Which equation represents a line which is parallel to the line 7x - y = 4?

koban [17]

Answer:

Step-by-step explanation: step : Place the given line’s equation in slope- intercept form y = mx + b. A line parallel to this line will have the same slope.

7x - y = 4. Yields y = 7 x - 4. Therefore y = 7x - 5 is the correct answer.

Need help please. Thanks so much.

Answer:

$(-1,\frac{17}{6})$

$(3,\frac{3}{2})$

$(-5,\frac{25}{6})$

Step-by-step explanation:

The given equation is $2x+6y=15$

We substitute the ordered pairs to see which ones satisfies the equation.

For (-1,-8), we put x=-1 and y=-8 to get:

$2(-1)+6(-8)=^?15$

$-2+-48=^?15\\-50=^?15$

This is not true.

For $(-1,\frac{17}{6}))$ we put x=-1 and $y=\frac{17}{6}$ to get

$2(-1)+6*\frac{17}{6})=15\\ -2+17=15\\15=15$

This is true

For (3,3/2) we have 2(3)+6(3/2)=15

This implies 6+9=15

15=15

This is also True

For (-5,25/6), we have 2(-5)+6(25/6)=-10+25=15

This is also true.

krek1111 [17]

Answer:

f(-2) = 20

Step-by-step explanation:

f(x) = 2x² - 3x + 6

f(-2) = 2(-2)² - 3(-2) + 6

= 2(4) + 6 + 6

= 8 + 12

= 20
