Who can help me with these quick problems?

Answer:

We have to use the formule to calculate the vertex which is: V(-b/2a;4ac-b^2/4a)

A) y=x+7 where a=1 b=0 and c=7

By replacing we have: V(0;28/4) V(0;7)

B) y=-x where a=-1 b and c=0 so V(0,0)

Answer:

21,850

Step-by-step explanation:

850 x 5 = 4,250

17,600 + 4250 = 21,850

Answer:

22,815

Step-by-step explanation:

35% of 35,100 is 12285, then you subtract that from 35,100 to get 22,815. Hope this helps.

Answer:

60 degrees

Step-by-step explanation:

A triangle is 180 degrees and there is already 40 and 80 degrees.

So... 180-80-40=60 degrees.

Answer:

# yellow = 20

# blue = 23

# red = 5

Step-by-step explanation:

let 'r' = # red marbles

let '4r' = # yellow marbles

let '3+4r' = # blue marbles

r + 4r + 3 + 4r = 48

9r + 3 = 48

9r = 45

r = 5

red = 5

yellow = 4(5) = 20

blue = 3+4(5) = 23

3x +39 =90

3x =90-39

3x=51

make it in fraction

3x over 3 equals to 51 over 3

simplify

= 51

Answer:

x = 17

Step-by-step explanation:

a straight line equals 180º so each side is 90º.

90 - 39 = 51

3 x __ = 51

3 x 17 = 51

so..x = 17

Answer:

x= -1.118

Step-by-step explanation:

Firstly you need to start with the bracket

-5(5x +5) + 3(5x +3)

=( -25x +25) + (15x +9)

= -25x +25 +15x +9= -4x -6x

secondly you join the like terms together

25+9= -4x -6x +25x -15x

34= -38x

-38x ÷ 34

x= -1.118

Answer:

Step-by-step explanation:

2. (-2-1)/(1-0)= -3/1 = -3

3. (6-5)/(3-2)= 1/1= 1

4. (1-1)/(-6-6)= 0/-12= 0

6. (-2-2)/(5-5)= -4/0 = undefined

5. (8-6)/(4-4)= 2/0 = undefined

7. (-5-5)/(-3-2)= -10/-5= 2

8. (-8-8)/(7-9)= -16/-2= 8

9. (1+8)/(-8+5)= 9/-3= -3

10. (7-10)/(-3+3)= -3/0= undefined

11. (17-18)/(18-17)= -1/1= -1

12. (1+4)/(4+6)= 5/10 = 1/2

13.(4-0)/(-2-10)= 4/-12 = -1/3

14. (-2+1)/(-8-2)= -1/-10= 1/10

15. (-2+9)/(3-5)= 7/-2= -7/2

16. (-5-6)/(3-12)= -11/-9= 11/9

Add 4 minutes to the 24 minutes each day. Multiply the number of minutes by the time.

Answer:

1) 1/2

2) 2/1

3) -1/2

4) -2/1

Step-by-step explanation:

use two ordered pairs to find slope by using this formula:

difference of y-values over difference of x-values

example:  for problem #1, I used points (0,3) and (2,4)

difference of y-values:  4-3 = 1

difference of x-values:  2-0 = 2

Slope is 1/2

Answer:

  17) x = 10√2

  18) x = 4√6

Step-by-step explanation:

These problems rely on your knowledge of the side ratios of special triangles

  45°-45°-90° triangle: 1 : 1 : √2

  30°-60°-90° triangle: 1 : √3 : 2

__

17) 5 is the short side of the isosceles right triangle, so its hypotenuse is 5√2. That length is the shortest side of the 30/60/90 triangle, so its longest side is 2 times that:

  x = 10√2

__

18) 8 is the longest side of the 30/60/90 triangle, so its long leg will be 8(√3)/2 = 4√3. The hypotenuse of the isosceles right triangle is √2 times that, so ...

  x = (4√3)(√2)

  x = 4√6

Answer: 20.1

​  

\sin 85=\frac{20}{x}

sin85=

​  

x\sin 85=20

xsin85=20

Cross multiply.

\frac{x\sin 85}{\sin 85}=\frac{20}{\sin 85}

Divide each side by sin 85.

Answer:

No Solutions

Step-by-step explanation:

The two points are (3,2) and (-2,-2)

Slope is y change over x change.

So... -2-2 over -2-3 equals to -3-(-2) over -2-(-2).

That is -3+2 over -2+2 which is -2 over 0.

You can't divide by zero so the slope is "NoSolutions"

Answer: 3

Step-by-step explanation:

Vince will have to buy three cartons of 500 ml each.

An expression in mathematics is a combination of terms both constants and variables.

Given is that every time Vince orders Chinese food, he gets egg drop soup. So, he decides to learn how to make it himself. His recipe calls for 1.5 liters of broth, but he can only find 500 milliliter cartons at the store.

We know that -

1 Liter = 1000 milliliters

1.5 liter = 1500 liters

Now -

1 carton 500 ml.

Then, 1 ml will be in (1/500) carton.

So, 1500 ml will be in (1/500 x 1500) = 3 cartons

Therefore, Vince will have to buy three cartons of 500 ml each.
