Answer:
6/5 or 1 1/5
Step-by-step explanation:
120% = 120 / 100
3 because a polygon has 3 or more sides
Well.. a polynomial expression is an expression that has 3 or more different algebraic terms.
Algebraic terms can be: x^2, 2x, or x^3
One example is: x^2 + x^3 - 7y
Since x^(-2)+5 only has one algebraic term, which is x^(-2), this is not a polynomial.
Answer:
a. (-3,3), (18,-6), (9,15)
Step-by-step explanation:
If the scale factor is 3 and dilation is about the origin, each of the coordinates of the pre-image is multiplied by 3 to get the coordinates of the image.
Multiplying (-1, 1) by 3 gives (-3, 3), which matches choices A and C.
Multiplying (6, -2) by 3 gives (18, -6) which matches choices A and D.
The only viable choice is choice A.
If the hypotenuse is equal to 11, then we can plug it into the Pythagorean theorem. So we get a^2+x^2=121. So we take the square root of both sides, sqrt(a^2+x^2)=11. So we take a^2 and x^2 out of the square root. We get a+x=11. So now we have two equations, a+x=11 and a^2+x^2=121. I’ll leave the rest of solving equations to you.
Hint: a=11-x
You can plug that into a^2+x^2=121
