Answer:

y = -3x + 4

Step-by-step explanation: Substitute the numbers in for x & y to see which one is the answer.

(-1, 7):

y = -3x + 4

7 = -3(-1) + 4

7 = 3 + 4

7 = 7

TRUE


(2, -2):

y = -3x + 4

-2 = -3(2) + 4

-2 = -6 + 4

-2 = -2

TRUE


(7, -17):

y = -3x + 4

-17 = -3(7) + 4

-17 = -21 + 4

-17 = -17

TRUE


(10, -26):

y = -3x + 4

-26 = -3(10) + 4

-26 = -30 + 4

-26 = -26

TRUE


Hope this helps you!!! :)

Answer:

If we split this figure into a rectangle and triangle, we can solve:

THe rectangle would have an area of 4.14 (a=b x h) and the triangle would have an area of 8.28 (a=1/2bh)

If we add these numbers together we should have the area

a=4.14+8.28

a=12.42

In parallelogram LMNO, LM = 4.12, MN = 4, LN = 5, and OM = 6.4. Diagonals and intersect at point R. What is the length of ?
timofeeve [1]

Answer:

The length of OR = 3.12

Step-by-step explanation:

In a parallelogram:

LM = 4.12

MN = 4

LN = 5 = 2.5 (divided by 2)

OM = 6.4

where LN and OM are diagonals. We will find the length of OR.

Now by applying the Pythagorean theorem:

b = √c²-a²

OR= √(4)²-(2.5)²

OR = √16-6.25

OR = √9.75

OR = 3.12

Thus the length of OR = 3.12 ...

What is 12.95p=44 simplified to its lowest value
goblinko [34]

\huge \boxed{\mathbb{QUESTION} \downarrow}

  • What is 12.95p=44 simplified to its lowest value?

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

\sf \: 12.95p = 44

Divide both sides by 12.95.

\sf \: p=\frac{44}{12.95}  \\

Expand 44/12.95 by multiplying both the numerator and denominator by 100.

\sf \: p=\frac{4400}{1295}  \\

Reduce the fraction 4400/1295 to its lowest terms by extracting and cancelling out 5.

\boxed{ \boxed{  \bf p = \frac{880}{259} = 3\frac{103}{259} \approx 3.39}}
