Answer:
A linear function can be written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
If this line passes through the points (x₁, y₁) and (x₂, y₂), then the slope is:
a = (y₂ - y₁)/(x₂ - x₁)
We know that line f(x) passes through points (5, 0) and (10, 10)
Then the slope of f(x) is:
a = (10 - 0)/(10 - 5) = 10/5 = 2
then:
f(x) = 2*x + b
again, knowing that f(10) = 10 (because this line passes through point (10, 10) )
10 = 2*10 + b
10 = 20 + b
10 - 20 = b = -10
Then the equation of this line is:
f(x) = 2*x - 10
Now for g(x) we know that it passes through (-3, 0) and (2, 10)
then the slope is:
a = (10 - 0)/(2 - (-3)) = 10/5 = 2
g(x) = 2*x + b
And knowing that g(2) = 10 (because this line passes through point (2, 10) )
10 = 2*2 + b
10 = 4 + b
10 - 4 = b
6 = b
then:
g(x) = 2*x + 6
Then the equations are:
f(x) = 2*x - 10
g(x) = 2*x + 6
A) One transformation may be a vertical translation, and the other can be a horizontal translation.
This is a vertical translation, which is defined as:
For a function f(x), a vertical translation of k units is written as:
g(x) = f(x) + k
If k is positive, the translation is upwards
if k is negative, the translation is downwards.
And an horizontal translation of k units is written as:
g(x) = f(x - k)
if k is positive, the translation is to the right
if k is negative, the translation is to the left.
B)
For the vertical translation we have:
g(x) = f(x) + k
2*x + 6 = 2*x - 10 + k
6 = -10 + k
6 + 10 = k
16 = k
For the horizontal translation we have:
g(x) = f(x - k)
2*x + 6 = 2*(x - k) - 10
2*x + 6 = 2*x - 2*k - 10
6 = -2*k - 10
6 + 10 = -2*k
16 = -2*k
16/-2 = k
-8 = k
C)
The transformations are:
g(x) = f(x) + 16
or
g(x) = f(x - (-8))

2.5 mm
Step-by-step explanation:
A paved walkway around a garden has an outer diameter of 80 ft and an inner diameter of 40 ft. A diagram is shown below.
What is the approximate area of the paved walkway?
Given:
Outer diameter = D = 80 ftInner diameter = d = 40 ftSo,
Outer radius = R = D/2
=> R = (80 ft)/2
=> R = 40 ft
Inner radius = r = d/2
=> r = (40 ft)/2
=> r = 20 ft
Area of paved pathway = πR² - πr²
= π(R² - r²)
= π(R + r)(R - r)
= π(40 + 20)(40 - 20) ft²
= π(60)(20) ft²
= 3.14 * 1200 ft²
= 3768 ft²

Answer:
x=121°
Step-by-step explanation:
the sum of angles in a triangle always equal 180°
that means that 22°+37°+x°=180°
so we solve the equation by isolating the variable
add 22 and 37 together
59°+x°=180°
subtract 59 from both sides
x=121°
that means that x is 121 degrees
hope this helps!
Find the missing side round your answer to the nearest tenth
Answer:
x ≈ 14.7
Step-by-step explanation:
Assuming the triangle is right then use Pythagoras' identity.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 15² = 21²
x² + 225 = 441 ( subtract 225 from both sides )
x² = 216 ( take the square root of both sides )
x = [tex]\sqrt{216}[/tex] ≈ 14.7 ( to the nearest tenth )

Which expression is the equivalent to 23 1/2?
Answer:
Step-by-step explanation:
Recall that the quantity 25^(1/2) with fractional exponent 1/2 can be rewritten in the equivalent √25. In other words, the exponential form
25^(1/2) has the same value (outcome) as does √25.
In general, b^(1/a) is equivalent to (index a root of b).
[tex]\sqrt{23}[/tex] is the equivalent expression of [tex]23^{\frac{1}{2} }[/tex]
What is Expression?An expression is combination of variables, numbers and operators.
Equivalent expression is the expression whose value will be same when we simplify.
The given expression is Twenty three power one by two.
[tex]23^{\frac{1}{2} }[/tex]
By the exponential property.
Root of twenty three is expression equivalent to twenty three power of one by two.
[tex]\sqrt{23}[/tex]

Y=6-x In this case, what would be the slope and y-intercept? I'm having a hard time trying to get it to the y=mx+b format.
Answer:
Slope = [tex]\frac{-1}{1}[/tex] or -1
y = 6
Step-by-step explanation:
The equation given (y = 6 - x) is the same as saying
y = -1x + 6
Since we have a negative x variable and a positive 6 and would also be graphed the same. The only difference is that the second equation I just mentioned resembles the y = mx + b expression more. In this case the slope would be
Slope = [tex]\frac{-1}{1}[/tex] or -1
While the y-intercept would be
y = 6 - x
y = 6 - 0
y = 6

mark brainliest please :)
Answer:
A) (1, 2)
Explanation:
The origin is (0, 0), where the y-axis and the x-axis intercept (the two lines). You find the coordinates by measuring the point's distance on the both lines from the origin. On the x-axis, (horizontal, the one that goes from left to right) the point is 1 unit to the right, so the x is 1. On the y-axis (vertical, the one that goes from up to down), the point is 2 units to the right, so y is 2. The combined coordinate is (1, 2).

The mall is 6 miles west of the highway. The hospital is 12 miles west of the mall. How far, and in what direction, is the hospital from the highway?
Answer: 18 miles west
Step-by-step explanation:
The mall is west of the highway.
The hospital is then west of the mall.
If the hospital is west of the mall which is already to the west of the highway, the Hospital must be west of the highway as well.
The hospital is 12 miles west of the mall which is then 6 miles west of the highway. As they are both west, it is a continuous distance and we can simply add their distances up and assume the distance is linear.
The distance between the hospital and the highway is therefore:
= 12 + 6
= 18 miles west

If the hypotenuse of a right triangle is 8 and one leg is 6, what is the length of the other leg?
Answer:
5.3
Step-by-step explanation:
pythagorean theory :,)
[tex]a^{2} + b^{2} = c^{2}[/tex]
the legs are [tex]a[/tex] and [tex]b[/tex], while the hypotenuse (the longest side) is [tex]c[/tex]
fill in the equation with the information u have and simplify so
[tex]a^{2} + 6^{2} = 8^{2}[/tex]
[tex]a^{2} + 36 = 64[/tex]
now get the variable ([tex]a[/tex]) by itself
[tex]a^{2} + 36 = 64\\[/tex]
(subtract 36 on both sides)
[tex]a^{2} = 28[/tex]
[tex]a = 5.3[/tex]
square root of both sides ≈ 5.3
(you could also multiply the square root of 7 by 2)
