Show all Work; Solve using the substitution method: y=x-6 3x-2y=8

Mathematics
1 answer:
Shkiper50 [21]3 years ago
3 0

Step-by-step explanation:

y = x - 6...(1) \\  3x - 2y = 8...(2) \\ substituting \: y = x - 6 \: in \: equation \: (2) \\ 3x - 2(x - 6) = 8 \\  3x - 2x + 12 = 8 \\ x = 8 - 12 \\ x =  - 4 \\  \implies \: y = x - 6 =  - 4 - 6 =  - 10 \\  \therefore \: y =  - 10 \\ \therefore \:  \{x, \:  \: y \} =  \{ - 4, \:  \:  - 10 \}

If the line with the slope 5 that passes through the point (-1,3) intersects the x axis at a point, what are the coordinates of
Crazy boy [7]

Answer: (-8/5,0)

Step-by-step explanation: If the slope is 5, m = 5

For (-1,3) we have x₀= -1 and y₀ = 3, to find the line equation

y - y₀ = m(x - x₀)

y - 3 = 5(x - (-1))

y - 3 = 5(x + 1)

y - 3 = 5x + 5

y = 5x + 8

A P that intersects the x axis has y = 0

0 = 5x + 8

5x = -8

x = -8/5

P (-8/5,0)

Given the functions below, find (g * h)(1). g(x) = x^2 + 4 + 2x. h(x) = -3x + 2
pshichka [43]

Answer:

3

Step-by-step explanation:

g(x) = x² + 2x+4

h(x) = -3x+2

(g*h)(1) is the same as

g(h(1)) , next solve for h(1) first by substituting in h(x), x with 1

g( h( x= 1)) = g( -3*1 +2)  = g( -1) so substitute in g(x) , x with -1

g(x= -1) = (-1)² +2(-1) +4 =1-2+4 =3

Determine whether the function f(x) = -9.5 + 6 + x² is even, odd or neither.
zimovet [89]

Answer:

The function f(x) = -9.5 + 6 + x² is neither odd or even.

Step-by-step explanation:

We know that a function is termed as 'even' when

f(-x) = f(x) for all x

We know that a function is termed as 'odd' when

f(-x) = -f(x) for all x

Given the function

f(x) = -9.5x⁵ + 6 + x²

substitute x with -x

f(-x) = -9.5(-x)⁵ + 6 + (-x)²

as (-x)⁵ = -x⁵, so

f(-x) = -(-9.5x)⁵ + 6 + (-x)²

Apply exponent rule: (-a)ⁿ = aⁿ, if n is even

f(-x) = -(-9.5x)⁵ + 6 + x²

Apply rule: -(-a) = a

f(-x) = 9x⁵ + 6 + x²

As

f(-x) ≠ f(x) ≠ -f(x)

Therefore, the function f(x) = -9.5 + 6 + x² is neither odd or even.
