tigry1 [53]
8.5x + 55 = 123

You would use the formula: mx + b = y

The slope is the amount of money each day(mx),and the y-intercept would be the fee(b) and the total cost would be y.

How can you find the sum of the angle measures in a triangle?
sattari [20]

Answer:

a Euclidean space, the sum of angles of a triangle equals the straight angle (180 degrees, π radians, two right angles, or a half-turn). A triangle has three angles, one at each vertex, bounded by a pair of adjacent sides.

Answer:

The last one

Step-by-step explanation:

The standard method for solving an equation like 3x + 5 = 26 is to use

the Subtraction Property of Equality and then the Division Property of

Equality.

3x + 5 = 26

you would have to subtract first to get your answer

so subtract 5 on both sides

3x= 21

then u would have to divide 3 by both sides to get the x alone/ isolated

x= 7

and that is why u should use " Subtraction Property of Equality and then the Division Property of  Equality, " as your method.

Help 30 points and i will mark brainliest for the best answer which will be more points
klasskru [66]

Answer:

See below

Step-by-step explanation:

From the table we see there is a relation between x and y values

Every step change of x = 0.5, every step change of y = 2

<u>This relation is linear. The formula for linear function is:</u>

  • y = mx + b

<u>Using to pairs of points to get the slope and y-intercept</u>

  • (0, 60) and (1, 64)

<u>Calculating the slope:</u>

  • m = (64 - 60)/(1 - 0) = 4/1 = 4
  • y - intercept is 60 as per point (0, 60)

<u>So the function is</u>

  • y = 4x + 60
<h3>Part A</h3>
  • Yes. Described above
<h3>Part B</h3>
  • y = 4x + 60
<h3>Part C</h3>
  • Slope is the steepness of the line.
  • y -intercept is the lowest score with no time spent studying
