Answer:
Step-by-step explanation: x^2 : (20 - 3x) = 1 : 2
2x^2 + 3x - 20 = 0
(x + 4)(2x - 5) = 0
Solution:
x = -4
x = 5/2
Answer:
( 39/50 ) * c
Step-by-step explanation:
Sale price = Original price - Reduced price
= C - (C * 22%)
= ( 39/50 ) * c

Answer:
Step-by-step explanation:
Slope m = (-8-2)/(1+1)=-10/2 = -5
Perpendicular slope-1/m = -1/-5 = 1/5
Equation of a line with perpendicular slope is
y-y1=(-1/m)(x-x1)
y - 2 = (1/5)(x+1)
y =2 +(1/5)(x+1)
Answer:
C) 33 meters
Step-by-step explanation:
In this question, we need to find the value of the variable "x".
To do this, we must use the Pythagorean theorem: a² + b² = c²
Plug in your values and solve:
56² + b² = 65²
3,136 + b² = 65²
3,136 + b² = 4,225
Subtract 3,136 from both sides.
b² = 1,089
To cancel out the exponent, we would square root both sides.
√b² = √1,089
b = 33
This means that C) 33 meters will be your answer.
