Anon25 [30]

Answer:

6%: $1776
12%: $7353

Step-by-step explanation:

Let x represent the amount invested at 6%. Then the amount invested at 12% is 4x+249. Sherrie's interest is ...

0.06x +0.12(4x +249) = 988.92

0.54x + 29.88 = 988.92

0.54x = 959.04

x = 959.04/0.54 = 1776

4x+249 = 7353

Sherrie invested $1776 at 6% and $7353 at 12%.

kogti [31]

Answer:

0/13 This is a zero slope

Step-by-step explanation:

y2-y1/x2-x1

if the number in the numerator is a zero, it is a zero slope. if the zero is in the denominator it is undefined

trick for remembering zero slope vs undefined: if the zero is UNDEr it is UNDEfined- this makes more sense if you say it out loud ;)

The point (4,-2) is the vertex of the graph of a quadratic function. The points (8,6) and (2,0) also fall on the graph of the fu

Elina [12.6K]

Answer:

Step-by-step explanation:

y = ax² + bx + c

~~~~~~~

(4, - 2), (8, 6), (2, 0)

a(4²) + b(4) + c = - 2

a(8²) + b(8) + c = 6

a(2²) + b(2) + c = 0

16a + 4b + c = - 2 .............. (1)

64a + 8b + c = 6 ............... (2)

4a + 2b + c = 0 ................. (3)

a = 0.5 ; b = - 4 ; c = 6

y = 0.5x² - 4x + 6

Part A: (0, 6), (6, 0)

Part B: (0,6)

Part C: (6, 0)

Part D: [ 4, ∞ )
