Gradient= -2
Y intercept= 1
Answer: y= -2x + 1
Answer:
Step-by-step explanation:
area = length x breadth
length = 5 inches greater than width = 5+x
width = x
area = (5+x) x
104 = (5+x) x
104 = 5x + x²
x²+5x-104 =0
looking for two numbers that when you multiply gives 104, and adding it gives +5
the numbers is 13 and 8 (-13, +5)
x²+5x-13x-104 =0
x(x+5)-13(x+5) = 0
(x+5)(x-13)=0
x+5 =0 x-13 =0
x = -5, x=13
x= -5, 13
the width is either -5 or 13 inches
the length = (5+x) = (5+(-5)) = 5-5 =0
(5+x) = (5+13) = 5+13 = 18
lenth is 0 or 18 inches
Answer:
7.5 cm: 30 cm
Step-by-step explanation:
The scale is 1 cm: 4cm which is 1/4. The next one would be 7.5 cm: 30 cm because that is also equal to 1/4.
Answer:
Step-by-step explanation:
- Apply the distributed property, so it now looks like this: -3n + -18 + 10 = -9
- Combine like terms: -3n + -8 = -9
- Simplify: -3n - 8 = -9
- Add 8 to each side, so it now looks like this: -3n = -1
- Divide each side by -3 to cancel out the -3 next to n. It should now look like this: n = 1/3
I hope this helps!
