Step-by-step explanation:
They washed a total of 96 cars during both car washes. How many cars did they wash during the spring car wash? ANSWER: 2x – 14 = 96; 41 cars.
Answer:
C) x=2 y=-1 z=3
Step-by-step explanation:
2x + y - z = 0
2(2) + (-1) - (3) = 0
0 = 0
x - y + z =6
2 - (-1) + 3 = 6
6 = 6
x + 2y + z = 3
2 + 2(-1) + 3 = 3
3 = 3
1)
x^2 + 4 = 0 Subtract 4 from each side
x^2 = -4
You cannot square a number to get a negative number. No real solution. (If you have learned about imaginary numbers, answer is 2i)
2)
<span>x^2+x-6=0 Factor. 3 and -2 add up to 1, and multiply to -6
(x+3)(x-2) = 0
Zero Product Property: Which numbers would put a zero in one of the parentheses?
x = -3 or x=2
3) </span><span>x^2-6x+7=0
Completing the Square:
Take half of b (-6), square it, and add/subtract that coefficient
x^2 - 6x + 9 - 9 + 7 = 0
(x -3)^2 - 2 = 0 Add 2 to both sides
(x-3)^2</span> = 2 Take the square root of both sides
<span>(x-3) = </span>√2 or -√2 Add 3 to both sides
<span>x = 3 + </span>√2 or 3 - √2<span>
</span>
Step-by-step explanation:
For writing the expression, represent 'a number' as x, as it's unknown.
<u>The word format explains;</u>
Four less than x.
Subtracting 4 from x will represent four less than x.
<u>Expression is represented as;</u>
