Answer:

y - 4 = -2(x - 5)

Step-by-step explanation:

point slope form is  y-y1 = m(x-x1)

the original equation is given in slope intercept form y = mx + b

Parallel lines have equal slopes so from the given equation  y = -2x-3

the slope m = -2.

Use the given point (5,4) as (x1, y1).

y - 4 = -2(x - 5)

Answer:

\displaystyle y - 4 = -2(x - 5)

Step-by-step explanation:

Parallel equations have SIMILAR <em>RATE OF CHANGES</em> [<em>SLOPES</em>], so −2 remains as is as you proceed with plugging the information into the Point-Slope Formula:

\displaystyle [5, 4] \\ \\ \boxed{y - 4 = -2(x - 5)}

**Remember, all negative symbols give you the OPPOCITE TERMS OF WHAT THEY <em>REALLY</em> ARE, so make sure both operation symbols are correct.

I am joyous to assist you at any time.

I need help working this algebra 2 question 3/4 - 5/6R = 7/10
Brilliant_brown [7]

Answer:

R = 3/50

Step-by-step explanation:

If you are trying to solve for a variable,

1. Simplify both sides of the equation:

3/4 - 5/6R = 7/10 will now be (-5/6r) + 3/4 = 7/10

2. Add  -3/4 from both sides of the equation:

(-3/4) + 3/4 = 0 and (-3/4) - 7/10 = -1/20.

You will be left with: -5/6r = -1/20.

3. Divide both sides by (-5/6).

(-5/6r) / -5/6 = 1R or just R. (-1/20) / -5/6 = 3/50

You are left with the answer:

R = 3/50

the proper angle for a ladder is about 75 degrees. from the ground. suppose you have a 9 foot ladder. how far from the house sho
icang [17]

ANSWER:

2.33 foot

STEP-BY-STEP EXPLANATION:

We can calculate the distance from the staircase to the wall, by means of the trigonometric cosine ratio, which is the following:

\begin{gathered} \cos \theta=\frac{\text{ adjacent}}{\text{ hypotenuse}} \\ \theta=75\text{\degree} \\ \text{ hypotenuse = 9 foot} \\ \text{adjacent = x} \end{gathered}

Replacing and solving for x:

\begin{gathered} \cos 75=\frac{x}{9} \\ x=9\cdot\cos 75 \\ x=2.33 \end{gathered}

The distance would be 2.33 foot

tigry1 [53]
Let x = liters 20% solution to be added
then

.12(12) + .20x = .14(12+x)
.12(12) + .20x = .14(12+x)
1.44 + .20x = 1.68 + .14x
.20x = .24 + .14x
.06x = .24
x = 4 liters

Defining congruent triangles
seropon [69]

Answer:

E -->R

D-->K

O-->O

Step-by-step explanation:

Assuming you are asking for congruent parts, correspondence is the part which corresponds and is also equal.

Here Angle E corresponds and is congruent to Angle R in these congruent triangles.

Angle D is congruent and corresponds to Angle K for these congruent triangles.

Angle O is equal to Angle O as they are vertical angles across a vertex.
