Answer:
12.8
Step-by-step explanation:
The equation 5 x minus 10 y = 30 is written in standard form. What is the first step when solving for x?
Add 5x to both sides of the equation.
Subtract 5x from both sides of the equation.
Add 10y to both sides of the equation.
Subtract 10y from both sides of the equation.
Answer:
Add 10y to both sides.
Step-by-step explanation:
Answer:
C) Add 10y to both sides of the equation
Step-by-step explanation:
We need to get x by itself.
So to make the 10y go to the other side, we add 10y to cancel it on the left, but move it to the right.
The equation now looks like this:
5x = 30 + 10y

Find the y - intercept of the line:
8
y=-3 -
7
Select one:
O a. 5/3
O b. - 5/3
O c.8/7.
O d. - 877
Answer:
d. [tex] -\frac{8}{7} [/tex]
Step-by-step explanation:
The y-intercept value in a given equation in the slope-intercept form, y = mx + b sis represented by b.
Thus, given the line [tex] y = \frac{-5x}{3} - \frac{8}{7} [/tex], the value of b (y-intercept) is represented as [tex] -\frac{8}{7} [/tex].
It is the value of y when x = 0.
Therefore, the y-intercept of the line is [tex] -\frac{8}{7} [/tex].

A glacier travels 10 kilometers in 20 years, what is its speed?
Answer:
To change from meters per day into kilometers per year, you just have to change from meters to kilometers and from days to years. You just multiply/divide by the unit conversions (for example, 1000 meters per kilometer) in a way that cancels out the units and leaves just kilometers and years:
Step-by-step explanation:

You are a landscaper, and you are designing a fence to enclose part of a yard. The section to be enclosed is rectangular and has a width of 21 feet and a length of 38 feet. What length of fence, in feet, will you need to enclose this part of the yard? 59 60 118 120 798
Answer:
If you draw this out, you can see that total fence equation will be:
2L + 4W = 1200
Simplify, divide by 2
L + 2W = 600
L = (600-2W)
:
Area;
A = L*W
Substitute (600-2W) for L:
A = (600-2W)*W
A = -2W^2 + 600W; a quadratic equation
:
The dimension that will produce the greatest area will be the "axis of symmetry
which is: x = %28-b%29%2F%282a%29
:
In this equation a=-2, b=600
W = %28-600%29%2F%282%2A-2%29
W = %28-600%29%2F%28-4%29
W = +150 ft is the width
:
Find the length
L = 600 - 2(150)
L = 300 ft is the length
:
We can say the a field 300 by 150 gives he greatest area
:
This illustrated on a graph where y axis is the area and x axis is the width:
