Answer:
280,000
Step-by-step explanation:
10^5=100,000
2.8 x 100,000=280,000
If this is algebra, then you will be using a parabola to solve this problem:
t=-b/2a
t=-8/2(-16) = 8/-32 = -1/4
t=-1/4=-0.25
h=-16(0.0625)+8(-0.25)+80
h=1-2+80
h=79
(-0.25,79)
then plug this ordered pair above and draw a line directly down the middle of it to use as a "mirror" and plug 2 different numbers(preferably 0 and 1) into the variable t to find the other two points and then reflect the two points over the "mirror" to get the last two points to graph your paprabola
Answer:
Because +- or - + = -
Step-by-step explanation:
-a + b = - c
a + - b = - c
-a × b = - c
a × - b = -c
Extra references:
-ve ×/+ -ve = +ve
+ve ×/+ -ve = - ve
-ve ×/+ +ve = - ve
+ve ×/+ +ve = +ve
Hope these could solve your problem.
Answer:
the y value equals 5
Step-by-step explanation:
(x,y)so
plug in 8 for x
5(8)=40
40 -2y=30
subtract 40 from both sides
-2y=-10
divide by -2
y=5
