(-4,1) and (-8,7)

write an equation in slope-intercept form

Answers

Answer 1

Answer:

y = -2x - 9

Step-by-step explanation:

so we have our two points, (-4,-1) and (-8,7) What we need to do to find our slope is y2 - y1 over x2 - x1. Once plugging in the numbers and subtracting it should give you 8/-4. 8 divided by -4 is -2. m = -2. Now to find our "b" we plug in our slope, and plug in one of the two points into the format of y = mx + b.

-1 = -2(-4) + b

multiply -2 and -4

-1 = 8 + b

we subtract 8 from itself and -1

-9 = b

Our equation is y = -2x - 9

How does the minimum or maximum value of a parabola relate to the vertex of the same parabola?

Answers

Answer:

The graph of a quadratic function is a U-shaped curve called a parabola. ... If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point on the graph, or the maximum value.

Step-by-step explanation:

please mark me brainlist

The relationship between the vertex and the minimum or maximum value of the parabola is given below.

What is a parabola?

A plane curve produced by a moving point such that its separation from a fixed point equals that of a fixed line is a parabola.

Let the vertex be any parabola is (x, y).

When the graph of the parabola opens up,

then the y-value of the vertex is the minimum value.

And when the graph of the parabola opens down,

then the y-value of the vertex is the maximum value.

Therefore, the explanation is given above.

The Garcia family started the day with 2 gallons of milk. They drank 111 quart of milk for breakfast and 3 pints for lunch.
How many pints of milk did the Garcia family have left after lunch?

Answers

3 pints

There are 8 pints of milk in 1 gallon. There is also 4 quarts in 1 gallon. So each quart is 2 pints.
After breakfast they had 3 quarts of the original gallon left since 4 - 1 = 3.
3 quarts is the same as 6 pints. They drank 3 pints at lunch. This means 6 - 3 = 3. After lunch, there were 3 pints left.

Answer:

m<R = 106°

Step-by-step explanation:

Given,

m<R = (6x+10)°

m<S = (2x+5)°

m<T = (3x-11)°

Now,

6x+10°+2x+5°+3x-11° = 180°{the sum of angles of triangle is 180°}

or, 11x+4° = 180°

or, 11x = 180°-4

or, x = 176°/11

or, x = 16°

therefore, x = 16°

m<R = (6x+10)°

= 6×16°+10°

= 96°+10°

= 106°

Write an equation of the line passing through point P(4,0) that is parallel to the line -x + 2y = 12.

Answers

arallel lines have the same slope
-x+2y=12
2y=x+12
y=(1/2)x+6
the slope is 1/2
using the point-slope form of a line...
y-y1=m(x-x1) where m is the slope and (x1,y1) is (4,0)
y-0=(1/2)(x-4)
y=(1/2)x-2 is the equation of the line
check: 0=(1/2)(4)-2
0=2-2
0=0
Answer: y= 1/2x-2
___________________
Explanation:

-x+2y=12
2y=12+x
divide both sides by 2
y= 6+ x/2
as they are parallel, therefore, their slopes are equal
hence,
put P(4;0) in the equation to find y intercept( y=kx+b, there b is y intercept)
0= 1/2 * 4+ b
b=-2
hence,
our equation is
y=1/2x-2

find the value of 3v - 10 given that -2v + 4 = 8​

Answers

Answer:

-16

Step-by-step explanation:

v=-2

I found this because since it is given that -2v+4=8; If v=-2 then the equation is true, because -2(-2) + 4 = 8. So since v=-2, plug in -2 into v of 3v-10; which would be (3(-2))-10, which is equal to -16.

I'm very glad I happened to be in the way, Alice said, as she helped her to put on her shawl again. The White Queen only looked at her in a helpless frightened sort of way, and kept repeating something in a whisper to herself that sounded like bread-and-butter, bread-and-butter, and Alice felt that if there was to be any conversation at all, she must manage it herself. So she began rather timidly: Am I addressing the White Queen? Well, yes, if you call that a-dressing, The Queen said. It isn't MY notion of the thing, at all. Alice thought it would never do to have an argument at the very beginning of their conversation, so she smiled and said, If your Majesty will only tell me the right way to begin, I'll do it as well as I can. But I don't want it done at all! groaned the poor Queen. I've been a-dressing myself for the last two hours. It would have been all the better, as it seemed to Alice, if she had got some one else to dress her, she was so dreadfully untidy. Every single thing's crooked, Alice thought to herself, and she's all over pins!may I put your shawl straight for you? she added aloud. I don't know what's the matter with it! the Queen said, in a melancholy voice. It's out of temper, I think. I've pinned it here, and I've pinned it there, but there's no pleasing it!
