Answer:

y=50+15x

Step-by-step explanation:

She already has 50 in her bank so you add that to the equation. The 15x is her $15 deposit times (x) weeks.

Answer:

y=-15x+50

Step-by-step explanation:

You originally had 50 dollars, so +50. Then, it decreases at a rate of 15 every week, so -15x.

Y is the total number of money she has.

y= -15x+50

I have to find the slope for 4. ASAP please help

Lorico [155]

Given:

The objective is to find the slope of the straight line.

Explanation:

The general equation to find the slope is,

$m=\frac{y_2-y_1}{x_2-x_1}$

Let's consider two coordinates from the graph.

$\begin{gathered} (x_1,y_1)=(0,0) \\ (x_2,y_2)=(-1,5) \end{gathered}$

On plugging the values in the equation of slope,

$\begin{gathered} m=\frac{5-0}{-1-0} \\ m=-5 \end{gathered}$

Hence, the slope of the straight line is -5.

Those 2 questions I need help with . find sec θ and tanθ

Zielflug [23.3K]

STEP - BY - STEP EXPLANATION

What to find?

The the value of secθ.

Given:

(4, 3)

⇒(x, y) = (4, 3)

Step 1

Draw a sketch.

Step 2

Substitute the values into the trig. ratio formula below.

$tan\theta=\frac{opposite}{adjacent}$

From the sketch above, opposite = 3 and adjacent = 4

$tan\theta=\frac{3}{4}$

Step 3

Find the value of the hypotenuse side using Pythagoras theorem.

let h be the hypotenuse side.

$\begin{gathered} h^2=4^2+3^2 \\ \\ =16+9 \\ \\ =25 \\ \\ h=5 \end{gathered}$

Hence, hypotenuse = 5

Step 4

Substitute the values into the formula below:

$\begin{gathered} cos\theta=\frac{adjacent}{hypotenuse} \\ \\ =\frac{4}{5} \end{gathered}$

But,

$sec\theta=\frac{1}{cos\theta}=\frac{1}{\frac{4}{5}}=\frac{5}{4}$

ANSWER

secθ= 5/4

tanθ=3/4

miss Akunina [59]

Answer:

$\frac{-13}{60}$

Step-by-step explanation:

So lets get the denominators the same:

$\frac{-4}{5} +\frac{7}{12}$

= $\frac{-48}{60} +\frac{35}{60}$

= $\frac{-13}{60}$

Hoped I helped, have a nice day!
