IM LITERALLY BEGGIIINNGG HURRRYYYY PLSSSS HELP MEH
Dmitrij [34]

x is 53

angle PQD is equal to APQ. so its 62 degrees

PRC and PRD are supplement so their sum is 180.

PRD=115 PRC= 180 -115= 65

the sum of the angles of a triangle is equal to 180. so:

x = 180 - (62 + 65) = 53

good luck

Find the equation of the line that passes through (1,3) and is perpendicular to y = 1 − 2 x
egoroff_w [7]

Answer:

y=\displaystyle\frac{1}{2} x+\displaystyle \frac{5}{2}

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: y=mx+b where <em>m</em> is the slope and <em>b</em> is the y-intercept.

Perpendicular lines always have slopes that are negative reciprocals (ex. 1/2 and -2, 3/4 and -4/3)

<u>Determine the slope (</u><em><u>m</u></em><u>):</u>

y = 1 -2x

Rearrange into slope-intercept form:

y = -2x+1

Now, we can identify clearly that the slope is -2. Because perpendicular lines always have slopes that are negative reciprocals, a perpendicular line would have a slope of \displaystyle\frac{1}{2}. Plug this into y=mx+b:

y=\displaystyle\frac{1}{2} x+b

<u>Determine the y-intercept (</u><em><u>b</u></em><u>):</u>

y=\displaystyle\frac{1}{2} x+b

Plug in the given point (1,3) and solve for <em>b</em>:

3=\displaystyle\frac{1}{2} *1+b\\\\b=\displaystyle \frac{5}{2}

Therefore, the y-intercept is \displaystyle \frac{5}{2}. Plug this back into y=\displaystyle\frac{1}{2} x+b:

y=\displaystyle\frac{1}{2} x+\displaystyle \frac{5}{2}

I hope this helps!

Answer:

Step-by-step explanation: mass of sheep=6 x 10 kg

                                             mass of ant= 3 x 10 kg

=6 x 10=60, 3 x 10=30

60/30=20

therefore in standard form

20=2 x 10

ans: 2 x 10 kg

The sheep weighs 2x10kg more than the ant.
