Answer:

The answer is option A

Step-by-step explanation:

Equation of a line is y = mx + b

where

m is the slope

b is the y intercept

From the question

b / y intercept = 3

m / slope = 1

Substitute these values into the below equation

y = mx + b

We have the answer as

y = x + 3

Hope this helps you

Answer: A. Y= x+3

Step-by-step explanation: since the value of the slope is 1 it would go next to the x but x is also equal to 1x. And you add 3 since the y intercept is 3 and the format of the equation is y equals slope plus the y intercept hope this helps

If the cost, C(x), for manufacturing x units of a certain product is given by
Diano4ka-milaya [45]

Answer:

99 units.

Step-by-step explanation:

The cost function for manufacturing <em>x</em> units of a certain product is:

C(x)=x^2-15x+34

We want to find the number of units manufactured at a cost of $8350. Therefore:

8350=x^2-15x+34

Subtract 8350 from both sides:

x^2-15x-8316=0

This equation can be a bit difficult to factor, if even possible, so we can use the quadratic formula:

\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

In this case, a = 1, b = -15, and c = -8316. Thus:

\displaystyle x=\frac{-(-15)\pm\sqrt{(-15)^2-4(1)(-8316)}}{2(1)}

Simplify:

\displaystyle x=\frac{15\pm\sqrt{33489}}{2}

Evaluate:

\displaystyle x=\frac{15\pm183}{2}

Therefore, our solutions are:

\displaystyle x=\frac{15+183}{2}=99\text{ and } x=\frac{15-183}{2}=-84

We cannot produce negative items, so we can ignore the second answer.

Therefore, for a cost of $8350, 99 items are being produced.

Nikitich [7]
The first poster is not an accurate representation of the painting, but the second poster is an accurate representation because the ratio between the first and original lengths did not equal the ratio between the first and original widths but the second poster's ratios were equal.
