Answer:
-2x² + 90x + 500
Step-by-step explanation:
Use FOIL method
Area of rectangle = length * width
= (50 - x)(2x + 10)
= 50*(2x) + 50*10 + (-x)*2x + (-x)*10
= 100x + 500 - 2x² - 10x
= -2x² + 10<u>0x - 10x </u>+ 500 {Combine like terms}
= -2x² + 90x + 500
Answer:
linear function, growth factor of 4
Step-by-step explanation:
The graph has the shape of a straight line, so it is linear.
The graph starts at point (0, 0). It passes through point (1, 4).
slope = (y2 - y1)/(x2 - x1) = (4 - 0)/(1 - 0) = 4/1 = 4
The slope is 4. Growth factor is the same as slope for a linear function.
Answer:
<span>2y=3x-7
y = 3/2x - 7/2
y = 1.5x - 3.5 so slope = 1.5
</span><span>line parallel so it has same slope = 1.5
</span>
y +1 = 1.5(x - 0.5)
y + 1 = 1.5x - 0.75
y = 1.5x - 1.75
answer: equation y = 1.5x - 1.75

Actually Welcome to the concept of logarithms.
Since here the log is on both sides, we take antilog on both sides, so we get as,
==> 2-x = -5x - 18
==> -x + 5x = -18 -2
==> 4x = -20
==> x = -20/4
==> x = -5
hence, x = -5
Answer:
15. 1/4 16.1/8 17. 1/3 18./1/5
Step-by-step explanation:
how many times it is EQUALLY DIVIDED so if its split into fours like #15 then its 1/4 or 16 EQUAL PARTS 1/16
