Step-by-step explanation:
Just take two random points, always remember ,take x=0 and find his correspondent y
in this case y=4*0-9=-9
first point (0,-9)
second one:
take any x you want, I took 2 randomly, and y will be
y=4*2-9=8-9=-1
second point is (2,-1)
find these points on graph and connect them with a ruler ! And that is the line you are searching for!
We want to graph the line y = 4*x - 9.
The graph can be seen at the end of the answer.
To graph a given linear function, we need to find two points that belong to the function, and then connect them with a line.
To find the points we just evaluate the function in two different values of x, so let's do that.
For x = 0 we have:
y = 4*0 - 9 = -9
Then we have the point (0, -9)
For x = 1 we have:
y = 4*1 - 9 = 4 - 9 = -5
Then we have the point (1, -5)
Now we just can graph these two points on a coordinate axis, and connect them with a line.
The graph is shown below

y=2x-1
Explanation:
Let’s start! After doing distributive property, the equation will be y-9=2x-10. Now, we move over the “-9” to the other side and add it to -10. So the new equation will be y=2x-1. Can you vote for me on brainliest? Thank you if you do. Have a good day!

Answers
Answer:
x = 73
General Formulas and Concepts:
Order of Operations: BPEMDASStep-by-step explanation:
Step 1: Define equation
(180 - x) + (90 - x) = 124
Step 2: Solve for x
Combine like terms: 270 - 2x = 124Subtract 270 on both sides: -2x = -146Divide -2 on both sides: x = 73Step 3: Check
Plug in x to verify it's a solution.
Substitute: (180 - 73) + (90 - 73) = 124Subtract: 107 + 17 = 124Add: 124 = 12436x-2 + 34x+2 = 180 solve

Reggie plans to have a garden with 36 plants. He wants the ratio of tomato plants to cucumber plants to be 4:5. How many cucumber plants will be in Reggie's garden?
Answers
Answer:
20
Step-by-step explanation:
Total no of plants in a garden = 36
The ratio of tomato plants to cucumber plants to be 4:5.
Let tomato plants are 4x and cucumber plants is 5x.
ATQ,
4x+5x=36
9x = 36
x = 4
For cucumber plant, 5x = 5(4) = 20
So, there are 20 cucumber plants will be in Reggie's garden
(sinA + cosA)/ (secA + cosecA) = sinA* cosA
Answers
Answer:
Proof below
Step-by-step explanation:
Trigonometric Identities
We'll prove that:
[tex]\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=\sin A*\cos A[/tex]
Recall:
[tex]\displaystyle \sec A =\frac{1}{\cos A}[/tex]
[tex]\displaystyle \csc A =\frac{1}{\sin A}[/tex]
Applying those definitions:
[tex]\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=\frac{\sin A+\cos A}{\frac{1}{\cos A}+\frac{1}{\sin A}}[/tex]
Adding the fractions:
[tex]\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=\frac{\sin A+\cos A}{\frac{\sin A+\cos A}{\cos A*\sin A}}[/tex]
Dividing the fractions:
[tex]\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=(\sin A+\cos A)*\frac{\cos A*\sin A}{\sin A+\cos A}[/tex]
Simplifying:
[tex]\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=\cos A*\sin A[/tex]
Hence proved

a) 165
OR
b) 990
Answers
Answer:
1a is 165
1b is 990
Step-by-step explanation:
So the first one is basically asking the possibility of each member being chosen for one of each role.
While the second one is asking the possibility of the person being in one specific role and making that be considered a possibility.
In other words, it's basically easier to get into one of the three roles rather than being in one specific role.
The graph of a function f is shown. Use the graph to estimate the average rate of change from x=-2 to x=0
Answers
Answer:
2
Step-by-step explanation:
Given:
The interval, x = -2 to x = 0.
Required:
Average rate of change from x = -2 to x = 0.
SOLUTION:
From the graph,
If x = -2, f(-2) = 0.
If x = 0, f(0) = 4
Average rate of change = [tex] \frac{f(b) - f(a)}{b - a} [/tex]
Where,
[tex] a = -2, f(a) = 0 [/tex]
[tex] b = 0, f(b) = 4 [/tex]
Plug in the values into the formula:
[tex] = \frac{4 - 0}{0 -(-2)} [/tex]
[tex] = \frac{4}{2} = 2 [/tex]
Average rate of change from x = -2 to x = 0 is 2.

Step-by-step explanation:
The fact that the figures are similar means the side lengths are proportional:
RS/QT = BC/AD
RS/(7 m) = (2.3 m)/(1.4 m)
RS = (7 m)(2.3/1.4) . . . . . . multiply by 7 m
RS = 11.5 m
