Answer:
Replace all occurrences of +− with a single −. A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign because 1⋅−1 = −1
Y=x²−10, Y=2x−4
Eliminate the equal sides of each equation and combine.
x²−10 = 2x−4
Solve x²−10 = 2x−4 for x.
x= 1+√7, 1−√7
Evaluate Y when x = 1 + √7.
Y =−2 + 2√7
Evaluate Y when x = 1 − √7.
Y=−2 − 2√7
The solution to the system is the complete set of ordered pairs that are valid solutions.
(1+√7,−2+2√7)
(1−√7,−2−2√7)
The result can be shown in multiple forms.
Point Form:
(1+√7, −2+2√7), (1−√7, −2−2√7)
Equation Form:
x= 1+√7, y= −2+2√7
x= 1−√7, y= −2−2√7
Step-by-step explanation:
Answer:x>2
Step-by-step explanation:
4x/4>8/4
Answer:
I think his age is 39.
Step-by-step explanation:
If Cesar's age was 2 times Rosa's 6 years ago, that means their combined ages 6 years ago was 66. 66 dived by 2 is 33 and 33 plus the 6 years is 39.
Answer:
n=46
Step-by-step explanation:
Since this is a right triangle, you are left with 90 degrees
2n-2=90
2n=92
n=46
