Answer:
y - Q = -5/2(x - P)
Step-by-step explanation:
The equation of a line in point slope form is expressed as y - y0 = m(x-x0)
(x0, y0) is the point
m is the slope
Given the equation
y = 2/5x− 4.
Slope m = 2/5
Slope of the perpendicular line = -1/(2/5) = -5/2
Point;
x0 = P
y0 = Q
Substitute into the formula;
y - y0 = m(x-x0)
y - Q = -5/2(x - P)
This gives the required equation
Answer:
245
Step-by-step explanation:
let 'c' = total coins
2/7 = 70/c
2c = 490
c = 245
Answer:

Step-by-step explanation:
Given
x +
≤ - 3 or x - 3 > - 2
Solve the left and right inequalities separately, that is
x +
≤ - 3 ( isolate x by subtracting
from both sides )
x ≤ - 3 -
, that is
x ≤ -
-
, thus
x ≤ - 
OR
x - 3 > - 2 ( isolate x by adding 3 to both sides )
x > 1
Solution is
x ≤ -
or x > 1
Answer:
Step-by-step explanation:
412
Answer:
2*2*3*3*5
Step-by-step explanation:
Factor 180 into prime numbers that multiply together to give 180
180 = 20 *9
= 4*5 * 3*3
= 2*2* 5 * 3*3
Now rewrite them from smallest to largest
2*2*3*3*5
