What is the value of x in the solution to the system of equations below?
15x - 12y = 13
30x + 9y = 4
Answer:
1/3
Step-by-step explanation:
Use the elimination method.
15x - 12y = 13
30x + 9y = 4
If you add both equations you will not cancel out any variables, so you need to multiply one of the equations by something. Multiply the first equation by -2 to cancel out the x values.
-2(15x - 12y = 13)
30x + 9y = 4
You should have these two equations now:
-30x + 24y = -26
30x + 9y = 4
Add them together now. You should get this now.
33y = -22
Divide both sides by 33. You should get y = -2/3
Now, substitute the y value into any of the two equations that you started with. Let's substitute the y value for the second equation.
30x + 9 (-2/3) = 4
30x - 6 = 4
30x = 10
30 30 (divide 30 and 10 by 30)
x = 1/3
 How do I know whether this is a function or not? And can someone EXPLAIN the steps on how to determine on how it would be a function please?
Answer:
Yes
Step-by-step explanation:
A function would be f(x), a output for each x input.
The slope intercept form is y - mx + b! *keep this in mind*
If you graph this as well, it would be easier to see if its a function too. If the line crosses through it once, it is indeed a function. If it doesn't, it isn't

Explanation:
This is a 45-45-90 right triangle. Any triangle of this form is isosceles, where the two legs are the same length. In this case, m and n are those two legs. So m = n.
We can then apply the Pythagorean theorem to say
a^2 + b^2 = c^2
m^2 + n^2 = (9*sqrt(2))^2
m^2 + m^2 = 9^2*(sqrt(2))^2
2m^2 = 81*2
m^2 = (81*2)/2
m^2 = 81
m = sqrt(81)
m = 9
As a shortcut, the hypotenuse of a 45-45-90 triangle is equal to sqrt(2) times the length of either leg. If m is the length of the leg, then m*sqrt(2) is the length of the hypotenuse. So in a sense, we take this thought process backwards to go from a hypotenuse 9*sqrt(2) to a leg length of 9.

Which expression is equal to (7 * 2) 2?
A)(7 + 2) × 2
B)(2x2)+7
C)7x(2 x 2)
D)(2 x 7) + (2x2)
Answer:
C. 7 * (2 * 2)
Step-by-step explanation:
Figure out the original expression to see the equivalent expression.
(7 * 2) * 2
14 * 2
28
We have to look for an expression that equals 28.
A is (7 + 2) * 2.
(7 + 2) * 2
9 * 2
18
A equals 18, so it's not equivalent to the original expression.
Now B, which is (2 * 2) + 7
(2 * 2) + 7
4 + 7
11
B equals 11, so it is also not equivalent.
Now C; that is 7 * (2 * 2)
7 * 4
28
C equals 28, so that is equivalent. Although we have found our answer, we need to make sure it's right by evaluating D. ((2 * 7) + (2 * 2))
(2 * 7) + (2 * 2)
14 + 4
18
D, like A, equals 18, so it is also incorrect.
C is the only expression that is equivalent to (7 * 2) * 2, so it is the answer.
Write an equation in slope-intercept form for the graph shown.
Answer:
y = -3x + 2
Step-by-step explanation:
b is your y intercept, where the line crosses the y axis
m is your slope, since the line is going down we know it is negative
the slope was -6/2, which simplifies to -3

Rectangle ABCD has a width of 8 yards and a length of 20 yards. Rectangle QRST, which is similar to rectangle ABCD, has a length of 40 yards.
Find the scale factor of ABCD to QRST and the perimeter of each rectangle.
Answer: 16 yards would be your answer
The scale factor of ABCD to QRST is 1:2
The perimeter of rectangles ABCD and QRST are 56 yards and 112 yards respectively.
Rectangle ABCD has a width of 8 yards and a length of 20 yards.
Rectangle QRST is similar to rectangle ABCD.
Rectangle QRST has a length of 40 yards.
Scale factor:Therefore, the scale factor of ABCD to QRST can be calculated as follows:
let
x = width of rectangle QRST
8 / x = 20 / 40
8 / x = 1 / 2
x = 16
The scale factor of ABCD to QRST is 1:2
Perimetersperimeter ABCD = 2(8 + 20) = 56 yards
perimeter QRST = 2(16 + 40) = 112 yards.
