When you have something like this, all you need to do is substitute the values, the last is for what value of x
For the first one;
((x^2+1)+(x-2))(2)
(x^2+x-1)(2)
(2)^2+(2)-1
4+2-1
5
For the second one;
((x^2+1)-(x-2))(3)
(x^2-x+3)(3)
(3)^2-(3)+3
9-3+3
9
For the last one;
3(x^2+1)(7)+2(x-2)(3)
3((7)^2+7)+2((3)-2)
3(49+7)+2(3-2)
3(56)+2(1)
168+2
170
Answer:
y = -10.375x + 126.125
Step-by-step explanation:
(12-95)/(11-3) = -83/8 = -10.375
y = mx + b
12 = -10.375(11) + b
12 = -114.125 + b
b = 126.125
y = -10.375x + 126.125
Answer:
x = 55°
Step-by-step explanation:
From given figure we have
Two lines parallel
As we know simple straight line maintain an angle of 180°
Third line bisecting the two parallel lines at different position
But hold same same angle form both because lines are parallel.
To find angle = 180 - 125 = 55
Example:
378 • 123= x
Start- 378. Then 378. 378. 378
With- •123 ->do. •100 ->•020 -> •003
Then add the answers of the three problems. 37800+ 7560+1134
Which then you will have the answer.
