Answer:

95/21

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(2-97)/(-11-10)

m=-95/-21

Fill in the blank to complete the following sentence. The two roots a +sqrt b and a- sqrt b are called ______ radicals.

katrin [286]

The two roots a + sqrt b and a - sqrt b are called conjugate radicals.

Solution:

Given that the two roots a + sqrt b and a - sqrt b are called ______ radicals.

Now let us write the each of the given two radicals in mathematical form.

So, first radical ⇒ a + sqrt b ⇒ $a+\sqrt{b}$ [ since sqrt means square root]

Now second radical ⇒ a - sqrt b ⇒ $a-\sqrt{b}$

We have to find the relation between $a+\sqrt{b} \text { and } a-\sqrt{b}$

Now, if observe $a+\sqrt{b}$ is conjugate of $a-\sqrt{b} \text { as }(a+\sqrt{b})(a-\sqrt{b})=a^{2}-b$

[ where radical is eliminated]

Hence, the two roots a +sqrt b and a- sqrt b are called conjugate radicals

$\underline \mathcal \pink{ GIVEN}$

Base = 2 9/10 km
Height = 4 6/7 km

$\underline \mathcal \purple{ TO \: FIND}$

Area of the triangle

$\underline \mathcal \blue{CALCULATION}$

$\qquad \tt \leadsto \: area = \frac{1}{2} \times base \times height$

$\qquad \bf \nrightarrow \: area = \frac{1}{ \cancel2} \times \cancel2 \frac{9}{10} \times 4 \frac{6}{7}$

$\qquad \bf \nrightarrow \: area = \frac{9}{ \cancel{10}} \times \cancel4 \frac{6}{7}$

$\qquad \bf \nrightarrow \: area = \frac{9}{ 5} \times 2 \frac{6}{7}$

$\qquad \bf \nrightarrow \: area = \frac{108}{ 35} \approx3.08 \: {km}^{2}$

Thus, The area of the triangle is 3.08 kilometers...~

LOOK AT CHART BEFORE THE BULLET PART:

tresset_1 [31]

Answer:

m = -3/4
y-intercept = 399
slope-intercept equation: y = -3/4x + 399

Step-by-step explanation:

It can be easiest simply to solve the equation for y.

3x + 4y = 1596

4y = -3x + 1596 . . . . subtract 3x

y = -3/4x + 399 . . . . divide by 4

From this equation in slope-intercept form you can read the slope as -3/4 and the y-intercept as 399. You already know the equation.
