Guys I need help in this ​

Mathematics
1 answer:
tigry1 [53]2 years ago
8 0

Answer:

For Table 1, the answer is Not Proportional (B).

For Table 2, the answer is proportional, with y is 3 times x.

Step-by-step explanation:

In table 1, for the first value of x, y is equal to 32, and 32/8 is 4. Remember that, because in order for x and y to be proportional, y/x always has to equal the same number. Let's try the next value. 50/10 = 5, which is obviously not 4, so in table 1, x and y are not proportional. (we didn't even have to try the last one, yay!!!)

In table 2, for the first values 21 and 7, 21/7 is 3. 30/10, the second values, also equals to 3, and so does the last, 39/13 = 3. Therefore, in table 2, x and y are proportional, and y is 3 times x. (7 * 3 = 21, 10 * 3 = 30, and 13 * 3 = 39.)

A car salesman receives a base weekly salary of $150 plus a commission of $325 per car sold. What is the equation that models th
Temka [501]

Given :

Weekly salary , S = $150.

Commission per car , C = $325.

To Find :

The the equation that models the weekly salary of a car salesman.

Solution :

We know it is a quadratic equation :

Let , the equation is , y = mx + c

Here, x is number of car sold in a week.

For  x = 0 ( He will not get commission)

So , Salary is $150 = c .

For x = 1

Salary is $( 150 + 325 ) = $475 = m(1) + c

Therefore , m = $325 and c = $150.

Required linear equation is y = 325x + 150.

Hence, this is the required solution.

Which one of the following statements is true?
kicyunya [14]
The first derivitive is the slope
a positive 1st deriviive is positive slope or increasing
a negaitve 1st derivitive is negative slope or decreasing

the 2nd derivitive tells about the concavity
a negative second derivitive means it is concave down at that point
a positive 2nd derivitive means it is concave up at that point

so

first one is false
2nd is true
3rd is false because it could possibly be a minimum as well

answer is 2nd one

What is the solution to the equation? 12 = |X| - 3 X= -36 or 36 X= -9 or 9 X = -4 or 4 X = -15 or 15​
quester [9]

Answer:

x = -15 or 15

Step-by-step explanation:

We can simplify |x| - 3 = 15 to |x| = 15 because we can add 3 on both sides due to -3 being outside of the absolute value bars. Next, we can say that x is either 15 or -15 because of the absolute value (|15| is equal to 15 and |-15| is also equal to 15).
