Step-by-step explanation:
Answer:
x= -10 , x= -5 , x=5
Step-by-step explanation:
we are given function as
x^3+10x^2-25x-250
We are given one of zero is x=-10
we can find all possible factors of 250
so, we will check zeros at x=-5 and x=5
At x=-5:
we can plug x=-5
At x=5:
we can plug x=5
So, other zeros are
x=-5 and x=5
All zeros are
x=-10 , x=-5 , x=5
1. a) .05
b) 10
c) .5
d) 50
2. 0.5÷10= 0.05
4. a) 2
b) 0.02×10= .2
5. a) 2÷10= .2
b) 0.2÷10= .02
Answer:
208 mi
Step-by-step explanation:
If David rents the car for four days, that's an up-front cost
of 4 × 23.95 = $95.80.
The other cost depends on the distance (d) he drives.
The equation for his total cost (C) is
C = 0.26d + 95.80
If David has a budget of $150, then
150 = 0.26d + 95.80
Subtract 95.80 from each side
54.20 = 0.26d
Divide each side by 0.26
d = 208.5 mi
David can't drive that extra 0.5 mi without going over his budget.
He can drive 208 whole miles.
Answer:
Q1. (a) (i) p = -9, q = 11
Q3. (a) Line 1: x = 0.5
Line 2: x = -2
Q3. (b) (i) (ii) For both lines, they will be perpendicular to the x-axis and they will pass their respective x-coordinates of 1 and -2 1/2.
Step-by-step explanation:
Q1. (a) (i) 5(-5) - 3p = 2
-25 - 3p = 2
3p = -25 - 2
p = -27/3
p = -9
5(7) - 3q = 2
35 - 3q = 2
3q = 35 - 2
3q = 33
q = 11
Q3. (a) Since all points on Line 1 have x-coordinates of 0.5, we can conclude that the equation is x = 0.5. Same goes for Line 2, of which all points have x-coordinates of -2 instead, making the equation x = -2.
Hope this helped!
