Answer:
Step-by-step explanation:
2x*2x=4x^2
2x*3=6x
Keep in mind 4x^2-6x
then next part:
3*2x=6x
3*3=9
6x-9
So totally
(4x^2-6x)-(6x-9)
Minus and minus is equal to +
(4x^2-12x+9)+2=45
4x^2-12x+11=45
-11 on both sides
4x^2-12x=34
X= -17/-2
Answer:
Step-by-step explanation:
There are two ways to go about solving this problem, depending on your available time and fluency with the topic:
Solve it “properly”, by graphing the inequalities yourself, then comparing your graph to the available options.
Use the test-taking strategies of “ruling out answers that are clearly wrong”, followed by “use enough of what you know about the problem to select the correct answer.
Let’s walk through both, since you should be able to do both, as this problem looks very much like a practice problem for a standardized Algebra 1 test.
So! To graph a linear inequality, the steps include graphing the line, determining what type of line, and determining how it’s shaded, though the order of these steps is only important if you’re doing math in pen, which is a terrible idea.
The first inequality:
Answer:
it is d
Step-by-step explanation:
Complimentary angles equal 90 degrees. So the answer would be C because 77+13= 90.
