Find the height of a triangle whose base is 5 inches and area is 12 square inches.
Answer:
Therefore, Height = 4.8 inches.
Step-by-step explanation:
Given : A triangle whose base is 5 inches and area is 12 square inches.
To find : Find the height of a triangle.
Solution : we have given
Triangle base = 5 inches.
Area = 12 square in.
We need to find height of the triangle.
Area = * base * height .
Plugging the values .
12 = * 5 * height .
On multiplying both sides by 2
24 = 5 * height .
On dividing both sides by 5.
Height = 4.8 inches.
Therefore, Height = 4.8 inches.

Answer:
Your answer is. a=14-3b
Hope that this is helpful. Tap the crown button, Like & Follow me
The equation of 'b' in terms of 'a' will be b = (14 - a) / 3.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
The equations are given below.
a = 3t - 10 ...1
b = 8 - t ...2
From equation 2, then we have
b = 8 - t
t = 8 - b
Put the value of t in equation 1, then we have
a = 3(8 - b) - 10
a = 24 - 3b - 10
a = 14 - 3b
3b = 14 - a
b = (14 - a) / 3
The equation of 'b' in terms of 'a' will be b = (14 - a) / 3.

The lines represented by the equations y=\frac{4}{5}x+8y= 5 4 x+8 and 20y+25x=18020y+25x=180 are
Given:
The equations of lines are
[tex]y=\dfrac{4}{5}x+8[/tex]
[tex]20y+25x=180[/tex]
To find:
The relation between two of lines.
Solution:
The slope intercept form of a line is
[tex]y=mx+b[/tex]
Where, m is slope and b is y-intercept.
We have,
[tex]y=\dfrac{4}{5}x+8[/tex] ...(i)
[tex]20y+25x=180[/tex] ...(ii)
Equation (i) can be written as
[tex]20y=-25x+180[/tex]
[tex]y=\dfrac{-25x+180}{20}[/tex]
[tex]y=\dfrac{-25x}{20}+\dfrac{180}{20}[/tex]
[tex]y=\dfrac{-5x}{4}+9[/tex] ...(iii)
On comparing (i) with slope intercept form, we get
[tex]m_1=\dfrac{4}{5}[/tex]
On comparing (iii) with slope intercept form, we get
[tex]m_2=-\dfrac{5}{4}[/tex]
Now,
[tex]m_1\times m_2=\dfrac{4}{5}\times (-\dfrac{5}{4})[/tex]
[tex]m_1\times m_2=-1[/tex]
The product of slopes of both lines is -1. We know that the product of slopes of two perpendicular lines is -1.
Therefore, the given lines are perpendicular.

Determine the domain on which of the following function is increasing
Given:
The graph of a function.
To find:
The domain on which of the following function is increasing.
Solution:
Domain is the set of x-values or input values.
From the given graph it is clear that the vertex of the given function is at (4,75).
Before the point (4,75) the graph is increasing and after the point (4,75) the graph is decreasing.
The function is defined for [tex]0\leq x\leq 9[/tex].
Since the graph is increasing when [tex]0\leq x\leq 4[/tex], therefore the function is increasing over the interval [0,4].
Therefore, the domain on which of the following function is increasing is [0,4].
After observing the x-axis points the domain of the function n whose curve is shown in the graph is [0, 9].
The domain of a curve on graph paper refers to the set of all x-values for which the curve is defined or exists.
It's the range of x-values that correspond to points on the curve.
So, the domain can be determined by looking at the x-axis and identifying the range of values that the curve.
In the given graph we can see that,
The curve lies between 0 to 9 on the x-axis.
Thus the fucntion is defined in the interval [0, 9]
Hence,
The domain of the given curve of a fucntion is [0, 9].

Step-by-step explanation:
-3x + 7y = 5x + 2y (you subtract the 2y from both sides)
-3× + 5y = 5x (then add 3x to both sides)
5y = 8x (use x = - 5)
5y = 8x - 5 = -40 (both sides are divided by 5)
y = -8

"Eight less a number is less than or equal to seventeen"
Answer:
we don't know the exact value of "a number" so we can assign it the letter value x
so we know that x-8 is less than or equal to 17
you would solve this the same way you would solve any other equation so
x is less than or equal to 25
