The sum of two numbers is 89. Four times the first number plus the second number gives 155. What are the two numbers?
Let the first number equal x and the second number equal y. You have: A) x + y = 89. B) 4x + y = 155. First you rearrange equation A to obtain equation C) y = 89 - x Then substitute C) into B) to obtain equation D) 4x + 89 - x = 155 Solve equation D) for x to obtain x = 22. Place the value of x in equation C) to obtain y = 67. Thus your answer is {x = 22, y = 67}.
How do you find y-intercept?
The y-intercept can be obtained from the straight line formula, y=mx+c. The y-intercept, c, is therefore given by c=-mx+y where m is the coefficient of gradient.
Can you write an equation for a non proportional linear relationship?
Yes. y = mx + c where m and c are non-zero constants.Yes. y = mx + c where m and c are non-zero constants.Yes. y = mx + c where m and c are non-zero constants.Yes. y = mx + c where m and c are non-zero constants.
Y equals mx plus c what is m and c?
well, m is the slope and c is the y-intercept
What is the equation for y varies directly as the cube of x?
y = c*x3 where c is the constant of proportionality.

What equation has a graph parallel to the graph of 9x plus 3y equals -22?
3x + y = c where c is any constant number of your choice.
What is 22 equals C?
The answer to 22 = c is c = 0, as shown below. 22 = c multiply both sides by c 22c = c^2 subtract 484 from both sides 22c - 484 = c^2 - 484 factor 22(c - 22) = (c-22)(c+22) dived both sides by c - 22 22 = c +22 subtract 22 from both sides 0 = c
Find two numbers whose sum is 35 and whose difference is 9?
start with what you know: x + y = 35 x - y = 9 add them together: x + x + y - y = 35 + 9 resolve the rest of the facts: X + X = 44 X = 22 22 + y = 35 22 + y - 22 = 35 - 22 y = 13 confirm: 22 + 13 = 35 22 - 13 = 9

What is y when 198-22y equals 220?
198-22y = 220 -22y = 220-198 -22y = 22 y = 22/-22 y = -1
