Answer:
y=2x+5
Step-by-step explanation:
u find the slope and since the y intercept is (0,5), that's the b value
hope this helps
Answer:
y=2/3x-9
Step-by-step Explanation
1.You put 2x-3y=6 into y-intercept to find out the slop, which is 2/3.
2. Put the coordinate pair given into point slop form, which will look like this: y+3=2/3(x-9)
3. Put that into y-intercept (answer)
4. Boom done
Answer:
0.015 m²
Step-by-step explanation:
Since we need the area in square meters, we need to first convert our centimeter values into meters.
1 · 10 = 10
10/100 = 0.1 m
1 · 15 = 15
15/100 = 0.15 m
The area of a rectangle is a = l · w. Plugging in the given values, we get:
a = 0.1 × 0.15
a = 0.015 m²

Answer:
- y-intercept: (0, -6)
- x-intercepts: (-3, 0), (-1, 0), (1, 0)
Step-by-step explanation:
We notice the first pair of coefficients is the same as the last pair (with the sign changed). This means we can factor by grouping.
f(x) = (2x^3 +6x^2) -(2x +6)
f(x) = 2x^2(x +3) -2(x +3)
f(x) = 2(x^2 -1)(x +3) = 2(x -1)(x +1)(x +3)
The factors are made to be zero when x is 1, -1, or -3.
The x-intercepts are (1, 0), (-1, 0), (-3, 0).
The y-intercept is the constant, -6.
If you type in both the coordinates it’ll give you the answer on google. That’s how I did this.
