TTriangle H L I is shown. Line segment J K is drawn near point L to create triangle J L K. If △HLI ~ △JLK by the SSS similarity
pishuonlain [190]

Question:

\triangleHLI is shown. Line segment JK is drawn near point L to create \triangleJLK. If \triangleHLI ~ \triangleJLK by the SSS similarity theorem, then \frac{HL}{JL} =\frac{IL}{KL} is also equal to which ratio?

\frac{H I}{J K}      \frac{H J}{J L}     \frac{I K}{K L}     \frac{J K}{H I}      

Answer:

\frac{H I}{J K}

Step-by-step explanation:

Given

HLI ~ \triangleJLK

\frac{HL}{JL} =\frac{IL}{KL}

Required

Which other ratio equals \frac{HL}{JL} =\frac{IL}{KL}

\triangleHLI ~ \triangleJLK  implies that:

HL, IL and HI corresponds to JL, KL and JK respectively.

So, the possible ratios are:

HL : IL : HI = JL : KL : JK

Convert to fractions

\frac{HL}{JL} = \frac{IL}{KL} = \frac{HI}{JK}

So, from the list of options

\frac{H I}{J K} is equivalent to \frac{HL}{JL} =\frac{IL}{KL}

4x - 2y = -14<br> 3х - у = -8
oksian1 [2.3K]

are you trying to add them all together if so here how that would work

4x-3x=1x

2y-(1)y =1y(if the y is alone theirs a 1 always infront of it)

-14-8=-22

To the nearest tenth the value of x that satisfies 2x = −2x + 11 is
Anuta_ua [19.1K]
To solve for variable equations or inequalities, we want to do two things:
1. Reduce one side to variables only
2. Reduce that side to the variable without coefficients.

The given equation is 2x=-2x+11.

Let's perform step 1: reducing one side to variables only. By adding 2x to both sides of the equation, we get 4x=11.

Now let's perform step 2: reducing that side to the variable without coefficients. Since the coefficient of 4x is 4, we need to divide both sides of the equation by 4: x=\frac{11}{4}=2.75. Rounded to the nearest tenth, x=2.8.

So the value of x that satisfies 2x=-2x+11 is x=2.8.

What is the output, or y-value, when you input x = -3 into the function: x² − 3x + 1
Citrus2011 [14]

Answer:

y = 19

Step by step explanation:

y = x ^{2}  - 3x + 1 \\  y = ( - 3) ^{2} - 3( - 3) + 1 \\ y = 19 \\ so \: the \: y - value \: is \: 19
