Answer:
the answer is b
Step-by-step explanation:
the x axis is left and negative units would go to the left
the y axis is up and down so positives would go up
The second box to the left side
Let's give the variable that you are trying to answer for a symbol. Let's call it X.
X = the amount of money both Greg and Thomas had in October
We know that in November, Greg added $120 to his account. So, Greg's account has: X + 120
We know that Thomas increased the money in his account by 20%, so Thomas' account has: X + 0.2X, or 1.2X
We know that these two amounts are equal:
X + 120 = 1.2X
Solve for X:
X + 120 - X = 1.2X - X
120 = .2X
120 / .2 = .2X / .2
600 = X
Answer:
measure of angle YVZ=56°
Step-by-step explanation:
angle WVY and angle YVZ form a right angle, meaning they add to 90 degrees.
We can make an equation out of this:
2x+3x+5=90
solve for x
5x+5=90
5x=85
x=17
substitute x back into the expression for angle YVZ because that's the measure we're looking for
angle YVZ=3(17)+5=56
Answer:
D. du/dx = 2x
Step-by-step explanation:
Given to find dy/dx where;
Then when you let;
u=x²+2 and
Then
In u=x²+2 du/dx = 2x------------------------step 1
In e^4x, dv/dx = e^4x * d/dx (4x)
=e^4x *4 = 4e^4x------------------------------------step 2
