Answer:

Step-by-step explanation:

x + y =35

3x + 2y = 90

-3x - 3y = -105

 3x + 2y = 90

-y = -15

y = 15 tacos

x + 15 = 35

x = 20 sandwiches

20 sandwiches = x

15 tacos = y

Answer:

$120.96

Step-by-step explanation:

If there is a 20% discount, she would pay 80% of the price

o.80 x $720 = $576

If there is a tax of 5%, the price she pays increases by 5%

1.05 x 576 = 604.80

If she pays 20% deposit, she would pay

0.2 x 604.80 = $120.96

The best way to select the 100 phone calls would be to randomly select the same amount of phone numbers from each individual type of business. This would make sure that there are no bias choices and would be 100% representative of the overall business market in every single type of business. If you choose the first 100 phone numbers you are choosing from only a handful of the same types of business and leaving out a lot of other types of business. This makes it impossible for the information gathered to be representative of the entire market.

Answer:

A

We can see that the graph is shaded to the left of -1. This means that x is all values less than (<) -1, so C and D are incorrect. Additionally, since the dot is not filled in, this means that x is not going to be equal to -1, which eliminates B. This leaves A, x < -1.

Step-by-step explanation:

Hey there! Your question’s answer would be 18%..

Ok so 9/50 would be 9% out of 50% which is also 100%. If you want to find 50% turn to 100%, multiply 50 with 2 to get 100.

So you do the same thing to 9%. 9 times 2 would be 18%.

Final Result: 9% out of 100% (whole)

9 out of 50 in percentage equivalent terms will be 18% .

Given, 9 out of 50 to a percentage .

Convert fractions to percentage.

Multiply fraction by 100 , the result will be in percentage .

Fraction = [tex]\frac{9}{50}[/tex]

Percentage equivalent

[tex]\frac{9}{50} \times 100\\= 18[/tex]

Thus the percentage equivalent is 18% .

Answer:

Range: 1 > x > 3

Step-by-step explanation:

We are given then function;

y = x³ - 6x² + 9x + 5

dy/dx = 3x² - 12x + 9

We want to find the range of values of x for which dy/dx > 0

Thus;

3x² - 12x + 9 > 0

Using quadratic formula, we have;

x = 1 and x = 3

Let's define the range;

try x = 0

3(0²) - 12(0) + 9 = 9

This is more than 0, so it is part of the solution.

Let's try x = 4

3(4²) - 12(4) + 9 = 9

This is more than 0 so it is part of the solution

Let's try x = 2

3(2²) - 12(2) + 9 = -3

This is less than 9 and so it's not part of the solution.

Thus the range of values of x for which dy/dx > 0 is;

1 > x > 3

Answer:

d = 7.2

Step-by-step explanation:

We can cross multiply the equation to get:

x² - x -6 = x²  + 2x - 3x - 3*2
