Answer:
<em>y</em> = $1 + $2<em>x</em>
Step-by-step explanation:
The one dollar represents the amount of the party alone. The two dollars multiplied by the x gets you how much money will be spent towards guests altogether. Adding these gets you the total cost. (FYI - I put the dollar sign, but you may not need it.)
Step-by-step explanation:
Answer:
y = 3/4x + 2
Step-by-step explanation:
y = mx + c is the formula to find the equation
to find a equation we should have a point and a gradient ( m )
now, point = (4 , 5) m = 3/4
then we sub the point and the gradient (m) into the equation formula
y=mx + c
5 = 3/4 (4) + c
5 = 3 + c
5 - 3 = c
2 = c
c = 2
now we rewrite the equation become y= 3/4x + 2
Answer:
x = 2.5
Step-by-step explanation:
Answer:
first number= 19/5
second number= 2/5
Step-by-step explanation:
first number= a
second number= b
a+3b=5 equation 1
b+2a=8 equation 2
using equation 2 we have
b=8-2a
using equation 1 we have
a+3(8-2a)=5
a+24-6a=5
24-5=6a-a
19=5a
a=19/5 = first number
so using b=8-2a
we have
b=8-2(19/5)
b=8-(38/5)
b=2/5 = second number
