Three ordered pairs would be
x y
0, -15
1, -12
2, -9
ect...
Let the first digit of the 2-digit number be x and the second digit be y.
Then the ratio (x/y) equals (1/2). Write a formula for y in terms of x.
The tens digit is 2 more than the units digit. Using the letters x and y, write out the proper equation.
Now solve your two equations simultaneously for x and y.
Answer:
x>=-12
Step-by-step explanation:
3x+7>=-29
3x>=-29-7
3x>=-36
x>=-36/3
x>=-12
Answer:
y=-3
Step-by-step explanation:
If the line is parallel to the x-axis then it is a horizontal line with slope 0. These lines have form y=b where b is the y-intercept or y value of all points. y=-3 is the line since (2,-3) is on the line.
Answer for 4a. 25(n + 6)
Reason
The product (means to multiply)
Six more than a number (n + 6)
And 25 (other multiplier)
Expression is 25(n+ 6)
