Answer:
Step-by-step explanation:
5a/9 - 21/2 - 11a/9 = -11/3
18(-6a/9 - 21/2 = -11/3)
-12a - 189 = -66
-12a = 123
a = -123/12
a = -41/4
answer is A

The car's rate in miles per minute is 1.55 miles.
The car will travel 23.25 miles in 15 minutes.
What is Speed- Distance Formula?
- Speed = Distance/Time
- Distance = Speed X Time
- Time = Distance / Speed
Given:
A car is traveling at a rate of 93 miles per hour.
In 60 minutes the car travel = 93 miles
So, In oneminutes the car travels = 93 /60
= 1.55 miles
and, In 15 minutes the car travel = 1.55 x 15
= 23.25miles

Answer: The car is going 1.55 miles per minute.
Step-by-step explanation: Since there are 60 minutes in an hour, and the car is going 93 mph, you would simply divide 93 by 60.

Step-by-step explanation:
B. f(x) = x3 + x2 − x − 1
C. f(x) = x3 + 3x2 − 4x − 12
D. f(x) = x3 + 2x2 − 2x − 1
Answers
Answer:
B. f(x)=x³+x²-x-1
Step-by-step explanation:
The value of the graph f(x) shows that at x=1 and x=-1 must yield f(x)=0
which is true in case B.
A. f(1)=1+1-4-4= -6≠0
C. f(1)= 1+3-4-12=-12≠0
D. f(-1)= -1+2+2-1= 2≠0
Hence, option B is correct
i.e. f(x)= x³+x²-x-1

There are two kinds of solving but elimination seems best for this system:
-2x-9y=-25
4x+9y=23 (multiplied it by -1 so you can eliminate the variable "Y")
---------------
2x=-2
x=-1 (divide by 2 on each side)
-2(-1)-9y=-25 (insert what you received for what "X" is)
2-9y=-25 (simplify)
-9y=-27 (subtract 2 on each side)
y=3 (divide each side by -9)
(-2/9)x+25/9 and (-4/9)x+23/9.
Then equate them to each other
(-2/9)x+25/9=(-4/9)x+23/9
Then solve of x
(-2/9)x+(4/9)x = (23/9) - (25/9)
X = -1
Then plug in X and solve for y
Y = (-2/9)(-1) + (25/9)
Y= (27/9)
Y= 3
So your solution is (-1,3)

y = x - 7....the slope here is 1. A parallel line will have the same slope.
y = mx + b
slope(m) = 1
(1,0)...x = 1 and y = 0
now we sub and solve for b, the y int
0 = 1(1) + b
0 = 1 + b
-1 = b
so ur parallel line is : y = x - 1
We know that a parallel line has the same slope. And the slope-intercept form in y=mx+b.
1. simplify x-y=7 to isolate y.
subtract x: -y=-x+7
then divide by -1: y=x-7
so the slope is 1 (m=1)
2. plug in m=1 and (1,0) *******alternate solution below
0=1(1)+b
0=1+b subtract 1
-1=b (b=-1)
3. y=mx+b plug in numbers. ( in bold)
y=1x-1
your answer is y=x-1
*****alternate answer solution from step 2 (using step 1)
2. use the formula y-y1=m(x-x1) (y1 and x1 is with the 1 below the letters BTW)
plug in (1,0)
y-0=1(x-1)
y=1x-1
y=x-1 is your answer.
So it comes out as the same answer. Just 2 different ways to doing it! :)
