idk maybe its c
Step-by-step explanation:
Answer:
-288
Step-by-step explanation:
n=1/2 divided by -144. You then just plug that number which is .00347 into n in the equation and use a scientific calculator to find the answer.
Answer:
45 members are in the choir.
Step-by-step explanation:
Set up an equation:
Variable x = boys
3/6 = x/30
Cross multiply:
3 × 30 = 6 × x
90 = 6x
Divide both sides by 6:
15 = x
There are 15 boys.
To find the number of members in the choir, add the number of boys and girls:
30 + 15 = 45
Your classmate is correct, though this is not explicitly what the midpoint formula is necessarily set out to do. If one is given two sets of endpoints, one can discover the midpoint by finding the mean distance between these two endpoints. For example, if two points are 10 and 2, all you need do to find the midpoint is add the two poles and divide them by 2 (that is, find the average). The same applies for coordinate geometry, except with additional variables, the formula to find the coordinates of a midpoint is: M= (x1+x2/2, y1+y2/2). Thus, two averages (of both the x coordinates and y coordinates are taken). Your classmate is correct if two endpoints are given, think of a line with two poles, the middle of this line must be the midpoint.
Option 2: whenever it’s < or > it’s a dashed line but when it’s <= or >= it’s a solid line
Option 4: if you’ll insert (0,0) in the equation then you’ll get 0>-2 which is true so (0,0) is a solution. Another way to check is if (0,0) is in the shaded region of the graph
Option 5: in the equation-2 is the y-intercept which proves it intersects at (0,-2) on the y-axis
