Y = kx
4.8 = 4k
k = 4.8/4 = 1.2
Therefore, required equation = y = 1.2x
1) y:10;
2) 4p+6q;
3) x +( x+ 1) = 59 => 2x = 58 => x = 29 => 29 and 30;
X² - 16x + 17 = 0
x² - 16x + 8² - 8² + 17 = 0
(x - 8)² - 64 + 17 = 0
(x - 8)² - 47 = 0

Answer: y = (x - 8)² - 47 (Answer D)

Answer:
$3.75
Step-by-step explanation:
dimes= x
quarters= x+2
nickels= 2x+2
sum is 3.75
.10x+.25(x+2)+0.05(2x+2)=3.75
.10x+.25x+.50+0.10x+0.10=3.75
0.45x=3.15
x=7 dimes (0.70)
x+2=9 quarters (2.25)
2x+2=16 nickels (0.80)
They add to $3.75
Answer:
Step-by-step explanation:
x and 52 are supplementary, so they add up to 180°
