Answer:
y = mx + b
Since it is perpendicular to the given line, its slope is the negative reciprocal of the slope of the given line.
Slope of given line:
m0 = -a/b = -(-3) / (1) = 3
Slope of perpendicular line:
m = -1/3
y = (-1/3)x + b
Use the given point to find b.
2 = (-1/3)(3) + b
2 = -1 + b
b = 3
y = (-1/3)x + 3

Answer:
7/13
Step-by-step explanation:
To find the probability that it is not white
P( not white) = number of balls that are not white / total balls
The balls that are not white are red and green = 4+3
= (4+3)/ ( 4+6+3)
= 7/13
Answer:
x = 17 $20 bills
y = 30 $5 bills
General Formulas and Concepts:
- Order of Operations: BPEMDAS
- Multivariable Systems
Step-by-step explanation:
<u>Step 1: Define variables</u>
x = # of $20 bills
y = # of $5 bills
<u>Step 2: Set up systems of equations</u>
<u /><u />
<u />
<u>Step 3: Solve for </u><em><u>x</u></em>
- Rewrite:
- Substitute:
- Distribute 5:
- Combine like terms:
- Subtract 235 on both sides:
- Divide both sides by 15:
By solving for <em>x</em>, we now know that we have 17 $20 bills.
<u>Step 4: Solve for </u><em><u>y</u></em>
- Define: x + y = 47
- Substitute: 17 + y = 47
- Subtract 17 on both sides: y = 30
Now we know that we have 30 $5 bills.
Answer:
The correct option is C
Step-by-step explanation:
(x^3 +12x^2 +38x +26) / (x+4)
Use the coefficients of dividend.
And the divisor is -4:
Bring down 1 and multiply it by -4 and add to 12
12-4 = 8
Now multiply 8 by -4 = -32
48-32 = 6
Now multiply 6 by -4 = -24
26-24= R2
1 12 38 26
-4 -32 -24
_______________
1 8 6 R2
Thus the correct option is C ....
C’s the answer I’m pretty sure
