Mathematics

Drupady [299]3 years ago
4 0

Step-by-step explanation:

Scale factor is found by making a fraction of two numbers;

In this case, 3.5/2, since the dilated line is larger

Scale factor: 1.75 (simplified)

Given that QYprime is 4.125,

4.125 * (2/3.5)

= 2.357 (rounded)

Check whether (0, -2) is solution of the equation x - 2y = 4 or not.
Elan Coil [88]

Answer: Yes, it is a solution

===================================================

Explanation:

Any ordered pair, aka point, is of the form (x,y)

x is always listed first

The point (0,-2) means x = 0 and y = -2 pair up together

Let's plug them into the equation and simplify everything

x-2y = 4

0-2(-2) = 4

0+4 = 4

4 = 4

We end up with a true statement since we get the same thing on both sides, therefore the original equation is true for (x,y) = (0,-2)

(0,-2) is a solution to the given equation

Phrased another way: the point (0,-2) is on the line x-2y = 4. This point is the y intercept.

How many times greater is the value of 4 in 4735 than the value of the 4 in 6412
Andre45 [30]

Answer:

10 times

Step-by-step explanation:

Since the leftmost value is called ones place.

the second leftmost value is called tens place.

the third leftmost value is called a hundred place.

the fourth leftmost value is called a thousand place and so on.

So, The value of 4 in 4,735 is 4 thousand = 4,000

and the value of 4 in 6,412 is 4 hundred = 400.

Hence, the value of the 4 in 4,735 is 10 times the value of the 4 in 6,412.
