Mathematics
1 answer:
Hitman42 [59]3 years ago
6 0

Step-by-step explanation:

2:3 and 4:6 is proportional because if you simplify 4:6 it will equal 2:3.

1:4 and 6:18 is not proportional because if you simplify you would not get 1:4.

3:5 and 1:3 is not proportional because you can't simplify it any further and they do not equal each other.

2:5 and 8:20 is proportional because if you take 2:5 and multiply each number by 4 you would get 8:20.

4:9 and 12:27 is proportional because you can simplify 12:27 and get 4:9.

6:15 and 2:5 is proportional because you can multiply 2:5 by 3 and get 6:15.

If f(x) =x^2 + 4x and g(x) = 2x +4, find (fg)(1)
snow_lady [41]

Step-by-step explanation:

Set up the composite result function.

f(g(x))f(g(x))

Evaluate f(g(x))f(g(x)) by substituting in the value of gg into ff.

f(x2)=2(x2)−4f(x2)=2(x2)-4

Multiply 22 by x2x2.

f(x2)=2x2−4f(x2)=2x2-4

Consider this algebraic expression:     –3x + x + 5 Use the algebra tiles to model the expression.
luda_lava [24]

For this case, we have the following expression:

-3x + x + 5

We simplify the expression:

If we add similar terms, taking into account that different signs are subtracted and the sign of the greater one is placed, we have that -3x + x = -2x

So, we have to:

-3x + x + 5 = -2x + 5

Answer:

-3x + x + 5 = -2x + 5

Do you think any ordered pairs are solutions to BOTH y=x+5 and y=-2x-1? Explain.
Rina8888 [55]

Answer:

ordered pair(-2 , 3) is the solution

Step-by-step explanation:

y=x+5

y=-2x-1

x+5 = -2x-1    substitution

x+5+2x-5 = -2x-1+2x-5

3x = -6

x = -2

y = -2+5 = 3

ordered pair(-2 , 3) is the solution
