y = - 4x - 2
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y = - 4x - 5 is in this form
with slope m = - 4
• Parallel lines have equal slopes
y = - 4x + c ← is the partial equation
To find c substitute (- 2, 6 ) into the partial equation
6 = 8 + c ⇒ c = 6 - 8 = - 2
y = - 4x - 2 ← equation of parallel line
The answer is 247.000. Hope this helps.
She earned $184 in interest.
$644 in all.
Here's why:
The formula is interest = principal x rate x time.
i = 460 x 8% x 5 or i = 460 x 0.08 x 5.
PEMDAS
460(0.08) = 36.8
i = 36.8 x 5
36.8 x 5 = 184
i = $184
To find them in all, add the original amount she deposited with the interest.
460 + 184 = 644
In all: $644
Answer:
1/3
Step-by-step explanation:
Perpendicular lines have a slope that is the opposite reciprocal of the original line slope. To find it, first flip the fraction (-3 to -1/3). Then, add/get rid of the negative sign based on if it was there in the first place (-1/3 to 1/3). Thus, the slope would be 1/3.
Hope this helped :)
