Y=3x + 4<br>What is the slope?​
slega [8]

Answer:

3

Step-by-step explanation:

In a slope intercept linear equation, the slope is always the number in front of the x value in an equation like y = mx + b.

So the slope is the 3 in front of the x value.

Determine the equation of the line that is parallel to y=23x+4 and passes through the point (3,7).
Licemer1 [7]

Answer:  y = 23x - 62

<u>Step-by-step explanation:</u>

Parallel lines have the same slope.

y = 23x + 4

  m=23   b=4

Input x = 3, y = 7, & m = 23 into the Point-Slope formula to find the equation or the Slope-Intercept formula to find b (you already have m).  I will choose the latter.

 y = mx + b

 7 = 23(3) + b

 7 = 69 + b

-62 = b

m = 23, b = -62  -->  y = 23x - 62

What would z and x equal i need help plz
KATRIN_1 [288]

Answer:

Angle Z =79°        and x = 31.33

Step-by-step explanation:

From the shown parallel and intersecting lines , it is found that,

∠z° = 79°      interior angle on same side of transversal

and ∠z = (6x - 109°)                   corresponding angles

i.e 79°+109°=  6x

or, 188 = 6x

i,e x = 31.33

Hence angle z =79°   , and x  = 31.33

A cylinder has a height of 16 cm and a radius of 5 cm. A cone has a height of 12 cm and a radius of 4 cm. If the cone is placed
Zepler [3.9K]

The volume of the air space surrounding the cone inside the cylinder is 1055.04 cm³

<h3 />

<h3>How to find volume?</h3>

The volume of the air space surrounding the cone inside the cylinder is as follows:

volume of the air space = volume of cylinder - volume of a cone

volume of cylinder = πr²h

volume of cylinder = π16 × 5²

volume of cylinder = 400π

volume of the cone = 1 / 3 πr²h

volume of the cone = 1 / 3 × π × 12 × 4²

volume of the cone = 64π

Therefore,

volume of the air space = 400π - 64π

volume of the air space = 336π

volume of the air space = 1055.04 cm³
