Answer:
its false
Step-by-step explanation:
Slope-intercept form: y = mx + b
m = the slope
b = y-intercept.
In this problem,
m = 3/5
b = ?
So far y = 3/5x + b
Let's plug the point (-3, -1) into our slope equation.
-1 = 3/5(-3) + b
Simplify the right side.
-1 = -9/5 + b
Add 9/5 to both sides.
4/5 = b
The equation is: y = 3/5x + 4/5
Answer choice A is correct.
Answer:
its a geometric sequence where each term is 3 times the previous term.
Step-by-step explanation:
{2,6,18,54,162,486,1458...}
X + 0.07x = 45; x = $42.06
if x is the basic price we must add 7% to this. As a fraction 7% is 7/100. As a decimal number this is 0.07, so the total to be paid is x + 0.07x (which can also be written as 1.07x). This must equal $45, so 1.07x = 45; divide both sides by 1.07 to get:
$42.06 to the nearest penny.
Hope this helps!
