Find The Unknown Sizes Of Angles In The Following Figure (please Explain It):

Answers

Answer 1

Answer:

x = 56

MKL = 56

KML=  63

MLK = 61

Step-by-step explanation:

We know that the sum of the interior angles of a triangle = 180 degrees.

So, x+ (x+7)+ ( x+5) = 180

3x+ 12= 180

3x= 180-12 = 168

168/3 = x

therefore, x= 56 degrees.

So MKL = 56

KML= 56+ 7 = 63

MLK = 56+5 = 61

How many points of intersection are on the graph of the following system?

The linear-quadratic system has
(select)
points of intersection.

Answers

Answer:

2 points of interception of (3.12 , 12./12) and (-5.12 , 3.87)

Step-by-step explanation:

y − x = 9

y = x + 9

x+9 = x²+3x-7

x²+2x-16=0

x = (-2±√2²-4(1)(-16)) / 2 = (-2 ± √68) / 2 = -1 ± √17

x = 3.12 or x = -5.12

y = 12.12 or y = -3.87

20(2)^6/ 4(2)^2 ≠ 5(2)^3
20(64)/4(4)≠ 5(8)
1280/16≠40
80≠40
When dividing exponents we do not divide, (Ik confusing) we actually subtract so instead of us thing the answer it 5x^3 we actually look at the equation, 20x^6/4x^2 (6-2=4)= 5x^4
When we work that out we get
20(2)^6/4(2)^2=5(2)^4
20(64)/4(4)=5(16)
1280/16=80
80=80

Answer:

In the step-by-step explanation!!!

Step-by-step explanation:

(a)

20(2)^6 ÷ 4(2)^2 = 80

5x^3 = 40

And we of course know that 80 is not equal to 40 at all.

(b)

5x^4 should be the answer

Natasha has a job putting letters in envelopes to be mailed. in 1 hour she put 42 letters in envelopes. which equation best represents y, the total number of letters natasha puts in envelops in x hours if she continues

Answers

Answer:

36 pages .394kb

Step-by-step explanation:

that's it well done

You can use multiplication along with converting statements to symbols.

The equation for the given condition is given by [tex]y = 42x[/tex]

where y represents the total number of letters Natasha puts in envelops in x hours.

How to form symbolic expressions from the description?

You need to know how to convert the statement to symbolic expression.

Suppose if it is said that a thing is increased by 4,then we write it as

that thing + 4

Suppose if it is written that 'x' objects are sold on p price per object. Since 1 object is sold at p price, then x objects will be sold at:

[tex]p + p + ... + p \: \: \: (x \: \: times) = p \times x[/tex]

Such conversion can help us to form symbolic expressions from the given description.

Since for the given case, in 1 hour, Natasha put 42 letters in envelopes, then in x hour she will put:

[tex]42 + 42 + ... + 42 \: \: (x \: times) = 42 \times x[/tex]

Since in x hours, she puts y envelopes but envelopes put in x hours came out as 42 times x, thus, both the values are equal, or

[tex]y = 42 \times x = 42x \text{\:\:(written in short)}[/tex]

The equation for the given condition is given by [tex]y = 42x[/tex]

where y represents the total number of letters Natasha puts in envelops in x hours.

John has 15 1/4 gallons of gas in his truck. John can drive his truck 7 1/2 miles on each gallon of gas. About how many miles can John drive his truck

Answers

Answer:

114 3/8 gallons

Step-by-step explanation:

To solve the question, we multiply by the number of gallons and the amount travelled per gallon:

Let's convert all fractions to improper fractions:

15 1/4 = (15*4 + 1)/4 = 61/4

7 1/2 = (7*2 + 1)/2 = 15/2

Multiply the numerators and the denominators:

61/4 * 15/2 = 61*15/4* 2 = 915/8 = 114 3/8

Write the equation of the line in fully simplified slope intercept form

Answers

Y= -1/2-7
Slope intercept form is y=mx+b
‘m’ is your slope and ‘b’ is your y-intercept !

Answer:

y = -0.5x - 7 or y = -1/2x - 7 (both are same)

Step-by-step explanation:

m = slope

slope = y2 - y1 / x2 - x1

-9 - (-8) / 4 - 2 = -1/2 = -0.5

m = -0.5 

b = y-intercept

b = -7

y = mx + b

y = -0.5x + (-7)

y = -0.5x - 7
