X^2+34=74
minus 34 from both sides
x^2=40
sqrt both sides
x=+/-√40
x=+/-2√10
the values 2√10 and -2√10 are soltuions for x
Answer:
y= 3x -4
Step-by-step explanation:
The equation of a line can be written in the form of y=mx +c, where m is the slope and c is the y-intercept. This is also known as the slope-intercept form.
Since the given equation is in the slope-intercept form, we can identify its slope from the coefficient of x.
Slope= -⅓
The product of the slopes of perpendicular lines is -1.
Slope of perpendicular line
= 3
Thus, the equation of the perpendicular line is given by:
y= 3x +c
Substitute a pair of coordinates that the line passes through to find the value of c.
When x= 3, y= 5,
5= 3(3) +c
5= 9 +c
<em>Minus 9 on both sides:</em>
c= 5 -9
c= -4
Hence, the equation of the perpendicular line is y= 3x -4.

Step-by-step explanation:
First, you’d do 10$ spent on lunch and the 35$ spent on the jeans or pants. You add those together to get 45$. You then subtract that from $134.25. Your answer should be $89.25. Now, divide 89.25 by 12.75 to get 7. 7 shirts!
Answer:
-8
Step-by-step explanation:
substitute
x=4
into -3x+2(y-1):
x=3
-3x4+2x(3-1)
-12+2x(3-1)
-12+2x2
-12+4
= -8
