15x-5=1
5x-15y=1
5x-15y=-1

Answer:

Given - A circle with centre at O .

To Prove - angle poq = 2 angle paq .

Proof - angle poq = angle paq -------- 1.

Similarly :

POQ =2 PBQ

From 1

2 PBQ = 2 PAQ

Angle PBQ = Angle PAQ .

Answer:

Step-by-step explanation:

3y+7=2x

3y=2x-7

y=(2/3)x-7/3

when parallel, the y=ax+b, the a keeps the same

so it‘s y=(2/3)x-a

and it pass (2,6), so 6=(2/3)*2 -a

6=4/3-a

-a=(18-4)/3

-a=14/3

a=-14/3

The equivalent exponential expression using 2 as

a base will be:  

Step-by-step explanation:

Given the expression

[tex]2^4\cdot \:2^5[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}[/tex]

so the expression becomes

[tex]2^4\cdot \:2^5=2^{4+5}[/tex]

            [tex]=2^9[/tex]

Therefore, the equivalent exponential expression using 2 as

Answer:

9

Step-by-step explanation:

since 9.48683298051 is the square root of 90 and has a 4 in the tenths number and since 4 isnt bigger than 5 i would say it rounds to 9

Answer:

9

Step-by-step explanation:

[tex]\sqrt{90} \\As\ 90\ is\ closer\ to\ 81\ more\ than\ 100,\ its\ square\ root\ is\ closer\ to\ 9\ than\ 10.\\Hence,\\9\\[/tex]

Or you can directly perform long division to obtain 9.487 as the result. 9.487 is closer to 9 than 10. Hence, 9

[tex]\huge\boxed{y=-\frac{4}{3}}[/tex]

To find the equation for a line in slope-intercept form, we need to find the slope and the y-intercept.

The y-intercept is easy to find. It's just the value of [tex]x[/tex] when [tex]y=0[/tex]. In this case, the y-intercept is [tex]0[/tex] since the line goes through the origin.

To find the slope, we use the slope formula, where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are two known points. In this case, we'll use the only two points we have: [tex](0, 0)[/tex] and [tex](-3, 4)[/tex]

[tex]\begin{aligned}m&=\frac{y_2-y_1}{x_2-x_1}\\&=\frac{4-0}{-3-0}\\&=\frac{4}{-3}\\&=-\frac{4}{3}\end{aligned}[/tex]

Finally, we put it all together in slope-intercept form, where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept.

[tex]y=mx+b\\y=-\dfrac{4}{3}x+0\\\boxed{y=-\frac{4}{3}}[/tex]

[tex]\displaystyle\Huge \bf\red{\underline{\underline{ANSWER}}}

[/tex]

Let the speed of the train be x km/hr and the speed of the bus is y km/hr.

So according to question and using

[tex] \huge \boxed{\sf{Time = \frac{Distance}{speed}}}

[/tex]

Total distance =300 km

Mansi travels 60 km by train and 300−60=240 by bus in 4 minute,

[tex] \bf\frac{60}{x} + \frac{240}{y} = \red4

[/tex]

and 100 km by train, 300−100=200 by bus, and takes 10 minutes more,

[tex] \bf {\frac{100}{x} + \frac{200}{y} = 4 + \frac{1}{6} = \frac{24 + 1 }{6} = \purple{\frac{25}{6}}}

[/tex]

Now, let

[tex]\bf\color{blue}{\frac{1}{x} = a}[/tex]

and.

[tex] \bf \color{blue}{ \frac{1}{y} = b }[/tex]

[tex]\bfthen 60a+240b=4.............(1)[/tex]

[tex]\bf100a+200b=25/6----(2)[/tex]

multiply (1) by 5 and (2) by 6 we get

[tex]\bf300a+1200b=20..........(3)[/tex]

[tex]\bf600a+1200b=25...........(4)[/tex]

Subtracting (3) and (4) we get

[tex]\bf \green{−300a=−5}[/tex]

[tex]\bf{a = \frac{1}{60}}[/tex]

Putting the value of a in (1) we get

[tex]\bf{60 \times \frac{1}{60} + 240b = 4}[/tex]

[tex]

\bf240b = 3 \\ \\ \bf b = \frac{1}{80} [/tex]

Now ,

[tex] \bf\frac{1}{x} = a \\ \\ \bf \red{a = 60 km/h \: \blue \bigstar}[/tex]

[tex] \bf\frac{1}{y} = b \\ \\ \bf \red {b = 80 km/h \: \pink \bigstar} [/tex]

Hence, the speed of the train is 60 km/hr and the speed of the bus is 80 km/hr.

Step-by-step explanation:

Answer:

C. 60

Step-by-step explanation:

48+72=120

x=180-120

x=60

The value of x from the given diagram is 60 degrees

The sum of the interior angle of a triangle is 180 degrees. Since the two lines intersect parallel lines m and n, then;

Taking the sum of angle in the triangle;

m<3 + x + 72 = 180

48 + x + 72 = 180

120 + x = 180

x = 180 - 120

x = 60 degrees

Hence the value of x from the given diagram is 60 degrees

The increment in the model is 106cm

Step-by-step explanation:

Given

[tex]Initial\ Height = 53cm[/tex]

[tex]Final\ Height = 159cm[/tex]

Required

Determine the increment

To do this, we simply subtract the initial height of the building from the final height

[tex]Increment = Final\ Height - Initial\ Height[/tex]

[tex]Increment = 159cm - 53cm[/tex]

[tex]Increment = 106cm[/tex]

Step-by-step explanation:

If Diamond was using addition, then the only number that can be added to 8 in order to get -5 would be -13. This is because 13 is 5 more than 8. Therefore, a negative 13 (-13) added to 8 would mean that you would have to move to the left of the number line 13 places which would cause you to pass 0 by a total of 5 spaces to the left, leaving you at -5

Answer:

X= 5

Step-by-step explanation:

The value of x in the equation 19x - 36 and 6x + 31 are 36 / 19 and -31 / 6 respectively.

A formula known as an equation uses the equals sign to denote the equality of two expressions. Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given:

19x - 36 = 0

6x + 31 = 0

Solve the above equation by using the transformed  as shown below,

19x - 36 = 0

19x = 36

x = 36 / 19

x = 1.895

For the second one, do the same as shown below,

6x + 31 = 0

6x = -31

x = -31 / 6

x = -5.167
