What equation is graphed in this figure?

aniked [119]

Based on the graph, the slope is -3, and the y-intercept is 1. So your equation should be:

y = -3x + 1

The answer is C

y + 2 = -3(x - 1)

y + 2 = -3x + 3

y = -3x + 1

Pls help me with this

Free_Kalibri [48]

Answer:

$\boxed{\sf \frac{15}{22} }$

Step-by-step explanation:

The radius of the circle is 7 cm.

The two legs of the triangles are 7cm as well.

Area of a trinagle is ( base × height )/2.

$\frac{7 \times 7}{2} =24.5$

Multiply the value by 2 since there are two triangles.

$24.5 \times 2 = 49$

Calculate the area of the circle.

$\pi r^2$

The radius is given.

$\pi (7)^2$

Take $\pi$ as $\frac{22}{7}$

$49(\frac{22}{7} )$

$=154$

Subtract the area of the two triangles from the area of the whole circle.

$154-49=105$

The area of the shaded part is 105 cm². The total area of the shape is 154cm².

$\frac{105}{154} =\frac{15}{22}$

Illustrate the distributive property to solve 144/8

AURORKA [14]

Answer:

8 (19) or 8 (18 +1)

Step-by-step explanation:

Distributive property means to distribute.

HCF of 144 and 8.

=> 8 is the HCF of 144 and 8

8 (18 + 1)

=> 8 (19)

I have been stuck on this forever plz help <br> What is the surface area of this cylinder

Andrei [34K]

Answer:

1865.16 m^2

Step-by-step explanation:

first let 's find radius of a circle

radius=diameter/2

=18/2

=9 m

area of a cylinder=2πrh+2πr2

=2*3.14*9*24 + 2*3.14*(9)^2

=1356.48 + 2*3.14*81

=1356.48 + 508.68

=1865.16 m^2

• What is the solution to 5x+ 20 = 7(x+2)?

o-na [289]

For this case we must find the solution of the following equation:

$5x + 20 = 7 (x + 2)$

Applying distributive property on the right side of the equation we have:

$5x + 20 = 7x + 14$

Subtracting 7x from both sides of the equation:

$5x-7x + 20 = 14\\-2x + 20 = 14$

Subtracting 20 from both sides of the equation:

$-2x = 14-20$

Different signs are subtracted and the major sign is placed.

$-2x = -6$

Dividing between -2 on both sides of the equation:

$x = \frac {-6} {- 2}\\x = 3$

Thus, the solution of the equation is $x = 3$

Answer:

$x = 3$
