Answer:
1
Step-by-step explanation:
1) First, place the given equation in slope-intercept form (
format) to find its slope easier. Isolate the y:
So, the equation of the line in slope-intercept form is 
. When an equation is in slope-intercept form, the 
, or the coefficient of the x-term, represents the slope. Thus, the slope for the given line would be -1.
2) Lines that are perpendicular have slopes that are opposite reciprocals of each other. We need to find the opposite reciprocal of -1, then.
To find the opposite reciprocal of a number, write the given number as a fraction first -- making -1 be written as 
-- then switch the sign and flip the numerator and denominator. So, the opposite reciprocal of -1 is 1, and 1 is the slope of the perpendicular line.
Answer:
first make mixed
13/4 x 5/8
just multiply the numerator with numerator and denominator with denominator
13x5=65
4x8=32
65/32 or 2 1/32
Step-by-step explanation:
Answer:
Perimeter = 2 ( l + w )
if u r given for rectangle thats the formula
Since there is a right angle, you can use Pythagoras' Theorem:
So x = √(24² + 7²) = 25

Answer:
25
Answer:
C
Step-by-step explanation:
Equation : -1x² - 14x + 2 = 0General Formula : b2-4ac=0a=-1, b= -14, c= 2Put the Value in General FormD = (-14)2 - 4 x -1 x 2D = 196--8D = 204
and the polynomial has 2 real roots
