Answer:
a line parallel to the line y = 5x + 2 ---> y' = 5x + b (b ≠ 2)
y' = 5x + b goes through (-4, 3) ---> 3 = 5 × ( -4 ) + b ---> b = 23
⇒ y' = 5x + 23
Answer: x = 33°
Step-by-step explanation: A triangle's angles should all equal 180, so we can set up an equation to help us.
106 + 41 + x = 180
Add 106 and 41
147 + x = 180
Subtract 147 on both sides.
x = 33
And there you go :)
The third graph or bottom left graph represents ![f(x) = 0.2^{x} + 3.](https://tex.z-dn.net/?f=f%28x%29%20%3D%200.2%5E%7Bx%7D%20%2B%203.)
Step-by-step explanation:
Step 1:
To determine which of the given graphs represents the equation
, we substitute some values in the place of x.
When
![f(x) = 0.2^{x} + 3, f(0) = 0.2^{0} + 3= 4.](https://tex.z-dn.net/?f=f%28x%29%20%3D%200.2%5E%7Bx%7D%20%2B%203%2C%20f%280%29%20%3D%200.2%5E%7B0%7D%20%2B%203%3D%204.)
Anything with an exponent of 0 will equal 1.
So the graphs on the right side cannot be the answers.
Step 2:
Now we substitute another value to determine which graph represents ![f(x) = 0.2^{x} + 3.](https://tex.z-dn.net/?f=f%28x%29%20%3D%200.2%5E%7Bx%7D%20%2B%203.)
When
![f(x) = 0.2^{x} + 3, f(1) = 0.2^{1} + 3= 4.2.](https://tex.z-dn.net/?f=f%28x%29%20%3D%200.2%5E%7Bx%7D%20%2B%203%2C%20f%281%29%20%3D%200.2%5E%7B1%7D%20%2B%203%3D%204.2.)
The value of f(x) when
is lesser than the value of f(x) when ![x =0.](https://tex.z-dn.net/?f=x%20%3D0.)
So the third graph or bottom left graph represents ![f(x) = 0.2^{x} + 3.](https://tex.z-dn.net/?f=f%28x%29%20%3D%200.2%5E%7Bx%7D%20%2B%203.)
Answer:
$1.21
Step-by-step explanation:
Start by finding the total amount spent on shirts. Do this by multiplying $3.65 and 4 together. You will get 14.6. So, he spent $14.60 on 4 shirts. Take this amount and subtract it from the total amount paid for shirts and socks. $23.07 minus $14.60. This will give you $8.47 left to spent on socks. $8.47 divided by 7 is $1.21. Therfore, James paid $1.21 per pair of socks.
