Answer:
x=-16
Step-by-step explanation:
Subtract 4 from both sides
x+4-4=-12-4
x=-16
Answer:
4/11
Step-by-step explanation:
We can find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( 1 - -3)/(7 - -4)
= (1+3)/(7+4)
= 4/11
Answer:
1½ cords per hour
Step-by-step explanation:
A log splitter can split 6/5 cords of wood in 4/5 of an hour.
To find a unit rate, we divide the quantity of cords of wood by the time.
This gives us the complex fraction.

This is the same as

To divide two fractions, we multiply by the reciprocal of the second fraction.


This simplifies to:

The unit rate is 1.5 cords per hour
Answer:
The correct option is B.
Step-by-step explanation:
It is given that triangle A"B"C" is the image of triangle ABC after transformation.
From the given figure it is noticed that the point C lies on positive y-axis and point C" lies on negative x-axis.
It means the figure is rotated either counterclockwise 90° or clockwise 270°. The rotation rule is

The corresponding sides of image A"B"C" are smaller than the preimage ABC.

Since k<0, therefore the transformation shows the reduction. The dilation rule is




Option B is correct.
