What is the solution to the following system of equations?

Answers

Answer 1

Answer:

Answer:

The correct answer is first option (-5, 5)

Step-by-step explanation:

It is given that,

3x - 4y = -35 and 3x + 4y = 5

To find the solution

Let, 3x - 4y = -35 ------- (1)

3x + 4y = 5 --------(2)

Eq(1) + (2) ⇒

6x = -35 + 5 = -30

x = -30/6 = -5

ex(1) ⇒ 3x - 4y = -35

3 *-5 - 4y = -35

-15 - 4y = -35

4y = -15 + 35 = 20

y = 20/4 = 5

Therefore x = -5 and y = 5

The correct answer is first option (-5, 5)

Answer:

See explanation

Step-by-step explanation:

Points A(-3, -3), B(-2, 2), C(3, 3), and D(2, -2) are the vertices of a quadrilateral.

Find lengths of the sides as distances between points:

$AB=√((-2-(-3))^2+(2-(-3))^2)=√(1^2+5^2)=√(26)\ units\n \nBC=√((3-(-2))^2+(3-2)^2)=√(5^2+1^2)=√(26)\ units\n \nCD=√((2-3)^2+(-2-3)^2)=√(1^2+5^2)=√(26)\ units\n \nAD=√((2-(-3))^2+(-2-(-3))^2)=√(5^2+1^2)=√(26)\ units$

Since all lengths of sides are the same, quadrilateral ABCD is the rhombus.

What is the range of possible sizes for side x? _ < x < _

Answers

Answer:

0.5 < x < 16.5

Step-by-step explanation:

The third side of the triangle must be longer than the difference of the other two sides:

x > (8.5 -8.0)

x > 0.5

And it must be shorter than their sum:

x < (8.5 +8.0)

x < 16.5

The third side must be in the range ...

0.5 < x < 16.5

_____

These limits are a direct consequence of the triangle inequality, which requires the sum of the two shortest sides exceed the length of the longest side.

Step-by-step explanation:

33 is 33% of what number?

Answers

here's a hack
1% means 1/100

if 33=33/100 and you want to find 100/100 then since the numbers correspond, you just assume that 100% is 100

33 is 33% of 100.
When you see that a number is the same as the percentage that is given. That usually means that it is out of 100. Therefore taking 33% out of 100 is simply 33.
