Determine whether the graphs of y =-9x+12 and y=1/3x-12 are parallel, perpendicular, coincident

Mathematics

1) graphs y = -9x + 12 and y = 1/3x - 12 are not coincident.

2) The graphs are not parallel, because the angular coefficients are not equal

3) The condition of perpendicularity:

k_1\cdot k_2=-1, where k_1=-9;~~~ k_2=\frac{1}{3}


(-9)\cdot\frac{1}{3}=-3\ne -1 - not perpendicular

Which equation represents a line parallel to the line shown on the graph?
Delicious77 [7]

The  equation y=2x+1 has the same slope , so will be parallel to the given line.

<h3>What is a linear function ?</h3>

A function that can be represented in the form of y =mx +c , is called a Linear Function.

here m is the slope and c is the y intercept.

The slope of the given line can be found as follows

The y intercept is 4

at x = -2 , y =0

0 = -2m + 4

m = 2

The line parallel to this line will have the same slope

In the given option , Option C , y=2x+1 has the same slope , so will be parallel to the given line.

Which equation represents an exponential function that passes through the point (2, 80)?
Lena [83]

The function f(x) = 5(x)⁴, and f(x) = 5(4)ˣ represents the function that passes through the point (2, 80) option second and fourth are correct.

<h3>What is an exponential function?</h3>

It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent \rm y = a^x

where a is a constant and a>1

We have; an exponential function that passes through the point (2, 80).

f(x) = 4(x)⁵

Plug (2, 80) in the abovew function:

f(2) = 4(2)⁵ = 128 (false)

f(x) = 5(x)⁴

Plug (2, 80) in the abovew function:

f(2) = 5(2)⁴ = 80 (true)

f(x) = 4(5)ˣ

f(2) = 4(5)² = 100 (false)

f(x) = 5(4)ˣ

f(2) = 5(4)² = 80 (true)

Thus, the function f(x) = 5(x)⁴, and f(x) = 5(4)ˣ represents the function that passes through the point (2, 80) option second and fourth are correct.

The system of equations graphed below has how many solutions?
Artist 52 [7]
Answer: C) 0

The lines are parallel. They never cross. To have a solution, the lines need to intersect. Each intersection is a solution. That's why there are no solutions here. The system is inconsistent.

Note how the slopes are both 1/2 while the y intercepts are different. Parallel lines have equal slopes but different y intercepts.

Y=-x <br>y=-7x<br><br>solve system of equations algebraically <br>​
snow_lady [41]

Answer:

(x,y) = (0,0)

Step-by-step explanation:

Let both as equation (1) and (2)

put equal both sides -x = -7x

-x + 7x = 0

6x = 0

x = 0

put it in 2nd equation

y = -7(0)

y = 0
