Graph the lines in standard form 2x+y=9
Answers
Answer:
to graph this all you need to do is plot the y-intercerpt which is 9 in this case. then use the slop (-2) which means go two down from the y intercept and one to the right. all you need to do then is connect the points with a line.

Answer:
see attached
Step-by-step explanation:
A graphing calculator produces a graph very nicely.
__
Setting x=0, you have the equation y=9, so you know the y-intercept.
Setting y=0, you have the equation 2x=9, so you know the x-intercept is 9/2 = 4.5. It can be easier to set y=1 to find the corresponding point x=(9-1)/2 = 4.
Through the points (0, 9) and (4, 1), you can draw the line representing the relation.

Write the slope-intercept form of the equation of each line. Identify the slopes y-intercept
Answers
Answer:
10) m: 6
b: 5
y= 6x +5
12) m: -2
b: -1
y= -2x-1
14) m: 1
b: 0
y= x
Step-by-step explanation:
The slope-intercept form is the form y=mx+b
m is the slope. You can find it by finding two points that the line intersects, and counting the number of units between them.
Remember the slope is "rise over run", so, the difference in y over the difference in x.
b is the y-intercept. You can find it by looking at where the line crosses the y-axis.
Hope this helps you out!

Find x. Round to the nearest tenth if needed.
Answers
Answer:
x = 16
Step-by-step explanation:
Use that the addition of all internal angles of a triangle must add up to 180, and the fact that the two given triangles are similar:
51 + 65 + 4 x = 180
combine and solve for "x"
116 + 4 x = 180
4 x = 180 - 116
4 x = 64
x = 64 / 4
x = 16
Answer:
x = 16
Step-by-step explanation:
A triangle is 180 degrees. Since two of the angles are congruent to each other, the third angle must be congruent as well. This means that the third measure for both triangles is 4x. Knowing all of this, we can solve for x:
65 + 51 + 4x = 180
116 + 4x = 180
4x = 64
x = 16
Solve for x
0.5(5−7x)=8−(4x+6)
x = ???
Answers
0.5 (5 - 7x) = 8 - (4x+6)
2.5 - 3.5x = 8 - 4x + 6
2.5 - 3.5x = 2 - 4x
-3.5x + 4x = 2 - 2.5
0.5x = -0.5
X = -1
Your answer is x = -1. I hope this helps!

Answers
Answer:
4. y = -1/2x + 5
5. y = -1/3x + 3
6. y = 1
Step-by-step explanation:
For #4:
Because these lines are parallel, we know that they will have the same slope.
To get b, or the y-intercept, I just started at the point (4,4) and used the slope to work backwards to the y-axis. This is really not the best way to do it (especially with big numbers) but it works in a pinch. Also, I forgot the better way :/
For #5:
These lines are perpendicular. That means that the slopes are reciprocals of the other and, when multiplied with each other, the answer will be -1.
The reciprocal of 3 is -1/3.
To get the y-intercept, I did the same as above.
For #6:
x = 2 is a vertical line. To make a line perpendicular to it, that is, to make a line that intersects with it at 90°, the answer line will have to be horizontal.
That means that our answer is y = ?
We know that the line passes through a very specific point (2,1), and the line provided in the question already gives us the x value of this point. All we have to do is set y equal to the y value.
So, y = 1.
I hope this helps!

help me (a) The total cost of rent is determined by recording x months of rent at $1400 per month, plus a $150 application fee.
Answers
Answer:
$1400x + $150
Step-by-step explanation:
Let the total cost of rent used for a month be $1400 plus a $150 application fee.
This means that;
Total cost (1 month) = $1400(1) + $150 = $1550
TO calculate the cost for x months, we will simply multiply x with the cost of rent for 1 month as shown.
The cost of rent for x month = 1400x * $150
The cost of rent for x month = $1400x + $150 (application fee are paid only once)

Bill makes $30.00 per day. He makes twice as much as hack makes before jacks salary was doubled. How much does jack make now?
Answers
Answer:
$30.00
Step-by-step explanation:
Jack's original salary before it was doubled was $15.00 per day.
Let's assume Jack's original salary is "x" dollars per day.
According to the given information, Bill makes $30.00 per day, which is twice as much as Jack made before his salary was doubled. So, before Jack's salary was doubled, he made "x" dollars per day.
After Jack's salary was doubled, he makes 2 * x = 2x dollars per day.
Now, we know that Bill makes $30.00 per day, which is equivalent to the new salary of Jack after it was doubled.
So, we can set up an equation:
2x = $30.00
To find the value of "x," we can divide both sides by 2:
x = $30.00 / 2
x = $15.00
Therefore, Jack's original salary before it was doubled was $15.00 per day.
