Graph the line with a slope of 2/5 that goes through (3,1)
Answer:
[tex]y = \dfrac{2x}{5} - \dfrac{1}{5}[/tex]
Step-by-step explanation:
Given:
[tex]\bullet \ \ \text{Slope of line:}\ \dfrac{2}{5} \\\\ \bullet \ \text{Passes through:} \ (3, 1)[/tex]
To determine the equation of the line, we will use point slope form.
Formula of point slope form:
→ y - y₁ = m(x - x₁)Where "x₁" and "y₁" are the coordinates of the point and "m" is the slope.
Substitute the coordinates and the slope:
[tex]:\implies y - 1 = \dfrac{2}{5} (x - 3)[/tex]
Simplify the R.H.S:
[tex]:\implies y - 1 = \dfrac{2x}{5} - \dfrac{6}{5}[/tex]
Add 1 both sides:
[tex]:\implies y - 1 + 1 = \dfrac{2x}{5} - \dfrac{6}{5} + 1[/tex]
Simplify the equation:
[tex]:\implies y = \dfrac{2x}{5} - \dfrac{6}{5} + \dfrac{5}{5}[/tex]
[tex]:\implies \boxed{y = \dfrac{2x}{5} - \dfrac{1}{5}}[/tex]
Graphing the line on a coordinate plane:
In this case, we are already given a point (3, 1). We can simply plot the y-intercept [tex][\bold{\frac{-1}{5} }][/tex] on the coordinate plane. Then, we can draw a straight line through both points. It is suggested that you use a ruler to do so.
Graph attached**
Answer:
See attachment and explanation
Step-by-step explanation:
slope is x/y, which means for each x how many y's it moves by.
so,
2/5 means for every 2 x's it goes up by 5 y's.
so,
you take the point A and go right 2 and go up 5. That's the next point (5,6)
Same with the point other side of A. Go left 2 and go down 5. That's another point (1,-4)
Since, the slope 2/5 is positive, the line will be an increasing line. As shown in the attached image.

Check the picture below, so the hyperbola looks more or less like so, hmmm so is a vertical one, so is opening towards the y-axis, meaning the fraction that is positive is the one with the y-variable, its traverse axis length is 4 units, from +2 to -2, meaning that a = 2, and the distance either focus to the center is √5, so
[tex]\textit{hyperbolas, vertical traverse axis } \\\\ \cfrac{(y- k)^2}{ a^2}-\cfrac{(x- h)^2}{ b^2}=1 \qquad \begin{cases} center\ ( h, k)\\ vertices\ ( h, k\pm a)\\ c=\textit{distance from}\\ \qquad \textit{center to foci}\\ \qquad \sqrt{ a ^2 + b ^2} \end{cases} \\\\[-0.35em] ~\dotfill\\\\ \begin{cases} h=0\\ k=0\\ a=2\\ c=\sqrt{5} \end{cases}\qquad \cfrac{(y- 0)^2}{ 2^2}-\cfrac{(x- 0)^2}{ b^2}=1[/tex]

I need help with 5/9 divided by 3/8
Answer:
40/27 or
1 and 13/27
Step-by-step explanation:
Use Keep-Change-Flip to divide fractions.
Problem:
5/9 ÷ 3/8
KEEP the first fraction, the 5/9, just copy it exactly, no changes.
CHANGE the ÷ to ×
5/9 ×
FLIP the second fraction, the 3/8. Flip it over (reciprocal)
5/9 × 8/3
Now do this problem. You can "cancel" (which is really dividing) or multiply straight across (top×top, bottom×bottom)
5/9 × 8/3
= 40/27
This cannot be reduced. It is a perfectly good answer just like this. But since there is a larger number on top, your teacher/class/book/program, might want you to change it to a mixed number.
40/27 = 1 13/27
Congruent to angle B
Answer:
-------------------
Step-by-step explanation:
while the other answer is not wrong in this case, it is not complete.
"congruent angle" means the angles are equal.
so, yes, diagonally down is one, but also at exactly the same 2 spots over at the intersection point of the blue line with the second parallel red line.

