May you plz help me I am struggling with slopes

What is four and half minus two three fourths?

Lady bird [3.3K]

Answer:

$1\frac{3}{4}$

Step-by-step explanation:

$4\frac{1}{2} -2\frac{3}{4}$

The way you want to do this is to make all the numbers into a fraction. You do that by multiplying the whole number by the denominator, or the bottom of the fraction, then adding that to the numerator, or the top of the fraction.

So, $4\frac{1}{2}$ becomes $\frac{9}{2}$ , and $2\frac{3}{4}$ becomes $\frac{11}{4}$ .

Then, you find the least common denominator. The least common denominator (LCD) is the smallest number that can be a common denominator for a set of fractions. In our case, that would be 4, since 2 can multiply into 4.

So, $\frac{9}{2}$ is multiplied by 2, and becomes $\frac{18}{4}$ . $\frac{11}{4}$ stays the same.

And finally, you subtract. When subtracting or adding fractions, you leave the denominator alone, and only work with the top number.

So, $\frac{18}{4}-\frac{11}{4}$ , which equals $\frac{7}{4}$ .

Now, you could technically stop there. However, most teachers ask that you put it back into whole number form. To do that, divide the numerator by the denominator, and whatever remains goes back into the fraction.

So, $\frac{7}{4}=1\frac{3}{4}$

That's your answer! Hope this helps.

Answer:

Approximately 14.65 kilometers.

Step-by-step explanation:

Please refer to the drawing.

So, to find our distance, we essentially just need to find the value of x.

To do so, we can use the Law of Sines.

Note that ∠a corresponds to the 12km, and ∠c corresponds to x.

So, let's find each of the angles first.

Note that from our ending point, the bearing to the lighthouse is 125°.

This means, if you refer to the drawing:

$a+b=90$

This is because they are complementary.

We also know that:

$90+b=125$

From our bearing.

So, let's solve for b. Subtract 90 from both sides:

$b=35$

Substitute this back into our first equation to acquire:

$a+35=90$

Subtract 35 from both sides:

$a=55\textdegree$

Now, we can use the fact that the interior angles of a triangle sum to 180 to find c. We already know that one angle is 36 and the other is 55. So:

$36+55+c=180$

Add:

$91+c=180$

Subtract 91 from both sides:

$c=89\textdegree$

Now, we can use the Law of Sines, which states:

$\frac{\sin(A)}{a}=\frac{\sin(B)}{b}=\frac{\sin(C)}{c}$

It doesn't really matter which ratio we use as long as we align the sides and angles correctly.

Recall that ∠a correspond to 12km while ∠c corresponds to x.

So, let's substitute 12 for a, 55 for A, x for b, and 89 for B. This yields:

$\frac{\sin(55)}{12}=\frac{\sin(89)}{x}$

So, to find the distance traveled, we just have to find x.

Cross-multiply:

$12\sin(89)=x\sin(55)$

Divide both sides by sin(55). This yields:

$x=\frac{12\sin(89)}{\sin(55)}$

Divide. Use a calculator. Make sure you're in Degrees mode. This gives us:

$x\approx14.65$

So, the ship approximately traveled 14.65 kilometers from Point A to Point B.

And we're done!

Based on information in the table, which equation can be used to model the relationship between x and y?.

Ivahew [28]

The relationship between y and x is y = 5x + 15.

<h3>Linear equation</h3>

A linear equation is in the form:

y = mx + b

where y, x are the variables, m is the rate of change (slope) and b is the initial value of y (y intercept).

From the table, using point (5, 40) and (25, 140):

$y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-40=\frac{140-40}{25-5} (x-5)\\\\y=5x+15$

The relationship between y and x is y = 5x + 15.
