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

Suppose y varies directly as x, and y=26 when x=8. Find x when y=65.
Answer:
when y=65, x=20
Step-by-step explanation:
We are given:
y varies directly as x
and y=26, when x=8
We need to find x, when y = 65
y varies directly as x can be written as:
[tex]y\:\alpha \:x\\y=kx[/tex]
Where k is constant of proportionality.
Finding k, when y=26 and x=8
[tex]y=kx\\26=k(8)\\k=\frac{26}{8}\\k=3.25[/tex]
We get the value of k = 3.25
Now, we need to find value of x, when y=65 and k=3.25
[tex]y=kx\\65=3.25(x)\\x=\frac{65}{3.25}\\x=20[/tex]
So, when y=65, x=20
Solve for x
CAN SOMEONE PLEAAAAAAAAAAAAAAAAAAAAAAAASE HELP ME
Answer:
x= 12
Step-by-step explanation:
First, we can note that the angles in a pentagon add up to 540°
We can, using the image below, conclude that angles a+b+c+d+f=540
Furthermore, a is on a straight line with 7x+4, and so on, so
180-(7x+4)= a
176-7x=a
180-(4x+1) = b
179-4x = b
180-(9x-6) = c
186 - 9x = c
180 - (4x+9) = d
171 - 4x = d
180 - (5x+4) = f
176 - 5x = f
a+b+c+d+f = 540
176-7x + 179-4x + 186 - 9x + 171 - 4x + 176 - 5x = 540
888 - 29x = 540
348 = 29x
x = 12

What is the equation in standard form of a line that passes through the point (-2, 5) and has a slope of -0.3?
Answer:
y= −0.3x+4.4
Step-by-step explanation:
A line has a slope of 6 and a y-intercept of 5. What is its equation in slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
The equation in slope-intercept form is y = 6x + 5
Step-by-step explanation:
The slope-intercept form of the linear equation is y = m x + b, where
m is the slopeb is the y-interceptLet us solve the question
∵ A line has a slope of 6
∵ m is the slope of the line
∴ m = 6
∵ The line has a y-intercept of 5
∵ b is the y-intercept
∴ b = 5
→ Substitute the values of m and b in the slope-intercept form
∵ y = m x + b
∴ y = 6x + 5
∴ The equation in slope-intercept form is y = 6x + 5

Answer:
x1 = 0.52
x2 = -10.1
x3 = 0.97
Step-by-step explanation:
From the question;
x1 = 1 - 3/(x0)^2
x0 = -2.5
x1 = 1- 3/(-2.5)^2
x1 = 1 -0.48
x1 = 0.52
x2 = 1 - 3/(x1)^2
x2 = 1 - 3/0.52^2
x2 = 1 - 11.1
x2 = -10.1
x3 = 1 - 3/(x2)^2
x3 = 1- 3/(-10.1)^2
x3 = 0.97

solving systems of linear inequalities
Answer:
YES. (2, 7) is a solution of the system.
Step-by-step explanation:
System of linear inequalities has been given as,
y ≥ -x + 1 --------(1)
y < 4x + 2 ------(2)
If (2, 7) is a solution of the given system of inequalities, it will satisfy both the inequalities.
By substituting the coordinates of point (2, 7) in inequality (1),
7 ≥ -2 + 1
7 ≥ -1
True.
By substituting the coordinates of point (2, 7) in inequality (2),
7 < 4(2) + 1
7 < 9
True.
Therefore, point (2, 7) lie in the solution area of system of inequalities.
YES. (2, 7) is a solution of the system.