Sofia buys a two-gallon bottle of juice for $35.84. what is the unit rate of the cost of the juice per fluid ounce?
how many fluid ounces of juice did sofia buy?
Answer:
$0.14 per fl oz /// 256 fl oz of juice.
Step-by-step explanation:
The number of fluid oz per gallon = 128
2 gallons = 256 fl oz
$35.84/256= $0.14.
--------------------------------------
1 gallon = 128 fl oz.
128x2 = 256
2 gallons = 256 fl oz.
Jamie has 70 coins. They total $6.30. If they are only dimes and nickels find out how many of each she has.
Answer:
Jamie has 14 nickels and 56 dimes
Step-by-step explanation:
Start by identifying labels for the # of dimes and nickles. Lets use x for nickels and y for dimes.
From here you can make two formulas (x + y = 70) and (5x + 10y = 630) when you put them into a graphing calculator they should intersect at (14,56) which means the x = 14 and y = 56

Let Tn, be the number of dots in figure.
How many dots are there in figure 30?
Look at the picture (don't mind of the highlighted ones).
Answer:
4294967293 dots
Step-by-step explanation:
Figure 1 has 5 dots.
Figure 2 has 13 dots.
Figure 3 has 29 dots.
Subtract and find different of each term:
13-5 = 829-13 = 16Let [tex]\displaystyle \large{b_n}[/tex] be sequence of difference (and the sequence appears to be geometric.)
So for [tex]\displaystyle \large{b_n}[/tex], find the common ratio which is 2.
Hence, [tex]\displaystyle \large{b_n = 8(2)^{n-1}}[/tex] - recall geometric sequence formula below:
[tex]\displaystyle \large{a_n = a_1r^{n-1}}[/tex]
The sequence of difference [tex]\displaystyle \large{b_n=8(2)^{n-1}}[/tex] can be simplified to:
[tex]\displaystyle \large{b_n=2^3(2)^{n-1}}\\\displaystyle \large{b_n=2^{n+2}}[/tex]
Now to find the original sequence:
[tex]\displaystyle \large{a_n = a_1 + \sum_{k=1}^{n-1}b_k}[/tex]
Hence:
[tex]\displaystyle \large{T_n=5+\sum_{k=1}^{n-1}8(2)^{k-1}}[/tex]
Recall:
[tex]\displaystyle \large{\sum_{k=1}^{n-1} a_1r^{n-1} =a_1\left( \dfrac{1-r^{n-1}}{1-r}\right)}[/tex]
Therefore:
[tex]\displaystyle \large{T_n=5+\sum_{k=1}^{n-1}8(2)^{k-1}}\\\displaystyle \large{T_n=5+8\left(\dfrac{1-2^{n-1}}{1-2}\right)}\\\displaystyle \large{T_n=5+8\left(\dfrac{1-2^{n-1}}{-1}\right)}\\\\\displaystyle \large{T_n=5+8(-1+2^{n-1})}\\\displaystyle \large{T_n=5-8+8(2)^{n-1}}\\\displaystyle \large{T_n=2^{n+2}-3}[/tex]
Therefore, the sequence for 5,13,29 is [tex]\displaystyle \large{2^{n+2}-3}[/tex].
Therefore, in figure 30:
[tex]\displaystyle \large{T_{30}=2^{30+2}-3}\\\displaystyle \large{T_{30}=2^{32}-3}\\\displaystyle \large{T_{30}=4294967293}[/tex]
Therefore, there are 4294967293 dots in figure 30
A straw forms a cylinder with a length of 270 millimeters and a diameter of 6 millimeters. What is the volume of the straw in cubic millimeters? Round your answer to the nearest hundredth.
The volume of the cylindrical straw of diameter 6 mm and length of 270 mm is 7630.20 mm³
Volume of a cylinder
volume of a cylinder = πr²h
Therefore,
r = radius of the baseh = height of the cylinderHence,
radius = r = 6 / 2 = 3 mm
