For this case we have the following expression:

$14 + 3x - 7 = 7x + 7 - 4x$

To answer the question, what we must do is rewrite both sides of the equation.

For this, we apply the associative property.

We have then:

$3x + (14-7) = (7x-4x) + 7$

Rewriting we have:

$3x + 7 = 3x + 7$

Since both sides of the equation are equal, then the expression is always true.

Answer:

A) Always

What does x equal to

Slav-nsk [51]

If that is a rhombus as it says it is, then the diagonals are perpendicular to one another, meaning where they meet, they form right angles. Therefore, angle x is a 90 degree angle.

A graphic designer wants to translate rectangle DEFG using T–1, 2(x, y). The pre-image has coordinates D(–1, 3),

anygoal [31]

Answer:

D'(-2, 5), E'(3, 5), F'(3, 3), G'(-2, 3)

Step-by-step explanation:

Adding (-1, 2) to each of the coordinates gives ...

D +(-1, 2) = (-1-1, 3+2) = D'(-2, 5)

E +(-1, 2) = (4-1, 3+2) = E'(3, 5)

F +(-1, 2) = (4-1, 1+2) = F'(3, 3)

G +(-1, 2) = (-1-1, 1+2) = G'(-2, 3)

Which linear function has a negative slope, f(x) or g(x)?

Anit [1.1K]

Answer:

f(x) is negative and g(x) is positive

Step-by-step explanation:

f(x) = 4-x

Rewriting

f(x) = -x+4

We recognize this as

y= mx+b or the representation of a line with slope -1 and y intercept 4

f(x) is linear

g(x) as we increase x by 1 we increase g(x) by 2

The slope is 2, and the y intercept is 1

y = 2x+1

Lets check a point

(2,5)

5 = 2(2)+1

5=5 so we are correct

f(x) is negative and g(x) is positive

Use a net to find the surface area of the right triangular prism shown:

erma4kov [3.2K]

Answer:

256 ft²

Step-by-step explanation:

Net comprises: 2 equal triangles, 2 equal rectangles and 1 smaller rectangle

Area of a triangle = 1/2 x base x height

⇒ area of one triangle = 1/2 x 10 x 7 = 35 ft²

Area of a rectangle = width x length

⇒ area of larger rectangle = 6 x 12 = 72 ft²

⇒ area of smaller rectangle area = 6 x 7 = 42 ft²

⇒ Total area = (2 x 35) + (2 x 72) + 42 = 256 ft²
