hey where I sent I solved it in my notebook

Hello There! :)

Option B

A function must pass the Vertical line test. Draw a line. If it touches the graph more than once, it's a relation. If it touches the graph once, it's a function.

Hope this helps!

Answer:

Step-by-step explanation:

There are 3 possible scenarios

1) 5 questions from A and 3 questions from B:

2) 4 questions from each part:

3) 3 questions from A and 5 questions from B:

Total number of ways:

Answer:

Student has to do 8 questions such that he does at least 3 questions from both the sets

How can he go about (Set I, Set II)  =(3,5) or (4,4) or (5,3)

So, total number of ways of doing this is given by 

[tex]5c_{3} \times 7c_{5} + 5c_{4} \times 7c _{4} + 5c_{5} \times 7c _{3}[/tex]

[tex] = (10)(21) + (5)(35) + (1)(35) = 210 + 210 = 420[/tex]

Answer:

- 25

Step-by-step explanation:

The entire rectangle is 4 square units because the two triangles on the top put together makes the same shape as the square in the middle, which makes it 1 square unit. And the two bigger triangles on the bottom can create two squares if you break them apart and rearrange them again. So all of those shapes put together equals 4 square units.

Answer:

Area = 130 ft^2

Step-by-step explanation:

Area =length * width

Perimeter = 2(L + W)

L=3+x

W= x

Perimeter= 2(3+x+x) =2(3 +2x)=6+4x=46 so x=10

L=3 +10= 13

W= 10

Area = 13* 10 130

Angles are

No sean was wrong

Answer:

Sean is not correct. The answers are 100°, 35° and 45°.

Step-by-step explanation:

In my working, I labeled the part without a variable as a°.

Step 1: a° + 80° = 180° ( angles on a straight line sum up to 180° )

Step 2: a° = 180° - 80°. This is because 80 moves from the left side of the equation to the right side of the equation which affects it's sign( from + to -)

Step 3: a° = 100° . Subtract 80 from 180.

So we know that 100 is correct. Let's find the remaining angles.

Step 4: a° + ( x - 5 )° + ( x + 5 )° = 180° ( angles in a triangle sum up to 180°)

Step 5: 100° + x - 5° + x + 5° = 180°. Fix in the values of each variable correctly. Here we only know the value of variable a.

Step 6: (100° - 5° + 5°) + (x + x) = 180°. Group like terms to make calculations easier.

Step 7: 100° + 2x = 180°. -5+5 is the same as 5-5 which would give you 0. 0 + 100° is 100°.

Step 8: 2x = 180° - 100°. Move like terms to one side.

Step 9: 2x= 80°. Subtract 100° from 180° to get 80°

Step 10: 2x/2 = 80°/ 2. Divide both sides by 2.

Step 11: x= 40°. But this isn't the final answer. This is just the answer for all the x you see in the diagram. So fix in the values correctly.

Step 12: ( x-5° ). State it for your teacher to know which question you are given an answer to. From our calculations, we know that x = 40°.

Step 13: (40° - 5°)

Step 14: ( 35°). 40 minus 5 is 35.

Step 15: 35°. multiply the figure in the bracket by one. We can't leave our answer in the bracket.

Step 16: (x + 5). Using the same knowledge, fix in the values and do as the operation sign says.

Step 17: ( 40° + 5 °)

Step 18: (45°)

Step 19: 45 °

Step 20: Sean is not right because the angles in the triangle are 100°, 35° and 40°.

Answer:

  the properties of equality tell you so

Step-by-step explanation:

A couple of properties of equality come into play here:

Each of the properties of equality tells you an operation you can perform on an equation without changing the values of the variables that satisfy that equation.

If we start with the equation ...

  5c + 4p = 18.40

and we add 11.20 to both sides, we have not changed the values of the variables that satisfy this equation. This is the addition property of equality.

  (5c +4p) +11.20 = (18.40) +11.20

The substitution property of equality says I can substitute anything for its equal. The second given equation tells me that 2c +4p = 11.20. This means I can use 2c+4p wherever 11.20 might be found without changing any variable values. In the equation we got from addition, we can now make this substitution, and we have ...

  (5c +4p) +(2c +4p) = (18.40) +(11.20)

  7c +8p = 29.60 . . . . . . . collect terms

We obtained this equation using properties of equality that guarantee solutions to these equations are not altered by the process.

_____

*Additional comment

Technically, by doing the "collect terms" step, we have made the assumption that the values of c and p that satisfy the first equation are the same as the values of c and p that satisfy the second equation. This is usually the case we're interested in.

Answer:

  7.84 to 8.16 ounces

Step-by-step explanation:

The difference between the actual amount in the bottle and the target amount of 8 ounces can be at most 2% of 8 ounces. That amount is ...

  0.02×8 oz = 0.16 oz

The amount in the bottle can be this much higher:

  8 + 0.16 = 8.16 . . . ounces

or, it can be that much lower:

  8 - 0.16 = 7.84 . . . ounces

The range of values the bottle could contain is from 7.84 ounces to 8.16 ounces.

Answer:

249 + c

Step-by-step explanation:

The total of the 2 years is 249 from last year plus c from this year.

249 + c

Answer:

Y=mx+c

(4,2), (3,5)

answer is -3

Step-by-step explanation:

4=x1 and 2=y1

3=x2 and 5=y2

y2-y1/x2-x1

5-2/3-4

3/-1 or -3

since we are finding the slope,we have to minus the y2 from the y1 over the x2-x1 and we minus then simplify.

i believe the equation is -3x+4≤x-8

the answer would be x≥3

Answer:

f(x) = 8x

Step-by-step explanation:

The linear equation given in the form of a table is shown as:

[tex]\left[\begin{array}{ccc}x&f(x)\\3&24\\4&32\\5&40\\6&48\end{array}\right][/tex]

Because the equation is linear, in order to find the equation written in slope-intercept form, divide the rise (f(x)) by the run (x):

24 ÷ 3 = 8

32 ÷ 4 = 8

40 ÷ 5 = 8

48 ÷ 6 = 8

Because the quotient for each relation is 8, the linear equation can be written as f(x) = 8x.

-39 is the furthers away from 0

this is because if you draw a number line -16 would be 16 away from 0, 12 would be 12 away from zero and 7 would be 7 away from 0...

| - - - - - - - - - - - - - - - |- - - - - - | - - - - |

16 0 7 12

and -39 would be 39 digits away from 0, therefore its the furthest away from 0

Hope this helped you- have a good day bro cya)

Answer:

-39, or the absolute value of 39 is farthest from 0.

Step-by-step explanation:

-16 is 16 units from 0.

-39 is 39 units from 0.

7 is 7 units from 0.

12 is 12 units from 0.

39 > 16

39 > 7

39 > 12

Step-by-step explanation:

We observe two angles and the included side of ABC are congruent to two angles and the included side of DBE:

This is called ASA

Answer:

ASA postulate

Answer C is correct

Step-by-step explanation:

<ACB = < BED (Angle)

AC = DE (Side)

<CAB = < BED = 90° (Angle)

Therefore,

ABC triangle is congruent to DBE triangle according to ASA postulate.
