Which expressions are equivalent to -90-60w

Answer:

Two algebraic expressions are equivalent if they always lead to the same result when you evaluate them, no matter what values you substitute for the variables. For example, if you substitute x := 3 in x + x + 4, then you get 3 + 3 + 4, which works out to 10; and if you substitute it in 2x + 4, then you get 2(3) + 4, which also works out to 10.

Step-by-step explanation:

Which expressions are equivalent when m = 1 and m = 4? 5 m minus 3 and 2 m 5 m 3 m 4 and m 4 2 m 2 m 7 and 3 m minus 3 m 5 m 3 a
emmasim [6.3K]

The expressions that are equivalent when m = 1 and m = 4 is;

Option B: 3m + 4 and m + 4 + 2m

We are given m = 1 and m =4;

A) 5m - 3 and 2m + 5 + m

B) 3m + 4 and m + 4 + 2m

C) 2m + 7 and 3m - 3 + m

D) 5m + 3 and 4m + 2 + 2m

For option B; 3m + 4 and m + 4 + 2m

Let's put m = 1

3(1) + 4 = 7

Also, 1 + 4 + 2(1) = 7

Similarly, let us put 4 for m to get;

3(4) + 4 = 16

Also, 4 + 4 + 2(4) = 16

In both cases, the expressions are equivalent and as such option B is the right one.

An object be a moving at the starting (0,0) on the graph. Average speed in miles per hour of the object for an entire trip five
Vikki [24]

Answer: 17 miles per hour.

Step-by-step explanation:

1. To solve this problem you must apply the following formula:

S=Δx/Δt

Where Δx is the position variation and Δt is the time variation.

2. Then, based on the graph shown attached, you have:

S=\frac{20mi+20mi+30mi+15mi}{1h+1h+1h+2h}

3. Therefore, you have that the result is:

S=17mi/h

Let f(x) = x + 8 and g(x) = x2 − 6x − 7. Find f(g(2)). (1 point)
pantera1 [17]
Hello,

f(x)=x+8
g(x)=x²-6x-7
f(g(x))=f(x²-6x-7)=x²-6x-7+8=x²-6x+1

f(g(2))=2²-6*2+1=4-12+1=-8+1=-7
