A = a^2
112 = a^2
sqrt 112 = a
sqrt 16 * sqrt 7 = a
4 sqrt 7 = a
so 4 sqrt 7 is the length of each side
Answer:
x= 95/2 or x=47.5 or 47 1/2
Step-by-step explanation:
3x + 10 = 5(x - 17)
First Step:
multiply and combine the right side (parentheses)
5 times x = 5x 5 times -17 = -85
3x + 10 = 5x -85
Second Step:
Add like terms ----> which is: 3x and 5x -----10 and -85
BUT since you only want one x on one side, you combine x first.
3x + 10 = 5x -85
-5x -5x
-2x + 10 = -85
NOW
Third Step: Add the integers---> 10 and -85
you want to get 10 on the same side as the -85, so you subtract it from BOTH sides.
which brings you:
-2x + 10 = -85
-10 -10
<u> </u>
NOW that we've subtracted -10 from -85 it's technically just adding 85 and 10 then putting a negative sign on it.
so now we have:
-2x = -95
Step Four:
divide -2 from each side to get X alone
<u>-2x</u> = <u>-95</u>
-2 -2
ANSWER:
x=47.5
Answer:
−18y+48
Step-by-step explanation:
The correct answer is
<span>5 - 4 + 7x + 1 = 7 x + 1</span>
First, we need to evaluate the function to get two points, and then we connect them with a line.
<h3>
How to graph a linear function in math?</h3>
The linear function in the slope-intercept form is:
f(x) = a*x + b
Where x is the variable.
To graph it, we need to find two points on the line, to do that, we evaluate in two values of x. Let's use x = 0 and x = 1.
for x = 0:
f(0) = a*0 + b = b
for x = 1:
f(1) = a*1 + b = a + b
Then we have the points: (0, b) and (1, a + b).
Now we only need to graph these two points and connect them with a line, that line will be the graph of the linear function.
