Answer:
y -5 = -7(x +5)
Step-by-step explanation:
The point-slope form of the equation for a line is usually used for this purpose. For point (h, k), the line with slope m through it is given by ...
y -k = m(x -h)
Filling in the given numbers, you get the equation ...
y -5 = -7(x +5)
_____
This can be rearranged to any of several other forms:
y = -7x -30 . . . . . slope-intercept form
7x + y = -30 . . . . standard form
x/(-30/7) + y/(-30) = 1 . . . . . intercept form
Answer:
b. x=sin^-1(a/c)
c. x=tan^-1(c/a)
e. y=cos^-1(c/b)

There are 146 - 84 = 62 girls
ratio is 84:62
simplifies to 42:31
Answer:
Step-by-step explanation:
If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by π to get the diameter

Answer: $21.45
Step-by-step explanation:
FACTS:
1 yard costs $5.72.
She bought 3.75 yards
Total cost= cost per yard x number of yards
Total: t
t= 5.72x3.75
t= $21.45
She spent $21.45 for 3.75 yards of material
