“Draw the graph of the line with equation y=3/4x-2”

Mathematics
1 answer:
Ugo [173]2 years ago
3 0

Step-by-step explanation:

You have multiple ways, all revolving around finding 2 points.

The easiest point to use is the y intercept (the value of y when x=0), and is the constant term, giving you (0; -2)

The second point can be found in a number of ways:

  • Look for the x intercept (when y=0), and you will get some point by solving for x;
  • put any value of x you haven't used so far (ie, 0), compute it, and you will find a second point.
  • plug a "smarter" value of x that will make computation easy: in this case you have a fraction, so I would pick the denominator to simplify: (you got \frac34, so x=4 \rightarrow y=\frac34(4)-2 = 3-2=1 giving a second point (4;1))
  • since the equation is in <em>slope-intercept </em>form, Just remember the slope tells you how many vertical units you move (numerator) when you move right the number of units in the denominator, with the sign telling you up or down: in our case you move 3 up (since it's positive) every 4 "steps" right.

In any case, the graph will look something like the one in the image

Convert decimal to fraction
scoray [572]
Converting decimals into fractions is simple, all you have to do is think about the number, for example .25, if you look at it you realize it's 1/4 of 1, so it's naturally 1/4, you do this with all of them

A bead is formed by drilling a cylindrical hole of 2mm diameter through a sphere with an 8mm diameter. Estimate the volume of th
nydimaria [60]
The bead is in a cylindrical shape and the formula for solving the volume of a cylinder is V=pi*r²*h where "r" is the radius, "h" for the height.
We have given values such as:
r=diameter/2 = 2/2 = 1mm
h= 8mm
Solving for the volume, we have:
V=3.14*1²*8
V=24.12 mm²

Why did Martin Luther write the 95 theses?
Georgia [21]
The 95 thesis was written to speak out against the wrongdoing of the church and the pope. All of the other answers don’t necessarily make sense, because he did not write it to be famous, to be the pope, etc.

Vadim26 [7]

Answer:

3.11

Step-by-step explanation:

f(4)=f(4-1)+2

=f(3)+2

=f(3-1)+2+2

=f(2)+4

=f(2-1)+2+4

=f(1)+6

=5+6 (f(1)=5)

=11
