Ratios are the same as fractions.
12:10 = 12/10
18:14 = 18/14
Divide.
12/10 = 1.2
18/14 = 1.2857
1.2857 > 1.2 ∴ 18/14 is greater

C' = (- 2, - 5 )
The line y = - 1 is a horizontal line passing through all the points with a y- coordinate of - 1
C= (- 2 , 3 ) and is 4 units vertically above y = -1 → (3 - (- 1))
The reflection will therefore be 4 units below y = - 1
- 1 - 4 = - 5 ← y-coordinate
The x- coordinate remains unchanged, thus
C' = (- 2, - 5 )
Answer:
The correct option is:
The student should have switched the direction of the inequality sign to get –5> x for a final answer
Step-by-step explanation:
The students has made a mistake in the 3rd step.
We know that when we multiply or divide any negative number on both sides of the inequality, the sign of inequality reverse its direction.
In step 3 the student divided 25 by -5 but did not switch direction of the inequality sign.
Therefore the correct option is: The student should have switched the direction of the inequality sign to get –5> x for a final answer....
Answer:
Step-by-step explanation:
Yoga Fun's price is represented by 65+12c where c represents classes.
Yoga For All's price is represented by 15c where c represents classes.
We notice that for the prices to be equal, 65+12c must equal 15c. This means that we take the difference, which shows that 65 must equal 3c. We divide to determine we must take 21.666... classes for the prices to be equal.
Answer:
x = 5.75
Step-by-step explanation:
4^(x+7) = 8^(2x-3)
But; 4^(x+7) = 2^2(x+7)
8^(2x-3) = 2^3(2x-3)
2^2(x+7) = 2^3(2x-3)
Since the bases are the same;
2(x+7) = 3(2x-3)
2x + 14 = 6x -9
14 + 9 = 6x - 2x
23 = 4x
x = 23/4
<u>x = 5.75</u>
