Answer:
(x - 10)(x + 10)
Step-by-step explanation:
x² - 100 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
Hence
x² - 100
= x² - 10² = (x - 10)(x + 10)
Answer:
y = (5x – 9) ÷ (–4)
Step-by-step explanation:
3 − 4y = 5x − 6
–3 –3
–4y = 5x – 9
÷(–4) ÷(–4)
y = (5x – 9) ÷ (–4)
To find the x int, we will sub in 0 for y and solve for x...um...r
- 2r + 1/2y = 18
-2r + 1/2(0) = 18
-2r = 18
r = -18/2
r = -9
so the x int is (-9,0)
