Answer:
x= -19
y= -14
Step-by-step explanation:
Substitution.
It tells you what y is already. You substitute that into the second equation and then solve. Then you use that answer and substitute it back into the first equation's x, and then you'll get your full answer.

Answer: 1/4 chance of picking a diamond
Step-by-step explanation:
13 spades + 13 hearts + 13 diamonds + 13 clubs = 52 total
so 13/52 or 1/4
First make an inequality to solve for x
(x + 45) + [(x + 45) - 30] + [2x + (x + 45)] = 180
x = 15
now plug x back into each equation and solve
first angle = 60°
second angle = 30°
third angle = 90°
The function F(t) = 34000(.98)^t, since b = 0.98 < 1, hence the function is decaying and the initial value of the expression is 34,000.
<h3>Exponential equation</h3>
The inverse of exponential equation is logarithmic equation. The standard exponential equation is expressed as;
y = ab^x
where
a is the initial value
b determine the growth rate or decay.
If the value if b < 1, then it is a decay otherwise it is growth.
Given the function F(t) = 34000(.98)^t, since b = 0.98 < 1, hence the function is decaying and the initial value of the expression is 34,000.
