Y=3x+3 use rise over run and the y intercept is y

alexdok [17]3 years ago

Y= 3x + 3. Use rise (how many it goes up or down) and divide it by run (how many it goes left or right) that number is your slope (aka M/ the number that goes with x. The number without the x attached is just where the line crosses the y axis

If f(x) = x² + 7, what is the value of f(4)?

dalvyx [7]

Value of f(4) is $f(4)= 23$ given $f(x)= x^2+7$

Step-by-step explanation:

We are given $f(x)= x^2+7$ and we need to find value of f(4)

Solving:

We will put x=4 and solve the given equation:

$f(x)= x^2+7$

$f(4)= (4)^2+7$

We know (4)^2=16

$f(4)= 16+7$

$f(4)= 23$

So, Value of f(4) is $f(4)= 23$ given $f(x)= x^2+7$

What is the value of x?<br> What is the measure of angle QOR?<br> What is the measure of angle ROS?

Veseljchak [2.6K]

Answer:

x = 26

angle QOR = 31

angle ROS = 59

Step-by-step explanation:

$(x + 5) + (2x + 7) = 90\\ 2x + x + 5 + 7 = 90 \\ 3x + 12 = 90 \\ 3x = 90 - 12 \\ 3x = 78 \\ x = 78 \div 3 \\ x = 26$

Sub x in

$(x + 5) \\ 26 + 5 = 31$

and

$(2 \times 26 + 7) \\ = 52 + 7 \\ = 59$
