Answer: x = 0 or x = 2
Step-by-step explanation:
To solve this, we must note that the two equations speaks of a single function of y. So
y = 2x - 3 = x² - 3
So from.here we can equate the two together and solve for x.
x² - 3 = 2x - 3, biw convert to a quadratic expression
x² - 2x - 3 + 3 = 0
x² - 2x = 0
Now factorize
x( x - 2 ) = 0, so solving for x
x = 0 or x = 2. .I believed getting the 2 won't be a problem
When x - 2 = 0
Then x = 2.
Answer:
3-they are cubes of consecutive natural numbers
1 cube is 1
2 cube is 8
3 cube is 27
and so on...
let me know if you're asking fourth one or third one
Answer: x =9
Step-by-step explanation:
These are corresponding angles, meaning they are equal. (the same angle). Set them equal to each other to solve. 13x+ 3 = 12x +12. Subtract 3 from both sides. 13x = 12x + 9. Subtract 12x from both sides. X = 9
120 + 90 = 210 points
350 - 210 = 140 OR
351 - 210 = 141 (if it must be more than 350, you need <em>at least </em>351 points total, or 141 more points, to get a grade B)
X = Juan's age
y = Eliza's age
Some key words/phrases we can use to help us make the equation are:
-is (whatever comes after this word usually equals the end result, or what it equals)
-two years younger
-than
-half her brother's age
.
just break it down :)
x/2 (half her brother's age) - 2 (two years younger) = y (Eliza is...)
| basically,
v
x/2 - 2 = y
So if Juan is 6, then we need to plug in 6 for x.
6/2 - 2 = y
3 - 2 = y
1 = y
ANSWER: Eliza is one year old.
