Step-by-step explanation:
Answer: there you go
Step-by-step explanation:
Answer:
16)
17) y = -x - 4
18) y = -2x - 1
19) y = -2x
20)
Step-by-step explanation:
With the two points you find the slope using
Then using that slope, plug the slope in with one of the points values of x and y into the point slope formula, and smiplify that into the y-intercept formula.
Answer:
a) f(x) = 6x^2 - 4x
b) 80 ft²
Step-by-step explanation:
Refer to attached for full question
a.
<u>Area formula for rectangle:</u>
We see the width of the white part of the banner is 3x - 2 and height is 2x
<u>Function to define the area</u>
- f(x) = (3x - 2)*2x = 6x^2 - 4x
b.
<u>If maximum width of white area is 10 ft, then the dimensions are:</u>
- 3x - 2 = 10 ⇒ 3x = 12 ⇒ x = 4
- w = 10, h = 2*4 = 8
- A= 10*8 = 80 ft²
The GCF of 16 and 40 is 8.
16/8 = 2
40/8 = 5
We can rewrite this using the distribute property like so:
<h3><u>8(2 + 5)</u></h3>
Using the distributive property:
16 + 40
16 + 40 = 56
We can also add inside the parentheses and multiply and we'll get the same answer.
8(7)
56
