Answer:

-82.8

Step-by-step explanation:

15.45 + ( − 98.25)

15.45 - 98.25

= -82.8

Since the two terms are of opposite signs, you have to subtract and use the sign of the greater term (positive or negative)

<u>Answer:</u>

$y = -\frac{2}{3}x + 490$

gradient = = $-\frac{2}{3}$

y-intercept = $490$

<u>Step-by-step explanation:</u>

• The slope-intercept form of an equation takes the general form:

$\boxed{y = mx + c}$ ,

where:

m = slope,

c = y-intercept.

• We are given the equation:

$2x + 3y = 1470$

To change this into the slope-intercept form, we must make y the subject:

$3y = -2x + 1470$ [subtract $2x$ from both sides]

⇒ $y = -\frac{2}{3}x + \frac{1479}{3}$ [divide both sides by 3]

⇒ $y = -\frac{2}{3}x + 490$

• Comparing this equation with the general form equation, we see that:

m = $-\frac{2}{3}$

c = $490$ .

This means that the gradient is $\bf -\frac{2}{3}$ , and the y-intercept is $\bf 490$ .

Is it possible to draw a triangle with numbers 5,6,11

Tatiana [17]

Answer:

Step-by-step explanation:

Let's use the Pythagorean Theorem. For those of you that don't know, it is $a^2 + b^2 = c^2\\$ .

11 is the bigger side in this case, so our formula would go like this: $5^2 + 6^2 = 11^2\\$ .

We now calculate to see if this is true.

25 + 36 $\neq$ 121

Therefore, the answer is wrong.

If (5^2)p = 5^12, what is the value of p?

mr Goodwill [35]

Divide both sides by 5^2 (which is 25). So p = (5^12)/25. I can't be bothered to plug in into a calculator but be my guest.
