Given equation of line y=0.25x-7.
On comparing given equation with slope-intercept form y=mx+b.
We get m=0.25.
0.25 could be written 25/100 in simplest fractions 1/4.
Line are perpendicular.
Therefore, slope of the perpendiular line would be reciprocal and opposite in sign of the given slope of the line.
Reciprocal of 1/4 is 4 and opposite of sign of 4 would be -4.
So, the slope of the required line is m=-4.
We are given a point (-6,8).
Applying point-slope form, we get
y-y1=m(x-x1)
y-8 = -4(x- (-6))
y-8 = -4(x+6)
y-8 = -4x -24.
Adding 8 on both sides, we get
y-8=8 = -4x -24+8
y=-4x-16.
Therefore, the equation y=-4x-16 is perpendicular to the given eqution of line.
Yoko would drive 754 miles in 13 hours.
First you would have to find how many miles Yoko drives per hour so you divide 522 miles/9 hours to get 58 miles per 1 hour. Then you multiply 58 * 13 to get 754 miles.
Answer:
Step-by-step explanation:
22 into 2 and 11
2 is already prime and 11 is already prime
Answer:
To prove that the triangle is a right- isosceles triangle, prove that
- There is a right angle in the triangle
- Two sides of the triangle are equal in length
Another way to prove that angle YXZ is a right angle is to calculate the length of XY, XZ and YZ using the distance formula. Then show that (YZ)² = (XY)² + (XZ)².
By the inverse of Pythagoras' Theorem, ∡YXZ is a right angle.
*The product of the gradients of 2 perpendicular lines= -1.
Please see the attached pictures for full solution.
Answer:Domain = R - {3}
R = set of real numbers
Step-by-step explanation:
Domain cant be that number which when put into function gives undefined value. :. in 5/(x-3) , x-3 != 0.
:. we can put any real number in the function to get a value but not 3.HOPES THIS HELP IF YOU HAVE ANY MORE QUESTION JUST COMMENT.
