y=0x-3 because the slope is undefined, so it is 0 and the y intercept is -3 because it goes across the y axis.

Answer:

c = 1.45

Step-by-step explanation:

Solving the equation for c, we find ...

p +e = nc

c = (p +e)/n

Filling in the values given, we have ...

c = (4050 +300)/3000 = 4350/3000 = 1.45

The value of c is 1.45.

0.7x+6=0.3(4x+6)−2x

Gelneren [198K]

Answer: $x=-2.8$

Step-by-step explanation:

Given the following equation:

$0.7x+6=0.3(4x+6)-2x$

You can follow these steps in order to solve for "x" and find its value:

1. Apply Distributive property on the right side of the equation:

$0.7x+6=0.3(4x+6)-2x\\\\0.7x+6=1.2x+1.8-2x$

2. Subract $0.7x$ from both sides and add the like terms:

$0.7x+6-(0.7x)=1.2x+1.8-2x-(0.7x)\\\\6=-1.5x+1.8$

3. Subtract 1.8 from both sides:

$6-(1.8)=-1.5x+1.8-(1.8)\\\\4.2=-1.5x$

4. Finally, divide both side of the equation by -1.5:

$\frac{4.2}{-1.5}=\frac{-1.5x}{-1.5}\\\\x=-2.8$

What is the slope of the line shown below?

Nookie1986 [14]

It would be C because using the methof of rise over run, the change in x is 6 while the change in y is 17. So 14/6 woll get you 7/3.
