Answer:
the formula for surface area is 2(lb + bh + lh) sq is that helps :))
Step-by-step explanation:
9/3 = 3
3 exponent 3 = 27.
27 + 12 = 39
75 (7) = 525
<span>72 + 79 +74 + 76 + 76 + 75 = </span>452
525 -452 = 73
answer
<span>next round of golf she must shoot 73 in order to have an mean of 75</span>
Answer:
4) y = 9
5) x = -1
6) y = -5x − 9
Step-by-step explanation:
4) x = 3 is a vertical line with an x-intercept of (3, 0). It has an undefined slope.
A perpendicular line to that will be y = a, which is a horizontal line with a y-intercept of (0, a) and a slope of 0. Since this line passes through (3, 9), the equation of the line must be y = 9.
5) The y-axis is x = 0. A parallel line that includes the point (-1, -2) is x = -1.
6) Parallel lines have the same slope, so:
y = -5x + b
To find the value of b (the y-intercept), plug in the point (-2, 1):
1 = -5(-2) + b
1 = 10 + b
b = -9
y = -5x − 9
9/14 because 7+2 is 9 and 5+9 is 14
