Answer:

false and then true

Step-by-step explanation:

Hope this helps :)

Answer:

First one is False, second one is true.

Step-by-step explanation:

For the first one, the left side of the equation would equal -6/3, and the left side would be 3/-6. When simplified it would be: -2 = -1/2, which is incorrect.

For the second one, the left side and the right side are the same because either way you put it, they are still being multiplied, and the order doesn't matter. The end result will be -72 = -72, which is correct.

Answer:

5 five dollar and 7 one dollar

Step-by-step explanation:

let the number of one dollar be xthe number of five dollar be y

1x+5y=32

x+y=12

using elimination method

+x-x-y+5y-32+12=0

4y-20=0

4y=20

divide both side by 4

y=20/4 =5

so, if. y is 5 then x is

5y+x=32

5(5)+x=32

25+x=32

x=32-25

F(x) =?. Vertex is (2,-4) the other given point is (1,-2)

Answers

Given the vertex, (2, -4) as the minimum point, and that it is an upward-facing parabola that passes point (1, -2):

We could substitute these values into the vertex form of the quadratic function,

f(x) = a(x - h)^2 + k

where:

(h,k) is the vertex

The axis of symmetry is the vertical line x = 2

The value of “a” determines whether the graph opens up or down, and makes the parent function wider or narrower.

The value of “h” determines how far left or right the parent function is translated.

The value of “k” determines how far up or down the parent function is translated.


Now that we’ve established these definitions, we can substitute the given values into the vertex form:

f(x) = a(x - 2)^2 - 4

In order to determine the value of “a”, we must substitute the values of the other given point, (1, -2) into the equation:

f(x) = a(x - 2)^2 - 4

-2 = a(1 - 2)^2 - 4

-2 = a(-1)^2 - 4
-2 = a - 4

Add 4 to both sides to solve for “a”

-2 + 4 = a - 4 + 4
2 = a

Now that we have the value of a = 2, we can establish our quadratic function in vertex form:

f(x) = 2(x - 2)^2 - 4


I’m also including a screenshot of the graph of the function we came up with.

help asap plsssssssssssssssssssssssssss. Find the missing parts of each number line. Assume that the lines have been split into equal parts.

Answers

Answer:

16 for the first one. each segment is 4

40 for the second. each segment is 8

Answer:

0, 4, 8, 12, 16

8, 16, 24, 32, 40, 48

Step-by-step explanation:

The first number line has 6 parts. 24÷6=4. Each vertical line will increase by 4.

So starting at 0, the parts of the number line are:

0, 4, 8, 12, 16, 20, 24

The specific part being asked for is 0, 4, 8, 12, 16

The second number line has 8 parts. 64÷8=8. Each vertical line will increase by 8.

Starting at 0, the parts of the number line are:

0, 8, 16, 24, 32, 40, 48, 56, 64

The specific part being asked for is 8, 16, 24, 32, 40, 48

Which equation matches the graph of the greatest integer function given
below?

Answers

Answer:  

D. y = [x] - 2

Explanation:  

The Greatest Integer Function is denoted by y = [x].

     For all real numbers, x, the greatest integer function returns the largest integer less than or equal to x. In essence, it rounds down a real number to the nearest lowest integer.

         In the plot of y = [x], the plot starts from origin because y = [0] = 0.

                      But, in the question, all the lines are shifted 2 units downward, as it starts from (0, -2).

i.e for every values of x, y moves two units down

                               So our answer is y = [x] - 2.

(Information reworded from "InesWalston" who is another user on Brainly when they responded to the same question!)

                             Hope this helps, good luck! :D

Answers

Answer:

The speed of the boat in still water is 12 miles per hour, while the speed of the current is 9 miles per hour.

Step-by-step explanation:

We'll use x as the speed of the boat in still water in miles per hour.

We'll use y as the speed of the current in miles per hour.

When the boat is traveling downstream, the speed of the boat is helped by the speed of the current and the net speed is x + y.

When the boat is traveling upstream, the current opposes the movement of the boat, and the net speed is x - y.  

Using a table where d = distance in miles, r = rate or speed in miles per hour, and t = time in hours can help figure out how to figure out this problem.

─────────────────

Downstream│210│(x + y)│10

Upstream│210│(x - y)│70

─────────────────

Recall that distance = rate x time or d = rt.

210 = (x + y)10 ➤ Equation from downstream information.

210 = (x - y)70 ➤ Equation from downstream information.

210 = 10x + 10y ➤ Distribute.

210 = 70x - 70y ➤ Distribute.

7 × 210 = 7 × 10x + 7 × 10y ➤ Multiply the 1st equation by 7.

1470 = 70x + 70y ➤ Add the 1st equation to the 2nd.

210 =70x - 70y ➤ Add the 1st equation to the 2nd.

1680 = 140x

─────────────────

1680/140 = 140x/140

x = 12

210 = (12 + y)10 ➤ Substitute x = 12 into one of the original  equations to find y.

210 = 120 + 10y

-120 - 120

90 = 10y

90/10 = 10y/10

y = 9

Find the slope and y-intercept for this table.​

Answers

Answer:

Slope is -5 and y-intercept is 90.

Step-by-step explanation:

Use the two values that you circles (4, 70) and (6, 60) .

slope (m) = the change in y-value/ (the change in the x-values).

m = (70 - 60)/(4 - 6) = 10/-2  = -5

The y-intercept is the value of "b" in the equation y = mx + b.

 Using  y = mx + b,  substitute the value m and use point of your points (4, 70).

   y = mx + b

   70 = -5(4) + b     Now solve for "b".

  70 = -20 + b

 +20 = +20      

   90 = b

Can Defects A company that makes soda pop cans finds that the

probability of producing a can without a puncture is 0.96, the probability that

a can does not have a smashed edge is 0.93, and the probability that a can

does not have a puncture and does not have a smashed edge is 0.893.

(a) Are the events "selecting a can without a puncture" and "selecting a can

without a smashed edge" mutually exclusive? Explain.

(b) If a quality inspector randomly selects a can, find the probability that the

can does not have a puncture or does not have a smashed edge

Answers

Using probability concepts, it is found that:

a) Since [tex]P(A)P(B) \neq 0[/tex], the events are not mutually exclusive.

b) 0.997 = 99.7% probability that the  can does not have a puncture or does not have a smashed edge.

Item a:

Two events, A and B, are mutually exclusive if:

[tex]P(A \cap B) = 0[/tex]

In this problem:

Event A: No puncture, thus, [tex]P(A) = 0.96[/tex].Event B: No smashed edges, thus [tex]P(B) = 0.93[/tex]

The problem also states that the probability of neither is [tex]P(A \cap B) = 0.893[/tex].

Since [tex]P(A)P(B) \neq 0[/tex], the events are not mutually exclusive.

Item b:

Using Venn probabilities, the "or" probability is given by:

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

With the given values:

[tex]P(A \cup B) = 0.96 + 0.93 - 0.893 = 0.997[/tex]

0.997 = 99.7% probability that the  can does not have a puncture or does not have a smashed edge.

4a: 4a wants you to find how many tickets you can buy for  130$. So first replace the y or c(x) with 130 x, which gives 130=17x-10. Now we find x, first add 10 to both sides to cancel the -10, 140=17x, then divide 17 from both sides which gives 8.235, so we can buy 8 tickets.
