Answer: (x+20) (x+1)
Step-by-step explanation:
Answer:
$98.33 was deposited in the account
Step-by-step explanation:
simple interest formula = (PRT)/100 ...where p is money, r is rate, t is time
using formula $17.70 = (P * 3% * 6)/100
P = 1770/18
P = $98.33
6x^3+8x^2-10x-4 multiplied
no solution.
The two lines are parallel
(same slope but different y intercepts)
Answer:
y= -2x
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Given that the slope is -2, m= -2.
subst. m= -2 into the equation:
y= -2x +c
To find the value of c, substitute a coordinate.
When x= -4, y=8,
8= -2(-4) +c
8= 8 +c (expand)
c= 8-8 (-8 on both sides)
c=0 (simplify)
Thus, the equation of the line is y= -2x.
