Answer:

x = -1

Step-by-step explanation:

2(x + 3) - 4 = 0

2x + 6 - 4 = 0

2x + 2 = 0

2x = 0 - 2

2x = -2

x = -2 ÷ 2

x = -1

12. Dominic drives a taxi. He charges a $2 flat fee plus $1.50 per mile.

r-ruslan [8.4K]

Answer:

The y-intercept represents the flat fee.

Step-by-step explanation:

The y-intercept on the graph would be the point at which the line cuts across or intercepts the y-axis. At this point, the value of x (miles travelled) would be 0. The y-intercept in this case, would be the flat fee which is given as $2.

At x = 0, f(0) = 2.

The y-intercept represents the flat fee on the graph of f(x).

I NEED HELP ASAP PLZZZZ

KonstantinChe [14]

Step-by-step explanation:

We just subsitue 3 for x and -4 for y, so we get

$3(3) - 5( - 4) = 9 + 20 = 29$

$a = 29$

$7(3) + ( - 4) = b$

$21 - 4 = 17$

$b = 17$

Can Pie be Divided to make a Even Non-Decimal Number,if so what it it?

shusha [124]

Yes, if you divide it by fractions of pi, then you would get even integers.

$\frac{\pi}{\pi/2} = 2 \\ \\ \frac{\pi}{\pi/4} = 4 \\ \\ \frac{\pi}{\pi/N} = N$
