Answer:

i hope this is what you are looking for

Step-by-step explanation:

liz is 36

rylan is 75

36*2 is 72

72+3 is 75

y= x (rylan's age)-3 /2

75-3=72

72/2

36

Ms Harris has a taco stand. She has found that her daily costs are approximated by the following equation:
mrs_skeptik [129]
<span>a. find the number of units of tacos she must sell to minimise her cost.
</span>to find a minimum we need to find the function derivative and make it equal to zero:
dc/dx = 2x - 40 = 0
2x = 40
x = 20
therefore to minimize the cost, she needs to sell 20 units of tacos

<span>b. find the minimum cost.
</span>that can be done by substituting the previous result, 20 tacos, in the original equation:
<span>C(x) = x^2 - 40x + 610
</span>C(20) = (20)^2 - 40(20) + <span>610
</span>= 400 - 800 + 610
= 210
the minimum cost will be 210 dollars

To find the slope, you use the slope formula (m):

m=\frac{y_2-y_1}{x_2-x_1}    and plug in the two points

(-3, 4) = (x₁, y₁)

(2, -1) = (x₂, y₂)

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{-1-4}{2-(-3)}       [two negatives cancel each other out and become positive]

m=\frac{-1-4}{2+3}

m=\frac{-5}{5}

m = -1        The slope is -1

Maybe it’s y=1x-2. I hope this helps since we have no clue what the x is in the question we just assume it’s own

Determine the value of a if one solution to the quadratic equation is x equals 5 + 3/2 I
Sindrei [870]

The value of a is \frac{-9}{4}

Step-by-step explanation:

<u>1. Determine the other solution of x</u>

If one value is 5 + \frac{3}{2} then the other value is 5 - \frac{3}{2}

<u>2. Use reverse technique to find the equation</u>

(5 + \frac{3}{2}) (5 - \frac{3}{2}) = 0

25 - \frac{-15}{2} + \frac{15}{2} - \frac{9x^{2} }{4} = 0

- \frac{9x^{2} }{4} + 25 = 0

<u>3. The equation is</u> - \frac{9x^{2} }{4} + 25 = 0

<u>4. Find the value of a</u>

a is the number with the variable x^{2} therefore it is - \frac{9}{4}
