For #1 you're just plugging in the numbers that are in the parentheses for x.

For example:
f(2)
Take the given equation to plug in for x:

x^2-4x+5

(2)^2-4(2)+5

And from there you get the answer. Your final answer will look like this:

f(2)=? {the answer you got when you plugged in}

Solve the system of linear equations by substitution.<br><br> 8x−13y=0<br> 12x+3=y
Oliga [24]

Answer:

x = - 39/148

y = -6/37

Step-by-step explanation:

substitute the given value of y into the equation to get 8x-13 (12x+3)=0

solve for x to get x= - 39/148

substitute the given value of x into 12x+3=y

12 x (-39/148) + 3 = y

-6/37 = y

A discount book store sells hardcover books for $8 each and paperbacks for $4 each.The number of hardcover books, h, sold one da
vaieri [72.5K]

Jean-Paul's error is that he should have written the second equation as h = 4 p + 2.

<h3 />

<h3>How to solve an equation?</h3>

The hardcover book is $8 each and paperbacks for $4 each.

The number of hardcover books, h, sold one day was 2 more than four times the number of paperback books, p, sold that same day.

Therefore,

h = 4p + 2

Hence,

8h + 4p = 160

Therefore, the right equation are as follows:

h = 4p + 2

8h + 4p = 160

Hence, Jean-Paul should have written the second equation as h = 4 p + 2.

Number 5 am stuck pls help
Norma-Jean [14]

Answer:

im going to be honest i havent done this since las year and so i dont remember the value of that line outside but i think its 70*

Step-by-step explanation:

reason is because the c is originally 180* but it has more of and angle so the angles obv increases and you can get the angle by multiplying 70*times 7x and divide by 3

i say 3 because of the amount of angles in a triangle and the line outside if i remember correctly is the "angles" of a triangle  and that would be your answer

What equations is equivalent to y = log x
saw5 [17]

"log" standing alone actually means "logarithm to the base 10."


Thus, y = log x   <=>   y = log      x
                                               10
                                                                           y
 Stated another way (inverse functions), x = 10
