Hello,
The line passing by (0,6) and (2,0) has for equation 3x+y-6=0.
The origine (0,0) is in the region 3*0+0-6=-6 : negative.
So 3x+y-6>0 is the region positive.
If the line is taken : 3x+y-6≥0.
The answer to this one is 4
Answer:
t = 2.64 or
Step-by-step explanation:
v(t) =
v(t) = -32t + C
when t = 0, the velocity is 12
12 = -32(0) + C
C = 12
v(t) = -32t + 12
now finding position
when t = 0, position is 80
80 = 0 + C, C = 80
now finding when position = 0
0 =
0 =
t = -1.89, 2.64
t>0, so t = 2.64
The value of t is (D) 55/9.

What is an equation?</h3>
- An equation is a formula in mathematics that expresses the equality of two expressions by connecting them with the equals sign =.
- The word equation and its cognates in other languages may have subtly different meanings; for example, in French, an équation is defined as containing one or more variables, whereas in English, an equation is any well-formed formula consisting of two expressions linked by an equals sign.
To find the value of t:
Given -
- (t+5)/(t-5) = 10
- t+5 = 10(t-5)
- t+5 = 10t - 50
- 10t - t = 5 + 55
- 9t = 55
- t = 55/9
Therefore, the value of t is (D) 55/9.

The sum of the interior angels is 180(n-2). In this case 180(5-2)= 540. So the equation is 540=100+103+4x+(3x+3)+(5x-2). Then solve for x. X=28
