Answer:

x + y = 84

x^2 = 6 + y

Step-by-step explanation:

Given

x = First Number

y = Second Number

Required

Write a system of equations

<u>Sum is 84</u>

This is represented as:

x + y = 84

<u>Square of first is 6 more than the second</u>

This is represented as:

x^2 = 6 + y

Hence, the equations are:

x + y = 84

x^2 = 6 + y

What is an equation of the line that is parallel to y=4x−10 and passes through (1, 13) ?
klasskru [66]
If a line is parallel to another line,Then the gradients are the same.So m=4 .Using general formula for str8 line, y=mx+c
y = 4x + c
sub in coorfinates (1,13)
13  = 4 + c
So C=9.
y = 4x + 9

Answer:

3. 17x + 5 = 90° ( alternate exterior angles are equal)

=> 17x + = 90 – 5

=> 17x = 85

=> x = 85/17

=> x = 5

4. 63° + c + 110° + 75° + 50° = 360 °

=> c + 298° = 360°

=> c = 360° – 298°

=> c = 62 °

ira [324]

Answer:

Properties of Real Numbers ...

Step-by-step explanation:

Commutative Property of Multiplication (Numbers) 2 • 10 = 10 • 2

Associative Property of Addition (Numbers) 5 + (6 + 7) = (5 + 6) + 7

Associative Property of Multiplication (Numbers) 6 • (3 • 2) = (6 • 3) • 2

Additive Identity (Numbers) 6 + 0 = 6

A cup of coffee which is initially at a temperature of 154∘F is placed in a room which is at a constant temperature of 71∘F. In
Lesechka [4]
Newton's law of cooling is
k (t₁ - t₂) = -ln (T₁ - T∞ / T₂ - T<span>∞)

Use the two data points in the given to find k.

t = 0, T = 154
t = 10, T = 133

Solution:

k(0 - 10) = - ln (154 - 71/ 133 - 71)
-10k = -0.291716
k = 0.02917 or 0.0292

So now find t when T = 100
0.2917 * ( 0 - t) = -ln (154 - 71 / 100 -71)
- 0.02917t = - 1.0515
t = 36. 05 minutes
to the nearest minute t = 36</span>
