Answer:
6 Pies
Step-by-step explanation:
So you know that there were 70 pies in total. Each pie has 7 pieces. To get the number of pies, you can say the number of pies is X.
The equation would be 7x=70.
Divide 7 from both sides:
x=10
That means there are 10 pies in total.
I the question, it says that the cafeteria donated 4 pies.
To get the number of pies that the club made, subtract 4 from 10, gettin g6.
That means the club made 6 pies.
We use quadratic formula for that one
remember that √-1=i
so
for
ax^2+bx+c=0
so
given
1x^2+5x-5=0
a=1
b=5
c=-5
solutions:
Step-by-step explanation:
Equation of straight line is y=mx+c
choose any two points on straight line
for me I choose:(-3,11) and (3,-1)
use these two points to find gradient,m.
m= (-1-11)/(3-(-3))
m= -2
now, y=-2x+c
choose any point on the straight line
I choose point (3,-1)
sub the point into the equation to find c
-1=-2(3)+c
c=5
equation: y=-2x+5
Step-by-step explanation:
y= -7x-6
for y-intercept x=0
y= -7 (0)-6
y = 0-6
y = -6
y-intercept (0,-6)
for x-intercepy y=0
0= -7x-6
-7x=6
x= -0.86
x-intercept (-0.86,0)
