36 What is the equation of the line that passes through the point (-2, 7) and has a slope of zero?
jya

Answer:

Step-by-step explanation:

-3x+4y=4

-5x-3y=26

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

-8x+y=30

y=8x+30

Plug 8x+30 back into -5x-3y=26

-5x-3(8x+30)=26

-5x-24x+90=20

-29x=-70

x=2.413

Plug 2.413 into y=8x+30

y=8(2.413)+30

y=19.304+30

y=49.304

Hope I helped :)

Answer:

32mm

Step-by-step explanation:

8*4=32

Answer:

32 mm

Step-by-step explanation:

To find the perimeter of a shape we add up the sides, and in the case of a suare all the sides are the same. So since we are given the side length of one side (8 mm) we jsut add that up 4 times to get the perimeter of 32 mm

Step-by-step explanation:

Answer:

3+(-5)-7+6=3-5-7+6=-3

A straight line is represented by a linear function.

The equation of the line is [tex]y = -\frac 14 x[/tex]

From the coordinate plane, the line passes through the following points

[tex](x,y) =(0,0)\ (4,-1)[/tex]

The slope of the above points is calculated using:

[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

So, the above equation becomes

[tex]m = \frac{-1 - 0}{4-0}[/tex]

This gives

[tex]m = \frac{-1}{4}[/tex]

Rewrite as:

[tex]m = -\frac{1}{4}[/tex]

The line equation is then calculated as:

[tex]y = m(x-x_1) + y_1[/tex]

So, we have:

[tex]y = -\frac 14 (x-0) + 0[/tex]

This gives

[tex]y = -\frac 14 (x)[/tex]

Remove bracket

[tex]y = -\frac 14 x[/tex]

Hence, the equation of the line is [tex]y = -\frac 14 x[/tex]

[tex] \tan (A +B) = - 6\frac{6}{13} [/tex]

Step-by-step explanation:

[tex] \sin \: A = \frac{3}{5}...(given) \\ \\ \because\cos A = \pm \sqrt{1 - { \sin }^{2}\: A } \\ \\ \ \therefore\cos A = \pm \sqrt{1 - \bigg( \frac{3}{5} \bigg) ^{2}} \\ \\ \ \therefore\cos A = \pm \sqrt{1 - \frac{9}{25}} \\ \\ \therefore\cos A = \pm \sqrt{ \frac{25 - 9}{25} } \\ \\ \therefore\cos A = \pm \sqrt{ \frac{16}{25}} \\ \\ \therefore\cos A = \pm { \frac{4}{5}} \\ \\ \because \: \angle A \: is \: in \: quadrant \: I \\ \\ \therefore \: \cos A = { \frac{4}{5}} \\ \\ \tan \: A = \frac{ \sin \: A}{\cos \: A} \\ \\ \tan \: A = \frac{ \frac{3}{5} }{ \frac{4}{5} } \\ \\ \tan \: A = \frac{3}{4} \\ \\ \because \tan (A +B) = \frac{ \tan A + \tan B }{1 - \tan A \tan B } \\ \\ \therefore \tan (A +B) = \frac{ \frac{3}{4} + \frac{15}{8} }{1 - \frac{3}{4} \times \frac{15}{8} } \\ \\ \therefore \tan (A +B) = \frac{ \frac{6}{8} + \frac{15}{8} }{1 - \frac{45}{32}} \\ \\ \therefore \tan (A +B) = \frac{ \frac{21}{8} }{\frac{32 - 45}{32}} \\ \\ \therefore \tan (A +B) = \frac{ \frac{21}{8} }{\frac{ - 13}{32}} \\ \\ \therefore \tan (A +B) = \frac{21}{8} \times \bigg(- \frac{32}{13 } \bigg)\\ \\ \therefore \tan (A +B) = - \frac{84}{13} \\ \\ \therefore \tan (A +B) = - 6\frac{6}{13} [/tex]

Answer:

1.8m²

Step-by-step explanation:

∅= 51× π/180 = 17π/60

area of sector= 1/2 × r²× ∅

= 1/2 × 2²× 17π/60

= 34π/60

= 1.78m²

Answer:

8 miles

Step-by-step explanation:

If we divide 70 by 50, we get the unit rate for the ratio 70 minutes for every 50 miles.

70÷50=1.4

So the runner is running 1.4 minutes per mile. We can multiply this unit rate by the number of miles:

1.4 minutes mile × 5 miles = 7 minutes

Thus it will take her 7 minutes to run 5 miles at this pace.

If it takes her 7 minutes to run 5 miles, it will take her 7÷5 = 1.4 minutes to run 6÷3=2 miles at the same pace.

If it takes her 1.4 minutes to run 5 miles, it will take her 1.4×5=7 minutes to run 4×2=8 miles at the same pace. Since 60 minutes is 1 hour, she is running at a speed of 8 miles per hour.

We found her pace in minutes per miles in part (a).
