Just isolate the variable x.
x*5+3=2
5x=-1
x=-1/5
Answer:
<u>Options 3, 4 and 5</u>
Step-by-step explanation:
Given:
F(x) = x³ + 3x² - 25x - 75
Factor the given function:
F(x) = x³ + 3x² - 25x - 75
⇒ take x² a common from (x³ + 3x²) and (-25) a common from (- 25x - 75)
F(x) = x²(x+3) - 25 (x+3)
⇒ take (x+3) as a common
F(x) = (x+3) (x² - 25)
(x² - 25) = (x-5) (x+5)
∴ F(x) = (x+3) (x-5) (x+5)
<u>The answer are options 3, 4 and 5</u>
Hmmm i want to say 12 because it says "each dollar he spends on a candy bar:
Answer:
y = 1/5x + 2 1/5
Step-by-step explanation:
first find the negative reciprocal slope of 5x + y = 30 because perpendicular lines have negative reciprocal slope:
=> y = -5x + 30, negative reciprocal of the slope -5 is 1/5
substitute the new slope 1/5 and the coordinate (9, 4) into the equation: y = mx + b to solve for b
=> 4 = 1/5(9) + b
=> 4 = 9/5 + b
=> b = 2 1/5
plug in the slope 1/5 and b = 2 1/5 into the equation: y = mx + b
=> y = 1/5x + 2 1/5
Answer:
2 / 5
Step-by-step explanation:
Fractions are written in the form part/whole, in this case, the part is 18 and the whole is 45 so the fraction would be 18 / 45 which simplifies to 2 / 5.
