Y = 1.50x + 4......x = 7
y = 1.50(7) + 4
y = 10.50 + 4
y = 14.50 <===
The square of an odd number:
We're to conjecture, not do algebra, apparently. 1²=1, 3²=9, 5²=25, 7²=49, ...
We conjecture the square of an odd number is odd.
The product of two evens and an odd:
Again, we'll run some examples.
(2)(2)(1)=4
(2)(4)(3)=24
(4)(6)(5) =120
(4)(8)(1)=32
Conjecture: The product of two evens and an odd is a multiple of 4
Counterexample: The product of two fractions is never an integer
How about
3/4 × 4/3 = 1
Answer: (8)(-4.5)
Step-by-step explanation:
If you were to multiply-4.5 • -8 that would equal a positive number but if you were to divide (8)(-4.5) it would equal a negative number
0.097 is 97/1000
Hope this helps
Answer:
4
Step-by-step explanation:
they're the same triangle, but one is bigger. the 2,5 and 5 sides are equivalent, so with that we are able to know the big triangle is exactly 2x bigger. u multiply the 2 side (because it's equivalent to the x side) by 2 (bc the triangle is 2 times bigger) and you get 4 = x
