Find the equation of the straight line which cuts off intercepts -5 and 3 on X-axis and Y-axis respectively.
By using the concept of equation of a Straight line,we arrive to the conclusion that the equation of the straight line which cuts off intercepts -5 and 3 on X-axis and Y-axis respectively is 5x - 3y + 15 = 0.
Interception is the point where any line or curve crosses the axis.If the point of crossing line in x-axis then it is known as x-intercept .Similarly, if the point lies on y-axis is is named as y-intercept.
Here,according to the quesion:
x-intercept of the line is,a= -5
y-intercept of the line is,b= 3
The equation of the line here by formed with intercepts is:
[tex]x/a +y/b =1[/tex]
therefore x/(-5) + y/3 =1
- 5x+3y = 15
5x -3y+ 15=0
So,the equation of the mention line is 5x -3y+ 15=0

How to write algebraic equation from statement?
Algebraic equation are the expression which consist the variables, coefficients of variables and constants.
The algebraic equation are used represent the general problem in the mathematical way to solve them.
Steps to write down the simple algebraic equation from statement-
Identify all the factors of the expression.Assume a variable for the changing values.Put a coefficient for the variable, if there is any rate of change of variable.Use constant numbers for the fixed values.Given information-
The given statement is 'sixteen is the same as one and two-tenths times a number added to negative 8'.
The statement given in the problem is talking about a unknown number. Let the unknown number is [tex]n[/tex].
The number is sixteen is the same as one and two-tenths times a number added to negative 8.
This means when our number n, multiplied by the fraction 2/10, and added by the negative 8, then it becomes equal to the number 16. Mathematically,
[tex]16=n+\dfrac{2}{10}\times n+(-8)\\16=1.2n+(-8)[/tex]
Thus the equation can be used to represent the given statement is,

A swimming is filled at a constant rate.when half full the pool had 7500 litres poured into it.a) what fraction has still to be put into the pool?b)How much water will be needed when 5000 litres is already in the pool?
Answer:
A. 1/2 has still to be put in the pool, if we already have 7500 litres in the pool and that's half we need 7500 more which is another half.
B. if 7500 is half the amount that can fit in the pool it means that when the pool is full there are 15000 litres of liquid in the pool meaning that if there is barely 5000 litres we are barely 1/3 of the way done. but if the question is asking if we add 5000 to the 7500 already in the pool we will have 12500 out of the 15000 required to fill the pool, this fraction simplified would be 5/6
What is the equation of the line in slope-intercept form?
Answer:
y=-6x
Step-by-step explanation:
decreasing 6/1 rise/run and no y int
Answer:
y= -6x
Step-by-step explanation:
As you move up vertically from your y-intercept (0,0) six times, you can see that your x-intercept increased by -1. Because your x-intercept has increased by -1, there is a negative sign in front of 6x
There is no number after -6x because the place where your line meets the y-axis (y-intercept) is (0,0).
Which of the following systems of equations has infinitely many solutions?
Answer:
C. y = x + 4, 2y = 2x + 8Step-by-step explanation:
The system has infinitely many solutions if the two equations are equivalent.
We can analyze the given systems to see:
A)
2x + 7x + y = 6 ⇒ 9x + y = 6 ⇒ y = - 9x + 6y = 9x + 6Different slopes, there is one solution
B)
y = 5x + 7y = 2x + 8Different slopes, there is one solution
C)
y = x + 42y = 2x + 8 ⇒ y = x + 4Same lines, infinitely many solutions
D)
7x - y = 10 ⇒ y = 7x - 10y = 6x + 8Different slopes, there is one solution
Solution:
When two equations are equivalent, it is infinitely many solutions because the two lines overlap each other.
Option A - 2x + 7x + y = 6 and y = 9x + 6
=> (9x + y = 6) = (y = 9x + 6)=> (y = -9x + 6) ≠ (y = 9x + 6)Option B - y = 5x + 7 and y = 2x + 8
=> (y = 5x + 7) ≠ (y = 2x + 8)Option C - y = x + 4 and 2y = 2x + 8
=> (y = x + 4) = (2y = 2x + 8)=> (y = x + 4) = (y = 2x/2 + 8/2)=> (y = x + 4) = (y = x + 4)Option D - 7x - y = 10 and y = 6x + 8
=> (7x - y = 10) = (y = 6x + 8)=> (-y = -7x + 10) = (y = 6x + 8)=> (y = 7x - 10) ≠ (y = -6x - 8)Hence, Option C is correct.

Recall the following properties:
[tex]\frac{1}{x^{-a}} = x^a\\\\x^0 = 1[/tex]
Thus, we can rearrange the expression in parts.
[tex](3x)^0 = 1\\\\x^4 = x^4\\\\y^{-4} = \frac{1}{y^4}\\\\\frac{1}{x^{-3}} = x^3\\\\\frac{1}{y^{-7}} = y^7[/tex]
Now, combine these terms:
[tex](1) * x^4 * \frac{1}{y^4} * x^3 * y^7 = \frac{x^4 * x^3 * y^7}{y^4}[/tex]
More properties:
[tex]x^a * x^b = x^{a + b}\\\\\frac{x^a}{x^b} = x^{a - b}[/tex]
Rewrite:
[tex](1) = x^{4 + 3} * y^{7 - 4} = \boxed{\text{D) } x^7y^3}[/tex]
9)
Begin by solving the inside of the parenthesis.
[tex](3^2 + 3^0)^2 = (9 + 1)^2 = 10^2 = 100\\\\(6^{-2} + 3)^0 = 1\\\\100 - 1 = \boxed{ \text{ B. 99}}[/tex]
10)
Simplify the inside of the parenthesis using the above properties.
[tex](\frac{x^2y^5z^3}{xy^7})^{-2} = (\frac{xz^3}{y^2})^{-2}[/tex]
Since there is a negative in the outside exponent, we must take the reciprocal. (flip the numerator and denominator).
[tex]=( \frac{y^2}{xz^3})^2[/tex]
Square both the numerator and denominator.
Recall the property:
[tex](x^a)^b = x^{ab}[/tex]
[tex]= \frac{y^{2*2}}{x^2 * z^{3 * 2}} = \boxed{ \text{C. }\frac{y^4}{x^2z^6}}[/tex]
