So,...
the slope intercept form is y = mx+b
the m is the slope, and the b is the coordinate that intercepts the y-axis
so to start you off, 4x - 9y = 2
4x - 9y = 2
-4x - 4y
-9y = -4y +2
divide both sides by -9
<u>-9y </u>= <u>-4y + 2</u>
-9 -9
y = 4/9 x - 2/9
Answer:
-15 and 0
Step-by-step explanation:
-15 + 15= 0
t = 5 + 3m is the required expression that represents weight of Tony fish
<h3><u>Solution:</u></h3>
Let "t" represent the weight of Tony’s fish, and let "m" represent the weight of Mary’s fish
To find: expression that represents the weight of Tony's fish
According to given information,
Tony’s fish weighs five pounds more than three times the weight of Mary’s fish
Here the word "times" represents multiplication and "more than" represents addition
Weight of Tony fish = 5 + three times the weight of Mary’s fish
Weight of Tony fish = 5 + 3(m)
t = 5 + 3m
Thus the required expression is found out
Answer:
The test contains 10 three-point questions and 14 five-point questions
Step-by-step explanation:
Given equations are:
From 2nd equation we can deduce that x represents number of 3-point questions and y represents number of 5-point questions.
Using the substitution method:
From x+y = 24
y= 24-x
Putting this valu of y in 3x+5y=100
Hence, the correct answer is:
The test contains 10 three-point questions and 14 five-point questions..
Answer:
y=-3/4x+3
Step-by-step explanation:
the slope is -3/4
in this case, y=mx+b
so y=-3/4x+b
b is the y intercept, so it would be 3
altogether, y=-3/4x+3
