Check the picture.
The figure shows lines m, n and the line through points A And B, call it

.
1. The angles ABC and CBP are "supplementary" angles, that is angles whose sum is 180°, because together they form one straight angle.
thus,
(2x+5°)+(7x-14°)=180°
9x-9°=180°
9x=189°
x=189°/9=21°.
2. Remark, m and n are parallel, otherwise we can say nothing about the measure of angle P
check the second picture, notice the F shape formed by CBP and P.
Angles CBP and P are called "angles F" or "corresponding angles".
Corresponding angles formed by a line cutting 2 parallel lines, are always congruent (that is equal) so:
m(P)=m(CBP)=7x-14°=7.21°-14°=147°-14°=133°
Answer: 133°
The expression that can be used to represent the list price of the smartphone is 5179.99 * (1- 25%) and the value is 3884.9925
<h3>What expression can be used to represent the list price of the smartphone? </h3>
The given parameters are:
Discount = 25%
Sales price = 5179.99
The expression that can be used to represent the list price of the smartphone is
Expression = Sales price * (1- discount)
So, we have:
Expression = 5179.99 * (1- 25%)
Evaluate
Expression = 3884.9925
Hence, the expression that can be used to represent the list price of the smartphone is 5179.99 * (1- 25%) and the value is 3884.9925

Answer:
a <= 3
Step-by-step explanation:
Answer:
y = -3(x+2)^2 - 6
Step-by-step explanation:
y = a(x+2)^2 -6
-18 = a(-2)^2 - 6
-12 = 4a
a = -3
y = -3(x+2)^2 - 6
In simplify the expression =
1.56 • 10^52 + 3.5 • 10^48
