5k + 30 = -20 - 5k
Solve for K.
5k + 30 = -20 - 5k
5k + 5k = -20 - 30
10k = -50 / : 10
k = -5
Answer:
-5 = k
Step-by-step explanation:
5k + 30 = -20 - 5k
5k + 30 + 20 = 5k + 50
-20 - 5k + 20 = -5k
5k + 50 = -5k
5k + 50 - 5k = 50
-5k - 5k = -10k
50 = -10k
50 / -10 = -5
-10k / -10 = k
-5 = k

Please help if you can!!!
Answer:
Step-by-step explanation:
y = ax² + bx + c
Plug in the three given points, then solve for a, b, c
(-3,0): 0 = 9a - 3b + c
(4,0): 0 = 16a + 4a + c
(0,-12): -12 = c
9a - 3b = 12
3a - b = 4
16a + 4b = 12
4a + b = 3
a = 1
b = -1
y = x² - x - 12

Step-by-step explanation:
Scores on a national math test are Normally distributed, with a mean score of 490 and a standard deviation of 50. Which test score represents the top 20%, rounded to the nearest whole number?
Find the z-table here.
426
448
532
554
Answer:
532
Step-by-step explanation:
The score that represents the top 20% = A score = 80%
Z score for 80% percentile = 0.842
We solve using the z score formula
z = (x-μ)/σ, where
x is the raw score = ??
μ is the population mean = 490
and σ is the population standard deviation = 50
Hence:
0.842 = x - 490/50
Cross Multiply
0.842 × 50 = x - 490
x = 0.842 × 50 + 490
x = 42.1 + 490
x = 532.1
Approximately = 532
Therefore, the test score = 532
Answer:
532

the length of a rectangle is 2 inches less than 3 times it width . The perimeter of the rectangle is 124 inch. WHat is the length of the rectangle
Step-by-step explanation:
let w = width
length = 3w-2
perimeter = 2*length + 2*width
perimeter = 2(3w-2) + 2w
perimeter = 6w - 4 + 2w
perimeter = 8w - 4
perimeter = 124 inch
8w - 4 = 124inch
+4 to each side
8w = 128inch
divide each side by 8
w = 16
length = 3w-2
= 3(16) - 2
length = 46 inch
which is a multiple of 3
