Answer: the first answer choice
Step-by-step explanation: it’s nonlinear because it has a changing slope, and the graph crosses the y axis at -3
Answer:
∠ B = 54°
Step-by-step explanation:
Supplementary angles sum to 180°.
Sum A and B and equate to 180, that is
7x + 14 + 5x - 26 = 180, that is
12x - 12 = 180 ( add 12 to both sides )
12x = 192 ( divide both sides by 12 )
x = 16
Thus
∠ B = 5x - 26 = 5(16) - 26 = 80 - 26 = 54°
8x +7y = 39 multiply everything by 2
2(8x +7y = 39)
16x +14y = 78
+4x - 14y= -68
-------------------------
20x = 10
20x /20 = 10/20
x = 1/2
Plug x into first formula
8 x + 7y =39
8(1/2) 7y=39
4+ 7y =39
4-4+7y =39-4
7y =35
7y/7 = 35/7
y = 5
(1/2, 5)
Answer:
(x+4)^2 Choice A
Step-by-step explanation:
x^2 + 8x + 16
what 2 numbers multiply together to give you 16 and add together to give you 8
1*16 = 16 1+16 = 17 no
2*8 = 16 2+8 = 10 no
4*4 = 16 4+4 = 8 yes
(x+4) (x+4)
(x+4)^2
Answer:
3.7 million
Step-by-step explanation:
14,100,000 = 3,000,000 + 3p
3p = 11,100,000
p = 11,100,000 / 3
p = 3,700,000
