The cost, c(x), for a taxi ride is given by c(x) = 2x + 2.00, where x is the number of minutes.

A teacher had 24 red pen.if the ratio of red pens to blue pens she owned was 8:7, how many pens did she have total

Nat2105 [25]

Since it the ratio was 8:7
24 red pens=8, so 8 times 3 is 24. So 7 times 3 is 21. 21+24=45
Hope this helped <3

Answer:

B

Step-by-step explanation:

Area of a trapezoid = (1/2)*(base1+base2)*height

Area = (1/2)*(15+7)*height

DC is 7 which means EF is also 7.

AB = 15

AB - EF = AE + FB = 8

And AE = FB we know that AE is 8/2 = 4

We were given AD = 5. We have a 3-4-5 right triangle and therefore DE is 4. The height of the trapezoid is 3 ft.

Area = 1/2 (15+7)*(3)

Area = (1/2)*22*3

Area = 11 * 3

Area = 33 ft^2

Your answer is B

HELP PLEASE!!!!!!!!!!!

Answer:

Part 1) $y=-x^{2}$ ---> Translated up by 1 units

Part 2) $y=x^{2}+1$ ---> Reflected across the x-axis

Part 3) $y=-(x+1)^{2}-1$ ---> Translated left by 1 unit

Part 4) $y=-(x-1)^{2}-1$ ----> Translated right by 1 unit

Part 5) $y=-x^{2}-1$ ----> Reflected across the y-axis

Part 6) $y=-x^{2}-2$ ----> Translated down by 1 unit

Step-by-step explanation:

we know that

The parent function is

$y=-x^{2}-1$ ----> this is a vertical parabola open downward with vertex at (0,-1)

Calculate each case

Part 1) Translated up by 1 unit

The rule of the translation is

(x,y) -----> (x,y+1)

so

(0,-1) ----> (0,-1+1)

(0,1) ----> (0,0) ----> the new vertex

The new function is equal to

$y=-x^{2}$

Part 2) Reflected across the x-axis

The rule of the reflection is

(x,y) -----> (x,-y)

so

(0,-1) ----> (0,1) ----> the new vertex

The new function is equal to

$y=x^{2}+1$

Part 3) Translated left by 1 unit

The rule of the translation is

(x,y) -----> (x-1,y)

so

(0,-1) ----> (0-1,-1)

(0,1) ----> (-1,-1) ----> the new vertex

The new function is equal to

$y=-(x+1)^{2}-1$

Part 4) Translated right by 1 unit

The rule of the translation is

(x,y) -----> (x+1,y)

so

(0,-1) ----> (0+1,-1)

(0,1) ----> (1,-1) ----> the new vertex

The new function is equal to

$y=-(x-1)^{2}-1$

Part 5) Reflected across the y-axis

The rule of the reflection is

(x,y) -----> (-x,y)

so

(0,-1) ----> (0,-1) ----> the new vertex

The new function is equal to

$y=-x^{2}-1$

Part 6) Translated down by 1 unit

The rule of the translation is

(x,y) -----> (x,y-1)

so

(0,-1) ----> (0,-1-1)

(0,1) ----> (0,-2) ----> the new vertex

The new function is equal to

$y=-x^{2}-2$
