In health class, Jason is learning about making healthy food choices. For a lesson on digestive health, his teacher asks everyone to track how much fiber they eat daily. At breakfast, Jason has a banana. He also has raisin bran cereal, which contains 3.6 grams of fiber. In all, Jason eats 6.9 grams of fiber at breakfast.
Use an equation to find the amount of fiber in the banana.
The amount of fiber in the banana will be 3.3 fibers.
How to calculate the value?From the information, Jason has a banana. He also has raisin bran cereal, which contains 3.6 grams of fiber and Jason eats 6.9 grams of fiber at breakfast.
Therefore, the equation to find the amount of fiber in the banana will be:
b = 6.9 - 3.6
b = 3.3
Therefore, the amount of fiber in the banana will be 3.3 fibers.

What is the slope of the line that passes through the points (1, -1) and (-8, -7)?
Write your answer in simplest form.
[tex] \boxed{ \sf{ \bold{\purple{m} = \dfrac{2}{3}}}}[/tex]

Explanation:If a line passes through two points, then its slope can be calculated with the following formula:
[tex] \sf{\purple{m} = \dfrac{\blue{y_2}- \green{y_1}}{\red{x_2}- \orange{x_1}}} [/tex]

[tex] \\ [/tex]
Plugging in our values, we get:
[tex] \sf{\purple{m} = \dfrac{\blue{ - 7}- \green{( - 1)}}{\red{ - 8}- \orange{1}}} = \dfrac{ - 7 + 1}{ - 9} = \dfrac{ - 6}{ - 9} [/tex]
[tex] \\ [/tex]
Now, let's simplify our result:
[tex] \sf{ \purple{m} = \dfrac{ - 6}{ - 9} = \dfrac{ \blue{ - 3 \times}2}{ \blue{ - 3 \times }3} = \boxed{ \dfrac{2}{3}}}[/tex]

In this problem, you will investigate the location of the points of concurrency for any equilateral triangle.
b. Verbal Make a conjecture about the relationships among the four points of concurrency of any equilateral triangle.
In an equilateral triangle, all the four points (circumcenter, incenter, orthocenter, and centroid) coincide.
What are the four points of concurrency for a triangle?The incenter is important for angle bisectors; the orthocenter is important for perpendicular bisectors; the circumcenter is important for altitudes; and the centroid is important for medians.
All four points (circumcenter, incenter, orthocenter, and centroid) of an equilateral triangle coincide.
The circumcenter is the point at which the perpendicular bisectors of all three sides of a triangle intersect. The circumcenter of an obtuse-angled triangle is located outside the triangle.
All four points of convergence can be concurrent. Only an equilateral triangle has the same centroid, circumcenter, incenter, and orthocenter at all times.
The 'orthocenter' is the point at which the altitudes of a triangle coincide. The orthocenter of a triangle is the point at which the triangle's three altitudes intersect.

Determine whether AB and XY are

The two lines AB and XY are neither parallel nor perpendicular.
According to the question we have been given the respective coordinates which are :
A = (-3,5) , B = (-1,3)
X = (-4,-8) , Y = (4,-6)
We need to find if AB and XY are parallel , perpendicular or neither.
So to find if they are parallel or perpendicular we will first find out the slope of the line. As when the slope are equal then they are parallel and if they are negative reciprocals of each other then they are perpendicular to each other .
Thus, Slope of AB = [tex]m_{1}[/tex] = [tex]\frac{(y_{2}-y_{1} ) }{(x_{2}-x_{1} ) }[/tex]
[tex]m_{1}[/tex] = (3-5)/(-1+3)

Slope of XY = [tex]m_{2}[/tex] = (-6+8)/(4+4)

Sofia wants to put a flower bed in the corner of her yard by laying a stone border that starts 3 feet from the corner of one fence and ends 6 feet from the corner of the other fence.
We need to find the angles, x and y , the fence make with the border.
Consider the following figure.
First we find the angle x.
Consider the tangent of angle x.
tan(x) = 6/3
tan(x) = 2
x = arctan(2)
x = 63.4°
Now we find the measure of angle CAD that is we find the value of y.
In right triangle ACD,
x + y = 90°

Now, on the left hand side, the 5 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :

Equation of a Straight Line
5.2 Solve 5y-92x-4459 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 5y-92x-4459 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 4459/5 so this line "cuts" the y axis at y=891.80000
y-intercept = 4459/5 = 891.80000
Calculate the X-Intercept :
When y = 0 the value of x is 4459/-92 Our line therefore "cuts" the x axis at x=-48.46739
x-intercept = 4459/-92 = -48.46739
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 891.800 and for x=2.000, the value of y is 928.600. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 928.600 - 891.800 = 36.800 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 36.800/2.000 = 18.400
Geometric figure: Straight Line
Slope = 36.800/2.000 = 18.400
x-intercept = 4459/-92 = -48.46739
y-intercept = 4459/5 = 891.80000

According to the condition we have to take common natural numbers
between above both sets.
So we can see that {1, 2, 3, 4, 5, 6, 7, 8, 9} numbers are common natural numbers.
So, the required solution is {1, 2, 3, 4, 5, 6, 7, 8, 9}.

Find the slope and y -intercept of each line.
y=0
Here, slope is 0 and y-intercept is zero too as line y=0
What is a slope of line?A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane allows one to anticipate whether a line is parallel, perpendicular, or not.
The change in a line's y coordinate relative to its change in x coordinate is referred to as the line's slope. Δy is the net change in the y coordinate, while Δx is the net change in the x coordinate.
Therefore,
m = y₂-y₁/x₂-x₁ (where m denotes the slope) can be used to express how the y coordinate changes in relation to the x coordinate.
Be aware that tan ∅ = y/x
We also refer to this tan as the line's slope
We know that the equation for slope(m) and y - intercept(c) of a line is given by :
y = mx + c
As here y is 0
then, 0 = (0)x + 0
Therefore, slope is 0 and y - intercept is zero too

What are the points of discontinuity of y = x(2 x-1)(x+1) / (x+5)(x+1) ?
The points of discontinuity of the given function can be determined by finding out the common factor in the numerator and denominator, equating and solving it for zero, and finding the corresponding value of f(x).
Point of discontinuity exists when the function does not exist in its domain. Also called holes, it is a value where the function is undefined (zero denominator). The point of discontinuity exists when the numerator and denominator have a common factor(s).
In order to determine the coordinates of point of discontinuity, simplify the function by canceling out the common factor. Hence, canceling out the (x+1)
y = x(2x-1)(x+1)/(x+5)(x+1)=x(2x-1)/(x+5)
Determine the non-permissible value of x by equating the canceled-out factor to zero.
x+1=0
x=-1
Substitute the value of x in the simplified function to find corresponding value of y:
y =x(2x-1)/(x+5) =-1(2(-1)-1)/(-1+5)
=-1(-2-1)/(4)
=-1(-3)/4
=3/4
The point of discontinuity of the function y = x(2x-1)(x+1)/(x+5)(x+1) is (-1,3/4).
