No,
5x means 5 is being multiplied by a number (x)
x+5 means that’s a number (x) is being added to 5
Hope this helps ;)
Answer:
Step-by-step explanation:
slope of line perpendicular to y=mx+c is -1/m
so here reqd. slope=-1/4
Answer:
x = -20/11
Step-by-step explanation:
and how -(11 x)/4 - 5 = 0
1/4 (7 x - 12) = 1/2 (9 x + 4)
hope this helps
when you get this kind of exercise, you just need to check which equations resemble the graph
A. y= 6-4x
y= -4x+6
B. y= -4x+8-2
y= -4x+6
C. y= -4x-8-1
y= -4x-9
D. y= -4x+6
-> A, B and D are the same equations
-> the easiest way to find which graph is correct (A/B/D OR C), is to create the graph yourself using the drawn graph:
y= ax+b
a= negative (the line goes down)
to find the a you go 1 step to the left and look which point of the graph has the same x. in this exercise it's when y=4
a=-4
b= the y-coordinate of the point where the graph cuts the y-axis.
b=6
-> graph shown in picture is y= -4x+b
-> graph A/B/D is correct
-> C is does not represent this line
Set up an equation that models the problem:
46 * x = 423, where x is the number of lawns he needs to mow.
then x = 423/46 = 9.19
Round up to 10 lawns.
