Answer:

c. -17

Step-by-step explanation:

We have the function f(x) = -2t^2 + 1 and we need to solve for x if f(-3).

Substitute the x in the function with the x in the equation :

f(-3) = -2(-3)^2 + 1

Solve for the answer :

f(-3) = -2(9) + 1

f(-3) = -18 + 1

f(-3) = -17

Therefore, c. -17 is the answer.

In triangle EFG , EF=FG . EF= 6X-10 , EG =2X+14, and FG =3X+11. find EF .

jarptica [38.1K]

Since EF=FG, you can set 6x - 10 = to 3x + 11

$6x -10 = 3x +11$

Then add like terms

$6x - 3x = 11+10$

so, $3x = 21$

Now you can divide by 3 to get $x = 7$ :)

then put it back into $6x - 10$

$6(7) - 10 = EF$

so, $EF = 32$

Draw a line from each figure to an area

Georgia [21]

Answer:

A=27 cm^2

B=24 cm^2

C=26 cm^2

D=28 cm^2

Step-by-step explanation:

Break each problem down into individual shapes.

For instance, A can be split into a 3 by 3 square and a 6 by 3 square.

Get the area by multiplying the length & height: A = L * H

For the triangles the area is the same equation divided by 2 A=LH/2

Shapes with unclear dimensions like C can be skipped and have their area revealed through process of elimination.

Shawna reduced the size of a rectangle to a height of 2 in. What is the new width if it was originally 24 in wide and 12 in tall

miskamm [114]

Answer:

4 inches.

Step-by-step explanation:

The height of a rectangle is reduced by Shawna to a size of 2 inches.

The original width of the rectangle was 24 inches and the height was 12 inches.

If the ratio of width to height remains the same, then we can find the new width.

If the new width is x inches then, we can write

$\frac{x}{2} = \frac{24}{12}$

⇒ x = 4 inches. (Answer)
