Which technique is most appropriate to solve this equation?
x2 + 6= 31
Question 2 options:
quadratic formula
zero product property
square root property
Answer:
Square root property
Step-by-step explanation:
The given equation is :
[tex]x^2+6=31[/tex]
We need to write the most appropriated technique to solve the above equation.
Subtracting both sides of the above equation by 6 such that,
[tex]x^2+6-6=31-6\\\\x^2=25[/tex]
Now taking square root on both sides we get :
[tex]x=\sqrt{25}[/tex]
The square root property is used here, such that the value of x is :
[tex]x=\pm 5[/tex]

D) 10xy − 2z: associative property
Answer:
5(x + y) − 2z; Distributive Property
Step-by-step explanation:
The coefficient for both 5x and 5y is 5; therefore, use the distributive property to rewrite the sum as 5(x + y).

Answer:
y = 2/3x +4
Step-by-step explanation:
The y intercept is where the line crosses the y axis
y intercept =4
We can find the slope using two points on the line
(0,4) and (3,6)
m = (y2-y1)/(x2-x1)
= (6-4)/(3-0)
= 2/3
The equation of a line in slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = 2/3x +4
Answer:
y = 2/3x +4
Step-by-step explanation:
let the 2 unknown be a and b
X = 0, Y = 4 -> 4 = 0*a+b -> b = 4
Y =0, X = -6 -> 0 = -6*a + 4 -> a = -4/-6 = 2/3
-> y = 2/3x +4
Part A: Which function(s) could have at most 1 x-intercept? Select all that apply.
Linear
Select a Value
Linear
Quadratic, f(x) = x2 – 5x - 2
Exponential, Linear, y = 2x + 4, f(x) = 3.47
y = 2x + 4, Exponential
f(x) = x2 – 5x – 2, Linear
f(x) = 3.4"
Answer:
y = 2x + 4Step-by-step explanation:
The linear functions are the ones that can have at most 1 x-intercept. Specifically, slant lines and vertical lines have this characteristic.
The quadratic function doesn't have this characteristic because there are cases where it intercepts x-axis at two points (concave down).
Additionally, the exponential function doesn't have any x-intercept, because its range is restricted.
Therefore, the right asnwer is the linear function
The function that could have at most 1 x-intercept is y = 2x + 4.
What is a linear function?It is the function that can have at most 1 x-intercept. When slant lines and vertical lines should contain the attributes.
The quadratic function doesn't have this attribute since there are cases where it intercepts the x-axis at two points that represent concave down.
Moreover, the exponential function doesn't have an x-intercept, since its range is restricted.
Therefore, it should be a linear function.

The product of the given numbers is 1.61 × 10⁸.
What is meant by Scientific Notation?Scientific notation is a way of writing a large number or small number with many digits in a simpler form using the power of 10.
For example, 30,000 can be written as 3 × 10⁴.
Given that,
We have to multiply the numbers (2.3 x 10¹) (7 x 10⁶).
The numbers in scientific notation uses exponents.
So we have to use the product rule of exponents here.
(2.3 x 10¹) (7 x 10⁶) = (2.3 × 7) × (10¹ x 10⁶)
= 16.1 × (10¹ x 10⁶)
We have the product rule, xᵃ . xᵇ = xᵃ⁺ᵇ
So the product is,
(2.3 x 10¹) (7 x 10⁶) = 16.1 × (10¹⁺⁶)
= 16.1 × 10⁷
= 1.61 × 10⁸
Hence the product in scientific notation is 1.61 × 10⁸.
