Find the value of x when y=70

Answers

Answer:

Direct proportionality

If the value of y varies directly with x, the value of x when y=70 is 20.

Given that, the value of y varies directly with x.

What is a proportional relationship?

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".

We know that, the value of y varies directly with x

y ∝ x

⇒ y = kx

⇒ k = y/x

⇒ k = 21/6

⇒ k = 7/2

So, k = y/x

7/2 = 70/x

⇒ 1/2 = 10/x

⇒ x = 20

Therefore, if the value of y varies directly with x, the value of x when y=70 is 20.

What is the equation of the line that passes through the point (5,6) and has a slope of 2 ?

Answers

Answer:

y = 2x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2, thus

y = 2x + c ← is the partial equation

To find c substitute (5, 6) into the partial equation

6 = 10 + c ⇒ c = 6 - 10 = - 4

y = 2x - 4 ← equation of line

Cole went to the store and bought pants and shirts. He bought a total of 12 items and paid $234. If Pants cost $22 and Shirts cost $16, how many of each did he buy?

Select two equations that could be used to determine the number of pants (p) and shirts (s) Cole purchased

Answers

Answer:

Cole bought 7 pants and 9 shirts.

Step-by-step explanation:

Let p represent the number of pants and s represent the number of shirts.

Then using the provided data two equations can be formed.

p + s = 12...(i)

22p + 16s = 234...(ii)

Solve (i) and (ii) simultaneously.

Multiply (i) by 16 and subtract the resultant equation from (ii) as follows:

16p + 16s = 192

-22p - 16s = -234

-6p = -42

p = 7

Substitute p = 7 in (i) and solve for s as follows:

p + s = 16

7 + s = 16

s = 9

Thus, Cole bought 7 pants and 9 shirts.
