Answer:
a. 6(7) + 2(3)^2 = 60
b. (5(-18)/3)-2 = -32
c. (6(10))^2 - 10/5 = 3598
d. (1-3)(1+2) = -6
Step-by-step explanation:
2x - 2 < -12
2x < -12 + 2 add 2 to each side
2x < -10 perform the addition on the right side
x < -10 / 2 divide each side by 2
x < -5 perform the division on the right side
2x + 3 > 7
2x > 7 - 3 subtract 3 from each side
2x > 4 perform the subtraction on the right side
x > 4 / 2 divide each side by 2
x > 2 perform the division on the right side
These are just like equations, except the you have to change the direction of the sign when you multiply or divide by a negative number
(C) x < -5 or x > 2
Answer:
I don't use Geogebra, but the following procedure should work.
Step-by-step explanation:
Construct a circle A with point B on the circumference.
- Use the POINT and SEGMENT TOOLS to create a circle with centre B and radius BA.
- Use the POINT tool to mark points D and E where the circles intersect.
- Use the SEGMENT tool to draw segments from C to D, C to E, and D to E.
You have just created equilateral ∆CDE inscribed in circle A.
If you mean graphically x^2+500 would work on a graph
