Solve for y -5y+8=-3y+10 what is the answer

2 answers:

8 0

-5y + 8 = -3y + 10
We need to get y on one side.
Add 3y to both sides.
-2y + 8 = 10
We need to get 2y by itself.
Subtract 8 from both sides.
-2y = 2
Divide both sides by -2 to solve for y.
y = -1

I hope this helps!

Move like terms to each side and simplify.
$-5y+8=-3y+10 \\ 
-3y+5y=8-10 \\ 2y=-2 \\ y=-1$

Solve

PIT_PIT [208]

A cylinder of radius r cm and height h cm has a curved surface area A cm². Where –

A = 2πrh cm²

a) We are asked to find formula for h.

$\qquad$ $\purple{ \bf \longrightarrow A=2 \pi rh }$

First, overturn the equation

$\qquad$ $\sf \longrightarrow 2 \pi rh =A$

Divide both sides by 2πr

$\qquad$ $\sf \longrightarrow \dfrac{2\pi rh}{2\pi r } = \dfrac{A}{2\pi r}$

$\qquad$ $\sf \longrightarrow \dfrac{\cancel{2 \pi r }h}{\cancel{2\pi r} } = \dfrac{A}{2\pi r}$

$\qquad$ $\purple{\bf \longrightarrow h = \dfrac{A}{2 \pi r }}$

b) Again, we are given –

Curved surface area, A = 93 cm²
Radius, r = 2.5 cm
π = 3.1

$\qquad\qquad\quad\underline{\sf{Substituting \ Values \ :}}$

⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━

$\qquad$ $\bf \longrightarrow h = \dfrac{A}{2\pi r }$

$\qquad$ $\sf \longrightarrow h = \dfrac{93}{2 \times 3.1 \times 2.5 }$

$\qquad$ $\sf \longrightarrow h = \dfrac{93}{15.5}$

$\qquad$ $\sf \longrightarrow h =\cancel{ \dfrac{93}{15.5}}$

$\qquad$ $\pink{ \bf \longrightarrow h = 6\: cm }$

Henceforth, height of the cylinder is 6 cm.

Alecsey [184]

Cirrus clouds form at a height of more than 6000 meters above the earth. This means the inequality should represent the height more than 6000. The correct inequality for this case will be:

$h\ \textgreater \ 6000$

This inequality shows that h which is height where Cirrus clouds are formed is greater than 6000m.

alexira [117]

The exponential function is given by y = 160(1.06)ˣ

<h3>Exponential function</h3>

An exponential function is in the form:

y = abˣ

where a is the initial value of y, b is the multiplier, y, x are variables.

Let y represent the amount of bacteria after x hours.

Given an initial 160 bacteria, hence a = 160.

Also b = 100% + 6% = 106% = 1.06

The exponential function is given by y = 160(1.06)ˣ
