Answer:

x is mL of 25% acid and y is mL of 50% acid

We set up 2 equations:

A) x + y = 250

B) .25 x + .50y = .35 * 250 which equals

B) .25x + .50y = 87.50  Multiplying A) by -.5

A) -.5x -.5y = -125  adding the equations we get

-.25x = -37.50

x = 150 mL

y = 100 mL

Which equation describes the graphed function?
Oxana [17]

Using translations, it is found that the equation the represents the graphed function is:

y = -f(x) - 3, given by option C.

----------------------------------

  • The parent function is f(x) = \sqrt{x}.
  • <u>As x increases, it's value increases. In the graph, as x increases, it decreases</u>, thus it was multiplied by -1, that is, -f(x).
  • The parent function is defined for x \geq 0, and the same is valid for the function in the graph, thus we have f(x) and not f(-x).
  • The initial value of the parent function is y = 0, here it is y = -3, thus it was shifted down 3 units, that is, y = -f(x) - 3, and the correct option is C.

bulgar [2K]

Answer:

a) 101.125 gallons.

b) 3312 miles.


Step-by-step explanation:

You know that Jane​'s car will go 420 miles on 17.5 gallons of gasoline in highway driving, therefore:

a) You can calculate the number of gallons  it will take to drive 2427 miles from her house to a​ friend's house as following:

\frac{420miles}{17.5gallons}=\frac{2427miles}{x}\\x=101.125gallons

b) You can calculate the distance  the car can be driven on 138 gallons of​ gasoline as shown below:

\frac{420miles}{17.5gallons}=\frac{y}{138gallons}\\y=3312miles
