For what value of a is -√a < - 1/-√a 2 ⅓ 1 0

Move options to the blanks to define the transformations that can be done on C1 to show that it is similar to circle C2.

katrin [286]

Answer:

Circle C1 can be dilated at its center by a scale factor of 1/2. Then the image can be translated left 4 and down 6. This will map circle C1 onto circle C2 and prove they are similar.

The graph depicts the growth and costs using of line segment use the midpoint formula to approximate the cost during the year 19

marysya [2.9K]

Answer:

The approximate cost during the year 1987 was $7,533

Step-by-step explanation:

The complete question in the attached figure

we have

y -----> is the cost in dollars

x -----> is the year

Looking at the graph we have the points

(1983,5,047) and (1991, 10,019)

To determine the cost in the year 1987, find out the midpoint between the two given points

The formula to calculate the midpoint between two points is equal to

$M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

substitute the values

$M=(\frac{1983+1991}{2},\frac{5,047+10,019}{2})$

$M=(1987,7,533)$

therefore

The approximate cost during the year 1987 was $7,533

Solve solve the following equations 2x (x minus 5) close + 3(x-2)=8+7(x-4)

stiv31 [10]

Step-by-step explanation:

2x(x-5)+3(x-2)=8+7(x-4)

2x²-10x+3x-6=8+7x-28(Group like terms)

2x²-10x+3x-7x=8-28+6

2x²-7x-7x=-20+6

2x²-14x=-14(Divide both sides by -14)

2x²-x=1

2x=1

x=½

Hope you get it please someone should verify....
