Simplify (-7/8)(-3/4)
nirvana33 [79]
It would be 21/32. To find this out, you would need to first multiply (-7/8) by (-3/4) which would give you 0.65625. Then look at your answer choices and divide each one ( (/) = same as dividing) until you get 0.65625 as one of the values.

Match the information on the left with the appropriate equation on the right.
solmaris [256]

Answer:

Step-by-step explanation:

1). Equation of a line which has slope 'm' and y-intercept as 'b' is,

y = mx + b

If slope 'm' = 1 and y-intercept 'b' = -3

Equation of the line will be,

y = x - 3

x - y = 3

2). Equation of a line having slope 'm' and passing through a point (x', y') is,

y - y' = m(x - x')

If the slope 'm' = 1 and point is (-1, 2),

The the equation of the line will be,

y - 2 = 1(x + 1)

y = x + 1 + 2

y = x + 3

x - y = -3

3). Equation of a line passing through two points (x_1, y_1) and (x_2,y_2) will be,

y-y_1=\frac{(y_2-y_1)}{(x_2-x_1)}(x-x_1)

If this line passes through (-2, 3) and (-3, 4),

y-3=\frac{(4-3)}{(-3+2)}(x+2)

y - 3 = -1(x + 2)

y = -x - 2 + 3

y = -x + 1

x + y = 1

If the radius of a circle is 3.5 inches, its diameter is inches and its approximate area is square inches
alukav5142 [94]

diameter is radius x 2

3.5 x 2 = 7 inches


Area = PI x r^2

using 3.14 for PI

area = 3.14 x 3.5^2 = 3.14 x 12.25 = 38.465 square inches round answer as needed
