Bobby is 5 less than Kylie's age. Their combined
age is 43. How old is Kylie?
Answer:
Kylie is 24 years old
Step-by-step explanation:
kylie = x
Bobby=x-5
x+x-5=43
2x-5=43
2x=43+5
2x=48
X=24 years old
19
If you subtract 5 off of 43 and divide it by two you find Kylie's age. The reason you divide by two is because there are two people and it is a combined age, meaning you would divide by two.

W-20.5=8 please help me
This is just the same as asking you what number when subtracted by 20.5 will give you an answer of 8. The answer would obviously be 8+20.5=28.5 so w=28.5.
We can also do it in a more algebraic way. By adding 20.5 to both side of the equation which won't change the value.
w-20.5+20.5=8+20.5
w=28.5
Any questions just ask me in the comments of this question :)

y = x -1
y = -2x -4
Answer:
y=x-1
y=-2x-4
although I cant summon a graph for this one, I can give cords
for first graph (-2,-3),(-1,-2),(0,-1), (1,0),(2,1)
For second graph the slope is down 2 over 1, and begins at (0,-4).
(-2,0)(-1,-2),(0,-4),(1,-6),(2,-8)
Let's solve for x.
y=x−1
Step 1: Flip the equation.
x−1=y
Step 2: Add 1 to both sides.
x−1+1=y+1
x=y+1
Answer:
x=y+1
---------------------------------
Let's solve for x.
y=−2x−4
Step 1: Flip the equation.
−2x−4=y
Step 2: Add 4 to both sides.
−2x−4+4=y+4
−2x=y+4
Step 3: Divide both sides by -2.

Write the equation of a line with an undefined slope that passes through the point (-6,3)
Answer:
x = -6
Step-by-step explanation:
A line with an undefined slope is vertical and is always represented by the equation x = a number. That number, whatever it may be, represents the x-value of all the points it intersects. Thus, take the x-value of the point (-6,3) and put it into the equation. So, the equation must be x = -6.

Calculate 48 x 3/8 choose the numbers to complete the equation
Answer:
1. Choose: 3
2. Choose: 144
3. Choose: 18
Step-by-step explanation:
The first thing you do is multiply 48 * 3/8= 18. Then multiply 48 * 1/8= 6. Then divide both answers to get 3, so 48 * 1/8 * 3.
Then to find the second Choose option, you know that 48 * 1/8 * 3= 18; so 18 * 8= 144(to check your answer, divide 144/8 = 18).
Finally, to find the third Choose option, you divide the fraction 144/8 = 18.

HELP ILL GIVE BRAINLYIST
Answer:
560
Step-by-step Explanation
Since, 476 students make 85%.
Therefore, let x students will make 100%.
[tex] \frac{476}{85} = \frac{x}{100} \\ \\ x = \frac{476 \times 100}{85} \\ \\ x = \frac{47600}{85} \\ \\ x = {560} [/tex]

Find the value of the missing Angles:
Answer:
Angle 1 is 58 and Angle 2 is 32 because all triangles equal to 180 and where the lines bisect creates a 90 degree angle in each triangle. Add 90 and 32 together, then minus 122 from 180 and you get angle 1 and the angle across from angle 1. For angle 2, add 58 and 90, then subtract that from 180. You'll end up getting 32

Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.
Answer:
y - 3 = 2(x + 1)
Step-by-step explanation:
First, use rise over run to find the slope
(y2 - y1) / (x2 - x1)
(3 + 7) / (-1 + 6)
10 / 5
= 2
Now, plug in the slope and a point into the point slope formula:
y - y1 = m(x - x1)
y - 3 = 2(x + 1)
So, the equation in point slope form is y - 3 = 2(x + 1)

Which equation has the greatest rate of change?
y=12x-7
y=5x+9
y=4x+12
y=X+36
Answer:
y=12x-7
Step-by-step explanation:
Rate of change is the same thing as slope which can be found by looking at the value before the x. Since 12 is the largest number, it has the largest rate of change.
I’ve been confused on this problem for awhile :(

True or False: An asymptote is a line in which a graph gets close to but never crosses.
True
False
Answer:
True
Step-by-step explanation:
An asymptote is, essentially, a line that a graph approaches, but does not intersect. For example, in the following graph of y = 1x y = 1 x , the line approaches the x-axis (y=0), but never touches it. No matter how far we go into infinity, the line will not actually reach y = 0, but will always get closer and closer.
The statement is true.
What is an asymptote?Asymptote is a line that a curve approaches as it moves towards infinity. Asymptotes. The curves visit these asymptotes but never overtake them.
An asymptote is a line along which the values of a function approaches but never reach, such that one or both of the or coordinates tend to positive or negative infinity. Therefore, the graph of a rational function never intersects any of its asymptotes.
Hence, the statement is true.

Step-by-step explanation:
Answer:
1.) B.) 30
2.) D.) 2.38
Step-by-step explanation:
1.) The answer is B because when the encyclopedia first went live there were 30 articles in it.
2.) The answer is D because the product first started out as $38⁰⁰ and each year it is decreasing half the amount of the year before it and it does this for 4 years:
Start: Year 1: Year 2: Year 3: Year 4:
$38⁰⁰ ÷ 2 = $19 ÷ 2 = $9⁵⁰ ÷ 2 = $4⁷⁵ ÷ 2 = $2³⁸ <--- I rounded up because 2.375 is closer to 2.38

Answer:
Step-by-step explanation:
1.How to find the longer leg of a 45 45 90 Triangle?
ans : If you know the length of one of the legs of a 45-45-90 triangle, the other leg has the same length. For this triangle, the other leg has a length of 8*sqrt(2) units. The hypotenuse's length can be found by multiplying the leg's length by sqrt(2).
Stephen purchased a guitar, which was originally priced at $80 but
discounted at 25%. He also had to pay 5% sales tax. What amount did
Stephen pay to purchase the guitar? *
Answer:
57 dollars
Step-by-step explanation:
1. Solving the 25% discount
25% = .25
80 x .25 = $20
80 - 20 = $60
** We subtracted 80 from 20 because 25% of 80 is 20 BUT We're taking 25% OFF of 80 because it was a discount.
2. Solving the 5% Tax
5% = .05
$60 x .05 = 3
$60 + 3 = $63
**Adding tax to the discounted price
