Answer:
See answer below
Step-by-step explanation:
Given the functions f(x) = 5x – 3 and g(x) = 2x2 - 5, find the following functions.
a)(fog)(x) = f(g(x))
f(g(x)) = f(2x^2-5)
f(g(x)) = 5(2x^2-5) - 3
f(g(x)) = 10x²-25-3
f(g(x)) = 10x² - 28
b) g(f(x)) = g(5x-3)
g(f(x)) = 2(5x-3)²-5
g(f(x)) = 2(25x²-30x+9)-5
g(f(x)) = 50x²-60x+18-5
g(f(x)) = 50x²-60x+13
c)(fog)(2) = f(g(2))
f(g(x)) = f(2x^2-5)
f(g(2)) = 10(2)² - 28
f(g(2)) = 10(4)-28
f(g(2)) = 12
d) g(f(x)) = g(5x-3)
g(f(x)) = 2(5x-3)²-5
g(f(x)) = 50x²-60x+13
g(f(2)) = 50(2)²-60(2)+13
g(f(2)) = 200-120+12
g(f(2)) =80+12
g(f(2)) = 92

If we assume the two scale factors are related, then 1:10 is half of 1:20, so half of 3:2 is 1.5:1.
Solve the system 8y-5z=23 3y-2z=6
100 POINTS
Answer:
z = 21 ; y= 16
Step-by-step explanation:
first of all we have to isolate a variable.
In second expression we can obtain:
3y = 2z+6
y = 2/3 z + 2
now we have to substitute this value in the first equation and solve it
8(2/3z+2)-5z = 23
16/3z + 16 -5z = 23
16z +48 - 15z = 69
z = 21
now we have to substitute z in the second equation:
y = 2/3 (21) +2
y = 14+ 2 = 16
y = 16

What is the distance between the points (-6, 2) and (-4, 7)? Round to the nearest tenth if necessary.
Answer: distance is 5.4
Step-by-step explanation: distance between points (X1,y1) and (x2,y2) is
√(x2-X1)² + (y2-y1)² = √[(-4-(-6))² + (7-2)²] = √(2²+ 5²) =√29
The distance between the points (-6, 2) and (-4, 7) is 5.4 units.
What is the distance formula?The distance between any two points (x₁, y₁) and (x₂, y₂) can be determined using the distance formula according to which,
Distance = √((x₂ - x₁)² + (y₂ - y₁)²).
How do we solve the given question?We are asked to find the distance between the points (-6, 2) and (-4, 7).
We will determine the distance using the distance formula, by which
Distance = √((x₂ - x₁)² + (y₂ - y₁)²)
or, Distance = √(((-4) - (-6))² + (7 - 2)²)
or, Distance = √((-4 + 6)² + (7 - 2)²) = √(2² + 5²) = √(4 + 25) = √29
∴ Distance = √29 = 5.385165 = 5.4 (rounding to the nearest tenth).
∴ The distance between the points (-6, 2) and (-4, 7) is 5.4 units.

What is the distance between these two points?
Answer:
Step-by-step explanation:
The two points are (-6,8) and (8,0)
we can find the distance thanks to this formula
√(x1-x2)^2 + (y1-y2)^2 where x and y indicate the coordinates of the two points
√(-6-8)^2 + (8)^2 = √196 + 64 = √260 ≃ 16,12

Answer:
x = -6
Step-by-step explanation:
We have the equation 3x - 4 = 2x - 10 and are asked to find "x".
To solve , we need to get "x" alone entirely.
3x - 4 = 2x - 10
Subtract 2x from both sides :
x - 4 = -10
Add 4 to both sides to get our answer :
x = -6

The graph shows one of the linear equations for a system of equations. Which equation represents the second linear equation for the system of equations that has the solution which corresponds to a point at (6, -2)?
A. 1/3x + 3y = 4
B. 1/3x + 4y = -4
C. 1/3x + 2y = -2
D. 1/3x + 2y = 2
Answer:
C. 1/3x + 2y = -2
Step-by-step explanation:
Using the point slope form of an equation
y-y0 = m(x-x0)
Get the slope m
Get the x and y intercept of the equation
Using the expression 1/3x + 2y = -2
x intercept occurs at y = 0
1/3x + 0 = 2
1/3 x = 2
x = 3 * 2
x = 6
y intercept occurs at x = 0
0+ 2y = 2
2y = -2
y = -1
Hence the required equation is C. 1/3x + 2y = -2
