Answer:

x=8, y=-1

Step-by-step explanation:

The figure is said to be a rectangle, which means opposite sides have to be equal in length. From this, we can write a system of equations:

5x-2y=42

2x+3y=13

There are a number of ways to solve this but I'll go with elimination--that means you need to try to remove one variable first by manipulating the equations and solve for the other variable. Then you use the solution to solve for the variable you initially removed. That sounds confusing, but let me show you how to do it.

If you multiply the first equation by 3 and the second equation by 2, you'll have have:

15x-6y=126

4x+6y=26

Now, we can add these two equations. The y will cancel out, so we can easily solve for x.

19x=152

x=8

Use this value of x to substitute back into either of the original equations to find y.

5(8)-2y=42

40-2y=42

-2y=2

y=-1

14.62 rounded to the nearest number
ArbitrLikvidat [17]

Answer:

15

Step-by-step explanation:

To answer this, we would have to look at the last place first, which is the hundredths place. In the hundredths place, we have a 2. 2 is less than 5, so we would just pretend it isn't there since we would round down. Now, looking at the tenths place, which is the 6, we can determine whether or not we round. If the number is 5 and above, (including 5) we would round up. In this case, it is 6, so we would round the number in front of it (4) up by one to get 15.

Brainliest would be appreciated!

The volume of a cone is 50 pi cubic feet. Its height is 6 feet. In feet, what is the radius of the cone? Round the answer to the
defon

Answer:

Radius= 5.0ft ( given)

Step-by-step explanation:

Given: Volume of cone= 50π ft^3

Height of cone= 6ft

Required: Radius

Volume of cone= 1/3 * π * r^2 *h

(or)

r^2= Volume *3/h π ( Just disintegrating the formula and taking radius^2 to the left hand side(L.H.S) )

= (50 π *3)/(6)π

= 50/2 (because, 3 π /6 π = 1/2)

r^2 = 25

now, r =√25= 5.0 ft

Therefore, the radius of the cone is 5.0 ft(to the nearest tenth) :)

Which graph represents an odd function?
Nookie1986 [14]

Answer:

<h2>The first graph in the second image is an odd function.</h2>

Step-by-step explanation:

An odd function has a graph that it's symmetric about the origin, that is, the origin is like a mirror. In other words, the graph of an odd function has a specific symmetry about the origin.

So, we have to look for those graph that has symmetrical points in opposite quadrants, I and III or II and IV.

You can observe that the first graph of the second image has this behaviour. You can see that the points are symmetrical across the origin. If you graph a line defined as y=-x, you will observe that such line acts like a mirror.

Therefore, the odd function is the first graph in the second image.

Find the area of triangle ABC. Give your answer to 1 decimal place. Sine rule.
laiz [17]

Answer:

<h2> 31.7 cm^2</h2>

Solution,

In ∆ ABC

< A + <B + < C = 180°

or, 72 + 59 + <C = 180°

or, 131 + <C = 180°

or, <C = 180 - 131

< C = 49

Area of ∆ABC = 1/2 ab sin C

= 1/2 * 12 * 7 * sin 49

= 42 * sin 49

= 31.7 ( approximately)

Hope this helps...

Good luck on your assignment...
