4x + 8y = 20 and -4x + 2y = -30

Mathematics
1 answer:
Ainat [17]3 years ago
4 0

Step-by-step explanation:

<u>Given </u><u>:</u><u>-</u><u> </u>

  • 4x + 8y = 20
  • -4x + 2y = -30

<u>Adding</u><u> the</u><u> equations</u><u> </u><u>:</u><u>-</u><u> </u>

: \implies 10y = -10

: \implies y = -1

<u>Put </u><u>it </u><u>(</u><u>i)</u><u> </u><u>:</u><u>-</u><u> </u>

: \implies 4x - 8 = 20

: \implies 4x = 20 + 8

: \implies 4x = 28

: \implies x = 28/4

: \implies x = 7

Explain to me in words how you would find the slope of this line and explain answer
Andrews [41]
Answer:
7/3

Explanation:
The slope of the line is equal to the rise/run, or in other words, the number of units the line travels upwards over the number of units the line travels to the right.

We can identify the slope using any two points on the line. Here, we can use the two points that are marked on the picture. The second point is 7 units above the first and 3 units to the right of the first, so the slope of the line is equal to 7/3.

Another way to calculate the slope of the line is the use this formula:

(y2-y1)/(x2-x1)

The first point is at the coordinate (1,-4) and second point is at the coordinate (4,3). When we plug these two coordinates into the equation, we get this:

(y2-y1)/(x2-x1)
->(3-(-4))/(4-1)

When we simply the fraction, we would get 7/3 and that would give us the slope.

I hope this helps!

What is the area of triangle ABC? Round to the nearest hundredth of a square unit. 17. 75 square units 81. 33 square units 372.
jolli1 [7]

The area of the triangle ABC is 81. 33 square units.

We have to determine

What is the area of triangle ABC?

<h3>What is the formula for the area of a triangle?</h3>

The area of the triangle is determined by;

\rm Area \ of \ triangle = s\sqrt{s(s-a)(s-b)(s-c)}

Where the value of s is = a + b + c= 12 + 14 + 16 = 42

Substitute all the values in the formula;

\rm Area \ of \ triangle = \sqrt{s(s-a)(s-b)(s-c)}\\\\\rm Area \ of \ triangle = \sqrt{21(21-12)(21-14)(21-16)}\\\\\rm Area \ of \ triangle = \sqrt{(21 \times 9 \times 7 \times 5)}\\\\Area \ of \ triangle =\sqrt{6,615}\\\\Area \ of \ triangle = 81.33

Hence, the area of the triangle ABC is 81. 33 square units.

Determine whether the following equation defines y as a function of x.
Aleks04 [339]

Answer:

The equation can define y as a function of x and it also can define x as a function of y.

Step-by-step explanation:

A relation is a function if and only if each value in the domain is mapped into only one value in the range.

So, if we have:

f(x₀) = A

and, for the same input x₀:

f(x₀) = B

Then this is not a function, because it is mapping the element x₀ into two different outputs.

Now we want to see it:

x + y = 27

defines y as a function of x.

if we isolate y, we get:

y = f(x) = 27 - x

Now, this is a linear equation, so for each value of x we will find an unique correspondent value of y, so yes, this is a function.

Now we also want to check if:

x +  y = 27

defines x as a function of y.

So now we need to isolate x to get:

x = f(y) = 27 - y

Again, this is a linear equation, there are no values of y such that f(y) has two different values. Then this is a function.
