Answer:
you add them, but keep the sign
Step-by-step explanation:
a. If we subtract 75 from 550 twice, we get 400, which is the third member to join. Subtract 75 from 400, we get $325, the fourth member to join.
b. It is not possible that a member would join for free if it was a large family. 75 does not fit into 550 evenly. You can prove this by solving the expression 550÷75.
c. The lowest amount that a member would pay to join is $25.00. It would be the 7th member.
The area of the Triangle PQR which is in the circle, is given as 784.25. See the computation below.
<h3>What is a circle?</h3>
Mathematically speaking, a circle is a 2-dimensional shape whose boundaries are round and are equidistant from a fixed center.
<h3>What is calculation of the answer given above?</h3>
The area of ΔPQR is given as ((√3)/4) x QR²
= (√3)/4) x (6√2 - 2√6)²
= 0.43301270189 x (8.48528137424 x 4.89897948557)²
= 0.43301270189 x 1728
Area of ΔPQR = 784.25

Answer:
y = -2x - 1 ; slope = -2, y-intercept = (0, -1)
Step-by-step explanation:
to get the slope and y intercept, you need to put the equation into slope-intercept form: y = mx + b
the term mx is the slope of the line, and b is the y-intercept
to do this, you need to solve for y, so get y by itself by subtracting 8x from the left side
8x + 4y = -4
-8x. -8x
4y = -8x - 4
divide both sides by 4 to get y alone
4y/4 = y
-8x/4 = -2x
-4/4 = -1
y = -2x - 1 is the final equation
the slope of the line is -2 (also can be said as -2/1), and the line intercepts the y-axis at (0,-1)
The acute angle is 3 degrees
