Seven more than twice a number is 23.
Answers
Answer:
x=8
Step-by-step explanation:
In other words, you are looking for a number (x) that if you multiply it by two (same as twice) and then add 7, you get 23.
To solve this, you first write the problem as an algebra equation as follows: 2x + 7 = 23
Then you solve the equation by subtracting 7 from both sides, and then divide both sides by 2. Here is the math to illustrate better:
2x + 7 = 23
2x + 7 - 7 = 23 - 7
2x = 16
2x/2 = 16/2
x = 8
Answer:
i think it is 16
Step-by-step explanation:
16 + 7 = 23

Considering it's y-intercept and vertex, the equation of the parabola is given by:
What is the equation of a parabola given it’s vertex?
The equation of a quadratic function, of vertex (h,k), is given by:
In which a is the leading coefficient.
In this problem, the vertex is (1,0), hence h = 1, k = 0 and:
The y-intercept is of 1, hence, when x = 0, y = 1, so:
Hence, the equation is:

Answer:
A
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (1, 0) , thus
y = a(x - 1)² + 0
To find a substitute the coordinates of the y- intercept (0, 1) into the equation
1 = a(- 1)² = a , thus
a = 1
y = (x - 1)² → A

2(x - 2)² = 8(7 + y)
Rewrite the expression as follows:
7 + y = (2/8)*(x-2)² = (1/4)*(x-2)²
y = (1/4)(x-2)² - 7
To find the inverse, switch x and y, and solve for y.
x = (1/4)(y-2)² - 7
Multiply through by 4.
4x = (y-2)² - 28
(y-2)² = 4x + 28
y - 2 = √(4x + 28)
y = 2 +/- √(4x + 28)
This expression is the inverse of the given expression.
Therefore the answer is D."
