So first, you need to find the y intercept and slope of the line/function.
then, you just plug it in to y=mx+b form
this one would be:
slope of -5/4
y intercept: 2
so it would be y=-5/4+2

PLEASE I need help on these 4 problems you don’t have to do them all but if you can at least do one of them TYSM

Answer:

For right angle triangle,

we use Pythagoras theorem that is:

c^{2} =a^{2} +b^{2}

c = \sqrt{a^{2} +b^{2} }

For question 1:

c = ?

a = 40

b = 9

putting them in formula,

c = \sqrt{40^{2} + 9^{2} }

c = 41

For question 2:

c = ?

a = 12

b = 13

putting them in formula,

c = \sqrt{12^{2} + 13^{2} }

c = approximately 17.69181

For question 3:

c = 35

a = 20

b = ?

putting them in formula,

c^{2} =a^{2} +b^{2}

35^{2} = 20^{2} + b^{2}

1225 = 400 + b^{2}

b^{2} = 1225 - 400

b^{2} = 825

\sqrt{b^{2} } = \sqrt{825}

b = 5 \sqrt{33}

For question 4:

c = 37

a = 20

b = ?

putting them in formula,

c^{2} =a^{2} +b^{2}

37^{2} = 20^{2} + b^{2}

1369 = 400 + b^{2}

b^{2} = 1369 - 400

b^{2} = 969

Taking square root on both sides

b = 31.12

Hope it helps.

△DEF is mapped to △D′E′F′ using the rule (x,y)→(x,y+1) followed by (x,y)→(x,−y).
anyanavicka [17]

Answer:△DEF is congruent to △D′E′F′ because the rules represent a translation followed by a reflection, which is a sequence of rigid motions.


Step-by-step explanation:

A rigid motion of the plane  is a motion which maintain distance.

Translation is a kind of rigid motion used in geometry to trace a function that moves an object a particular distance.

A reflection is also a kind of rigid motion . It is mainly a 'toss' of a shape across the line of reflection.

So,△DEF is mapped to △D′E′F′ using the rule (x,y)→(x,y+1) ( which is a translation.) followed by (x,y)→(x,−y)(which is reflection),therefore it is a sequence of rigid motions.

I need a help with this
Anvisha [2.4K]

Answer:

130.356 g

Step-by-step explanation:

The problem tells you there is a proportional relationship, so set up a proportion and solve..

99.684 is to 11.7 as X is to 15.3

Written as a math equation like this...

99.684/11.7 = X/15.3

Now solve for X

130.356 = X    (multiply both sides by 15, then simplify)
