Use the given equation to determine if the points in the brackets are on the graph
of the line determine by the equation 4x- 3y=-6

{(0,2),(1,3),(4,7),(6,10)}

Answers

Answer 1

The points in the brackets are on the graph are (0, 2) and (6, 10)

How to determine if the points in the brackets are on the graph?

The equation of the line is given as

4x - 3y = -6

The points are given as:

{(0,2),(1,3),(4,7),(6,10)}

Rewrite as

(x, y) = {(0,2),(1,3),(4,7),(6,10)}

Next, we substitute the x and y values in the equation 4x - 3y = -6

So, we have

(0, 2):

4(0) - 3(2) = -6

-6 = -6 ---- true

(1, 3):

4(1) - 3(3) = -6

-5 = -6 ---- false

(4, 7):

4(4) - 3(7) = -6

-5 = -6 ---- false

(6, 10):

4(6) - 3(10) = -6

-6 = -6 ---- true

Hence, the points in the brackets are on the graph are (0, 2) and (6, 10)

Given the binary number 1011, what is the next consecutive binary value? (what happens when you add 1 to 1011)? explain how you arrived at your answer.

Answers

The next consecutive binary value of 1011 = 1100

Binary numbers only consist of two digits: 0 and 1. So there are some specific rules for addition in binary. They are:

0 + 0 = 00 + 1 = 11 + 1 = 10(read as one zero and corresponds to the binary value of 2)1 +1 + 1 = 11 (read as one one one and corresponds to the binary value of 3)

Here 1011 is a binary number and to find the its next consecutive binary value, we have to add 1 to 1011.

i.e., 1 0 1 1 +

------------------

1 1 0 0

The 0 in the one's place is got by adding 1 + 1 = 10 and 1 is supposed to be a carry to the ten's place. The 0 in the ten's place is got from adding this carry 1 and 1, which again gives 10 and 1 is carry to next place. Now 0 + 1 = 1 and finally we get, 1011 + 1 = 1100.

p(x) - 0.9 * f(x) - 50

=0.9 * 3x - 50

=2.7x - 50

Now find the profit for 100 downloads: p(100) = 2.7 * 100 - 50 =220

Answers

It would cost-

$27.50 for the 5 bags of popcorn.$24.50 for the 7 drinks.What is cost?

In common parlance, cost is the monetary value of products and services purchased by producers and consumers.

Cost is the measure of a alternative opportunities foregone when one good or activity is chosen over others in a basic economic sense. This fundamental cost is commonly known as opportunity cost.Total cost refers to all expense incurred in achieving a specific level of output; dividing such total cost by the quantity generated yields average or unit cost.

Total cost = (fixed cost) x Number of units produced.

The cost of a bag of popcorn for $5.50.

The number of popcorn bags bought are 5.

Total cost for 5 bags of popcorn are-

$5.50 ×5 = $27.50.

Thus, Total cost for 5 bags of popcorn bags are $27.50.

The cost of 1 drink is $3.50.

The total number of drinks bought is 7.

Total cost = $3.50×7 = $24.50

f(x) = -x² - 8x - 16; Find ƒ(-3)

Answers

Answer:

f(-3) = -1

Step-by-step explanation:

We can find an unknown y-value by plugging an x-value into a given function.

Function Notation

Before we answer this question, we need to understand the notation of the equation. In function notation, the equation is given in terms of f(x).

"f(x)" represents the y-value of a function at the point "x".

For example, f(-3) represents the value of y when x = -3.

Finding f(3)

As stated above, to find f(-3) we need to plug -3 in for x. *Remember to use PEMDAS when solving.* This creates the new equation:

f(-3) = -(-3)² - 8(-3) - 16

Then, distribute the exponent.

f(-3) = -9 - 8(-3) - 16

Next, multiply.

f(-3) = -9 - (-24) - 16

Distribute the negative.

f(-3) = -9 + 24 - 16

Finally, add the remaining terms.

f(-3) = -1

This means that when x = -3, y or f(-3) = -1.

one and one seventh pounds

two over 49 pounds
three sevenths pounds

Answers

Using proportions, the number of pounds that will be needed for a single serving is: one and three seventh pounds.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

The number of pounds for 3 people is given by:

[tex]3 \frac{3}{7} = 3 + \frac{3}{7} = \frac{24}{7}[/tex]

Hence, for one person, the number of pounds can be divided by three(multiplied by 1/3), hence:

[tex]\frac{24}{7} \times \frac{1}{3} = \frac{24}{21}[/tex]

24 divided by 21 has a quotient of 1 and remainder of 3, hence as a mixed number, the amount is:

What is indefinite integral?A function that performs the antiderivative of another function is known as an indefinite integral.

A differentiable function F whose derivative is equal to the original function f is referred to as an antiderivative, inverse derivative, primitive function, primitive integral, or indefinite integral of a function f in calculus.

So,

KEEP IN MIND ----> *Square root of a number is a value, which on multiplication by itself gives the original number. The square root is an inverse method of squaring a number.*

Alright so the first equation C^2 - 49 = 0

Step 1 : Add 49 to both sides

C^2 - 49 + 49 = 0 + 49

C^2 = 49

Step 2 : Take the square root

(squ root) C^2 = (squ root)49

C = +/- (squ root) 49

Final answer ---> C = 7 OR C = -7

2.) 4S^2 - 100 = 0

Step 1 : Add 100 to both sides

4S^2 - 100 + 100 = 0 + 100

4S^2 = 100

Step 2 : Divide both sides by 4

4S^2/4 = 100/4

S^2 = 25

Step 3 : Take the square root

(squ root) S^2 = (squ root) 25

S = +/- (squ root) 25

Final answer ---> S = 5 OR S = -5
