Solve this system of equations using the substitution method.

miskamm [114]

Answer:

(5,14)

Step-by-step explanation:

4x-6=2x+4 because I chose any of the y values

change of subjects ⬇️

4x-2x =4+6

2x=10

2x÷2 and 10÷2

⬆️ making x stand alone

x= 5

put x into any of the equation

y=2(5)+4

y= 10+4

y=14

The ratio of the lengths of a triangle are 4:6:9 and its perimeter is 57cm. Find the length of the shortest side.

sergeinik [125]

Answer:12cm

Step-by-step explanation:

The ratio are:

4:6:9

Perimeter=57cm

Let a be the unknown value.

The triangle has three sides: 4a, 6a, 9a

Perimeter=The sum of three sides

57=4a + 6a +9a

57=19a

Divide both side by 19

a=57/19

a=3

Therefore

4a:6a:9a

4×3:6×3:9×3

12:18:27

So the shortest side is 12cm

If f(x) and its inverse function, f Superscript negative 1 Baseline (x), are both plotted on the same coordinate plane, where is

bearhunter [10]

Answer:

(2,2)

Step-by-step explanation:

step 1

Find the equation of f(x)

is a line that passes through the points (0,6) and (3,0)

Find the slope

$m=(0-6)/(3-0)=-2$

The function f(x) in slope intercept form is equal to

$f(x)=-2x+6$

step 2

Find the inverse

Let y=f(x)

$y=-2x+6$

Exchange the variables x for y and y for x

$x=-2y+6$

Isolate the variable y

$2y=-x+6$

$y=-0.5x+3$

Let

$f^{-1}(x)=y$

$f^{-1}(x)=-0.5x+3$

step 3

Solve the system of equations

$f(x)=-2x+6$

$f^{-1}(x)=-0.5x+3$

equate both functions

$-0.5x+3=-2x+6$

solve for x

$2x-0.5x=6-3$

$1.5x=3$

$x=2$

substitute the value of x in any of the functions

$f(x)=-2(2)+6=2$

The solution is the point (2,2)

therefore

Their point of intersection is (2,2)
