Graph the line for y+1=−3/5(x−4) on the coordinate plane.

Naddika [18.5K]

Please enclose that -3/5 in parentheses: y+1= (−3/5)(x−4)

Let's use the intercept method to graph this line.
First, set x = 0 and find y; this y will be the y-coordinate of the vertical intercept:

y+1= (−3/5)(0−4) => y = -1 + 12/5 = -5/5 + 12/5 = 7/5. Plot (0, 7/5).

Next, set y = 0 and find x; this will give us the coordinate of the horiz. int.:

0+1= (−3/5)(x−4) => -5/3 = x - 4, or x = 4- 5/3, or x = 7/3. Plot (7/3, 0).

Now draw a straight line thru these two points.

In the following figure, the value of x is____

zubka84 [21]

Answer:

x ≈ 8.3 ( to the nearest tenth )

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos41° = $\frac{adjacent}{hypotenuse}$ = $\frac{BC}{AB}$ = $\frac{x}{11}$

Multiply both sides by 11

11 × cos41° = x, thus

x ≈ 8.3

Answer:

the answer is B. 99x + 84 ≥ 1,150

Step-by-step explanation:

the total price of the shirts was 84 dollars

the price of the watches was 99 each which is 99x

and it has to be less than 1150 or equal to that amount otherwise she would go over her savings

If the length of FG is 6 units, what is the length of EH?

QveST [7]

FG goes through the center of the circle, so FG is diameter.

$d = 2r \\ r = \dfrac{d}{2} \\ \\ r = \dfrac{6}{2} = 3$

EH=r=3

Answer: EH=3

I guess I'm lacking in differential equations. I couldn't solve this question. Can you help me?

Sonja [21]

Answer:

See Explanation.

General Formulas and Concepts:

Pre-Algebra

Equality Properties

Reciprocals

Algebra II

Log/Ln Property: $ln(\frac{a}{b} ) = ln(a) - ln(b)$

Calculus

Derivatives

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Chain Rule: $\frac{d}{dx}[f(g(x))] =f'(g(x)) \cdot g'(x)$

Derivative of Ln: $\frac{d}{dx} [ln(u)] = \frac{u'}{u}$

Step-by-step explanation:

Step 1: Define

$ln(\frac{2x-1}{x-1} )=t$

Step 2: Differentiate

Rewrite: $t = ln(\frac{2x-1}{x-1})$
Rewrite [Ln Properties]: $t = ln(2x-1) - ln(x - 1)$
Differentiate [Ln/Chain Rule/Basic Power Rule]: $\frac{dt}{dx} = \frac{1}{2x-1} \cdot 2 - \frac{1}{x-1} \cdot 1$
Simplify: $\frac{dt}{dx} = \frac{2}{2x-1} - \frac{1}{x-1}$
Rewrite: $\frac{dt}{dx} = \frac{2(x-1)}{(2x-1)(x-1)} - \frac{2x-1}{(2x-1)(x-1)}$
Combine: $\frac{dt}{dx} = \frac{-1}{(2x-1)(x-1)}$
Reciprocate: $\frac{dx}{dt} = -(2x-1)(x-1)$
Distribute: $\frac{dx}{dt} = (1-2x)(x-1)$
