Answer:

Step-by-step explanation:

Alright, lets get started.

The given equation is :

$-2(x+3)=-10$

If we divide the equation with -2 in both sides

$\frac{-2(x+3)}{-2}=\frac{-10}{-2}$

$(x+3)=5$

$x+3=5$

Subtract 3 in both sides

$x+3-3=5-3$

$x=2$

So, the first step of simplifying equation is divide equation with -2. : Answer

Hope it will help :)

<u>Trigonometric Ratios</u>

The ratios of the sides of a right triangle are called trigonometric ratios. There are six trigonometric ratios, sine, cosine, tangent, cosecant, secant, and cotangent.

The longest side of the triangle is called the hypotenuse and the other two sides are the legs.

Selecting any of the acute angles as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides.

Note we are given an angle of 25°. The opposite side is 12 and the adjacent side is x. We need to relate those sides with a trig function (the tangent ratio)

Tangent Ratio:

$\displaystyle \tan\theta=\frac{\text{opposite leg}}{\text{adjacent leg}}$

Substituting:

$\displaystyle \tan 25^\circ=\frac{12}{x}$

Solving for x:

$\displaystyle x=\frac{12}{\tan 25^\circ}$

Calculating:

$\displaystyle x=\frac{12}{0.466307}$

x = 25.734083

Round to 3 decimals:

$\mathbf{x \approx 25.734}$

Using the quotient of powers rule we know that x2 x2 = x2-2 = x0. We also know that x2 x2 = 1 since any number divided by itself

Y=1/3x what is the slope

Karolina [17]

Answer:

Slope = $\frac{1}{3}$

Step-by-step explanation:

The equation for finding slope is:

$y = mx+b$

In the equation, m is the slope, x is the x-intercept, and b is the y-intercept. The number next to x is ALWAYS the slope.

Your equation:

$y = \frac{1}{3} x$

The number(fraction) next to x is $\frac{1}{3}$ . Therefore, your answer will be $\frac{1}{3}$

In a scale drawing of a house, 1 inch=4 1/2 feet. If the length of a kitchen is 2 1/4 inches on a scale drawing, what is the act

ch4aika [34]

Answer:

10.125 feet.

Step-by-step explanation:

you can use the rule of three to answer this question, the data we have is:

inches feet

1 → 4 1/2

2 1/4 → x

tha last table just indicates what the problem tells us, that one inch is equal to 4 1/2 feet and we want to know how much in feet the 2 1/4 inches are.

For this we multiply the cross quantities:

$x=(2\frac{1}{4} )(4\frac{1}{2} )=2.25*4.5=10.125 ft$

the actual length of the kitchen is 10.125 feet.
