Answer:

Step-by-step explanation:

1). Since angles P and Q are supplementary,

m∠P + m∠Q = 180°

(5x + 3)° + (x + 3)° = 180°

6x + 6 = 180

6x = 174

x = 29

Therefore, Option (3) is the answer.

2). If a point P lies in the interior of ∠RST,

m∠RST = m∠RSP + m∠TPS

(Since, line SP is bisector of angle RST)

m∠RST = 40° + 10°

= 50°

Therefore, option (2) is the answer.

3). AB = distance between two points A and B on a number line

= 8 - (-12)

= 8 + 12

= 20

Therefore, length of AB = 20 units.

Please answer this question thx ❤️ y=x+1 4x + y = 6

N76 [4]

Step-by-step explanation:

Hey there!

Here, The equations are:

y = x+1........(i)

4x + y = 6........(ii).

Now,

Putting equation (i) in (ii)

4x + y = 6

4x + (x + 1) = 6

5x + 1 = 6

5x = 6-1

$x = \frac{5}{5}$

Therefore, x= 1

Putting the value of x in equation (i).

y = x+1

y = 1+1

Therefore the value of y is 2.

Check:

y = x+1

2 = 1+1

2=2 ( True ).

Hope it helps....

Evaluate using suitable identity: c). 98²

Vesnalui [34]

Step-by-step explanation:

<h3>★ Solution :-</h3>

$\sf \longmapsto 98^2$

$\sf \longmapsto (a - b)^2 = a^2 - 2ab + b^2$

Here,

a = 100
b = 2

$\sf \longmapsto (100 - 2)^2 = 100^2 - 2(100)(2) + 2^2$

$\sf \longmapsto 100^2 - 2(100)(2) + 2^2$

$\sf \longmapsto 10000 - 400 + 4$

$\sf \longmapsto 9606$

How do I write the slope (which I found using y2-y1/x2-x2) in Slope Intercept Form (y=mx+b)?

Oliga [24]

In y = mx + b, m is the slope and b is the y-intercept.

So, first substitute the value: your found slope goes in the place of m

Then, find the y-intercept by, in addition to substituting your slope, replace x with the x value of your coordinate and y with the y value of your coordinate in the formula and solve for b

Hope this helps!

An airplane is at 32,000 ft above sea level and descends at an average rate of 1,000 ft per minute. How many minutes will it tak

slavikrds [6]

29 minutes- at a rate of 1,000 feet a minute, it would take 32 minutes to reach sea level (32,000/1000=32)but if you subtract 3000 from 32000 to remain 3000 feet above sea level, you have 29000 feet to descend which will take 29 minutes
