form
y=(x+5)(x-1)(x-4)
y=(x^2+4x-5)(x-4)
y=x^3-4x^2+4x^2-16x-5x+20
y=x^3-21x+20
Then it must pass through the point (2,-2) so
-2=[2^3-21(2)+20]b
-2=[8-42+20]b
-2=[-14]b
b=1/7 so the equation is
y=(x^3-21x+20)/7
Which set of measurements determines more than one triangle?
Answer:80,65,20
Step-by-step explanation:
In general, a unique triangle may always be drawn if three side lengths are given and the sum of any two is greater than the third. c) More than one triangle can be drawn with Angle A = 40°, Angle B = 60° and Angle C = 80°. The angles sum to 180°, so at least one triangle may be drawn.

What is unitary method?Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit
What is the current marked value of US dollar to Canadian dollar?1 United States Dollar = 1.28 Canadian Dollar
According to the question
Chevy Volt costs in the United States = $29,600
As, per current marked value
1 United States Dollar = 1.28 Canadian Dollar
Cost in Canada = 29,600 * 1.28 Canadian Dollar
= 37,888 Canadian Dollar
Hence, the Chevy Volt costs in Canada is 37,888 Canadian Dollar

Find the value of x in the trapezoid below.
124°
Answer:
56 degrees
Step-by-step explanation:
just cause
Answer:
56 degrees
Step-by-step explanation:
the total degrees in a quadrilateral is 360
and in a trapezoid the top two angles measure the same and the bottom two measure the same
so since one of the top angles is 124 the one beside it is too
add 124 and 124 you get 248
then subtract it from 360 and you get 112
divide 112 by 2 and you get 56 which is the angle of x

Answer:
105
Step-by-step explanation:
To find the surface area, we need to find the area of all the sides. There are five sides, but four of them are exactly the same.
To find the area of a triangle, you need to do width x height / 2. The width is five and the height is eight. 5 x 8 / 2 = 20. There are three more sides that have the exact same area as this. Since there are four sides that have a surface area of twenty, we do 20 x 4 = 80. Then, we find the area of the bottom piece. To find the area of a square, you need to do length x width. 5 x 5 = 25. Then, we add our two areas to get the final result. 80 + 25 = 105. Therefore, 105 is the surface area of the pyramid.

Answer:
x = ± 2√2
Step-by-step explanation:
Assuming "x2" is x^2 or "x squared", the answer can be derived from "square-rooting" both sides.
√ x^2 = √ 8
Then we simplify.
x = ± 2√2
