Answer:
y-intercept (0, 8)
Step-by-step explanation:
Plug in (1,4) --> (x,y) and solve for b (y-intercept):
y = -4x + b
4 = -4(1) + b
4 = -4 + b
b = 8
Therefore the y-intercept is (0, 8)
The nearest ten thousand is 20,000
Step-by-step explanation:
Multiply everything in the parenthesis.
24. (2xy)( -4x²) + (6x)(6x²y)
---> -8x³y + 36x³y
= 28x³y
25. (2ab²)(4a²b³) - (10a³b)(6b⁴)
---> 8a³b^5 - 60a³b^5
= -52a³b^5
Sorry, i cant turn the 5 into an exponent on my phone lol. but i hope this helps.
