Answer:
x= -3, 4 or 5
Step-by-step explanation:
if you factor out the expressions, they look like this:
(x+3)(x-4)(x-5) = 0
Answer:
10.25%
Step-by-step explanation:
imagine the number is 100. Increase that by 5% so multiply 100 by 105%. This equals 105. Then increase 105 by 5% so multiply 105 by 105%. This equals 110.25. The original number was 100 so 110.25-100= 10.25. 10.25/100= 10.25%
Hope this is correct :) I'm rly not sure now
Answer:
From my research the equation -2(x+y)+9=1 is linear
Answer: 88 degrees; acute triangle
Step-by-step explanation:
All angles of a triangle must add up to 180 degrees. Therefore, to find the value of "x", the work must look like this: 43+49=92 --> 180-92=88. This triangle can be classified as an acute triangle since all of its angles are acute (less than 90 degrees).
Answer:
y=7.5x-76.5
Step-by-step explanation:
If graphs are parallel, that means that they have same slope but different y-intercept. So for new equation slop will be 7.5. y=7.5x+?. Now we have to solve for ? which is also known as y-intercept. To solve it, we have to put values into that equations using coordinates. So coordinate is (11,6) which means that if x is 11, y is 6. When we put this information to new graph equation, it will be 6=7.5(11)+?. When you multiply 7.5 and 11, you get 82.5. So the equation will be like this. 6=82.5+?. Now lets solve for y-intercept. You'll have to subtract 82.5 on 6. 6-82.5=-76.5. So we got y-intercept which is -76.5. Now lets put all the information into one equation. y=7.5x-76.5. That's you're equation of the line that passes through the point (11,6) and is parallel to y=7.5x-3. It is important you to understand this type of questions and not stuck again on same types of questions. Please study more even though you can solve any questions like this. Thank you for reading this long paragraph. Good luck with you're EOC!
