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
x 2 = 2

What does this equals??
Answers
Answer:
7x + 2
Step-by-step explanation:
Original Equation: 3x − ( −2 − 4x)
First, we distribute the negative sign:
= 3x + (−1) (−2−4x)
=3x + (−1)(−2) + (−1)(−4x)
= 3x + 2 + 4x
Using the communitive property of addition, we can write:
= 3x + 4x + 2 (Instead of 3x + 2 + 4x)
Combining like terms, we get:
= (3x + 4x) + 2
= 7x + 2

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

Answer:96
Step-by-step explanation:
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.

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