Answer:
A. y=-0.5x-2.5
Step-by-step explanation:
To figure out the equation of a line, use the formula y=mx+b, where x and y are the co-ordinate values, m is the slope and b is the y-intercept (where the line cuts the y-axis).
The slope, m, is calculated by dividing the y-difference (in this case, -2.5) by the x-difference (5): -2.5/5 = -0.5
From the diagram, we can see the line cuts the y-axis at (0,-2.5). Therefore b=-2.5
Sub in our values to get: y=-0.5x-2.5
Answer:
$150.00
Step-by-step explanation:
Tenía $ 5.00
Mi mamá me dio $ 10.00 mientras que mi papá me dio $ 30.00.
Esto significa que luego tengo:
5 + 10 + 30 = $ 45.00
Mi tía y mi tío me dieron 100.00.
Entonces tuve:
45 + 100 = $ 145.00
Tenía otros $ 5.00.
Esto significa que en conjunto tuve:
145 + 5 = $ 150.00
3(x+4)=1/2x-8 that's your original equation. If you read through the problem as you look at my work, you will see it matches up as you read it out loud and see my equation.
to solve, first distribute.
3x+12=1/2x-8
next you need to subtract 1/2x from both sides. this is using the identity property of addition.
2.5x+12=-8
next, subtract 12 from both sides. this demonstrates the identity property of subtraction.
2.5x=-20
next, divide by the coefficient of x (which is 2.5) to find the value of x, your variable.
x=8. you're done. hope this helped :)
