Explanation:The equation: 4x + 3y = -12
To plot the graph using the intercept, we need to find the y and x intercept
To get the y intercept, we replace x with 0
4(0) + 3y = -12
0 + 3y = -12
3y = -12
divide both sides by 3:
3y/3 = -12/3
y = -4
To get the x intercept, we will replace y with 0
4x + 3(0) = -12
4x + 0 = -12
4x = -12
divide both sides by 4:
4x/4 = -12/4
x = -3
Plotting the x and y intercept on the graph:
Answer:
Explanation is given below.
Step-by-step explanation:
Given:
Number of Trumpets = 40
Number of tubas = 35
Carlee says, the ratio of trumpets to tubas = 40 : 35
Danny says, the ratio of trumpets to tubas = 8 : 7
To explain why the two ratios are equivalent.
Solution:
Equivalent ratios are all ratios which are equal to each other in their reduced to simplest form.
The ratio of trumpets to tubas can be given as =
To reduce the ratio to its simplest form, we divide both numbers by their G.C.F.
The G.C.F. for 40 and 35 is 5.
So, we divide numerator and denominator by 5.
⇒
⇒
Thus, the simplest ratio of trumpets to tubas can be given as = 8:7
This is why both Danny and Carlee are correct with the ratios of trumpets to tubas.
Carlee gave the direct ratio, while Danny gave the simplest ratio.
