I don't know the answer but I am sure you could go on Khan Academy to find the answer and a tutorial fully explaining how to solve it in the future.

function a and function b are linear functions. function a is represented by the table values. function b is represented by the
Kryger [21]

The y-intercept of B is greater than the y-intercept of A and the rate of change of function A is less than the rate of change of B

<h3>Linear functions </h3>

The standard linear equation is expressed as y = mx + b

For the given table;

The y-intercept occur at x = 0

y = 3x + 4

y = 3(0) + 4

y = 4

For the table;

Using the coordinate points (1, 2) and (3,10)

rate of change "m" = 10-2/3-1
m = 8/2

m = 4

Recall that y = mx + b

2 = 4(1) + b

b = -2

Hence the y-intercept of B is greater than the y-intercept of A and the rate of change of function A is less than the rate of change of B.

The measure of an angle is 4y. Find the measure of its complement.
Serjik [45]
Complementary angles are angles whose measure add up to 90°.

So, if one angle is 4y, the complementary angle is 90°- 4y. Choice A.

Complementary angles does not necessarily need to share a line or vertex. As long as both angles have a sum of 90°, then, they are complementary angles.

Angles who has a sum of 180° are called supplementary angles.

Someome help with this plz?​
USPshnik [31]

Answer:

cosec <W = 68/60

Step-by-step explanation:

Using SOH CAH TOA identity

sin theta = opposite/hypotenuse

sin<W = XV/WV

Get WV using pythagoras theorem

WV² = 32²+60²

WV² = 1024 + 3600

WV² = 4624

WV = 68

sin<W =60/68

Since cosec <W = 1/sin<W

cosec <W = 68/60
