Answer:
-2
Step-by-step explanation:
The standard equation of a line is y = mx+c
m is the slope
c is the intercept
Given
Slope = -3
Get the intercept c;
Substitute m = -3 and (1, -9) into y = mx+c
-9 = -3(1) + c
-9 = -3 + c
c = -9 + 3
c = -6
The equation becomes
y = -3x + (-6)
y = -3x-6
f(x) = -3x-6
The zero of f occurs at f(x) = 0
0 = -3x-6
3x = -6
x = -6/3
x = -2
Hence the zero of the function is -2
Create 2 eq’n, let V = vans and B= buses
1. 150 = 8v + 14b
2. b + v = 15
isolate one variable and substitute it in to an equation:
b = 15 - v
sub “b” into first equation above:
150 = 8v + 14 ( 15 - v)
150 = 8v + 210 - 14v
-60 = -6v
10 = v
sub “v” into equation 2
b = 15 - v
b = 15 - (10)
b= 5
there will be 5 buses and 10 vans to hold 150 students.
The answer is 4:28.
1x4 equals 4.
7x4 equals 28.
Answer:
P-E-M-D-A-S
Step-by-step explanation:
Ok, so start with what i call "P-E-M-D-A-S"
P: parentheses | Also known as these: ( )
E: exponents | Its a small number by another number, like the 3 on your screen
M: Multiply | Also Known as x or a dot
D: Divide | i forgot how to make it
A: Add | also known as +
S: Subtract | also known as -
now go in order to solve it, it makes it much more easy!
