Answer:
i think its B
Step-by-step explanation:
(-3,2)(1,2)...notice that the y values are the same.....when the y values are the same u have a horizontal line with a 0 slope.
IF the x values would have been the same (instead of the y values), then u would have had a vertical line with an undefined slope.
Answer:
w = 60
Step-by-step explanation:
the midsegment SU is half the measure of side RV , then
SU =
RV , so
w - 30 =
w ( multiply through by 2 to clear the fraction )
2w - 60 = w ( subtract w from both sides )
w - 60 = 0 ( add 60 to both sides )
w = 60
Answer:
See attached for a "Neat" quadratic formula.
a = -1
b = 2
c = 1
x = [-2 +- sqr root( 4 -4*-1*1)] / -2
x = [-2 +- sqr root( 4 -4*-1*1)] / -2
x = [-2 +- sqr root(8)] / -2
x1 = (-2 +2.8284271247) / -2
x1 = .8284271247 / -2
x1 = -0.41421
x2 = (-2 -2.8284271247) / -2
x2 = ( -4.8284271247) / -2
x2 = 2.4142135624
So the equation has the positive solution of
2.4142135624
Step-by-step explanation:
Marco needs to save a minimum of $420 more to buy a smartphone.
<u>Explanation:</u>
Cost of a smartphone = $495
Savings = $75
Least amount of money, m that needs to be saved = ?
Additional savings, m = Total - initial savings
m = $495 - $75
m = $420
The inequality equation would be 75 + m ≥ 495
Therefore, Marco needs to save a minimum of $420 more to buy a smartphone.
