Answer: x = 30 (choice 3)

---------------------------------------------------------

To get this answer, you set the two expressions equal to one another, then you isolate x. Recall that vertical angles are congruent.

x+90 = 4x

x+90-x = 4x-x .... subtract x from both sides

90 = 3x

3x = 90

3x/3 = 90/3 ... divide both sides by 3

x = 30

Now let's check the answer

x+90 = 4x

30+90 = 4*30 ... replace every x with 30

120 = 120

The last equation is true so the answer is confirmed.

Answer:

Mark answer C and D as correct

Step-by-step explanation:

Recall that a bisector cuts the side in two equal segments, then KH has to be half of 136 that is KH = 68

Also KHZ and HLZ are right angle triangles that share the same hypotenuse, so they are congruent triangles, which means that HL must equal KH  and therefore the full side HJ must be 68 times 2 = 136

Three runners in a relay race share the 8-mile distance equally. How many miles does each runner travel?
Serggg [28]

Answer: 2 2/3 miles

Step-by-step explanation:

From the question, we are informed that three runners in a relay race share the 8-mile distance equally.

The number of miles that each runner travel will be the total miles divided by number of runners. This will be:

= 8/3

= 2 2/3 miles

Y+4x=10x-6 solve for x
7nadin3 [17]

Answer:

(y-6)/6 = x

Step-by-step explanation:

y+4x=10x-6

Subtract 4x from each side

y+4x-4x=10x-4x-6

y = 6x-6

Add 6 to each side

y +6 = 6x-6+6

y+6 = 6x

Divide by 6

(y-6)/6 = 6x/6

(y-6)/6 = x

F(x) = { -2x -1, x ≤ 2
Degger [83]

Answer:

Use the appropriate entry method for piecewise functions for the graphing calculator of interest.

Step-by-step explanation:

For Desmos, the entry looks like ...

f(x) = {x ≤ 2: -2x-1,-x+4}

_____

For a TI-84 calculator, the entry may look like ...

Y₁ = (-2X–1)(X≤2) + (-X+4)(X>2)

The symbols ≤ and > come from the TEST menu, which is the (2nd) shift of the MATH key.

Note that the function is the sum of the pieces, each piece multiplied by a test. For something like 0≤x<2, the multiplier would be a pair of tests:

... (0≤X)(X<2)
