Answer:
y = 3x + 1
Step-by-step explanation:
The formula for equation of a line in slope intercept form is;
y = mx + c
Where;
m is slope
c is y-intercept
Now, since we have coordinates, we will get the equation as;
(y - y1)/(x - x1) = m
(y - 1)/(x - 0) = 3
y - 1 = 3x
y = 3x + 1
Answer:
Yes
Step-by-step explanation:
Answer:
1.11,1.23,2.13, 3.12
Step-by-step explanation:
If it’s only 1.4x + 3.5y then that’s the answer because you can’t do anything with them. Since one has an x variable and the other has a y variable you can’t combine them together.
Answer:
Step-by-step explanation:
4.
a)
P = 2width + 2length
8x = 2x + 2 length; 8x-2x = 2 length; 6x=2 length
length = 3x
b)
sides= 1/4 of 3x = 3x/4
perimeter of square = 4* side = 4*3x/4 = 3x
c)
x= 4
P rectangle =8x= 8*4= 32
P square = 3x = 3*4 = 12
32-12 = 20 cm greater is the P rectangle than P of square
d)
A rectangle = 2x*x = 2*4*4 = 32
A square =(3x/4)² = (3*4/4)² = 9
32-9 = 23 cm² greater is the A rectangle than A of square
5.
4Comic+1 Nonfiction
4comic = 8y so 1 comic = 2y
1 nonfiction = (3+7y)+ 2y
a)
1 nonfiction = 7y+2y+3 = 9y+3
b)
total= 8y+9y+3 = 17y+3
if y=4
total = 17*4 +3 = $71
