Kira solved the equation in the following way. 7 2 − 2x = 11 2 7 2 − 7 2 − 2x = 11 2 − 7 2 −2x ÷ −2 = 4 2 ÷ − 2 x = −1 Describe the properties of equality that Kira used. The first step is to use the property of equality to combine the constant terms. The second step is to use the property of equality to isolate the variable.
Answer:
the first step is to use the
✔ Subtraction
property of equality to combine the constant terms.
The second step is to use the
✔ Division
property of equality to isolate the variable
Step-by-step explanation:
edge 20 20
The first and second steps used by Kira to solve the equation are;
Subtraction Property of Equality and Division Property of Equality
Understanding Properties of Equality
What Kira wants to solve is;
72 - 2x = 11
The first step is to use the Subtraction property of equality to combine the constant terms. Thus;
72 - 2x - 72 = 11 - 72
-2x = -61
The second step is to use the Division property of equality to isolate the variable to get;
-2x/-2 = -61/-2
x = 61/2

The area of the rectangle shown is at most 140 square centimeters.
a. Write and solve an inequality to find the possible
values of x.
10 cm
b. Based on the answer in part (a), is it possible for
the rectangle to have a length of 15 centimeters?
Explain.
(3x + 2) cm
9514 1404 393
Answer:
a) 10(3x+2) ≤ 140; x ≤ 4
b) no
Step-by-step explanation:
a) The area is the product of length and width. We want that product to be no greater than 140:
10(3x +2) ≤ 140 . . . . your inequality
We can solve this by dividing by 10 first.
3x +2 ≤ 14
3x ≤ 12 . . . . . . subtract 2
x ≤ 4 . . . . . . . . divide by 3; the solution to the inequality
__
b) If the length were 15, the area would be 10×15 = 150, which is greater than 140. The length cannot be 15 if the area is at most 140.

Using the graph below, what is the value of f(8)?
Answer:
0
Step-by-step explanation:
When a problem asks for the value of f(x), find the y value for the given x value. In this instance, since x = 8, y = 0.
From the graph the value of f(8) is 0.
what is Function?In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.
Given:
From the graph we have to find f(8)
This shows that the values of function at x=8
Now, focusing on the x- axis we have keep point on x= 8 then move and where the line touches the functional line we get the result.
Hence, from the graph the value of f(8) is 0.

What equation can be used to create the sequence -3, 2, 7, 12,
Answer:
y=x+5
Step-by-step explanation:
You can tell by looking at the sequence that each number is five more than the previous. With that in mind, you know that, to find the next number in the sequence, you have to add five to the one before it.
Making x the previous number and y the next number in the sequence, you get the equation y=x+5
You can plug pairs from the sequence to check:
2= -3+5
2=2
------------
7= 2+5
7=7
------------
12= 7+5
12=12

Answer:
t = [tex]\sqrt{\frac{-2(h-1)}{a} }[/tex]
Step-by-step explanation:
solve for t
h = -[tex]\frac{1}{2}[/tex]a[tex]t^{2}[/tex] + 1; multiply both sides by -2
-2h = a[tex]t^{2}[/tex] - 2; add 2 to both sides
-2h + 2 = a[tex]t^{2}[/tex]; divide by a
(-2h + 2) / a = [tex]t^{2}[/tex] ; take the square root
t = [tex]\sqrt{\frac{-2(h-1)}{a} }[/tex]
