Answer:
(1, -9)
Step-by-step explanation:
4x + y = -5
8x + 3y = -19
If we have to use elimination, that means we're going to add or subtract these two whole equations by each other so that we can cancel out one of the variables.
I think that we could easily turn 4x into 8x if we multiply the top equation by 2.
4x + y = -5 ---> 8x + 2y = -10
Now put them next to each other, and subtract to get rid of the xs.
8x + 2y = -10
- 8x + 3y = -19
------------------------
0x - y = -10 - -19
-y = 9
y = -9
Plug this back in to get x.
4x + y = -5
4x - 9 = -5
4x = -5 - -9
4x = 4
x = 1
Answer:
c = 9.43 cm
Step-by-step explanation:
Here, we want to get the measure of the missing side
By the use of Pythagoras’ theorem, the square of the hypotenuse equals the sum of the squares of the two other sides
we have this as follows;
The side c represents the hypotenuse as it faces the hypotenuse
We have this as;
c^2 = 5^2 + 8^2
c^2 = 25 + 64
c^2 = 89
c = √89
c = 9.43 cm
Well... hell, let's just convert them all with the same denominator then
hmmm let's see, we have the denominators of 8,11 and 3
so... we'll multiply the 5/8 times (11*3) or 33
and then we'll multiply 7/11 times (8*3) or 24
and then we'll multiply 2/3 times (8 * 11)
notice, we're simply using the other's denominator's product, to multiply the fractions... anyhow... let's check
Given that the integral is given as
, Hence, we are required to find the area under the graph where t is between 0 and 12. The correct answer is 2 (Option A) See the explanation below.
<h3>What is an integral?</h3>
An integral is a function of which a given function is the derivative, that is, when differentiated, it returns that function, and it can express the area under the curve of a graph of the function.
Hence the areas under the graph for the above function are given as:
12 + 6 + 2 + (-2) + (-16)
= 20-18
= 2
Notice that the following figures were arrived at by dividing the areas under the graph into common geometric shapes and deriving their area.
For example, the first three positive values were derived by dividing the positive part of the graph into two triangles and a rectangle.
The length of the rectangle is 6 while its height is 2
Area of a rectangle is L x W
= 6 * 2
= 12
It is to be noted that the areas under the curve are negative hence the negative results. See the attached image.

Yes It is but its hard to break down but it certainly is
