Answer:
22) 119
24) 15
Step-by-step explanation:
22) 61 + b = 180 <-- supplementary because on the same line
b = 119 <-- subtracted 61 from both sides
24) 87 + (6x + 3) = 180 <-- supplementary because on the same line
87 + 6x + 3 = 180 <-- take out parantheses
90 + 6x = 180 <-- add like terms
6x = 90 <-- subtracted 90 from both sides
x = 15 <-- solve for x by dividing 6 from both sides
Answer: It is gvgtyhf
Step-by-step explanation:
Hello
<span>y= e^x (x^2 -7x +13)
y' = (</span>e^x)' (x^2 -7x +13)+e^x (x^2 -7x +13)'
y' = e^x(x^2 -7x +13)+e^x (2x-7)
y" = e^x(x^2 -7x +13)+e^x (2)
y"=e^x(x^2 -7x +15)
