What is the slope and y-intercept -4x+2y=-2

Mathematics
1 answer:
natka813 [3]2 years ago
8 0

Answer:

Slope: 2

Y-intercept:  (0, -1) or - 1

Step-by-step explanation:

Given the linear equation, -4x + 2y = -2:

Transform the given equation into its slope-intercept form, y = mx + b:

-4x + 2y = -2

Add 4x to both sides:

-4x + 4x + 2y = 4x - 2

2y = 4x - 2

Divide both sides by 2 to isolate y:

\frac{2y}{2} = \frac{4x - 2}{2}

y = 2x - 1 ⇒ This is the slope-intercept form where the slope, m = 2, and the y-intercept is (0, -1).

Prove the following limit. lim x → 5 3x − 8 = 7 SOLUTION 1. Preliminary analysis of the problem (guessing a value for δ). Let ε
Temka [501]

\displaystyle\lim_{x\to5}3x-8=7

means to say that for any given \varepsilon>0, we can find \delta such that anytime |x-5| (i.e. the whenever x is "close enough" to 5), we can guarantee that |(3x-8)-7| (i.e. the value of 3x-8 is "close enough" to the limit value).

What we want to end up with is

|(3x-8)-7|=|3x-15|=3|x-5|

Dividing both sides by 3 gives

|x-5|

which suggests \delta=\dfrac\varepsilon3 is a sufficient threshold.

The proof itself is essentially the reverse of this analysis: Let \varepsilon>0 be given. Then if

|x-5|

and so the limit is 7. QED

Find the total surface area of the cone in the figure. ( use rr=3.14.)
nikitadnepr [17]

Answer:

Answer D

Step-by-step explanation:

The formula is A = pi r(r+\sqrt{h^2+r^2}). We have our r (radius) and h (height), so plugging it all in would give us A = (3.14)(5 + sqrt(12^2)+(5^2). After computing this, you would get answer D, 282.6.

What solid 3D object is produced by rotating the triangle about line m?
elena55 [62]

Answer: A cone with height 3 and radius 1

Step-by-step explanation:

Hi, searching I found the image for the question, attached down below.

By rotating the triangle about line m, a cone with height 3 and radius 1 is produced.

Solid 3d objects are produced by rotating a 2d figure around a straight line that lies in the same place.

in our case, if we rotate the triangle around the line, the vertices in touch with the line m remains stationary, while the  remaining vertex follows the path of a circle, creating a cone.

jolli1 [7]

Answer:

beam, vault, uneven bars, floor

Step-by-step explanation:

<u><em>The complete question is</em></u>

A group of gymnasts were asked to name their favorite piece of equipment. 0.33 of the gymnasts chose the vault, 4/9 chose the beam, 0.08 chose the floor exercise, and 1/7 chose the uneven parallel bars. List their choices in order of preference from greatest to least.

step 1

Convert 4/9 and 1/7 to decimals in order to compare with the other values

4/9=0.44

1/7=0.14

step 2

Compare the values

0.44 > 0.33 > 0.14 > 0.08

therefore

The order of preferences from greatest to least is

beam, vault, uneven bars, floor
