Answer:

<em>The cost in dollars and the amount of yogurt are proportional</em>

Step-by-step explanation:

<u>Proportions</u>

Two variables are proportional if the ratio or division between them is a constant value.

Kareem buys a 32-oz container of yogurt for $2.56. We can compute the ratio of the quantity of yogurt and price 32/2.56 and we get 12.5. Jonah buys a 6-oz container of yogurt for $0.48. The relation is now 6/0.48=12.5

Since both ratios are equal, we can say the amount of yogurt, and the cost in dollars are proportional variables

What are the solutions to the quadratic equation below?
Luden [163]

Using factorization method;

x²+13x+40=0

x²+13+40

Find two numbers that you can add together to give the co-efficient of variable x. (I.e 13 for this question). Also, you'll find two numbers that you can multiply with each other to give you the whole number as an answer. (I.e 40 in this question). The two numbers must be the same (i.e the two numbers that will be added to give the co-efficient of x and the two numbers that will be multiplied to give the whole number must be the same two).

The two numbers are +5 and +8

The equation will therefore be = x²+5x+8x+40

You'll then factorize (I.e use a common factor of both values to bracket them)

x(x+5)+8(x+5)

(x+8)(x+5)

x is therefore (x+8=0) or (x+5=0)

x=(x=0-8) or (x=0-5)

x= -8 or x= -5

Please help :(<br> if you can please also give a explanation. thanks
aliina [53]

Answer:

x = 20

Step-by-step explanation:

since the triangle is a right angle, that means the angle is 90 degrees

equation:

30 + 3x = 90

subtract 30 on both sides

30 - 30 + 3x = 90 - 30

3x = 60

then divide each side by 3

\frac{3x}{3} = \frac{60}{3}

x = 20

2.) 5x+3y=12 --> y= -5/3x + 4

3.) x-y=1 --> y= x- 1

4.) x-3y=-15 --> y=1/3x + 5

5.) 8x-10y=20 --> y=4/5x - 2

6.) 14x+6y=36 --> y=-7/3x+6

Step-by-step explanation:

Hope this helped.
