Answer:
27
Step-by-step explanation:
3x + 9 = 90
3x = 90 - 9
3x = 81
x =27
2(x-8)=7
Distribute on the left side
2x-16=7
Add 16 to both sides
2x=23
Divide both sides by 2
x=11.5
Final answer: The number is 11.5
Answer:
Below.
Step-by-step explanation:
1) 245.
2) Approximate slope = -(245-200)/15 = -3.
Answer:
Step-by-step explanation:
We do not have enough information for slope intercept form. But we can use the point-slope formula to find the information. The formula is where we substitute a point (x,y) for .
We know it is parrallel to the listed line in slope intercept form. Recall, y=mx+b tells that the m is slope. Since y=6x-1, then m=6. We also have a point for the new line (-3, 4). We input m and .
We now simplify the parenthesis and solve for y.
We add 4 to both sides to isolate y,
This is slope intercept form. The line as slope 6 and y-intercept (0,22) or b=22.
