Step-by-step explanation:
y=-3+5x
substitute y into equation 2
3x-8y=24
3x-8(-3+5x)=24
3x+24-40x=24
x=0
y=-3+5(0)
y=-3
(x,y)=(0,3)
Answer:
8n^2+7n+2/3
Step-by-step explanation:
combine like terms
5n+2n=7n
Please use * to denote mult. here, not "x." "x" is your variable and cannnot also be a symbol for mult.
f(x)g(x) = 3x^3 - 5x^2.
Now let x = 3:
(f*g)(3) = 3(3)^3 - 5(3)^2 = 81-45 = 36 (answer)
8x²-8x+2-5+x = 8x² - 7x - 3
Thus, g = 7 and h = 3
Round to the biggest place value, 2,356 in the thousands place so the thousandths place is the greatest value there so 2,356 rounded to the nearest thousandths is 2,000
