Answer:
A
Step-by-step explanation:
You must multiply the number your buying by the price then you need to multiply by 1.07 because you need 7% or .07 to get the tax but you want to add that to the old number so you need a 1 in front so the answer is c(p) = 1.07(3p) however you still need the $15 gift card so instead you add the 7% into the three dollars you are multiplying by the number then subtract the 15 dollars because you aren't really paying. The reasonable domain is 0 1 2 3 4 because the number 5 would be over the 15 dollar limit.
please help me asap will appreciate it a lot
slope of a line passing through points A (3, 2) and B (-2, -3)?
Answer:
1
Step-by-step explanation:
So for this type of problem we use the formula [tex]m= \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex] with each variable (besides m which is slope) representing a different coordinate. (e.g. -3 could be [tex]y_{2}[/tex] in this case.) First, let's define which is which:
(3,2): [tex]x_{1}, y_{1}[/tex]
(-2,-3): [tex]x_{2}, y_{2}[/tex]
Now we need to replace the variables with their known values: [tex]m=\frac{-3-2}{-2-3}[/tex]
Next, let's do the subtraction to simplify: [tex]m=\frac{-5}{-5}[/tex]
And we can complete the division (all fractions are division!) to simplify even further: [tex]m = 1[/tex]
Therefore, the slope of the line passing through the points (3,2) and (-2,-3) is 1.
X+5x-3x-4 simplified?
Answer:
3x-4
How to find it:
x + 5x - 3x - 4
Add like terms
6x - 3x - 4
Add like terms
3x - 4
Answer:
3x-4
Step-by-step explanation:
Combine like terms, x + 5x gives you 6x but then subtract 3x and you have only 3x.
Keep 4 the same and your answer is 3x-4

Determine if -81.42 is rational or irrational. If it is rational, write the number as a ratio of two integers.
Answer:
-81.42 is a rational number
Step-by-step explanation:
[tex] - 81.42 \\ \\ = - \frac{8142}{100} \\ \\ = - \frac{8142 \div 2}{100 \div 2} \\ \\ = - \frac{4071}{50} \\ \\[/tex]
Answer: It is a rational number.
A rational number is a number that can be represented as a fraction.
The fraction can be: [tex]- \frac{4071}{50}[/tex] because:
[tex]-\frac{81.42}{100}[/tex] ÷ 2 = [tex]\frac{40.71}{50}[/tex]
The answer is yes, it is rational.

Find KJR
Options: 4
61
55
50
Answer:
61
Step-by-step explanation:
Let's see what to do buddy...
_________________________________
KJI = KJR + RJI
So :
172° = ( 6x -5 )° + ( 12x -3 )°
172° = 18x - 8°
Subtract the sides of the equation plus 8°
180° = 18x
Divided the sides of the equation by 18
x = 180/18
x = 10°
_________________________________
So we have :
KJR = 6x -5 = 6(10) - 5 = 60 - 5 = 55°
KJR = 55°
_________________________________
And we're done.
Thanks for watching buddy good luck.

what is an equation of the line that passes through the points (-6,2) and (6,-2)
Answer:
y = -1/3 x + 8/3 or 3y = -x + 8
Step-by-step explanation:
m = (-2 - 2) / [(6 - (-6)]
= -4 / 12
= -1/3
Use (-6, 2) and substitute in the formula:
y = mx + b
2 = -1/3 (2) + b
2 = -2/3 + b
2 + 2/3 = b
8/3 = b
y = mx + b
y = -1/3 x + 8/3 or 3y = -x + 8

Step-by-step explanation:
In an electrical circuit, the current is related to the power and resistance according to the rule I=pR−−√, where I represents the current (measured in amps), P represents power (measured in watts), and R represents resistance (measured in ohms). What is the electrical power drawn by a device that has a resistance of 15 ohms with a current of 4 amps?
Answer:
[tex]P=0.27\,\,watts[/tex]
Step-by-step explanation:
Consider the formula: [tex]I=PR[/tex]
Here, [tex]I[/tex] represents the current (measured in amps), P represents power (measured in watts), and R represents resistance (measured in ohms).
Resistance = 15 ohms
Current = 4 amps
To find electrical power drawn by a device, put [tex]R=15\,,\,I=4[/tex]
So,
[tex]4=15P\\P=\frac{4}{15}=0.27\,\,watts[/tex]
Can somebody help me with this?
Step-by-step explanation:
Hey there!
By looking through figure, l and m are parallel lines and a transversal line passes through the lines.
Now,
7x + 12° = 12x - 28°( alternate angles are equal)
12°+28° = 12x - 7x
40° = 5x
[tex]x = \frac{40}{5} [/tex]
Therefore, x = 8°
Now,
12x - 28° + 9y - 77 = 180° ( being linear pair)
12×8° - 28° + 9y -77° = 180°
96° - 28° + 9y - 77° = 180°
-9 + 9y = 180°
9y = 180° + 9°
y = 189°/9
Therefore, y = 21°
Therefore, X = 8° and y= 21° .

Answer:
X = 20 degrees
Step-by-step explanation:
so we know that a triangle equals 180 degrees.
We already have 70 degrees so there are 110 degrees left.
Y is a right angle making it a 90 degree angle
110-90 equals 20 making x a 20 degree angle.

A grocery store sells a bag of 6 oranges for $4.20. If Ayden spent $2.80 on oranges, how many did he buy?
Answer:
4 bags of oranges
Step-by-step explanation:
First, we need to find out how much each bag of oranges costs so we divide.
$4.20 divided by 6 equals 0.7 which means that each bag of oranges costs $0.70.
Next we need to find out how much Ayden spent on oranges so we divide 0.70 by 2.80
2.80 divided by 0.70 equals 4.
This means that Ayden bought 4 bags of oranges.
Hope this helps!
Answer:
4 oranges
Step-by-step explanation:
First find the unit rate by dividing the price of 6 oranges by the amount of oranges in the bag. So $4.20÷6=0.7. 0.7 is the price of one orange. Since the dollar amount is small I just divided $4.20 by 2 and got $2.10 for three oranges. The question is asking how much he bought for $2.80 so add another .70 which is one more orange therefore he bought 4 oranges for $2.80
