We graphically solve $f(x)=g(x)$ by graphing $f(x)$ and $g(x)$ and eyeballing the points where they intersect each other.

Really none of our choices are the solution set listing all the (x,y) pairs where the two functions meet because none of them is a set.

Anyway we count from the origin five to the right and three up to the meet of the lines, which is the point $(5,3)$ , last choice.

If p varies directly with T and p =105 when T=400.Find p when T =500

kumpel [21]

Answer:

Step-by-step explanation:

The variation p varies directly with T is written as

p = kT

where k is the constant of proportionality

To find p when T =500 we must first find the formula for the variation

That's

when p = 105 and T = 400

105 = 400k

Divide both sides by 400

So the formula for the variation is

when

T = 500

Substitute it into the above formula

That's

$p = \frac{21}{80} \times 500$

Simplify

The final answer is

What is the value of x?

solniwko [45]

Answer:

x = 7.5

Step-by-step explanation:

Since we see that sides AD and DC are equal, as well as sides BE and EC, we can use this information to conclude that the value of 2x-7 is equal to double the value of DE.

2x - 7 = 4(2)

2x - 7 = 8

2x - 7 + 7 = 8 + 7

2x = 15

x = 7.5
