What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
Let the number is x,
According to given condition,
3×x²= 2×x+6
⇒3x²= 2x+6
⇒3x²-2x-6=0
There are two values of x, -1.12 and 1.786
Neglect negative value,
By solving the equation, the value of x is 1.786.

A researcher wishes to estimate the proportion of adults who have high-speed Internet access. What size sample should be obtained if she wishes the estimate to be within 0.03 with 90% confidence if (a) she uses a previous estimate of 0.34?(b) she does not use any prior estimates? n=_____(Round up to the nearest integer.)
Answer:
675 samples
752 samples
Step-by-step explanation:
Given that :
α = 90%
E = 0.03
Previous estimate (p) = 0.34
Estimated sample proportion (n)
n = p *q * (Zcritical /E)
Zcritical = α/2 = (1 - 0.9) /2 = 0.1 / 2 = 0.05
Z0.05 = 1.645 ( Z probability calculator)
q = 1 - p = 1 - 0.34 = 0.66
n = 0.34 * 0.66 * (1.645/0.03)^2
n = 674.70
n = 675
B.) without prior estimate given ;
p and q should have equal probability
Hence ;
p = 0.5 ; q = 0.5
n = 0.5 * 0.5 * (1.645/0.03)^2
n = 751.67361
n = 752

Answer:
x = 1.4
Step-by-step explanation:
6 - 2x = 8(x -1)
6 - 2x = 8x - 8
collecting like terms
-2x - 8x = -8 - 6
-10x = -14
10x = 14
dividing both sides by 10
x = 14/10
x = 1.40 (2d.p)

The required domain of the function given is all real numbers. Option B is correct.
Given that,
To determine the domain of the given function shown in the graph.
The domain is defined as the values of the independent variable for which there is a certain value of the dependent variable exists in the range of the function.
Here,
As shown in the graph function is given as y = 1.5,
So the domain x for the given function is given as all real values of the x from -∞ to +∞.
Thus, the required domain of the function given is all real numbers. Option B is correct.

Let g(x) = -2(3x + 4)(x - 1)(x – 3)2 be a polynomial function.
1. Sketch a graph of the polynomial.
2. Name all horizontal and
vertical intercepts of the graph.
3. State the end behavior of g.
Answer:
Hope this helped a little :)
Step-by-step explanation:
The all horizontal and vertical intercepts of the graph are x-intercept(s): (-4/3, 0), (1,0), (3,0) and y-intercept(s): (0,72).
The given function is g(x) = -2(3x+4)(x-1)(x-3)².
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
1) The sketch a graph of the polynomial is given below.
2) To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.
x-intercept(s):
(-4/3, 0), (1,0), (3,0)
y-intercept(s): (0,72)
3) Use the degree and the leading coefficient to determine the behavior.
Falls to the left and falls to the right
Therefore, the all horizontal and vertical intercepts of the graph are x-intercept(s): (-4/3, 0), (1,0), (3,0) and y-intercept(s): (0,72).

USING ALGEBRA TILES Write the sum of the two algebraic expressions modeled by the algebra tiles. Let x be the variable. Then use the algebra tiles to simplify the expression. math
Answer:
the picture is super blurry can u change the picture and I'll do my best to answer it :)
Step-by-step explanation:
The sum of the two algebraic expressions modeled by the algebra tiles is 3x - 1.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
We have to determine the sum of the two algebraic expressions modeled by the algebra tiles.
Let the variable would be x.
List the algebraic expression by the algebra modeling tiles
⇒ (2x - 6) + (x +5)
⇒ 2x - 6 + x +5
Rearrange the terms and apply the arithmetic operation
⇒ 3x - 1
