The ratio of the measure of the sides of a triangle is 2:3:6, and the perimeter is 187cm. What is the measure of the largest side?
The measure of the largest side of the triangle is 102cm.
What is ratio?Ratio, is a term that is used to compare two or more numbers. It is used to indicate how big or small a quantity is when compared to another. In a ratio, two quantities are compared using division.
For example, 2:3:6 shows the ratio of the sides of a triangle. The perimeter which is the addition of the triangle is 187cm.
Therefore the measure of each side will be given as:
2/11×187= 34cm
3/11×187= 51cm
6/11×187= 102cm
This means that the measure of the three sides are 34cm, 52cm, and 102cm.
Therefore the measure of the largest side is 102cm

Slope = ½; (h, k) = (1, -2) find the slope-point
The linear equation with a slope of 1/2 and that passes through the point (1, -2) is written in point-slope form as:
y = (1/2)*(x - 1) - 2
How to find the equation of the line?For a linear equation with a slope m and a known point (h, k), the slope-point form is written as:
y = m*(x - h) + k
Where y and x are the two variables.
Here we know that the slope is 1/2, and the known point is (1, -2), then the values on the equation above are:
m = 1/2
h = 1
k = -2
Replacing that in the general formula for the linear equation in the slope-point form that is written above, we will get:
y = (1/2)*(x - 1) - 2
That is what we wanted to find.

The slope of the line is found as follows;
(-5 - (-21))/(-1 - (-5)) = 4
The equation is y - (-5) = 4·(x - (-1)) = 4·x + 4
y = 4·x + 4 - 5 = 4·x - 1
y = 4·x - 1The y-intercept is (0, 4), the x-intercept is (4, 0)
The slope is therefore; (0 - 4)/(4 - 0) = -1
The equation is therefore; y - 0 = -1 × (x - 4) = -x + 4
y = -x + 4The y-intercept is (0, -1), the x-intercept is (4, 0)
The slope is therefore; (0 - (-1))/(4 - 0) = 1/4
The equation is therefore; y - 0 = (1/4) × (x - 4) = x/4 - 4/4 =

Marlene used the Distributive Property to find the product of 6 and 0.82. Which expression shows the Distributive Property?
The Distributive property on the expression gives a result of 4.9 and the distributed expression is (2 + 4) * 0.82
How to apply the Distributive property on the expression?From the question, we have the following parameters that can be used in our computation:
The expression is given as:
The product of 6 and 0.82
Mathematically, this expression can be represented as
6 * 0.82
To apply the distributive property,
We need to express 6 as the sum of two numbers
So, we have the following representation
6 * 0.82 = (2 + 4) * 0.82
Remove the brackets
6 * 0.82 = 2 * 0.82 + 4 * 0.82
Expand the terms of the expression
6 * 0.82 = 1.64 + 3.28
Evaluate the sum
6 * 0.82 = 4.92
Hence, the solution is 4.9

The domain and range of this square root function are: D: [–4, ∞) and R: [0, ∞).
What is a domain?In Mathematics, a domain can be defined as the set of all real numbers for which a particular function or relation is defined. This ultimately implies that, a domain is the set of all possible input values (x-values) for a function while a range is the set of all possible output values (y-values) of a function.
Based on the information provided, the function is represented as follows:
g(x) = √(x + 4)
Since a square root function doesn't exist for all negative values, the domain of this function is given by:
x + 4 ≥ 0
x ≥ -4
Domain = [-4, ∞]
Since we do not have a vertical translation, the range of this square root function is given by:

Step-by-step explanation:
Fill in X and Y for each of the equations until you find one that fits
The equation of the line y=2x+3 passes through the (1,4) point only.
The line gave y=2x+3.
In order to check whether the line passes through the points the following steps are:
A) (1,4)
Here x=1 , y=4.
We will put these values in the line y=2x+3.
4= 2(1)+3
4=4
As L.H.S=R.H.S, therefore this point (1,4) passes through the line.
B) (-1,4)
Here x=-1 , y=4.
We will put these values in the line y=2x+3.
4= 2(-1)+3
4= -2+3
4 [tex]\neq[/tex] 1
As L.H.S [tex]\neq[/tex]R.H.S, therefore this point (1,4) does not pass through the line.

3= 2(2)+3
3= 4+3

2= 2(3)+3
2= 6+3
