How do you solve this one 10x^2-25=x^2

solong [7]

10x^2 - 25 = x^2
Take the square root of each side.

$\sqrt{x^2} = \sqrt{10x^2 - 25}$
x = 10x - 5i

Identify the vertex of the function h(x) = −2x2 + 10x + 1.

Morgarella [4.7K]

The answer is vertex is (5/2, 27/2).

Find x= -b/2a where a=-2, b=10 then plug x value back into function to solve for y value of vertex (x,y).

Suppose you work for a large coffee distributor that has a secret coffee blend it sells to local stores. You mix the Gazebo blen

user100 [1]

Answer:

18lbs of Mexican Shade Grown coffee

Step-by-step explanation:

Since this is a ratio problem and we are given three values and one variable x (pounds of Mexican Shade Grown coffee needed) we can use the Rule of Three to solve this problem. In this rule we simply multiply the diagonal available values and divide by the third value to get the value of the variable, like so...

90lbs Gazebo <=====> 27lbs Mexican Blend

60lbs Gazebo <=====> x lbs Mexican Blend

(60 * 27) / 90 = x

1620 / 90 = x

18 lbs = x

We need 18lbs of Mexican Shade Grown coffee blend to mix with the 60lbs of Gazebo blend

Anyone know how to do this?

Lera25 [3.4K]

Answer:

Part A) 25

Part B) 225

Step-by-step explanation:

Part A

The slope of the graph gives us the mile per gallon of the car.

Recall that the slope of the graph is rise over run.

$m = \frac{200}{8} = 25$

Therefore car gets 25 miles per gallon

Part B) Since we know the slope of the direct variation line, we substitute into y=kx to get:

$y = 25x$

To find the number of miles the car travels using 9 gallons, we substitute x=9 to get:

$y = 25 \times 9$

This gives us 225 miles
