a system with no solutions

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

Answer:

Step-by-step explanation:

850 x 5 = 4,250

Answer:

Step-by-step explanation:

a solution is where both of the lines meet.  or they have the same point on each line. so you can set the equation of each line equal to the other.

for this  "solution" just look at the graph and see where the two lines meet.. and find the x coordinate of that point.

I see it meeting at x =2     get it?

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:

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:

35

Step-by-step explanation:

This is a combination problem therefore we need to use the combination formula using factorials, plug in the values for n and r which would be 7 since there are 7 individuals in the group and 3 because we are making outcomes of 3.

C(n,r)=C(7,3)

=7!(3!(7−3)!)

=7!3!×4!

= 35

Finally, we can see that the total number of possible outcomes is 35

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:

If y = 2x - 5, and x = 3z, then y = 6z - 5

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: 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.
