Rewrite the equation 2y - 4x = 10 in function notation where f(x)= y.
f(x)=
Answer:
Answer:
f(x) = 5 + 2x
y+4x^2-1 is the same as y=-4x^2+1, then replace y with f(x); f(x)=-4x^2+1. After you do that, replace x with 2; f(2)=-4(2)^2+1. 2^2=4, 4 times -4=-16, -16+1=-15. So f(2)=-15.
Answer:
f(x) = 5 + 2x
Step-by-step explanation:
2y - 4x = 10
+4x +4x
2y = 10 + 4x
Now we have a new equation but we have to isolate the variable y.
[tex]\frac{2y}{2}[/tex] = [tex]\frac{10 + 4x}{2}[/tex] Then divide to solve for y.
y = 5 + 2x
Since f(x) is the same thing/equal to y we can just replace that.
f(x) = 5 + 2x
Hope that helps and have a great day!

Which expression is equivalent to sin(1.8x) sin(0.5x)
Answer: 0.5(cos 1.3x − cos 2.3 x)
Step-by-step explanation:
Hey there!
In trigonometry which relates the sides and angles of the triangle, there is an identity which states that,
(sinA) (sinB) = 0.5(cos (A − B) − cos (A + B) )
In this item, our A and B are 1.8x and 0.5x, respectively.
Substituting,
sin(1.8x)sin(0.5x) = 0.5(cos (1.8x − 0.5x) - cos(1.8x + 0.5x))
sin(1.8x)sin(0.5x) = 0.5(cos 1.3x − cos 2.3 x)

- WHATS THE NEGATIVE SLOPE??
- FIND M’S SLOPE
PLEASEEESWEEEEEEEEEEE⚠️
Answer:
Question 1: The negative slope is line j.
Question 2: M's Slope is 1/2.
Step-by-step explanation:
Question 1:
Way 1:
The negative slope is line j because it moves from left to right where the y points decrease while x is increasing.
Way 2:
Finding the slope also finds if it has a negative or a positive slope.
Line j has points (-1,3) and (0,0).
To solve for slope, you have to do (y2-y1)/(x2-x1).
To substitute the values, it gets to (0-3)/(0-(-1)).
To simplify that, it gets to -3/(0+1) which equals to -3/1. -3/1 in other words is -3.
Since the slope is a negative number, it has a negative slope.
Question 2:
To find the slope of line m, you have to find two points first.
The two points there are is (4,2) and (0,0).
Then you have to use the equation (y2-y1)/(x2-x1).
Once you find the numbers, you plug it into the equation getting (0-2)/(0-4).
To simplify that it gets to -2/-4. That equals -1/-2 once simplifying the fraction.
Since there are negatives in both numerator and denominator, the negative sign gets removed and it becomes 1/2.
Therefore, the slope for line M is 1/2.
You start at (-2, 4). You move up 1 unit and down 5 units. Where do you end?
Answer: (-2,0)

The direct variation has the same value or expression as that of the slope of a straight line given by - m = y/x.
What is the general equation of a straight line?
The general equation of a straight line is -
y = mx + c
where m is slope of line
c is the y - intercept
Given is the direct variation of a quantity.
The direct variation of a quantity in the equation of a straight line is represented by the slope of a straight line. Mathematically, we can write -
y = mx + c
for y - intercept = [c] = 0, we can write -
y = mx
m = y/x
which is the representation of direct variation.
Therefore, the direct variation has the same value or expression as that of the slope of a straight line given by - m = y/x.

in and her brother each created a scale drawing of the backyard, but at different scales. Lin used a scale of 1 inch to 1 foot. Her brother used a scale of 1 inch to 1 yard. Express the scales for the drawings without units.
Whose drawing is larger?
Answer:
Lin's drawing is larger.
Step-by-step explanation:
Say that their backyard is 1 yard, her brother's scale drawing would only be 1 inch, but Lin's scale drawing would be 3 inches. From this you can take away that the smaller the scale the bigger the scale drawing, (does that sentence make any sense?)
