What are the vertex and x-intercepts of the graph of y= (x+4) (x-2)
Answers
Answer:
Step-by-step explanation:
the x-intercepts of the graph is (-4, 0) and (2, 0)
y = x^2 + 2x - 8
(2/2) = 1
y = (1)^2 + 2(1) - 8 = 1 + 2 - 8 = 3 - 8 = -5
(1, -5) is the vertex

Answer:
x= 2, y= 1
Step-by-step explanation:
First label the 2 equations:
3x +7y= 13 -----(1)
5x +2y= 12 -----(2)
Make x or y the subject of formula for one of the equation so that we can substitute its value into the 2nd equation.
Here, I am making y the subject of formula in the 2nd equation.
5x +2y= 12
2y= 12 -5x

The addition is one of the four fundamental mathematical operations. The three consecutive terms are 24, 25, 26.
What is Addition?
The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.
Let the first integer be represented by x. Then the other two integers will be (x+1) and (x+2).
Since it is given that the sum of twice the smallest and 3 times the largest is 126. Therefore we can write,
2x + 3(x+2) = 126
2x + 3x + 6 = 126
5x = 126 - 6
5x = 120
x = 120/5
x = 24
Thus, the three consecutive terms are,
x = 24
x + 1 = 25
x + 2 = 26
Hence, the three consecutive terms are 24, 25, and 26.

Answer: 8/10
Step-by-step explanation: Using the place value chart, we can see that 0.8 means eight-tenths which can be written as the fraction 8/10. Since 8/10 is not in lowest terms, we need to divide both the numerator and denominator by the greatest common factor of 8 and 10 which is 2 to get 4/5.
Therefore, 0.8 can be written as the fraction 8/10.
The decimal number 0.8 in the simplest fraction form will be 4/5.
A fraction number is a number that represents the part of the whole, where the whole can be any number. It is in the form of a numerator and a denominator.
The decimal number is given below:
⇒ 0.8
Multiply and divide the expression by 10. Then we have
⇒ 0.8 x 10 / 10
⇒ 8 / 10
⇒ 4 / 5

x = –9
x = –3
x = 0
x = 6
Answers
(x – 3)(x + 9) = –27
x^2 + 9x - 3x - 27 = -27
x^2 + 6x - 27 + 27 = 0
x^2 + 6x = 0
x * (x + 6) = 0
1. x = 0
2. x = -6
The correct result would be x = 0.
By evaluating the quadraticexpression at each realnumber, we conclude that x = 0 is a solution (root) to (x - 3) · (x + 9) = -27. (Correct choice: C)
How to find the roots of a given polynomic expression
In this question we must find a solution for a polynomicexpression. There are several approaches to find them. Since we have a polynomicexpression as a product of binomials, we can determine the solution by evaluating at each choice:
x = 0
(0 - 3) · (0 + 9) = -27
(-3) · 9 = -27
-27 = -27
By evaluating the quadraticexpression at each realnumber, we conclude that x = 0 is a solution (root) to (x - 3) · (x + 9) = -27. (Correct choice: C)
