What Is The Solution To This System Of EquationsA. (4,2)B. (8,4)C. (4,8)D. (2,4)

Answers

Answer 1

Answer:

B. (8,4)

Step-by-step explanation:

To find the solution of the system, look at where the lines intersect. The intersecting point is (8,4). The solution to the system of equations is (8,4).

Answer 2

Answer:

B. (8,4)

Step-by-step explanation:

We want to find when these two equations are equal. The long way is to actually solve them using elimination or substitution of the equations. But, we can see an easier and clever way to solve them.

There is one specific time when equations are equal and that is when their lines intersect or cross, notice the graph and where they intersect. That specific coordinate where they intersect is your answer, (8, 4)!

a =
= [? ]cm

Answers

Answer:

a = 1.8 cm

Step-by-step explanation:

Here. we want to find the value of a

To do this, we are going to use the sine rule

it states that the ratio of a side and the sine of the angle that faces the side is a constant for all the sides of a triangle

From the diagram, we have that;

The angle facing a is;

180-15-105 = 60

So, we have that

a/sin 60 = 2/sin 105

a = 2sin 60/sin 105

a = 1.794 cm

What are the solution(s) of x squared minus 4 = 0

Answers

Answer:

x=2 or x= -2

Step-by-step explanation:

x^2 - 4 = 0

x ^2  − 4  +  4  =  0 + 4  

x^2 = 4

√ ( x ^2 ) = √ 4

=  ±  2  =  { x 1 = − 2

              x 2 = 2

Answer:

X=2 or X=-2

Step-by-step explanation:

x^2 - 4 = 0

x ^2  − 4  +  4  =  0 + 4  

x^2 = 4

√ ( x ^2 ) = √ 4

=  ±  2  =  { x 1 = − 2

Answers

Answer:

a. 16

Step-by-step explanation:

Consider these 3 values.

[tex] \sqrt{16} \\ \sqrt{27} \\ \sqrt{35} [/tex]

Factor 16,27 and 35.

[tex] \sqrt{4 \times 4} \\ \sqrt{3 \times 3 \times 3} \\ \sqrt{3 \times 3 \times 5} [/tex]

Pull out two same numbers out of the root.

[tex]4 \\ 3 \sqrt{3} \\ 3 \sqrt{5} [/tex]

Rational only when there are no square roots after simplify/evaluating.

Thus a. 16 is only rational here.

I believe it would 16 because it’s the only number that has a whole number as it’s square root(4) the other numbers have decimals

Substitute x = 2y - 2 into the expression 5x

Identify the x- and y-intercepts of the equation
4x - y = 8

Answers

Answer:

[tex]\boxed{\boxed{\pink{\sf \leadsto The \ x - intercept \ is \ (2,0) \ \& \ the \ y \ intercept \ is \ (-8,0) }}}[/tex]

Step-by-step explanation:

A linear equation is given to us and we are required to find x and y Intercepts to it. So the given linear equation to us is ,

[tex]\bf \implies 4x - y = 8 \\\\\bf\implies \dfrac{1}{8} \bigg( 4x -y\bigg) =\frac{1}{8}\times 8 \\\\\bf\implies \dfrac{4x}{8}-\dfrac{y}{8} = \dfrac{8}{8} \\\\\bf\implies \dfrac{x}{2}-\dfrac{y}{8}=1 \\\\\bf\implies\boxed{\red{\bf \dfrac{x}{2}+\dfrac{y}{-8}=1 }}[/tex]

Hence on comparing to standard form we get

x intercept as (2 , 0 )y intercept as (0,-8)

Hence the x - intercept is ( 2 , 0 ) and the y - intercept is ( 0 , -8 ) .

Answer:

x = (2,0)

y = (0,-8)

Step-by-step explanation:

Remember than an intercept always has the other number as 0.

Let's put this in standard form of a linear equation, or y = mx + b

4x - y = 8

-y = -4x + 8

y = 4x - 8

"b" is the y intercept. The y intercept is -8, or (0,-8)

Now, to find the x intercept, all we have to do is substitute 0 for y.

0 = 4x -8

8 = 4x

2 = x

The x intercept is 2, or (2,0)

How many presents would shelia wrap in 6 hours if she wrapped 4 presents every 4 minutes?

Answers

Answer:96

Step-by-step explanation:

Well 4 presents every 4 minutes is the same thing as 1 present every 1 minute.
So now, we know that every 1 minute, she wraps 1 present.
Now, in 6 hours, there are 360 minutes so, we would simply multiply 1 present by 360 minutes which gives us the answer of 360 presents wrapped in 6 hours.
