Drag numbers to write an equation for the line in slope-intercept form. Numbers may be used once, more than once, or not at all.
Graph of a diagonal line with x-axis and y-axis. A line is passing through co-ordinates (0,5) and (2,-3).
Answer:
y = -4x + 5
Step-by-step explanation:
Here, we want to get the equation of the line that passes through the given points
The general form is;
y = mx + b
where m is the slope and b is the y intercept
To find the slope, we use the slope formula
this is ;
m = (y2-y1)/(x2-x1)
(x1,y1) = (0,5)
(x2,y2) = (2,-3)
m = (-3-5)/(2-0) = -8/2 = -4
To get the y-intercept we simply substitute one of the points
But we know that the y-intercept is the y-value when x = 0
From the point we can see (0,5) which means that the y-intercept is 5
so the equation of the line is;
y = -4x + 5
The equation of the graph in slope intercept form is y = -4x + 5
Using slope intercept equation
y = mx + b
where
m = slope
b = y- intercept
Therefore,
Let's take 2 coordinates to get the slope.
(1, 1)(0, 5)
y-intercept = 5
Therefore,
m = 5 - 1 / 0 - 1 = - 4
y = -4x + 5

Are 2(x + 1) and 2x + 1 equivalent expressions? explain.
I’m not in a hurry, take your time.
Answer:
Yes
Step-by-step explanation:
When you simplify 2(x+1). [MULTIPLY]
It comes 2x+1 so it is equivalent to 2x+1
Yes, 2(x + 1) and 2x + 1 are equivalent algebraic expression.
Given that,
To determine whether the 2(x + 1) and 2x + 1 are equivalent expressions.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Let
y = 2 (x + 1) - - - - - -(1)
z = (2x + 1) - - - - - (2)
from equation1
y = 2 (x + 1)
using the PEMDAS rule, applying operation on the parenthesis 1st as distributive property,
now,
y = 2x + 1
Since the outcome of the equation is equal to equation 2.
Thus, 2(x + 1) and 2x + 1 are equivalent algebraic expression.

which is the graph of f(x) = 3 square root x/4
Answer:
Given function
[tex]f(x)=\dfrac{3}{4}\sqrt{x}[/tex]
Parent function
[tex]f(x)=\sqrt{x}[/tex]
The square root of a negative number cannot be taken, therefore the domain and range of the parent function are restricted:
Domain: [0, ∞)Range: [0, ∞)This means the parent function begins at the origin (0, 0) and is restricted to Quadrant I.
The only transformation the parent function has undergone is it has been multiplied by 3/4, which means it has been stretched vertically by a factor of 3/4. Therefore, the domain and range will not change.
The points shown on the given graphs are all where x = 4.
[tex]\textsf{Graphed function}: \quad f(4)=\dfrac{3}{4}\sqrt{4}=1.5 \implies (4,1.5)[/tex]
Therefore, the graph of the given function is the graph with:

Solve the system of linear equations by substitution. 2x=y−10 x+7=y
Answer:
(-3, 4)
Step-by-step explanation:
2x = y - 10 (y = x +7) so
2x = x +7 - 10
2x = x -3
x = -3
-3 + 7 = y
4 = y
Step-by-step explanation:
2x = y - 10 and x + 7 = y.
By Substitution,
2x = (x + 7) - 10.
=> 2x = x - 3, x = -3.
Therefore y = (-3) + 7 = 4.
The pair of solutions are x = -3, y = 4.

Can someone help me please in thank you
Answer:
Hint: f(x) = y
Step-by-step explanation:
The best way to approach these type of questions is to first substitute the x in the equation with one of the numbers from the table that contains x and y. For example, number 5, f(x) = 8x - 5. One of the numbers states x as 0, meaning I can substitute 0 into the equation as x => f(x) = 8(0) - 5. After that I solve to find f(x), and fill out the slot next to 0. This can be repeated for all blank slots of y. Hope it helped. :)

What is the standard form of 2x2x2x2x2?
Answer:
The standard enthalpy of formation is the energy that would be involved if one mole of the substance were to be formed from its elements that were at standard conditions of temperature and pressure which are 25 degrees C and one atm pressure.
Step-by-step explanation:
The standard form of the given expression 2 × 2 × 2 × 2 × 2 is 2⁵.
The expression is given as follows:
2 × 2 × 2 × 2 × 2
When simplifying repeated multiplication of the same number, we use exponents as a concise representation.
The exponent denotes how many times the base is multiplied by itself. In this case, 2 is multiplied five times (2 × 2 × 2 × 2 × 2).
So, it is equal to 2⁵.
In this form, the base (2) is raised to the power of the number of times it is multiplied (5).
Thus, the standard form of 2 × 2 × 2 × 2 × 2 is 2⁵.

Given m||n, find the value of x.

(7x+3)
(8x+1)°
Answer:
x = 2Step-by-step explanation:
Angles (7x + 3)° and (8x + 1)° are corresponding angles
Therefore:
m║n ⇒ (7x + 3)° = (8x + 1)°
(7x)° + 3° = (8x)° + 1° {subtract (7x)° from both sides}
3° = x° + 1° {subtract 1° from both sides}
2° = x°
x = 2
