Answer:
The domain is -oo < x < oo or (-oo,oo)
Step-by-step explanation:
Sometimes it helps if you draw this out on a number line or graph the equation! :)
Domain is how far x goes. As in this case x is infinite both ways.
Answer these below
a) 3 ⋅ 1/3 =
b) 10 ⋅ 1/10 =
c) 19⋅ 1/19 =
Answer:
a) 3/3=1
b) 10/10=1
c) 19/19=1
Step-by-step explanation:
yes
a) 1
b) 1
c) 1
Step-by-step explanation:3 x 1/3 =
First we should understand that 3 in fraction form is 3/1.
(3 divided by 1 is three)
So we can rewrite this as;
3/1 x 1/3 =
Now just multiply across
3/1 x 1/3 = 3/3 = 1
Repeating this same logic we'll come across the following answers
10 x 1/10 = 10/10 = 1
19 x 1/19 = 19/19 = 1
Hope this helps

What is the slope of the line shown in the graph? The answer to choose from: -2, -1, 1/-2, 1/2. I put -2 but I don’t think I’m right-
(x-y)(x-y+1)² -2(x-y)(x-y+1)+x-y
help ASAP pleasee!!
Step-by-step explanation:
If u are looking for factorization this is the way
(x-y)(x-y+1)² -2(x-y)(x-y+1)+(x-y)=
(x-y)[(x-y+1)^2-2(x-y+1)+1]=
(x-y)[(x-y+1)^2-2(x-y+1)+1^2]=
(x-y)[(x-y+1)-1]^2=(x-y)(x-y+1-1)^2
(x-y)(x-y)^2=
(x-y)^3

what is the solution for w in the equation
w+1/2=1/4w+2
options
w=2
w=9/8
w=4
w=10/3
Answer:
Subtract 1/2 from both sides of the equation.
w=1/4w+1 1/2
Multiply both sides by 4
4w=w+6
Subtract w from both sides
3w=6
Divide both sides by 3
w=2
Check answer
2+1/2=1/4(2)+2

Step-by-step explanation:
slope= -1/2
y intercept= 2
y=mx+b
m is the slope and b is the y intercept.
9514 1404 393
Answer:
slope: -1/2y-intercept: 2Step-by-step explanation:
The slope-intercept form of the equation for a line is ...
y = mx + b
where m represents the slope, and b represents the y-intercept. To find the slope and y-intercept of your equation, compare it to this form. Matching the patterns, you see that ...
m = -1/2
b = 2
The slope is -1/2; the y-intercept is 2.
__
The graph can be made by locating the y-intercept at y=2 on the y-axis. Then locate another point that is over 2 and down 1* from the y-intercept. The coordinates of that point will be (2, 1). Draw the line through those two points.
_____
* The slope is often described as "rise"/"run", that is, the vertical change (rise) divided by the corresponding horizontal change (run). A slope of -1/2 means the "rise" is -1 units (down 1) while the corresponding "run" is 2 units (to the right).
Solve for m.
5m+72=−2m+52
Drag and drop the answer into the box.
Answer:
m= -20/7
Step-by-step explanation:
5m+72=−2m+52
Add 2m to each side: 7m + 72 = 52
Subtract 72 from each side: 7m = -20
Divide each side by 7: -20/7

Step-by-step explanation:
What do you have to know about any segments and angles in a figure to decide whether the figure has line symmetry?
Answer:
Explained below.
Step-by-step explanation:
When drawing line of symmetry on a figure and reflecting, we have to know that pairs of segments in that figure must have the same length while pairs of angles must have the same measurement. This is to ensure that half of that figure must concise with the other half part of it when that figure is folded across a line of symmetry.
Solve for x.
5x – 4 > 12
AND 12x + 5-4
Step-by-step explanation:
5x - 4 > 12 adding 4 to both sides;
5x - 4 + 4 > 12 + 4
5x > 16 dividing both sides by 5;
x > 16/5
12x + 5-4
12x + 1

Logarithms:
The number of cells in an embryo as it develops in the womb is modeled in the form [tex]f(x) = 2^{kt}[/tex] , where T is the time in months. If the fetus is estimated to have 32 cells in the first month, how many cells does a newborn have on average?
Answer:
2^45 or ≈ 3.5*10^13Step-by-step explanation:
Given equation
f(t) = 2^(kt)f - number of cells, t - number of months, k- coefficientWe got 32 cells in the first month. It means:
t = 1, f(1) = 32Using these numbers we can find the coefficient k:
32 = 2^(k*1) 2^5 = 2^kk = 5Then the equation becomes:
f(t) = 2^(5t)Average time is 9 months, we can calculate the number of cells:
f(9) = 2^(5*9) = 2^45 ≈ 3.5*10^13select the correct answer what is the solution for X in the equation
2x-3x-18= -18+2x+5x

Okay, so what you're basically doing is finding out how much salsa is in the pot. To me, it seems like a trick question.
If two quarts is 2 1/2 of salsa, and they're asking you how much salsa is one quart, you would probably want to simplify 2 1/2. That would come to 2/5. 2/5 simplified would be 0.4 in fractions would total to 1 1/4. That would be your answer.

Tell whether the value is a solution of the
- 5 = QS)-1; S = 10
Answer:
S=− [tex]\frac{4}{Q}[/tex]
Step-by-step explanation:
−5=(QS)−1
Swap sides so that all variable terms are on the left hand side.
QS−1=−5
Add 1 to both sides.
QS=−5+1
Add −5 and 1 to get −4.
QS=−4
Divide both sides by Q.
[tex]\frac{QS}{Q}[/tex]=[tex]\frac{-4}{Q}[/tex]
Dividing by Q undoes the multiplication by Q.
S= [tex]\frac{-4}{Q}[/tex]
Divide −4 by Q.
S=− [tex]\frac{4}{Q}[/tex]

A skeptical paranormal researcher claims that the proportion of Americans that have seen a UFO is less than 2 in a thousand. Identify the type I error for the test.
A. Fail to reject the claim that the proportion of Americans that have seen a UFO is equal to 2 in a thousand when that proportion is actually less than 2 in a thousand.
B. Reject the claim that the proportion of Americans that have seen a UFO is equal to 2 in a thousand when that proportion is actually 2 in a thousand.
C. Reject the claim that the proportion of Americans that have seen a UFO is equal to 2 in a thousand when that proportion is actually less than 2 in a thousand.
D. Fail to reject the claim that the proportion of Americans that have seen a UFO is equal to 2 in a thousand when that proportion is actually greater than 2 in a thousand.
Answer:
The correct option is (B).
Step-by-step explanation:
A type-I-error occurs when we discard a true null-hypothesis (H₀).
The hypothesis in this case are:
H₀: The proportion of Americans that have seen a UFO is 0.002, i.e. p = 0.002.
Hₐ: The proportion of Americans that have seen a UFO is less than 0.002, i.e. p < 0.002.
A type I error will be committed, if we reject the claim that the proportion of Americans that have seen a UFO is equal to 2 in a thousand when that proportion is actually 2 in a thousand.
The correct option is (B).
Let f(x) = 2x + 1, g(x) = 3x - 2. Find the function (f - g)(x)
Answer:
Step-by-step explanation:
I thought they corrected this problem. Apparently not. I have to change eff(x). Change it to y
You can read this as y - g(x)
y - g(x) = 2x + 1 - 3x + 2
y - g(x) = -x + 3
