Answer:

x= -22

Step-by-step explanation:

3x=5x+44

subtract 2x from both sides and leave only x on one side 3x(-2x)=5x(-2x)+44

then you get

x=3x+44

then you subtract the 3x to both sides

x(-3x)=3x(-3x)+44

then you get

-2x=44

and divide 2 on each side so-

x= -22

Put these in point slope form !!

quester [9]

point slope form formula { (y-y1) = m (x-x1) }

so 1. (y-3) = 1/8 (x-3)

2. ( y- 30 ) = -4 (x-6)

3. ( y -7) = 0.25 (x +8)

4 . ( y -2 ) = 1 ( x-0)

Slope of equation :- The slope-intercept form of a line is a way of writing the equation of a line so that the slope of the line and the y-intercept are easily identifiable. The slope is the steepness of the line, and the y-intercept is the place the line crosses the y-axis.

A cylinder has a helght of 16 cm and a radius of 5 cm. A cone has a helght of 12 cm and a radius of 4 cm. If the cone is placed

erma4kov [3.2K]

Answer:

1055.04 cm³

Step-by-step explanation:

Given that,

Height of a cylinder, h = 16 cm

Radius of the cylinder, r = 5 cm

The height of a cone, h' = 12 cm

The radius of a cone, r' = 4 cm

The volume of the cylinder will be :

$V=\pi r^2 h\\\\=3.14\times 5^2\times 16\\\\=1256\ cm^3$

The volume of a cone is given by :

$V'=\dfrac{1}{3}\pi r^2 h\\\\=\dfrac{1}{3}\times 3.14\times (4)^2\times 12\\\\=200.96\ cm^3$

Volume of the air surrounding the cone Inside the cylinder = 1256 - 200.96 = 1055.04 cm³

Hence, the required answer is equal to 1055.04 cm³.

The table shows the relationship between the average number of hours students studied for a mathematics test and their

lina2011 [118]

Answer:

Step-by-step explanation:

I'm going to ponder a guess that the numbers shown, 0, 62, 1, 78, 2 ,etc. are part of a table. Having said that, the answers, when graphed, create a sort of parabola, meaning that the function itself is non-linear. This exterminates option A and B. Now its just a matter of seeing which way it goes, and since 78 is higher than 62, and 85 is higher than 78, it obviously increases, rather than decreases. This makes D our final answer.

FITH TIME POSTING ILL GIVE BRAINLY

Sindrei [870]

Answer: m∠2 = 160°, m∠3 = 20°.

Step-by-Step Explanation: We know that m∠1 = 160°.

The values of both m∠1 and m∠2 are equivalent, which means that m∠2 is also 160°. The interior angles of a rhombus always add up to 360°, and when we add both 1 & 2, we get 320°.

The other opposite ends of a rhombus's interior measures are also the same in value. ... To figure out what m∠3 is, let's do the following steps:

1. 360-320 = 40

This means that the remaining two angle measurements will add up to 40°.

2. 40/2 = 20.

The final missing angle; m∠3 = 20°.

3. There, done!! Good luck!

P.S. Can I please have Brainly?
