The graph of the linear equation can be seen in the image below.

Here we have the linear equation:

y = -4x + 8

And we want to find 3 ordered pairs, to do so, we need to evaluate x in different values.

if x = 0 then:

y = -4*0 + 8 = 8

So we have the ordered pair (0, 8).

if x = 1 then:

y = -4*1 + 8 = 4

Then we have the ordered pair (1, 4)

If x = 2 then:

y = -4*2 + 8 = 0

Then we have the ordered pair (2, 0).

Now that we have these 3 ordered pairs, we can graph them in a coordinate axis and then connect them with a line, we will get something like the graph below.

That is the graph of our linear equation:

Answer:

a.  y + 3 = 0

Step-by-step explanation:

x-axis has slope of 0 so any lines parallel to x-axis has slope of 0

With m = 0 , x = -4, y = -3

y = mx + b

-3 = (0)(-4) + b

b = -3

so y = -3

or y + 3 = 0

The value of the function f(-4) = 16.

A function is categorized as a relationship between a set of inputs that each have one output.

For the given function in the question;

f(x) = x ² , if  x < 0.

f(x) = 0 , if  x = 0.

f(x) = 2x + 1 , if  x > 0

Now, estimate the values;

(a) f(-4)

As, the value of the x to be substitute is negative, the function used will be.

f(x) = x ² ,for  x < 0.

Put the value x = -4

f(-4) = (-4)²

f(-4) = 16

The value of f(-4) = 16.

(b) f(0)

As the value of function is zero.

Then,

f(x) = 0 , if  x = 0.

Put x = 0 in function we will get.

f(x) = 0.

(c) f(2)

As the value to be substituted is positive, the function used is;

f(x) = 2x + 1 , if  x > 0

Put x = 2

f(2) = 4 + 1

f(2) = 5

Thus, the value of f(2) is 5.

the distance between Point A (-8,-2) and Point B(6,-1) in Radical form= [tex]\sqrt{197}[/tex]

Distance formula:
The distance between two points formula uses the coordinates of two points in space. In coordinate geometry, the distance between two points can be calculated using the distance formula, present in a two-dimensional or three-dimensional space. The distance formula for two points is also an application of the Pythagoras theorem

the distance formula is used to find the distance between any two points when we already know the coordinates. The points could be present alone on the x-axis or y-axis or on both axes.

Let us consider, that there are two points say A and B in an XY plane. The coordinates of point A are (x1,y1), and of B are (x2,y2). Then the formula to find the distance between two points PQ is given by:

AB=[tex]\sqrt{(x2-x1)^{2} +(y2-y1)^{2} }[/tex]

Note: If the coordinates of two points P and Q are such that, (x1, 0) and (x2, 0), the distance between PQ will be given by:

PQ = |x2 – x1|

the distance between point origin O(0,0) and P(x,y) is given by:

OP = √((x2 – 0)² + (y2 – 0)²)

OP = √((x2)² + (y2)²)

or simply,

OP = √(x² + y²)

Solution :

where x and y are coordinates of points other than the origin.

Given :

(x1,y1) = (-8,-2)

(x2,y2)= (6,-1)

Solution:

[tex]d=\sqrt{x^{2} +y^{2} } \\d=\sqrt{(6+8)^{2} +(-1+2)^{2} } \\d=\sqrt{14^{2}+1^{2} } \\[/tex]

Answer: 39 ounces of strawberry juice, 78 ounces of water.

Step-by-step explanation:

Since Molly uses "each ounce" meaning 1 per strawberry juice, 39 ounces of strawberry infused water would mean she uses 39 ounces of strawberry juice. Then, it says she uses two times as many as those 39 ounces of strawberry juice for water. This means you multiply 39 by 2 which means you get 78 ounces.

Molly uses 39 ounces of strawberry juice and 78 ounces of water to get 39 ounces of Strawberry Infused Water.

Answer:  Choice 2

invalid. The inner circle is plants, and the outer circle is those with cells.

=========================================================

Further Explanation:

If we throw a dart at random, and we land in the inner circle (plants), then we automatically land in the outer circle (has cells).

Now imagine the dart landed in the "has cells" circle, but outside the smaller circle. This could be stuff like animal cells, bacteria, etc. So just because something has cells it does not automatically make it a plant. Saying "an iris has cells" is not enough info to be able to tell it's a plant or not. This means the conclusion of "irises are plants" is shaky at best.

This is why the overall argument structure is invalid.

We know that we could be able to obtain the equation by the use of the equation is a straight line. The general form of the equation of a straight line is given as y = mx +c

The first thing that we must do is to obtain the slope of the graph from;

m = y2 - y1/x2  x1

m = 45 - 15/6 - 2

m = 7/2

The graph begins at origin hence c = 0

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the structure and/or location of the object.

The reflection does not change the shape and size of the geometry. But flipped the image.

The triangle ΔXYZ is reflected across the line AB to get the tringle ΔX'Y'Z'.
