Are these equivalent?

Mathematics
1 answer:
dezoksy [38]3 years ago

Answer:

No

Step-by-step explanation:

The numerators must be multiplied by 2 to be equal, meanwhile the denominators must be multiplied by 44/21 to be equal.

Examples: 2.8/4.4 would be equivalent to 1.4/2.2. In turn, 1.4/2.1 would be equivalent to 2.8/4.2.

If Q(x,3) is a point on the line y= -2x+3. what are the coordinates of point Q?
cupoosta [38]
The point Q will satisfy the equation y=-2x+3 if the coordinates are plugged into the equation, so we plug in our known coordinate of the point Q (y = 3) and then we solve for x:
3 = -2x + 3
subtract 3 from both sides
0 = -2x
divide both sides by -2
x = 0
so the coordinate Q is (0,3)

Answer:

x = 2 and y = 5

Step-by-step explanation:

Given equations are :

y-x = 3  ......(1)

xy = 10 or

x = (10/y) ....(2)

Put the value of x in equation (1).

y-\dfrac{10}{y}= 3\\\\y^2-10=3y\\\\y^2-3y-10=0\\\\y=0\ and\ y=5

Put the value of y in equation (2).

x=\dfrac{10}{5}\\\\x=2

So, the value of x is equal to 2 and that of y is equal to 5.

If f(x) = x2 -1, what is the equation for f–1(x)?
Bess [88]
-1(1)=(2)-1 because you replace x with one since there is no number in front then you solve -1=-2 but make sure to multiply those four #'s

What is the missing expression? x^ 8 + 3x ^5 = x^5(_____)
JulsSmile [24]
What you are doing here is simply factoring out the GCF. In this example that factor would be x^5. Once that is complete the missing expression would be x^(3)+3. (also I like your profile picture)

Please, for me? I need to pass my math class.
Ede4ka [16]

Answer: Black

Step-by-step explanation: I feel like the higher the line is on the graph, the farther they have moved, so since the black line is the lowest, it might be Noah.

Hope this helps!
