$\\ \bull\longmapsto 4x-1=3y+5$

$\\ \bull\longmapsto 4x-3y=6$

X. intercept

$\\ \bull\longmapsto 4x=6+3y\implies x=\dfrac{3y+6}{4}$

Now

Put 0 on y

$\\ \bull\longmapsto x=\dfrac{3(0)+6}{4}=\dfrac{6}{4}=\dfrac{3}{2}$

Hence

$\\ \bull\longmapsto x-intercept=\left(\dfrac{3}{2},0\right)$

Y intercept:-

$\\ \bull\longmapsto 3y=4x-6\implies y=\dfrac{4x-6}{3}$

Put 0 on x

$\\ \bull\longmapsto y=\dfrac{4(0)-6}{3}=\dfrac{-6}{3}=-2$

Hence.

$\\ \bull\longmapsto y-intercept=(0,-2)$

Is x = -4 a valid solution this linear equation?

HACTEHA [7]

Answer:

Yes, -4 is valid.

Step-by-step explanation:

Lets Find out.

So, using substitution:

$2(-4)+9(-4-1)=8(2(-4)+2)-5\\-8-45=8(-6)-5\\-53=-48-5\\-53=-53$

Yes, -4 is a valid solution.

Hope This Helps!

Consider all angles whose reference angle is 45° with terminal sides not in Quadrant I.The angles that share the same cosine val

Oksana_A [137]

Solution:

As we know reference angle is smallest angle between terminal side and X axis.

As cosine 45 ° is always positive in first and fourth quadrant.

i.e CosФ, Cos (-Ф) or Cos(2π - Ф) have same value.

As, Cos 45°, Cos (-45°) or Cos ( 360° - 45°)= Cos 315°are same.

So, Angles that share the same Cosine value as Cos 45° have same terminal sides will be in Quadrant IV having value Either Cos (-45°) or Cos (315°).

Also, Cos 45° = Sin 45° or Sin 135° i.e terminal side in first Quadrant or second Quadrant.

Juan reads 300 pages 5 days which reading rate is equivalent

katrin [286]

60 pages per day!

It is shown that One is reading 300 pages in five days so we need to find a reading rate which would be the total number of pages one reads over the number of days so the substitute does values by doing 300/5 you would get 60 pages per day
