Please Help! I'm on a Timer!

Answer:

$-0.2(x - 4) = - 1.7$

$-0.2x + 0.8 = - 1.7$

$-0.2x = - 2.5$

$x = 12.5$

Step-by-step explanation:

Solving $-0.2(x - 4) = - 1.7$ using the distributive property:

$(-0.2)(x) + (-0.2)(-4) = - 1.7$

$-0.2x + 0.8 = - 1.7$

Subtract 0.8 from both sides

$-0.2x + 0.8 - 0.8 = - 1.7 - 0.8$

$-0.2x = - 2.5$

Divide both sides by -0.2

$\frac{-0.2x}{-0.2} = \frac{-2.5}{-0.2}$

$x = 12.5$

PLEASE SOMEONE HELP ME ANSWER THIS !!!!

Step-by-step explanation:

Part A: Linear Equation.

One of the points is (0,15). This means 0,15 is the y intercept so b=15.

We can find the slope

$\frac{5 - 15}{1 - 0 } = \frac{ - 10}{1} = - 10$

So our equation is

$y = - 10x + 15$

Part B: Exponential Equation

We know that

$15 = a \times b {}^{0}$

B to the zero power is 1 so

$15 = a$

This means a =15. Now let find b.

$5 = 15 \times b {}^{1}$

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

So the equation is

$y = 15( \frac{1}{3} ) {}^{x}$

Please help! : What is the actual length of a window that is 1 1/4 inches long on a drawing with a scale of 1 inch= 6 feet? This

$\bf \begin{array}{ccllll}
model&actual\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
1&6\\
1\frac{1}{4}&x
\end{array}\implies \cfrac{1}{1\frac{1}{4}}=\cfrac{6}{x}
\\\\\\
1\frac{1}{4}\implies \cfrac{1\cdot 4+1}{4}\implies \cfrac{5}{4}\qquad thus
\\\\\\
$

$\bf \cfrac{1}{\frac{5}{4}}=\cfrac{6}{x}\implies \cfrac{\frac{1}{1}}{\frac{5}{4}}=\cfrac{6}{x}\implies \cfrac{1}{1}\cdot \cfrac{4}{5}=\cfrac{6}{x}\implies \cfrac{4}{5}=\cfrac{6}{x}
\\\\\\
x=\cfrac{5\cdot 6}{4}$
