2x=17 what is the value of x
Answers
Answer: X = 8.5
Step-by-step explanation:
2x = 17
divide by 2
x = 8.5
By solving the value we get the value of x that is equal to 8.5.
Calculating the value of x:When considering unknown values, the value of x is used. In algebra, the letter "x" is frequently used to denote an unknown value. It's called a "variable" or an "unknown" in other circumstances.[tex]\to[/tex] 2x=17

Elijah is keeping track of his baby sister’s shoe size at different ages throughout her childhood. Which statements about the relationship between Elijah’s sister’s shoe size and her age are true? Select all that apply.
A. The relationship is a continuous function.
B. The relationship is a discrete function.
C. The domain and range are restricted to positive numbers.
D. The domain and range are restricted to positive integers.
Answers
Answer:
B and D
Step-by-step explanation:
The function is the relation between the sister's shoe size and her age, being age the independent variable x, and the shoe size the dependent variable y.
If we think this through, we'll find out that age is a discrete variable, and shoe size too. Discrete variable refers to those variable that only admit whole numbers, they don't admit decimal numbers. So, in this case, both variables aren't represented by decimal values. So, the relationship is discrete function, punctual data.
Similarly, the function must be restricted to positive integers, because, as we already said, the variable only admit discrete values and we have to add that only should admit positive discrete values, because age cannot be negative, it wouldn't make sense, also shoe size cannot be negative. In this context, negative numbers don't make any sense.

What is the diameter of a circle with the equation (x – 4)2 + (y + 6)2 = 64?
a. 4
b. 8
c. 16
d. 64
Answers
Answer:
16Step-by-step explanation:
step one:
given data
we are given the equation of the circle as
[tex](x -4)2^ + (y + 6)^2 = 64[/tex]----------------1
We know that the general equation for a circle is
[tex]( x - h )^2 + ( y - k )^2 = r^2[/tex]--------------2
comparing the two equations above, we can immediately compare the term on the other side of the equality sign that is
r^2=64
square root both sides
r=√64
r=8
since the radius is 8, hence the diameter is
d=2
r= 2*8

Let p(x) = -2x - 9. If p(x) = -19, find x.
Answers
Answer:
x=5
Step-by-step explanation:
Step 1: Flip the equation.
−2x−9=−19
Step 2: Add 9 to both sides.
−2x−9+9=−19+9
−2x=−10
Step 3: Divide both sides by -2.
Exact Form:
x = 9/17
Decimal Form:
x = 0.52941176…
Edit: "but what are the steps to get 9/17"
1. Move all terms containing x to the left side of the equation.
2. Divide each term by −17 and simplify.

3. (Angles add up to 180)
30x + 4 + 86 = 180
30x + 90 = 180
subtract 90 from both sides
30x = 90
Now divide by 30
x = 3
Check your work ( input 3 to the equation)
30(3) + 4 + 84
90+ 90 = 180 it works :)
4. (Angles are adjacent to each other so there equal)
10x - 3 = 77
add 3 to both sides
10x = 80
divide it by 10
x = 8
Check your work ( input 8 to the equation )
10(8) -3 = 77
80 - 3 = 77
77 = 77

Step-by-step explanation:
A dressmaker needs to cut 9-inch pieces of ribbon from rolls of ribbon that are 9 feet in length. How many 9-inch pieces can the dressmaker cut from 15 of these rolls of ribbon? Before you try that problem, answer the question below.
Step 1
How many inches of ribbon does the dressmaker have, in total?
1 roll of ribbon = 9 feet
15 rolls of ribbon = x feet
x = 15 roll × 9 feet
x = 135 feet
Converting from Feet to inches
1 foot = 12 inches
135 feet = x inches
Cross Multiply
x = 135 × 12 inches
x = 1620 inches
The dress maker cuts 9 inches each
How many 9-inch pieces can the dressmaker cut from 15 of these rolls of ribbon?
15 rolls of ribbon = 1620 inches of ribbons
Hence: = 1620 inches/9
= 180 pieces
She can cut 180 (9 - inch) pieces

True or false Every relation that is linear, must be a function?
Answers
Answer: False
Step-by-step explanation: Let's review the idea of graphs.
For a graph to be linear, it must be a straight line.
To determine whether a given graph is a function,
we use the vertical line test.
The vertical line test tells us that if a vertical line is drawn on a graph,
and hits the graph in more than one place, the graph is not a function.
In fact, this definition tells us the only type of linear graph
that will fail the vertical line test, and that's a vertical line.
Any vertical line that we draw will be both linear and not a function.
One possible graph could be x = 2.
Any vertical line will fit this description.
