Answer: x=5
Step-by-step explanation:
Simplify to 2x+ 3x -5 to 5x-5
5x- 5 = 20
Add 5 to both sides.
5x= 20+5
Simplify 20+5 to 25.
5x= 25
Divide both sides by 5.
x= 25/5
Simplify 25/5 to 5.
x=5

so we add the number that it grew to the size it was before.
Answer: 1.85 + x = 5.30
Step-by-step explanation: If we know that Ethan planted a tree that was 1.85 meters tall from the start and several years later it's 5.30 meters tall, we know that something must have been added to the 1.85 in order to get 5.30 meters tall. Since we don't know what that value is, we can use x.
X is an example of a variable. A variable is just a letter that represents any number so in this case, it represents how much the tree has grown over a time period of several years.
So we can write this as 1.85 + x = 1.30.

I used the quadratic formula
Answer:
B
Step-by-step explanation:
Given
(x + 5)² = 48 ( take the square root of both sides )
x + 5 = ± [tex]\sqrt{48}[/tex] = ± [tex]\sqrt{16(3)}[/tex] = ± 4[tex]\sqrt{3}[/tex] ( subtract 5 from both sides )
x = - 5 ± 4[tex]\sqrt{3}[/tex] → B

On a coordinate plane, a red line, labeled g of x, begins on a negative slope, crosses the x-axis at (negative 2, 0), the y-axis at (0, negative 2), and crosses the x-axis on a positive slope at (2, 0). A straight blue line with a negative slope, labeled f of x, crosses the y-axis at (0, 2) and the x-axis at (2, 0). Which statement is true regarding the functions on the graph? f(2) = g(2) f(0) = g(0) f(2) = g(0) f(0) = g(2)
Answer:
a
Step-by-step explanation:
because the lines crossover at to and in the parentheses so the x is it which makes a right.
The statement that is true regarding the functions on the graph is that f(2) = g(2).
What is a graph functions?Graphing functions is known to be the drawing of any curve that shows the function that can be seen on the coordinate plane.
Note that If a curve (graph) stands for a function, then all the point on the curve is one that satisfies the equation of the function.
Note that the linear function Since the x - axis starts with 2 it is also true to say that the y axis will also have a positive value and as such, The statement that is true regarding the functions on the graph is that f(2) = g(2).

-30 = 5(x+1)
Answer:
−30=5(x+1)
Step 1: Simplify both sides of the equation.
−30=5(x+1)
−30=(5)(x)+(5)(1)(Distribute)
−30=5x+5
Step 2: Flip the equation.
5x+5=−30
Step 3: Subtract 5 from both sides.
5x+5−5=−30−5
5x=−35
Step 4: Divide both sides by 5.
5x5=−355
x=−7
Answer:
x=−7
Answer:
x = -7
Step-by-step explanation:
Since this problem has the distributive property, we can simplify the problem.
-30 = 5x + 5
Now we have to subtract 5 from both sides because of the +5.
-35 = 5x
To find the answer, we have to move all the real numbers to one side, the variable on the other. To do this, we can simply divide both sides by 5.
-7 = x
x = -7

Answer:
x = 12.6
Step-by-step explanation:
When you have one fraction equated to another one, the means-extremes property allows you to cross multiply, as follows:
[tex]\frac{a}{b} = \frac{c}{d} [/tex]
can be rewritten as:
a*d = c*b

What is the solution to the inequality |X-4 <3?

O 1
X<-7 or x<-1
O x> 1 or x<7
Answer:
|X - 4| < 3 is equivalent to 1 < X < 7.
Step-by-step explanation:
Given
|X - 4| < 3
Required
Solution of the inequality
The options are not properly presented. However, I'll solve the question without considering the options.
To simplify the given inequality, it's worth knowing that the absolute function of any inequality returns the positive form of any value it takes (whether negative or positive).
Since, we've understood that the absolute can take negative of positive, the above inequality can take the following form
-3 < X - 4 < 3
Add 4 through
4 - 3 < X - 4 + 4 < 3 + 4
1 < X < 7.
Hence, |X - 4| < 3 is equivalent to 1 < X < 7.

The required line is perpendicular bi sector. So it goes through the midpoint of AB. Find the midpoint of AB
Midpoint [tex](\frac{x_{1}+x_{2}}{2} , \frac{y_{1}+y_{2}}{2})\\[/tex]
Midpoint of AB = [tex](\frac{-2 + [-4]}{2} , \frac{8+2}{2})[/tex]
[tex]=(\frac{-6}{2} , \frac{10}{2})\\\\=(-3 , 5)[/tex]
Find the slope of AB, [tex]m_{1}[/tex]
slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\[/tex]
[tex]=\frac{2 - 8}{-4-[-2]}\\\\=\frac{-6}{-4+2}\\\\=\frac{-6}{-2}\\\\=3[/tex]
Slope of the perpendicular line to AB = [tex]\frac{-1}{m_{1}}[/tex] = -1/3
The required line passes through (-3, 5) and has slope -1/3
Equation of required line : y - y1 = m (x -x1)
[tex]y - 5 = \frac{-1}{3} (x - [-3])\\\\y-5=\frac{-1}{3} ( x +3)\\\\y-5=\frac{-1}{3}x + 3 *\frac{-1}{3}\\\\y-5=\frac{-1}{3}x-1\\\\y=\frac{-1}{3}x-1+5\\\\y=\frac{-1}{3}x + 4[/tex]
