Answer:
6.6
Step-by-step explanation:
For this problem, you need to add 5 to the given equation, by replacing "c" with "5"
1.8(5)-2.4
= 6.6
X=2 so the value of x+5 is 7
Answer:
y² = 36x
Step-by-step explanation:
Parabola opens right.
Thus equation is from; y² = 4ax
And focus is at (a, 0)
Since we are given focus at (9, 0),it implies that a = 9
Thus, equation of parabola is;
y² = 4 × 9 × x
y² = 36x
We have that
y = 2x + 8
for x=1-----------> y=2*1+8=10
for x=2-----------> y=2*2+8=12
for x=3-----------> y=2*3+8=14
.
.
.
the equation y = 2x + 8 ----------- > defines y as a function of x, because <span>for each x there is only one value of y</span>.
the answer is
yes, the equation y = 2x + 8 defines y as a function of x
Answer:
Step-by-step explanation:
After some number of minutes m, Mohammed's altitude will be ...
40 +10m
and Dana's altitude will be ...
165 -15m
The altitudes will be the same when ...
40 +10m = 165 -15m
25m = 125 . . . . . . . . . . . add 15m-40
m = 5 . . . . . . . . . . . . . . . divide by 25
The height of the two balloons after 5 minutes will be 40+10·5 = 90 ft.
