Answer:
0
Step-by-step explanation:
Zero is a rational number, and we know that the integer 0 can be written in any one of the following forms. ... Thus, 0 can be written as, where a/b = 0, where a = 0 and b is any non-zero integer. Hence, 0 is a rational number and not an integer.
1/3× 21/4-11/2÷22/5?? .btw they are improper fractions
[tex] \frac{1}{3} \times \frac{21}{4} - \frac{11}{2} \div \frac{22}{5} \\ = \frac{1}{3} \times \frac{21}{4} - \frac{11}{2} \times \frac{5}{22} \\ = \frac{1}{3} \times \frac{21}{4} - \frac{5}{4} \\ = \frac{7}{4} - \frac{5}{4} \\ = \frac{2}{4} \\ = \frac{1}{2} [/tex]

Which of the following expressions is equivalent to 4(2x+y) ?
Answer:
what expressions
Step-by-step explanation:
Answer:
Step-by-step explanation:
First expand the expression so you know the coefficients of x and y.
4(2x+y+2y) = 4(2x+3y) = 8x+12y
8x+12y = 8x+12y
6x+7y ≠ 6x+12y
8x+y+2y = 8x + 3y ≠ 8x+12y
8x+4y+8y = 8x+12y = 8x+12y

Answer:
1 bat : 0 hits
Step-by-step explanation:
To get this unit rate all you have to do is divide both sides by 4.
(4/4) : (0/4) = 1:0
We get the same number of hits as in the original problem because 0 divided by any number (other than 0) will always equal 0.

Help me with the question in the image it’s geometry
Answer:
<BAC=100°
Step-by-step explanation:
<ACB = <DCE - vertical angles are congruent
<ACB = 45° - substitute <DCE = 45° <ACB = <DCE
<ABC + <ACB + <BAC = 180° - angle sum theorem
35° + 45° + <BAC = 180° - substitute <ABC = 35°, <ACB = 45° INTO <ABC + <ACB + <BAC = 180 °
35°+ 45° + <BAC = 180°
180° - 80° = 100
What is the equation of the line parallel to the line with the equation −x+3y=−3
that passes through the point (1, –6)
Answer:
y = 1/3x - 19/3
Step-by-step explanation:
3y = x -3
y = 1/3x -3
Slope = 1/3
Point= (1,-6)
y-intercept = -6 - (1/3)(1) = -6 - 1/3 = -19/3

writing carla has already written 10 pages of a novel she plans to write 15 additional pages per month until she is finished A.write an equation to find the total number of pages P written after any number of months MB. graph the equation on the grid at the rightC. find the total number of pages written after 5 months
Answer:
P = 5M + 10
Step-by-step explanation:
15 pages/month * M months + 10 pages = P pages
5 Months = 5*15 + 10 = 85 pages

What does x equal
Answer:
X=18
Step-by-step explanation:
To isolate X you need to get rid of the -15 to do that you can add 15 on both sides of the equation resulting in 3x=54 now you need to divide both sides by 3 to get x on its own which is X=18.

Solve the equation for the y-value and choose whether it is a direct variation or inverse variation
xy = 7
Answer: Choice B
y = 7/x
inverse variation
=========================================================
Explanation:
We divide both sides by x to isolate y. That's how we go from xy = 7 to y = 7/x
This is an inverse variation because it's in the form y = k/x. The constant is k = 7.
Are the two lines parallel?
If so, then what is the slope?
Yes, and the slope is 2.
Yes, and the slope is 5/2
res, and the slope is 2/5
No, They are not parallel
Answer and Step-by-step explanation:
(3rd option) The two lines are parallel, and they have a slope of [tex]\frac{2}{5}[/tex].
First, we can see that the two lines look parallel (meaning that if you were to go beyond what the graph shows (unless the graph shows an intersection), the lines at no point will intersect).
Second, If you found the slope of each line as well, (slope = rise over run, count up and then count right in this scenario from any point), they are the same, meaning they must be parallel to each other.

How many ways can you make the number 2? (Using consecutive numbers)
Answer
For any two consecutive odd numbers, the difference is 2. For example, 3 and 5 are two consecutive odd numbers, their difference = 5 - 3 = 2. For any two consecutive even numbers, the difference is 2. For example, 6 and 8 are two consecutive even numbers, their difference = 8 - 6 = 2.

Hello there!
To find the area of this rectangle, we must multiply the length times the width:
A=[tex]3\frac{1}{5} *\frac{7}{8}[/tex]
Let's convert the mixed number into an improper fraction:
[tex]\frac{16}{5} *\frac{7}{8}[/tex]
Do you see what I see?
16 and 8 can be reduced. Divide by 8:
[tex]\frac{2}{5} *\frac{7}{1}[/tex]
Now multiply:
[tex]\frac{14}{5} \\[/tex]

hi, can anyone help with b) and c)?
Answer:
steps below
Step-by-step explanation:
From the graph: parabola pass (0,4) (3,4) (1,2)
equation: y = ax² + bx + c
(0,4): c = 4
(3,4): 9a + 3b + 4 = 4 9a+3b = 0 3a + b = 0 ... (1)
(1,2): a + b + 4 = 2 a+b = -2 ... (2)
(1)-(2): 2a = 2 a = 1
(2): b = -3
parabola equation: f(x) = x² - 3x +4
(a) f(3) = 3² - 3*3 + 4 = 4
(b) normal line: parallel to tangent line y = 3x -5 at (3,4)
slope of line N: -1/3 pass (3,4)
equation of N: (y-4)/(x-3) = -1/3 y-4 = -1/3 x + 1
line N: 1/3 x + y - 5 = 0
