Write an equation representing the relationship of 10:20 shown in the graph
Answers
Answer:
[tex]20=2(10)[/tex]
Step-by-step explanation:
10:20 is a good point that passes a line to another.
This graph is a linear graph.
The linear equation is
[tex]y=mx+b[/tex]
[tex]y[/tex] = 20 (the y coordinate in the graph)
[tex]m[/tex] = slope
[tex]x[/tex] = 10 (the x coordinate in the graph)
[tex]b[/tex] = y-intercept
Finding slope
To find the equation, we'll need to plug in the values in the formula. To find slope using two points, use the formula, then plug in the values:
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
(10, 20) and (20, 40)
[tex]=\frac{40-20}{20-10}[/tex]
[tex]= \frac{20}{10}[/tex]
[tex]\bold{m= 2}[/tex]
Finding the y-intercept
You have to find the slope first before finding the y-intercept. So, plugin one of the two points we used to find the slope into the formula and solve for [tex]b[/tex]
(10, 20)
[tex]20=2(10)+b[/tex]
[tex]20=20+b[/tex]
[tex]20-20=20-20+b[/tex]
[tex]\bold{b=0}[/tex]
The y-intercept is zero, and when it is, you do not add it since zero is nothing.
The equation is [tex]20=2(10)[/tex]

Answer:
a) x = 11, b) x = 2/5, c) x = 1/2
Step-by-step explanation:
a)
11 x 11 x 11 = 1,331
Therefore, the answer is x = 11
b)
Reduce the fraction by the highest number 64 and 1000 go into. (which is 8)
So it'll turn into [tex]\sqrt[3]{\frac{8}{125} }[/tex]
Then reduce the fraction again, which will leave you with [tex]\frac{2}{5}[/tex]
Therefore, x= 2/5
c)
Reduce the fraction using 27.
That will give you [tex]x^{3} = \frac{1}{8}[/tex]
Then simplify the equation, which will give you [tex]x=\frac{1}{2}[/tex]

HELP PLEASE! Write an equation with variables on both sides that has a single solution "-1." Explain how to find that solution
Answers
ANSWER : HEY MATE
The solution to the equation 2x + 3 = x + 2, where x = -1, is found by isolating the variable "x" and simplifying the equation step by step
Let's create an equation with variables on both sides that has a single solution of "-1."
Let's call the variable "x."
An equation that meets these criteria is:
2x + 3 = x + 2.
We want to isolate the variable "x" on one side of the equation to find the solution.
Start by simplifying both sides of the equation.
On the left side, we have; 2x + 3;
And, on the right side, we have x + 2.
Now solve the equation as;
2x + 3 = x + 2
Subtract x on both sides;
2x - x + 3 = 2
x + 3 = 2
Subtract 3 on both sides;
x = 2 - 3
x = - 1
So, the solution to the equation 2x + 3 = x + 2, where x = -1, is found by isolating the variable "x" and simplifying the equation step by step.

Answer:
13 square units
Step-by-step explanation:
Look at image attached
Divide shape into two rectangles
Rectangle 1:
width: 2 units
length: 5 - 1 = 4 units
AREA: 2 x 4 = 8 sq. units
Rectangle 2:
width: 1 units
length: 5 units
AREA: 1 x 5 = 5 sq. Units
Combine area of rectangles:
8 + 5 = 13 sq. Units
