kobusy [5.1K]
Answer : 76


Step by Step Explanation:

Substitute for "r" and solve for "t":
5(4t+8) + 2t = 414
22t + 40 = 414
22t = 374
t = 17 (# of tulips sold)
---
r = 4*17+8 = 76 (# of roses sold)

Find two numbers whose difference is 150 and whose product is a minimum. step 1 if two numbers have a difference of 150, and one
valentinak56 [21]
The lowest possible product would be -5625 given the numbers 75 and -75. 

We can find this by setting the first number as x + 150, which we see in the equation given above. The other number would have to be simply x since it has to have a 150 difference. 

Next we'll multiply the numbers together. 

x(x+150)
x^2 + 150x

Now we want to minimize this as much as possible, so we'll find the vertex of this quadratic graph. You can do this by finding the x value as -b/2a, where b is the number attached to x and a is the number attached to x^2

-b/2a = -150/2(1) = -150/2 = -75

So we know one of the values is -75. We can plug that into the equation to find the second. 

x + 150 
-75 + 150 
75

What is the equation of the line that is parallel to the line y =1/3 x + 4 and passes through the point (6, 5)?
lianna [129]

Answer:

y = \frac{1}{3} x + 3

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 )

y = \frac{1}{3} x + 4 ← is in slope- intercept form

with slope m = \frac{1}{3}

Parallel lines have equal slopes , then

y = \frac{1}{3} x + c ← is the partial equation

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

5 = 2 + c ⇒ c = 5 - 2 = 3

y = \frac{1}{3} x + 3 ← equation of parallel line
