Consider the system of equations.

y = 3x + 2
y = -2/3x − 4

Explain why these particular equations can be graphed immediately.

Answers

Answer 1

Answer:

because you have the y intercept to plot and the slope to go off of from there

same for the second one

Answer 2
The equations are in slope-intercept form making them easy to graph.

Slope-intercept form: y = mx + b
plot y-intercept first (0,b)
then go rise over run for the slope to find other points.
Draw line through points

Answer: 35°

Step-by-step explanation: the total of a triangle's angles always equals 180° and we know 2 of the angles so if you add the two (55+90=145) and subtract that from 180 (145-180=35) you get 35°

Answers

Answer:

150 votes were casted

Step-by-step explanation:

So first, we know that Amy received 48 votes. Then Neil received 1/4 as many votes as Amy. So we can divide 48 by 4:

48/4=12

Neil got 12 votes. We also know that Neil and Amy's votes together is only 40% of the votes casted in total. So we can add their votes together and then find a fifth of the votes casted by dividing the 40% in half:

12+48=60

60/2=30

So now 30 votes are 20% of the total votes casted, now we just have to multiply by 5:

30*5=150

150 votes were casted

Answer :

150 cast votes

Answers

Answer: 4.18$ or 4.19$ per shirt (I’m not entirely sure my answer is correct but do what you must with this info)

Step-by-step explanation: 200 times 2.80 is 560,

5% of 560 is 588,

150% of 588 is 882,

and then 882 divided by 200 is 4.18 (or 4.19)

look at all of this math. do it all or something for 50 points each ig
(a + b)2 = a2 + 2ab + b2
(a – b)2 = a2 – 2ab + b2
(a + b) (a – b) = a2 – b2
(x + a)(x + b) = x2 + (a + b)x + ab
(x + a)(x – b) = x2 + (a – b)x – ab
(x – a)(x + b) = x2 + (b – a)x – ab
(x – a)(x – b) = x2 – (a + b)x + ab
(a + b)3 = a3 + b3 + 3ab(a + b)
(a – b)3 = a3 – b3 – 3ab(a – b)
(x + y + z) 2 = x2 + y2 + z2 + 2xy + 2yz + 2xz
(x + y – z) 2 = x2 + y2 + z2 + 2xy – 2yz – 2xz
(x – y + z)2 = x2 + y2 + z2 – 2xy – 2yz + 2xz
(x – y – z)2 = x2 + y2 + z2 – 2xy + 2yz – 2xz
x3 + y3 + z3 – 3xyz = (x + y + z)(x2 + y2 + z2 – xy – yz -xz)
x2 + y2 = 1212 [(x + y)2 + (x – y)2]
(x + a) (x + b) (x + c) = x3 + (a + b +c)x2 + (ab + bc + ca)x + abc
x3 + y3 = (x + y) (x2 – xy + y2)
x3 – y3 = (x – y) (x2 + xy + y2)
x2 + y2 + z2 -xy – yz – zx = 1212 [(x-y)2 + (y-z)2 + (z-x)2]
