The expressions are not equivalent, even though Ella got the same result when she substituted zero for f. Then the correct option is C.

<h3>What is an equivalent expression?</h3>

The equivalent is the expressions that are in different forms but are equal to the same value.

Ella completed the following work to test the equivalence of two expressions.

First expression,                Second expression

⇒ 2f + 2.6                           ⇒ 3f + 2.6

⇒ 2(0) + 2.6                       ⇒ 3 (0) + 2.6

⇒ 0 + 2.6                           ⇒ 0 + 2.6.

⇒ 2.6                                 ⇒ 2.6

The expressions are not equivalent, even though Ella got the same result when she substituted zero for f.

Then the correct option is C.

The complete question is attached below.

Rewrite the equation y-3=2(x+4) into slope form
soldi70 [24.7K]

Answer:

Step-by-step explanation:

So we have y-3=2(x+4)

So the first thing we want to do is distribute the 2 in front of the (x+4)

2(x+4) = 2x+8

Which means we have:

y-3=2x+8

Remember we need to get it into the form y=mx+b

As you can see here the 3 is preventing our equation from being in that form to we need to add it to both sides. This leaves us with:

y - 3 + 3 = 2x+8+3

Which gives: y = 2x+11

Therefore the slope form of this equation is y = 2x+11

An access ramp to a building is 3.7 m long. The distance from beginning of the ramp to the base of the building is 3.5 m. How ta
hichkok12 [17]

Answer: 1.2 m

Step-by-step explanation:

Given

The length of the ramp to the building is 3.7 m

Distance from the beginning of the ramp to the base of the building is 3.5 m.

Suppose h is the height of the ramp

from the figure, we can write

\Rightarrow 3.7^2=3.5^2+h^2\\\Rightarrow 13.69-12.25=h^2\\\Rightarrow h^2=1.44\\\Rightarrow h=1.2\ m

So, the height of the ramp is 1.2 m

Given P(A) = 0.44, P(B) 0.6 and P(An B) = 0.394, find the value of
geniusboy [140]

Given:

P(A)=0.44,P(B)=0.6,P(A\cap B)=0.394.

To find:

The value of P(A\cup B), rounding to the nearest thousandth.

Solution:

We know that,

P(A\cup B)=P(A)+P(B)-P(A\cap B)

On substituting P(A)=0.44,P(B)=0.6,P(A\cap B)=0.394, we get

P(A\cup B)=0.44+0.6-0.394

P(A\cup B)=0.646

Therefore, the value of P(A\cup B) is 0.646.
