Here is a linear equation: y = 1/4x +5/4
Are (1, 1.5) and (12, 4) solutions to the equation?
Yes or No?
PLEASE NEED HELP
Step-by-step explanation:
(1,1.5) is the solution but (12,4) is not the solution of given equation.
1.5=1/4×1+5/4(which is true)
4=1/4×12+5/4(which is false)
The point )1,1.5) is satisfying the equation y=(1/4)x + (5/4) and the point (12,4) is not satisfying.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Given points are (1, 1.5) and (12, 4). To check whether the points are the solution of the equation or not substitute the coordinates in the equation and check if LHS is equal to RHS then it is a solution otherwise not.
Check the point (1,1.5),
y=(1/4)x + (5/4)
4y = x + 5
(1.5)4 = 1 + 5
6 = 6
Check the point (12k,4),
y=(1/4)x + (5/4)
4y = x + 5
(4 x 4 ) = 12 + 5
16 ≠ 17
Therefore, the point )1,1.5) is satisfying the equation y=(1/4)x + (5/4) and the point (12,4) is not satisfying.

What is the distance between two points(2,-6)(-7,1)
Answer:
11.4
Step-by-step explanation:
Find the distance in the x-direction between the x-components: 2 - (-7) = 9.
Similarly: between the y-components: 1 - (-6) = 7
Apply the Pythagorean Theorem: 9^2 + 7^2 = d^2, where d is the desired distance:
81 + 49 = d^2, or d^2 = 130
The distance d is approximately √130 ≈ 11.4
Answer:
Square root of 130
Step-by-step explanation:
Use the distance formula:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}[/tex]
[tex](x_{1}, y_{1} )[/tex] is your first set of coordinates : (2, -6)
[tex](x_{2}, y_{2} )[/tex]is your second set of coordinates : (-7, 1)
Find the number of ways the digits 0,1,2 and 3 can be permuted to give rise to a number greater than 2000
Answer:
12
Step-by-step explanation:
You have to have the 2 or 3 as the first digit.
After that, the other 3 digits can be done in 3! = 6 ways.
So, the total is 2*3! = 12

Jessica baked 3p cookies. Alex baked twice as many cookies as Jessica. Sarah baked 10 fewer cookies than Jessica. Find the total number of cookies baked in terms of p. A. 2p B. 12p – 10 C. 10 – 12p D. 15 p – 10
Answer:
B) 12p - 10
Step-by-step explanation:
J = 3p
A = 2(3p) = 6p
S = 3p - 10
add together:
3p + 6p + 3p - 10 = 12p - 10
A cell phone company charges a flat rate of $2.50 per month, with an additional charge of $0.15 per minute. How many minutes did Laura talk on her cell phone if her monthly bill was $72.25?
Answer:
465 minutes
Step-by-step explanation:
First things first, you have to make an equation! It would be...
2.50+0.15m=72.25
Keep in mind that m stands for minutes.
Now let's solve it!!
First let's subtract 2.50 from both sides.
0.15m=69.75
Now, let's divide 0.15 on both sides!
m= 465
465 minutes!!

find the total surface area of the prism 10 2 6
Answer:
88 units
Step-by-step explanation:
First, we need to find the surface area of each side of the prism. Assuming this is a rectangular prism, judging by the dimensions, that makes things easier.
10*2=20
We'll multiply 20 by 2 since there are 2 sides with these dimensions, resulting in 40 units.
2*6=12
We'll multiply that by 4 since there are 4 sides with these dimensions, resulting in 48 units.
Adding 48 to 40, we get 88.
Hope that helped.

Identify the reference angle ∅ for each given angle, Ф.
When Ф = 300°, ∅=______degrees
When Ф = 225°, ∅=______ degrees
When Ф = 480°, ∅=______degrees
when Ф = -210°, ∅= ______ degrees
Answer:
See below for answers
Step-by-step explanation:
300° is in Quadrant IV, so its reference angle is 360°-300°=60°
225° is in Quadrant III, so its reference angle is 225°-180°=45°
480°=120° is in Quadrant II, so its reference angle is 180°-120°=60°
-210°=150° is in Quadrant II, so its reference angle is 180°-150°=30°

What is function of functions and how are they represented?The function of function, as the name suggests, is functions applied over functions themselves. This is also called function composition.
We have input. We apply one function on that input. Then we apply another function on the output obtained by the first function. This whole function application on the first input is called the function of functions.
The resultant function which maps the input x to the final output is called the function of a function.
If the first function is g and the other function is f, then we can write the resultant function of the function as
(fog)x = f(g(x))
It is Given f(x) = x + 1 and g(x) = x^2, we need to find (g o f) (x)
(g o f)(x) = g(x) + f(x)
= x² + x + 1
