Solve:
5x + 10 = -15
Answer:
x= -5
Step-by-step explanation:
5x + 10 = -15
subtract 10 from both sides
5x = -25
divide both sided by 5
x = -5

2x^2+2=3x complete the square i need full explaination ASAP
Answer:
x = 3/4 + √7i/4
x = 3/4 - √7i/4
Step-by-step explanation:
2x² + 2 = 3x
Subtract 3x from both sides so it equals 0:
2x² - 3x + 2 = 0
Divide both sides by 2:
x² - 3/2x + 1 = 0
Subtract 1 from both sides:
x² - 3/2x = -1
Take -3/2 and multiply it by 1/2 then square it:
(-3/2 • 1/2)²
9/16
Add this to both sides:
x² - 3/2x + 9/16 = -1 + 9/16
Rewrite the perfect square on the left and add the terms on the right:
(x - 3/4)² = -7/16
Square root both sides to get rid of the square:
x - 3/4 = ± √-7/16
Simplify the radical:
x - 3/4 = ± √7i/4
Add 3/4 to both sides:
x = 3/4 ± √7i/4
Your two solutions are:
x = 3/4 + √7i/4
x = 3/4 - √7i/4
You can also convert to decimal if you need to (but I don’t recommend it):
x = 0.75 + 0.661438i
x = 0.75 - 0.661438i
Hope this helps!

Alex needs to bisect ∠ABC using a compass and straightedge. He starts by performing the following steps. Step 1: Place the compass on vertex B of the angle. Step 2: Draw an arc that intersects both sides of the angle. Step 3: Label these intersections as point D and point E . Step 4: Place the compass at point D and draw an arc in the interior of the angle. What are the next steps Alex should take in his construction?
Answer:
Step 5: Without changing the length of the compass place it on point E and draw an arc in the interior of the angle.
Step 6: Draw a straight line with the straight edge that goes from the vertex and thru the intersection of both arcs.
Step-by-step explanation:
To bisect and angle is to split it prefectly in half, making for example a 90º angle into two 45º angles, in order to do this you will just need to use your compass and draw an arc that will pass over both sides of the angle, after that you put it in the intersections of the arc and the sides and just draw arcs that fit inside the angle from there where both arcs created from the intersections of the precious arc meet that's the middle of the angle, so now you just draw a straight line from the vertex to the intersection of both arcs and you just have bisected an angle.

Determine whether the ordered pair (coordinate) is a solution to the inequality.
2. 2x + 3y > -8,
(3,-6)
Answer:
The ordered pair is not a solution to the inequality.
Step-by-step explanation:
Given expression;
Inequality :
2x + 3y > -8
Ordered coordinate pair = (3, -6)
Solution:
If the ordered pair is a solution of the inequality, then it must be true that expression on the left -hand side is greater than -8;
So, the values we get on the right-hand side should be -7, -6 on and on.
x = 3 and y = -6
Input the parameters into the inequality;
2(3) + 3(-6)
= 6 - 18
= -12
-12 is less than -8 and this is not correct for the expression.
The ordered pair is not a solution to the inequality.

5 7/12 + 4 6/12 = 9 13/12 = 1 1/12 what's the error analysis?
Answer:boo
Step-by-step explanation:booooo
Answer:
5 7/12 + 4 6/12 = 9 13/12 is correct but 9 13/12 is equal to 10 1/12 not 1 1/12 because 13/12 is 1 1/12 and you have to add 1 1/12 to 9. So the error analysis is simplifying 9 13/12 to 1 1/12.
What is the solution to this equation?

O A. x = 6
O B. x = 30
O C. x = 4
O D. x = 20
Answer:
A. X = 6.
Step-by-step explanation:
First, combine like-terms. Combine 3X and 2X to get 5X.
Next, add five to both sides to get rid of the five on the other side. This should get you 30.
Finally, divide by 5, you should get X = 6.

have 5 employees.
2. The store rent is Php 40,000.
3. Utilities expenses amount to Php 20,000.00
4. 200 pieces of your product were sold at Php 1000.00 each.

Answer: Yes the business made a profit for the month. They made $90,000 net profit. They made a profit of $90,000 after all the taxes were deducted.
Step-by-step explanation: 200 times $1000 = $200,000. $200,000 - $50,000 = $150,000. $150,000 - $40,000 = $110,000. $110,000 - $20,000 = $90,000
