Answer:
domain is all the values that go into a function, and the range is all the values that come out.
Answer:
Domain: -6 <= x <= 3 and Range -9 <= y <= 5
Step-by-step explanation:
Domain is x
Range is y
(x, y)
The smallest x is -6
The largest x is 3
The smallest y is -9
The largest y is 5
Johny and Rahul divided the benefit of the business in the ratio 7:9. If
Rahul got 4878 rupees as benefit did Johny get?
Answer:
Step-by-step explanation:
7:9 = x:4878
4878/9 times 7
3794 would be your answer
Answer:
3,794 rupees
Step-by-step explanation:
Johny got 7 parts of the benefit while Rahul got 9. This can be represented as a fraction: 7/9
To solve this problem, we can use cross multiplication, where x represents the amount of rupees Johny got:
[tex]\frac{7}{9}[/tex] = [tex]\frac{x}{4878}[/tex]
Multiply 7 by 4,878: 34,146
Multiply 9 by x: 9x
Now the equation looks like this:
9x = 34,146
Divide both sides of the equation by 9 to isolate the x:
9x/9 = 34,146/9
x = 3,794
Johny got 3,794 rupees.

The solution of the equation is x= .
Answer:
[tex]x=1[/tex]
Step-by-step explanation:
Step 1: Cross-Multiply
What cross multiply basically means is that you take both sides of the equation and you multiply my the opposite sides. So you take the top of the left fraction and multiply it by the bottom of the right fraction. You then have an equal sign and then have the bottom of the left fraction multiplied by the top of the right fraction.
[tex]\frac{2}{7}=\frac{6x}{4x+17}[/tex]
[tex]2(4x+17)=7(6x)[/tex]
Step 2: Distribute
[tex]2(4x+17)=7(6x)[/tex]
[tex](2*4x)+(2*17)=(7*6x)[/tex]
[tex]8x+34=42x[/tex]
Step 3: Subtract 8x from both sides
[tex]8x + 34- 8x = 42x - 8x[/tex]
[tex]34=34x[/tex]
Step 4: Divide both sides by 34
[tex]34/34 = 34x/34[/tex]
[tex]1=x[/tex]
Answer: [tex]x=1[/tex]

Which system of linear inequalities is graphed?
I would have put C. Because if you look at the triangle it makes then do the math with squared numbers then you should get c.
what is the solution to this??
4x + 12x =320
then using the solution to this do _x=_
Answer:
x=20
Step-by-step explanation:
Add like terms:
4x + 12x = 16x
16x = 320
320/16 = 20
What is the domain and range please?
Answer:
The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes. (In grammar school, you probably called the domain the replacement set and the range the solution set.
What is the value of x?
Answer:
111
Step-by-step explanation:
You know the angle missing in the triangle is 69 (180-75-36). The angle on a line is 180. So 180-69=111.
OR
Add the two given angles to get 111 as 75+36+(180-x)=180 so if you subract (180-x) it leaves 75+36.

Work out the length x.
Х
7.5 cm
16 cm
Answer:
x = 17.7
Step-by-step explanation:
[tex]a^{2} + b^{2} = c^{2}[/tex]
[tex]7.5^{2} + 16^{2} = x^{2}[/tex]
[tex]56.25 + 256 = x^{2}[/tex]
[tex]312.25 = x^{2}[/tex]
[tex]\sqrt{312.25} = x[/tex]
[tex]17.7 = x[/tex]

3x + y = 13
2x - y = -1
Answer:
3x +y = 13
Or, x=13-y/3......eqn(i)
Now putting the value of x
2x - y = - 1
Or, 2(13-y/3) - y = - 1
Or, 26 - 2y /3 - y = -1
Or, 26 - 2y - 3y = - 3
Or, 26 - 5y = - 3
Or, - 5y = - 3 - 26
Or,y = - 39/ (- 5)
Or, y = 7.8~

Step-by-step explanation:
Mark bought gifts for his friends, and each gift cost $9. Let y represent the total cost and x represent the number of gifts. Write an equation to represent the proportional relationship between the total cost and the number of gifts he bought.
Answer:
y = 9x
Step-by-step explanation:
You can set up linear equations like this: y = mx + b, where m is the slope or rate, and b is the y-intercept.
9 would be the slope, since he has to pay $9 per gift.
The y-intercept is when x = 0, but if he doesn't buy any gifts, he won't have to pay anything, so b = 0. You don't have to include it since it's 0.
So, it's just y = 9x
Hope that helps! :D
Answer:
easy
Step-by-step explanation:
Suppose you are constructing a LEGO Technic Land Rover Defender with a total of 2573 pieces. You have already put together 253 pieces. Every minute you add 5 more pieces. Is the relationship linear? How do you know?
Answer: Yes it is
Step-by-step explanation:
A linear relationship simply put, is a relationship between variables that when constructed, forms a straight line. This happens when y changes at a constant rate if x changes by a constant rate as well for instance, 1.
From this question, assume x is minutes and y is the total number of pieces put together. This means that every time x (minutes) increases by 1, y increases by 5 pieces.
The formula would look like this;
y = 5x + 253
This is a formula for a straight line so indeed, this relationship is linear.

Answer:
a) 3x + y = -5 & b) y = 1/3 ( 21- 9x )
Step-by-step explanation:
a)
3x + y = -5
y = -3x -5
b)
y = 1/3 ( 21 - 9x)
y = -3x + 7
y = 3x + 2.5
the slop is to be same in the parallel lines. slop means m in ( y = mx + c )
so a) & b) are parallel lines. since their m is -3 .
