Answer:
y = - 3x + 4
Step-by-step explanation:
Line is passing through the points (1, 1) & (0, 4)
Slope of line = (4-1)/(0-1) = 3/(-1) = - 3
Equation of line
y = mx + b
Here m = - 3, b = 4
y = - 3x + 4
Using point (1, 1)
y - 1= - 3(x - 1)
y = - 3x +3 +1
y = - 3x + 4

Karen performed a transformation of (C) counterclockwise rotation of 90 degrees about origin
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
If a point A(x, y) is rotated 90° counterclockwise about the origin, the new point is at A'(-y, x).
Parallelogram ABCD has vertices at A(-4,-1) , B (-7,-6) , C (-14, -6) , D(-11, -1), if it is rotated 90° counterclockwise about the origin, the new point would be at A'(1.-4) , B'(6.-7), C'(6.-14) , D'(1.-11)

Answer:.
m= 116 degrees
a=41 degrees
Step-by-step explanation:
Explaination: add 89+50+64 = 203
the line that m is on should equal 180. so subtract 64 from 180 and you get 116 degrees. then add 89+50+64+116=319
360-319= 41

Select the correct answer. Which function has a domain of all real numbers? A.y=(x+2)^ 1/4 B.y=-x^ 1/2+5 C.y=-2(3x)^1/6 D.y=(2x)^1/3-7
Answers
The option D shows a function has a domain of all real numbers.
Which is the Domain of a Function?
The domain of a function is the set of input values for which the function is real and defined. In the other words, when you define the domain, you are indicating for which values x the function is real and defined.
Letter A - [tex]y=\left(x+2\right)^{^{\frac{1}{4}}\:}[/tex], as you have an even exponent, the results for y should be greater or equal than zero. Thus,[tex]\left(x+2\right)^{^{\frac{1}{4}}\:}=\sqrt[4]{x+2}[/tex]
Therefore, the function domain is x [tex]\geq[/tex]-2.
Letter B - [tex]y=-x^{\frac{1}{2}}^{\:}+5[/tex], as you have an even exponent, the results for y should be greater or equal than zero. Thus,[tex]-x^{\frac{1}{2}}^{\:}+5=-\sqrt{x} +5[/tex]
x [tex]\geq[/tex] 0
Therefore, the function domain is x [tex]\geq[/tex] 0.
Letter C - [tex]y=-2\left(3x\right)^{\frac{1}{6}}[/tex], as you have an even exponent, the results for y should be greater or equal than zero. Thus,[tex]-2\left(3x\right)^{\frac{1}{6}}=-2*\sqrt[6]{3x}[/tex]
3x [tex]\geq[/tex] 0
x [tex]\geq[/tex] 0
Therefore, the function domain is x [tex]\geq[/tex] 0.
Letter D - [tex]y=\left(2x\right)^{\frac{1}{3}}-7[/tex], as you have an odd exponent, the results for y has no undefined points nor domain constraints. Thus,[tex]\left(2x\right)^{\frac{1}{3}}-7=y=\sqrt[3]{2x} -7\\ \\[/tex]
Therefore, the function domain is [tex]-\infty \: < x < \infty \:[/tex].

What is a inequality?In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions.
On one day, x, the outside temperature never fell below 1°. A automobile was always at least 4 degrees warmer inside than it was outdoors.
y -1 is the inequality for the first line.
Y > x + 4 is the inequality that represents the second line.
The darkened area is therefore above the first line, which is a solid horizontal line.
The shaded area lies above and to the left of the second line, which has a broken line and a positive slope.
Therefore, the correct option is A.

Answers
The empire state building is taller than a chair seat by three orders of magnitude.
What are orders of magnitude?Orders of magnitude refer to the classification based on the sizes of two objects against each other.
Orders of magnitude range in the power of 10 or 10ⁿ.
Data and Calculations:Orders of Magnitude:
10x = 1 order of magnitude
100x = 2nd order of magnitude
1000x = 3rd order of magnitude
Empire State Building = 1,500 feet
Chair seat = 1.5 feet
Order of magnitude = 1,000x (1,500/1.5)
Thus, the Empire State Building is about a thousand times taller than a chair seat or three orders of magnitude.

What is a slope?The slope or gradient of a line in mathematics is a numerical representation of the steepness and direction of the line.
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
To find the equation of the line that passes through the points (-4, 0) and (0, 4), we can use the point-slope form of the equation of a line as described in the definition.
First, let's find the slope of the line. We can use the formula:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) = (-4, 0) and (x2, y2) = (0, 4):
m = (4 - 0) / (0 - (-4)) = 4 / 4 = 1
So the slope of the line is 1.
Next, let's choose one of the given points, say (-4, 0), and substitute its coordinates and the slope into the point-slope form:
y - 0 = 1(x - (-4))
Simplifying this equation, we get:
y = x + 4
So the equation of the line that passes through the points (-4, 0) and (0, 4) is y = x + 4.

Answers
Answer:
Step-by-step explanation:
Ravi présent âge 15 because présent would be 20:15 and then it would turn into 25:20
Answer:
15 years old
Step-by-step explanation:
Given the ratio of their ages = 4 : 3 = 4x : 3x ( x is a multiplier )
Then in 5 years the ratio of their ages is 4x + 5 : 3x + 5 = 5 : 4, that is
[tex]\frac{4x+5}{3x+5}[/tex] = [tex]\frac{5}{4}[/tex] ( cross- multiply )
4(4x + 5) = 5(3x + 5) ← distribute both sides
16x + 20 = 15x + 25 ( subtract 15x from both sides )
x + 20 = 25 ( subtract 20 from both sides )
x = 5
Thus
Ravi's age is 3x = 3 × 5 = 15
