Answer:
see the explanation
Step-by-step explanation:
we know that
If the absolute value of the scale factor is less than 1, then the dilation produces a contraction of the original image
If the absolute value of the scale factor is greater than 1, then the dilation produces an expansion of the original image
so
<u><em>Verify each value</em></u>
1) -4
therefore
The dilation produces an expansion of the original image
2) 0.25
therefore
The dilation produces a contraction of the original image
3) -2/3
therefore
The dilation produces a contraction of the original image
4) 2.3
therefore
The dilation produces an expansion of the original image
Answer: The answer is 1320 hope this is right.

Answer: The number is 7
Step-by-step explanation:
Let x be the [number]
<u />
<u>Rephrase the expression</u>
2 times a number is increased by 4, it is the same as 25 decreased by the number
2x+4=25-x
<u>Calculate</u>
Given
2x+4=25-x
Add x on both sides
2x+4+x=25-x+x
3x+4=25
Subtract 4 on both sides
3x+4-4=25-4
3x=21
Divide 3 on both sides
3x/3=21/3
x=7
Hope this helps!! :)

Answer:
The answer to number 1 is A.
Step-by-step explanation:
To find this answer, I made 1 1/3 into one big fraction. I multiplied the denominator by the whole number (3x1) and then added that product to the numerator. (3+1). The new fraction is now 4/3 (you keep the denominator the same). The next step is to multiply 4/3 by 3/8. When multiplying fractions, you multiply straight across (the numerator by the numerator, and the denominator by the denominator). Your answer is now 12/24. The final step is to simplify the answer. Since 12 is half of 24, the answer is 1/2.
