Let the weight of Paula's dog be x
Let the weight of Carla's dog be y
We know that the weight of Paula's dog is 3 times that of Carla's dog, therefore:
x = 3y ...........> equation I
We also know that the sum of the weights is 48 pounds, therefore:
x + y = 48 ............> equation II
Substitute with equation I in equation II:
3y + y = 48
4y = 48
y = 12 pouds
Substitute with the value of y in equation I:
x = 3(12) = 36 pounds
Based on the above calculations:
Paula's dog weighs 36 pounds
Carla's dog weighs 12 pounds
Answer:
C: {−5, 1)
Step-by-step explanation:
Starting with −2|−2x−4|=−12, divide both sides by -2:
|−2x−4| = 6
Reduce this by dividing all terms by 2:
|-x - 2| = 3
This is equivalent to x + 2 = 3 and x + 2 = - 3
Solving thse two equations, we get x = 1 and x = -5
And so the solution set is C: {−5, 1)
Answer:
The standard form of a parabola is
y=ax2+ +bx+c, where a≠0.
To find the vertex, you need to find the x- and y-coordinates.
Answer:
slope = -7
Step-by-step explanation:
(1, 4) and (2, -3)
Slope = y^2 - y^1 / x^2 - x^1
m = -3 - 4 / 2 - 1
m = -7 / 1
m = -7 ---------> slope of the line through (1, 4) and (2, -3)
