Answer:
Step-by-step explanation:
Because those 2 lines are parallel, then 2x + 10 and 2x - 30 are same side interior and are supplementary. Therefore,
2x + 10 + 2x - 30 = 180 and
4x - 20 = 180 and
4x = 200 so
x = 50
Answer:
Step-by-step explanation:
Starting with ΔABC, draw the dilation image of the triangle with a center at the origin and a scale factor of two. Notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). Dilations involve multiplication! Dilation with scale factor 2, multiply by 2
Answer:
Integers and polynomials are both <u>closed </u>under addition, subtraction, and multiplication; however, operations on polynomials <u>can sometimes be open </u>while operations on integers <u>produce irrational results
</u>.
Step-by-step explanation:
Closed means that addition, subtraction, and multiplication of integers gives as result a new integer; and addition, subtraction, and multiplication of polynomials gives as result a new polynomial.
Operations on polynomials can sometimes be open, like in division.
Operations on integers can produce irrational results
, for example, dividing 11 by 9.
I'm going to assume that you know what an integer is, and that 1 is an integer. I'm also going to assume you've learned what a mixed number is. If not, a mixed number is a decimal changed into a fraction. So rather than write "1.5" as an answer, you can leave it as a fraction and get 1 1/2.
The same thing can be done to any type of rational fraction. 1.1, 1.2, 1.3, etc. If you choose to use any of those, the numerator will be the number you choose to do (1,2,3, etc) over 10.
I hope I was able to help. Best of luck!
