Answer:
7
Step-by-step explanation:
it is a 16 digit credit card number. Therefore, start from the first digit and double alternating digits. Add them and the non doubled digits. should be divisible by 10. For double digits, they are added to make single digit.
9+3+8+3+9+4+7+5+6+1+5+3+4+3+3+x = 73+x
final number should be divisible by 10.

plsss help me with this:(((
Answer:
First we need our slope equation
Y₂-Y₁/X₂-X₁
So we have our equation now lets plug it in
-9+2/-4-3 (we make it a plus for -9+2 because the two minuses cancel out).
So now we have -7/-7 which is 1 because -7 divided by itself is one. Thereby your answer is A. 1
Same thing for question 12
1-5/2-4
-4/-2 which is 2 because -2 goes into -4 two times so your answer is A. 2
A recipe that would make 18 cupcakes
calls for 4 teaspoons of vanilla. How
many cupcakes is that per teaspoon?
Answer:
Hello there,
Let's solve,
It takes 4tsp for 18 cupcakes
thus for 1tsp it'll be,
= 18/4
= 4 and a half cupcake
That is one teaspoon of vanilla is needed for 4 and a half cupcakes.
All the best!

Is each line parallel, perpendicular, or neither parallel nor perpendicular to the line 4x + 3y = 12? Drag and drop each choice into the boxes to correctly complete the table. Parallel Perpendicular Neither
Step-by-step explanation:
The line given:
4x + 3y = 12, its slope is m = - 4/3Other lines to compare:
-3x + 4y = 8, the slope is m = 3/4, it is perpendicular line as the product of the slopes is - 1;4x + 3y = 31, the slope is m = -4/3, same slope but different y- intercept, it is parallel line;3x + 4y = 12, the slope is m = -3/4, it is neither parallel nor perpendicular;-4x + 3y = - 1, the slope is m = 4/3, it is neither parallel nor perpendicularSlope=m=+4/3
#1
-3x+4y=8m=3/4
Perpendicular#2
4x-3y=31m=-4/3
Parallel#3
3x+4y=12m=-3/4
neither#4
-4x+3y=-1m=4/3

Your 2 year investment of $5,300 earns 2.9% and is compounded annually. What will your total return be?
The total return will be $5611.8
How to calculate the total return?A 2 year investment of $5,300 earns 2.9%
The investment is compounded annually
The total return can be calculated as follows
= 5300 (2.9/100 + 1)
= 5300 (0.029 + 1)
= 5300(1.029)²
= 5300(1.0588)
= $5611.8
Hence the total return is $5611.8

Answer:
I think the first one is correct.
The inequality represent the given graph is y≤7 . Therefore, option B is the correct answer.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
From the given graph, the line passes through (0, -7)
In the given graph the inequality is y≤7
Therefore, option B is the correct answer.
