Answer:
The slope is y=-x
Step-by-step explanation:
Rise over run. Pick 2 points, then count the distance that is rose(can be neg) then the distance that it went horizontally. Put into a fraction form.
Answer:
B. $79.45
Step-by-step explanation:
The equation for simple interest is I = PRT, where I = interest earned, P = principal/amount invested, R = rate as a decimal, and T = time in years.
For this example, we'll calculate the interest earned, then add to the principal to get the total amount of money in her account.
I = (70)(0.045)(3)
I = 9.45
70 + 9.45 = $79.45

Answer:
The transformation
maps triangle XYZ onto triangle X”Y”Z”.
Step-by-step explanation:
Let us take point Z on the XYZ triangle and see what sequence of transformations we have to apply to map it into the point Z''.
Now Z = (-2, 2) and Z'' = (-7, -1).
The x-coordinate goes from -2 ⇒ -7.
The y-coordinate goes from 2 ⇒ -1.
The x-coordinate is just shifted by -5; thus, 
, and the y-coordinate first transforms as 
, and is then shifted by 1; thus, it transforms as 
.
So we have the full transformation
Okay on here it has to deal with a certain theorem or postulate. The theorem states that the two angles opposite of the corresponding angle to the extended angle equal the extended angle. In other words the two given angles inside the triangle equal the outside angle so (62)+(7x+14)=15x-4
