find the value of x in the triangle shown below

Answer:

−15+43

Step-by-step explanation:

1. Add the numbers

= 3−14x−x+25+15

= 43−14−

2. Combine like terms

= 43−14x−x

= 43−15

3. Rearrange terms

= 43−15x

= −15+43

  b) x < -4

Step-by-step explanation:

Eliminate parentheses and you have ...

  -12 > 3x . . . . . . . . subtract 4x+16

  -4 > x . . . . . . . . divide by 3

The maximum or minimum of a quadratic function is found evaluating the polynomial at [tex]x = -\frac{b}{2\cdot a}[/tex].

A quadratic function is an algebraic function of the form:

[tex]y = a\cdot x^{2}+b\cdot x + c[/tex], [tex]\forall \,x, y, a, b, c\,\in \mathbb{R}[/tex] (1)

Where:

The maximum/minimum of a quadratic function is represented graphically by the vertex, which is the only point that has no a "twin" point by any means of symmetry. We can get the x-coordinate of the vertex by means of the quadratic formula:

[tex]a\cdot x^{2} + b\cdot x + (c- y) = 0[/tex] (2)

[tex]x = \frac{-b\pm \sqrt{b^{2}-4\cdot a\cdot (c-y)}}{2\cdot a}[/tex], where [tex]b^{2}-4\cdot a\cdot (c-y) = 0[/tex].

Hence, the x-coordinate of the vertex is:

[tex]x = -\frac{b}{2\cdot a}[/tex] (3)

And the y-coordinate of the vertex is determined by evaluating (1) at (3):

[tex]y = f\left(-\frac{b}{2\cdot a} \right)[/tex] (4)

The maximum or minimum of a quadratic function is found evaluating the polynomial at [tex]x = -\frac{b}{2\cdot a}[/tex].

Answer:

Step-by-step explanation:

Answer: 100 99/100

Step-by-step explanation: add the 1/2 and 1/5 together by finding a common denominator(10). 1/2 would become 5/10 and 1/5 would become 2/10. 2/10 + 5/10 =7/10. now we're left with (7/10)^2 +3/10 x 5

to do (7/10)^2 you square the top and bottom to give you 49/100.

next we'll do 3/10 x 5 which would equal 15/10. so now all we have left to do is add 49/100 and 15/10. to do this we'll find a common denominator of 100. so well multiply the top and bottom by 10 to give you 150/100.

finally, 49/100 + 150/100 = 199/100 or as a mixed number, 100 99/100

Answer:

1[tex]\frac{99}{100}[/tex]

Step-by-step explanation:

I would start by turning the parentheses fractions into one fraction.

You could do binomial multiplication and get [tex]a^{2} +2ab+b^{2}[/tex] but it might take longer.

So I would just turn them into one fraction by finding the common denominator.

The common denominator here is 10

[tex]\frac{1}{5} (\frac{2}{2} )=\frac{2}{10}[/tex]

[tex]\frac{1}{2} (\frac{5}{5} )=\frac{5}{10}[/tex]

Now add

[tex]\frac{2}{10} +\frac{5}{10} =\frac{7}{10}[/tex]

Now apply: [tex](\frac{a}{b} )^{2} =\frac{a^{2} }{b^{2} }[/tex]

[tex](\frac{7}{10} )^{2} =\frac{7^{2} }{10^{2} } =\frac{49}{100}[/tex]

Now, multiplying the other fraction we get [tex]\frac{3}{10} (5)=\frac{15}{10}[/tex]

Now turn this into a fraction with denominator 100 to add the two fractions

[tex]\frac{15}{10} (\frac{10}{10} )=\frac{150}{100}[/tex]

[tex]\frac{49}{100} +\frac{150}{100} =\frac{199}{100} =1\frac{99}{100}[/tex]

There is also another method to add or subtract fractions without multiplying to get a common denominator in case you are interested:

[tex]\frac{a}{b}[/tex]±[tex]\frac{c}{d}[/tex]=[tex]\frac{ad+bc}{bd}[/tex]

Answer: 86 degree

Step-by-step explanation:

The Straight line is 180 degrees so if we minus 180 by the outward degree there will be the degree for inward degree

P: 95 degrees T: 160 degree S: 88 degrees R: 91 degree

The degree for the pentagon is 540 degrees so If I minus 540 by all the four inward degrees there will be the missing last degree

95 + 160 + 88 + 91 = 434 degree

540 - 434 = 106 degree

180 - 106 = 94 degree

So the last inward degree is 94

Finally, if I minus 180 by 94 (the way I used to find inward degree and to find outward degree for now) it equals 86 degree

so X is 86 degree

Sorry if this was too confusing:)

Answer:

1st--> x=135

2nd-->x=74

Step-by-step explanation:

1st:

triangle =180°

180-90=90

90÷2=45

straight line=180°

180-45=135

therefore x=135°

2nd:

pentagon=540°

straight line=180°

180-92=88 for line s

180-20=160 for line q

180-85=95 for line p

180-89=91 for line r

160+95+88+91=434

540-434=106

180-106=74

therefore x=74°

Answer:

X=22° ; Exterior Angle = 125°

Step-by-step explanation:

The exterior angle theorem states that the exterior angle of a triangle is equal to the sum of the two opposite interior angles.

(2x) + (103 - x) = (6x - 7)

103 + 7 = 6x - 2x + x

110 = 5x -->(Divided by 5)--> x=22°

6(22) - 7 = 125°

Based on the temperature change and the amount of time it did so, the average change in temperature per hour is -3.5°F.

The average change in temperature per hour can be found by:

= Temperature change / Number of hours

Solving would give:

= -23.8 / 6.8

= -3.5°F

We can therefore conclude that in every hour of this cold day, the temperature changed by an average of -3.5°F.

The second graph represents a linear function since, it has a constant rate of change (slope)

Answer:

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection)
