-7x - 2y = 14
6x + 6y = 18
Answer:
x=-4, y=7
Step-by-step explanation:
Answers : x = (15/6), y =
(1/2).
Step-by-step explanation:
Explanation: To solve this equation through elimination, you need to isolate one of the variable. You can isolate the y variable since the x variables can be subtracted and go away. Add the two equations to get rid of one variable. (6x + 6y = 18) + (-6 + 2y = -14) = (8y = 4). Now you need to solve for y. y = 4/8, y = 1/2. Now, plug the y back into one equation and solve for x. 6x + 6(1/2) = 18. 6x + 3 = 18. 6x = 15. x = 15/6. Plug the two answers back in to the equation to check your answers. 6(15/6) + 6(1/2) = 18, 15 + 3 = 18. -6(15/6) + 2(1/2) = -14, -15 + 1 = -14.
Which expression is equivalent to 2(x2 – 1) + 3x(x – 4)?
(1) 5x2 – 5
(3) 5x2 – 12x – 1
(2) 5x2 - 6
(4) 5x2 – 12x – 2
The equivalent expression of 2(x² – 1) + 3x(x – 4) is 5x² - 12x - 2
How to find equivalent expression?
The equivalent expression of the expression can be found as follows;
2(x² – 1) + 3x(x – 4)
open the brackets
2x² - 2 + 3x² - 12x
Therefore, let's combine like terms
2x² + 3x² - 12x - 2
Let's do the arithmetic for like terms
2x² + 3x² - 12x - 2
5x² - 12x - 2
Therefore, the equivalent expression of 2(x² – 1) + 3x(x – 4) is 5x² - 12x - 2

Patty made a banner that has an area of 112 square inches. The length and width of the banner are whole numbers. The length is 7 times greater than the width. What are the dimensions of the banner?
Answer:
The width of the banner is 4 inch and the length of the banner is 28 inch
Step-by-step explanation:
Given
Length is seven times its width
Let the width be "X", then length would be 7X
The banner is of rectangular shape.
Its area is 112 square inches
[tex]X* 7X = 112\\7X^2 = 112\\X^2 = 16\\X = 4[/tex]
Hence, the width of the banner is 4 inch and the length of the banner is 4*7 i.2 28 inch

In spherical geometry, some quadrilaterals are parallelograms is a true statement. Thus option D is correct.
What is spherical geometry?Instead of the sort of geometries studied in trigonometry or solid geometry, the research of shapes on a structure's surface. White lines are large rounds in spherical, therefore any three layers intersect at two locations.
A spherical quadrilateral is a bounded surface that is homomorphic to a compact disk. It has four distinct local maxima called extremities, a Riemannian measurement that has constant curvature 1 everywhere else, aside from the corners, and or the demarcation arcs between it intersections. a dome shape. the collection of rectangular shapes with specified angles.

A ball falls vertically after being dropped.
The ball falls a distance dmetres in a time of t seconds.
dis directly proportional to the square of t.
The ball fals 20 metres in a time of 2 seconds.
(a) Find a formula for din terms of t.
Answer:
d = 5t^2
Step-by-step explanation:
"d is directly proportional to the square of t"
d = kt^2
To find k use
"The ball falls 20 metres in a time of 2 seconds."
20 = k(2^2)
20 = k(4)
Divide both sides by 4
5 = k
Using k = 5 the formula becomes
d = 5t^2
Mia took 20 seconds to run 100m. Find the ratio of distance traveled to the time Emma took to run 100m.
Answer:
The ratio should be 100 : 20. If it needs to be simplified then 5:1
Step-by-step explanation:
100 m is the distance traveled and the time it took was 20 seconds. Divide both sides by 20 and you get 5:1
(If it doesn't need to be simplified then 100 : 20)

Answer:
here, suppose the missing length be X
hy ^2 = (one side square )^2 +(Other side square)^2
29^2= X^2 + 21^2
841 = X^2 + 441
X^2 = 841 - 441
X^2 = 400
X = 20 .........taking square root both side
the value is missing side length is 20 .

27
29

14
12
Using this distribution, find the probability that a
person will retake their selfie exactly 1 time.
p = [?]
Answer:
The probability is 0.29
Step-by-step explanation:
Firstly, we need to know the total number of retakes
That is simply the sum of the frequencies
we have this as;
27 + 29 + 18 + 14 + 12 = 100
so the probability of retaking exactly once will be the number of 1 retakes divided by total
That would be 29/100 = 0.29
