A line has the same slope as the line 3x+9y=5 and passes though the point (-1,2).what is the equation of the line?

MrRissso [65]

Answer:

y = -1/3x + 5/3

Step-by-step explanation:

First solve the equation. Simply put it is y = -1/3x + 5/9.

So, we have our slope which is -1/3. Now just plug it in.

y - y1 = m(x - x1)

y - 2 = -1/3(x - (-1))

Distribute.

y - 2 = -1/3x - 1/3

Add 2 to both sides

you get y=-1/3x + 5/3

5. Find the surface area of the cone. Round to<br> the nearest hundredth.<br> 2 ft<br> 6 ft

den301095 [7]

Answer:

$52.3m^2$

Step-by-step explanation:

Use these formulas

$A=\pi rl+\pi r^2\\l=\sqrt{r^2+h^2}$

Now solve

$A=\pi r(r+\sqrt{h^2+r^2} )\\=\pi *2*(2\sqrt{6^2+2^2} )\\=52.3m^2$

If two triangles are congruent, which of the following statements must be true? Check all that apply.

bonufazy [111]

Answer:

All statements are correct for two congruent triangles

Step-by-step explanation:

If two triangles are congruent than the rules states that

Triangles are congruent when all corresponding sides and interior angles are congruent. The triangles will have the same shape and size, but one may be a mirror image of the other.

As the fig shows two triangle

Δ PQR

Δ LMN

All three corresponding sides of triangle are congruent

all three corresponding angles are congruent

Both triangle are of same size

Both are of same shape

hence all the statements are CORRECT

Find the 12th term of an AP of the form 7, 12, 17, 22

Nostrana [21]

Answer:

Step-by-step explanation:

The rule will be

Ni=(i-1)*5+2

i=1 → N=(1–1)*5+2=0*5+2=0+2=2
i=2 → N=(2–1)*5+2=1*5+2=5+2=7
i=3 → N=(3–1)*5+2=2*5+2=10+2=12
i=4 → N=(4–1)*5+2=3*5+2=15+2=17
i=5 → N=(5–1)*5+2=4*5+2=20+2=22
i=6 → N=(6–1)*5+2=5*5+2=25+2=27
