Determine whether the given point lies on the graph of the inequality. (-1,-3); -x-6y < 19.

in this case, is the point on the graph (yes or no)

Answers

Answer 1
Answer: -x - 6y < 19. 

Point ( -1, -3)   ⇔    x = -1   ,  y = -3
instead of the variables you need to put the values ​​of x and y ( coordinates of the point )
- (-1) - 6*(-3) < 19

we calculate

1 + 18 < 19    record turns mushy

Proposal
the point does not belong to the graph

the answer of 453 divided by 8 is 56,625.
The answer is 453 divide by 56.625...

$450+4%=$???????????????

Answers

In order to solve this, we first need to convert the percentage into a decimal. We can do this by either multiplying the percentage by 100, or (my personal shortcut) just moving the decimal point over two places to the left.

4% = 0.04

Now, we need to multiply the decimal by the amount of money we have.

450 * 0.04 = 18

Now, we need to add this newfound amount to the total, since we are adding the 4%

450 + 18 = 468

$450 + 4% = $468

4.25 cm.
What is the volume of Jamie's ring in cubic centimeters?

Answers

Answer:

1.50 cm^3.

Step-by-step explanation:

The ring will displace its own volume of water.

The increase in height of the water = 4.25 - 4 = 0.25 cm.

Therefore the increase in the volume =  area of the base of the glass * 0.25

= 3 * 2 * 0.25

=  6 * 0.25

= 1.50 cm^3.

This is also the volume of the ring.

Step-by-step explanation:

an electrician has $120 to spend on interior light fixtures. The wholesale price for a 13-watt low-energy lamp is $4. The price for a high-energy lamp is $5. 1)Write the algebraic expression for how much the electrician spends for a units of the low -energy of the low-energy lamp and b units of the high-energy lamp. 2)Write an equation that relates your answer to Exercise 1 to the amount of money the electrician has to spend.

Answers

x = low-energy lamp
y = high-energy lamp

1) 4x + 5y

2) 120= 4x + 5y
Ok, are you ready? Here we go:
First we know that he has 120 dollars, so the first part of the equation is 120 = ?
it equals something, we dont know, so lets find out.
low energy lamp: 13 dollars per unit
High Energy Lamp: 14 dollars per unit
So, 13a (a stands for "a units") and 14b ( b stands for "b units) are the respective equation for the given values, that's question 1
Question 2, we connect the 120 values and the 2 equation we made, so 13a +14b = 120 dollars

Which function is equivalent to y=x2-10x+9? A: Y=(x+5)^2+16
B: Y=(x-5)^2-16
C: Y=(x-5)^2+16
D: Y=(x+5)^2-16

Answers

Answer:

B

Step-by-step explanation:

Given

y = x² - 10x + 9

Using the method of completing the square

add/subtract (half the coefficient of the x- term)² to x² - 10x

y = x² + 2(- 5)x + (- 5)² - (- 5)² + 9

 = (x - 5)² - 25 + 9

 = (x - 5)² - 16 → B

Figure out the equation for each of the multiple choice.

Then you will get the answer .

For example:

a. (x+5)(x+5) +16

= x^2 + 5x+5x+25+16

= x^2+10x+41
