ΔRSP ≅ ΔQSP by SAS. Therefore, PR ≅ PQ by CPCTC theorem.

If two triangles are congruent, the CPCTC theorem states that all corresponding parts of the two triangles would also be congruent to each other.

Since S is the midpoint of QR, therefore, RS ≅ QS (one pair of congruent sides)

∠RSP ≅ ∠QSP [right angles] (one pair of congruent included angles)

SP ≅ SP based on the reflexive property (one pair of congruent sides)

Therefore, ΔRSP ≅ ΔQSP by SAS.

Answer:

The equation of the line that passes through the points (2a, b) and (a, b+1) is [tex]$y=-\frac{1}{a} x+2+b$[/tex].

Step-by-step explanation:

The given points are (2a, b) and (a, b+1).

It is required to find the equation of the line that passes through the points. the slope-intercept form.

Step 1 of 4

Using the given two points, to find the slope.

Given points are (2a, b) and (a, b+1).

Substitute [tex]$x_{1}[/tex]=2a,

[tex]$$\begin{aligned}&y_{1}=b \\&x_{2}=a \text { and } \\&y_{2}=b+1\end{aligned}$$[/tex]

into the formula, [tex]$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$[/tex]

Step 2 of 4

Simplify [tex]$m=\frac{b+1-b}{a-2 a}$[/tex], further

[tex]$$\begin{aligned}m &=\frac{b+1-b}{a-2 a} \\m &=-\frac{1}{a}\end{aligned}$$[/tex]

As a result, the slope is [tex]$m=-\frac{1}{a}$[/tex].

Step 3 of 4

Use the slope [tex]$m=-\frac{1}{a}$[/tex] and the coordinates of one of the points (2a, b) into the point-slope form, [tex]$y-y_{1}=m\left(x-x_{1}\right)$[/tex].

Substitute [tex]$m=-\frac{1}{a}$[/tex],

[tex]x_{1}=2 a$ and$y_{1}=b$[/tex]

into the formula, [tex]$y-y_{1}=m\left(x-x_{1}\right)$[/tex]

[tex]$y-b=-\frac{1}{a}(x-2 a)$[/tex]

[tex]$y-b=-\frac{1}{a} x+2$$[/tex]

Step 4 of 4

Rewrite the above equation as a slope-intercept equation. So, from the above term [tex]$y-b=-\frac{1}{a} x+2$[/tex], Add b on each side.

[tex]$$\begin{aligned}&y-b=-\frac{1}{a} x+2 \\&y=-\frac{1}{a} x+2+b\end{aligned}$$[/tex]

Therefore, the equation of the line that passes through the points is [tex]$y=-\frac{1}{a} x+2+b$[/tex].

Answer:

? = 45

Step-by-step explanation:

the inner and outer triangles are similar ( AA postulate )

Then the ratios of corresponding sides are in proportion, that is

[tex]\frac{56}{56+24}[/tex] = [tex]\frac{105}{105+?}[/tex]  , that is

[tex]\frac{56}{80}[/tex] = [tex]\frac{105}{105+?}[/tex] ( divide numerator/denominator by 8 to simplify left side )

[tex]\frac{7}{10}[/tex] = [tex]\frac{105}{105+?}[/tex] ( cross- multiply )

7(105 + ? )  = 1050 ← distribute parenthesis on left side

735 + 7? = 1050 ( subtract 735 from both sides )

7? = 315 ( divide both sides by 7 )

? = 45

Answer:

151°

Step-by-step explanation:

The above shape is a quadrilateral.

The exterior angles are :

82°, 70°, 62°, and (x -5)°

Therefore,

82 + 70 + 62 + x - 5 = 360

214 -5 + x = 360

209 + x = 360

x = 360 - 209

x = 151°

1) Because [tex]\angle AOC[/tex] is a central angle, the answer is 50 degrees.

2) By the inscribed angle theorem, the answer is 25 degrees.

The 95% confidence interval of voters not favoring the incumbent is (0.0706, 0.1294).

Sample size, n=400

Sample proportion, p = 40 / 400

= 0.1

We use normal approximation, for this, we check that both np and n(1-p) >5.

Since n*p = 40 > 5 and n*(1-p) = 360 > 5, we can take binomial random variable as normally distributed, with mean = p = 0.1 and standard deviation  = root( p * (1-p) /n )

= 0.015

For constructing Confidence interval,

Margin of Error (ME) =  z x SD = 0.0294

95% confidence interval is given by Sample Mean +/- (Margin of Error)

0.1 +/- 0.0294 = (0.0706 , 0.1294)

The value of x from the given equation is 5/3

Since the three points are collinear to U, they are on a straight line which equals 0

Then we have,

UM + UD =  MD

5x+30 + 10x+20 = 3x+80

Collect like terms

5x + 10x + 50 = 3x + 80

15x - 3x = 80 - 50

12x = 30

x = 30/12 = 15/6 = 5/3

Answer:

x=22

Step-by-step explanation:

7x+6=160.

Lets start by moving 6 over to the other side. We can do this by subtracting 6 from both sides of the equation.

7x+6-6=160-6

7x=154

Now, let's isolate x by getting rid of the 7. The 7 is being multiplied with x, so to get rid of it we have to divide both sides by 7.

7x/7 = 154/7

x=22

Look Below :

Step-by-step explanation:

160 - 6 = 7x

154 = 7x

Or

7x = 154

x = 22

Answer:

1/5

Step-by-step explanation:

The slope-intercept form looks like [tex]y=mx+b[/tex] where b is the y-intercept and m is the slope. m is the slope because if you increase x by 1, the value y increases by m, and if you increase x by 1 again, the y-value will increase by the value of m, because it's being multiplied. b is the y-intercept since the y-intercept is when x=0 so mx will become m(0) which is just 0 leaving b by it self. In this case you have y=1/5x so if you were to start with 0 as x the value of y is 0. Now increase it by 1 so x becomes 1, the value of y becomes 1/5x, now increase it by 1 again so x becomes 2, the value of y is 2/5x, so as you can see the function is just increasing by 1/5 so that's the slope, so essentially whatever the coefficient of x is (the number in front of the variable x), is the slope

-------------------------------------------------------------------------------------------------------------

Given:  [tex]\textsf{y = 1/5x}[/tex]

Find: [tex]\textsf{The slope of the line}[/tex]

Solution:  In order to determine the slope of the line we need to see how the slope-intercept form compares to this expressions.  The slope-intercept form is y = mx + b where m is the slope and b is the y-intercept.  In this case we have no y-intercept therefore we do not have a b. However, our slope is equal to 1/5 as it fits perfectly with the form that was provided.

A function is an abecedarian notion in mathematics and computer programming. In both contexts, a function is a regulation or relationship that maps input values to corresponding output values.

Step-by-step explanation:

Let x be the number of pencils bought.

Let y be the number of pens bought.

Given information from the question:

x = y - equation 1

2.9y - 1.2x = 32.30 - equation 2

From here we can use the substitution method in solving simultaneous equations to find x and y. We will substitute equation 1 into equation 2.

2.9y - 1.2y = 32.30

1.7y = 32.30

y = [tex]\frac{32.3}{1.7} \\= 19[/tex]

Step-by-step explanation:

x + y = 8

1/x + 1/y = 8/15

From first equation  y = 8 - x so

1/x + 1 / (8-x) = 8/15

Multiply through by the LCM 15x(8-x):-

15(8 - x) + 15x =  8x(8-x)

120 - 15x + 15x = 64x - 8x^2

8x^2 - 64x + 120 = 0

x^2 - 8x + 15 = 0

(x - 3)(x - 5) = 0
