If you graph 2y+8=6x^2-10x what will be the y intercept?
Rufina [12.5K]

Answer:

Y intercept will be -4.

Step-by-step explanation:

Here we are given our function as

2y+8=6x^2-10x

We are asked to determine the y intercept.

The y intercept is the y ordinate of the coordinates of the point at which the graph of the function intersects the y axis.

Please note that the point at which graph cuts the y axis have x=0

Hence in order to determine y intercept we need to put x=0 in our function and solve it for y :

2y+8=6x^2-10x2y+8=6x^2-10x

Putting x =0

2y+8=6x^2-10x2y+8=6(0)^2-10(0)

2y+8=6x^2-10x2y+8=0-10(0)

2y+8=6x^2-10x2y+8=0

subtracting both sides by 8

2y+8=6x^2-10x2y=-8

dividing both sides by 2

=-4

Evaluate the expression. 1/2 - 4 (1/2 + 1)^2
insens350 [35]

Answer:

D. -17/2

Step-by-step explanation:

1/2 - 4 (1/2 + 1)^2

First we evaluate what is inside the parentheses

1/2 - 4  (3/2) ^2

Now we square what is inside the parentheses

1/2 - 4(9/4)

Now multiply

1/2 -9

Get a common denominator  9 = 9 *2/2 = 18/2

1/2 - 18/2

-17/2

12men or 18women can reap a field in 14 day ,8man and 16women can reap the same field in​
melisa1 [442]

Answer:

Step-by-step explanation:

12 men and 18 women: x1; 14 days; y1

8 men and 16 women: x2; ?; y2

12/18 simplified is equal to 2/3

8/16 simplified is equal to 1/2

This is a direct proportion, thus we can say that:

(1/2*14)/(2/3)=y2

7/(2/3)=10.5 days

I hope this helped you get out of homework trouble :D

Write an equation of the line that passes through (9, 2) and is parallel to the line below
Alex777 [14]

Answer:

y=5/3x-13

Step-by-step explanation:

We must use the point-slope form(parallel lines have the same slope, remember that!)

y-y1=m(x-x1)

y-2=5/3(x-9)

y-2=5/3x-15

y=5/3x-13
