How do you convert 20x + 9y = 9 into slope intercept form?
Answer:
[tex] y = - \frac{20}{9} x + 1 [/tex]
Step-by-step explanation:
[tex]20x + 9y = 9 \\ \\ 9y = - 20x + 9 \\ \\ y = - \frac{20}{9} x + \frac{9}{9} \\ \\\purple {y = - \frac{20}{9} x + 1} \\ this \: is \: the \: required \: \\slope \: - intercept \: form \\ \ \\ where \: \\ slope \: = - \frac{20}{9} \\ \\ y - intercept = 1[/tex]

Urgent help pleaseeeeeee
Answer:
2x - 10 = 10 - 3x
Simplifying
2x + -10 = 10 + -3x
Reorder the terms:
-10 + 2x = 10 + -3x
Solving
-10 + 2x = 10 + -3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3x' to each side of the equation.
-10 + 2x + 3x = 10 + -3x + 3x
Combine like terms: 2x + 3x = 5x
-10 + 5x = 10 + -3x + 3x
Combine like terms: -3x + 3x = 0
-10 + 5x = 10 + 0
-10 + 5x = 10
Add '10' to each side of the equation.
-10 + 10 + 5x = 10 + 10
Combine like terms: -10 + 10 = 0
0 + 5x = 10 + 10
5x = 10 + 10
Combine like terms: 10 + 10 = 20
5x = 20
Divide each side by '5'.
x = 4
Simplifying
x = 4

A farmer planted corn in two different fields. He planted 500 seeds of regular corn in Field A and 500 seeds of experimental corn in Field B. At
harvest time, more ears of corn had grown in Field A than in Field B. The farmer concluded that more corn grew in Field A because of the type of corn planted.
Choose two other possible variables that could have caused more corn to grow in Field A.

On a coordinate grid, point A is located in the first quadrant. Point B is located at (2, - 1/2
Point C is a reflection of point B across the y-axis. Which graph shows these three points?
Answer:
the answer I think is B so
The graph attached correctly labels the points A, B and C.
What is the meaning of reflection of figure?A reflection is a mirror image of the shape. An image will reflect through a line, known as the line of reflection.
Given is that on a coordinate grid, point {A} is located in the first quadrant. Point B is located at (2, -1/2). Point C is a reflection of point B across the y-axis.
Since the complete graphs are not given. Refer to the graph attached for correct plotted points.

Which values for x make this inequality false?
Answer:
0, -11, -5, and 20
Step-by-step explanation:
The inequality can be read as x is less than -12.8 (or -12.8 is greater than x)
This means that we need to pick x values that are greater than -12.8 for the inequality to be false.
The values greater than -12.8 are:
0, -11, -5, and 20

A scale model of a boat is 6 inches long. The actual boat is 42 feet long. Which statement(s) are true??
Answer:
B. 1 in = 7 ft
Step-by-step explanation:
Since on the scale the boat was 6 inches and the actual boat was 42 feet, we need to divide to see how many feet correlate to the number on inches on the scale. So we do 42 / 6, which equals 7. This means that for every inch on the scale, it will be 7 feet in real life.

k/7 + 3 − 2k = −3
Explain how to solve the problem. SHOW YOUR WORK!
Answer: 42/13
Step-by-step explanation: Multiply everything by 7 to eliminate the fraction:
k+ 21 - 14k = -21
Isolate the variable:
k - 14k = -21-21
13k= -42
divide the sides by -13.

Which values for x make this inequality false?
Answer:
-3, -0.01, -1/5
Step-by-step explanation:
The inequality can be read as x is greater than 0
-3, -0.01, and -1/5 are all values that are less than 0
So if these are the values of x, then the inequality would be false.

Answer:
See explanation
Step-by-step explanation:
So, the angle for QRS is the interior angle of R. The exterior angle outside of angle R is for the equation you are going to use. Because angle R is on a straight line, the interior angle of R plus the exterior angle of R will equal 180 degrees. From there you should be able to calculate the rest of the angles, I believe you should be able to calculate y first.

Answer:
60
Step-by-step explanation:
So they are showing you a chart in which the column y is determined by the column x, so you divide y/x in any of the rows so that you get the relation.
100/4=25 (which is the same for every row)
It works pretty much the same for the graph, but the relation is different.
Now instead of a chart you have to figure out the values of x and y by looking at the points that make up the line. For example we have a point that is in the coordinate (2, 60), and that represents that the x value is 2 and its correspondent y is 60. And to find the relation we do it as in the first step but now with 2 and 60.
60/2=30 (which is the same for every point)
Finally we just calculate the value of y both in the graph and the chart when x=12
So for the chart: 12*25= 300
And for the graph: 12*30= 360
The difference between those two is 60.

How do you convert 14x + 19y = 20 into slope intercept form?
Subtract 14x from both sides. Then divide both sides by 19
[tex]14x + 19y = 20\\\\19y = 20-14x\\\\19y = -14x+20\\\\y = \frac{-14x+20}{19}\\\\y = \frac{-14x}{19}+\frac{20}{19}\\\\y = -\frac{14}{19}x+\frac{20}{19}\\\\[/tex]
The equation is now in slope intercept form y = mx+b
m = -14/19 is the slope
b = 20/19 is the y intercept
