Answer: The number is 9

Step-by-step explanation:

So first we assign a variable the "number" is x.

So 2x-3=15

Then we solve,

2x-3 =15

   +3   +3

2x= 18

2/2x= 18/2

x = 9

The answer is 9
2x-3=15
add 3 to both sides
2x=18
divide both by 2
x=9

To convert a temperature from degrees Celsius to degrees Fahrenheit, you can use the formula F= (C*1.8) + 32 where F is degrees
asambeis [7]

Answer:

The temperature is 50^{\circ}F

Step-by-step explanation:

Given

F= (C*1.8) + 32

Required

Find F when C = 10

F= (C*1.8) + 32

Substitute 10 for C

F = 10 * 1.8 + 32

F = 18 + 32

F = 50

Mhanifa can you please help me on this? I will mark brainliest!
denpristay [2]

Answer:

  • y = -4x + 7

Step-by-step explanation:

<u>Given points:</u>

  • A(-2, -2) and B(6, 0)

The perpendicular bisector passes through the midpoint.

<u>Finding the coordinates of the midpoint first:</u>

  • x = (-2 + 6)/2 = 2, y = (-2 + 0)/2 = -1

<u>Next finding the slope of AB:</u>

  • m = (0 - (-2))/(6 - (-2)) = 2/8 = 1/4

The perpendicular lines have negative-reciprocal slopes.

<u>The line will have a slope of -4 and pass through the point (2, -1)</u>

  • y  - (-1) = -4(x - 2)
  • y + 1 = -4(x - 2)         - point-slope form
  • y = -4x + 7                - slope-intercept form
