Find the slope using points ( 7,-3) and (11,-4)

Answers

Answer:

1/4

Step-by-step explanation:

Answer:

m = [tex]-\frac{1}{4}[/tex]

Step-by-step explanation:

Use the following equation:

slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

Let:

[tex](x_1 , y_1) = (11 , -4)\\(x_2 , y_2) = (7 , -3)\\[/tex]

Plug in the corresponding numbers into the corresponding variables:

slope (m) = [tex]\frac{-3 - (-4)}{7 - 11} = \frac{-3 + 4}{7 - 11} = \frac{1}{-4} = -\frac{1}{4}[/tex]

[tex]-\frac{1}{4}[/tex] is your answer.

Question:

[tex]\triangle[/tex]HLI is shown. Line segment JK is drawn near point L to create [tex]\triangle[/tex]JLK. If [tex]\triangle[/tex]HLI ~ [tex]\triangle[/tex]JLK by the SSS similarity theorem, then [tex]\frac{HL}{JL} =\frac{IL}{KL}[/tex] is also equal to which ratio?

Answer:

[tex]\frac{H I}{J K}[/tex]

Step-by-step explanation:

Given

HLI ~ [tex]\triangle[/tex]JLK

[tex]\frac{HL}{JL} =\frac{IL}{KL}[/tex]

Required

Which other ratio equals [tex]\frac{HL}{JL} =\frac{IL}{KL}[/tex]

[tex]\triangle[/tex]HLI ~ [tex]\triangle[/tex]JLK  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

[tex]\frac{HL}{JL} = \frac{IL}{KL} = \frac{HI}{JK}[/tex]

So, from the list of options

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

Answer: 52.5cm²

Step-by-step explanation:

Firs, you have to split this composite shape into two separate shapes; a rectangle and triangle.

To work out the area of the rectangle you would have to do 8x5=40.

To work out the area you would have to find out the height of it first. So, to do this you would have to do 1+2=3 then do 8-3=5. Now we know the height is 5.

Then you have to use the formula base times height divided by 2 (b×h/2). So 5×5=25 then 25÷2=12.5

To then find the total area of this composite shape you would have to add the two areas together. So 40+12.5=52.5cm²
