Answer: C, In Step 2 the expression for y should be subsituted in the other equation.
Answer:
C. -1
Step-by-step explanation:
Find the y intercept by plugging in the slope and a given point into the equation y = mx + b. Then, solve for b:
y = mx + b
-7 = -3(2) + b
-7 = -6 + b
-1 = b
So, the y intercept is -1.
The correct answer is C. -1
Answer:
A. right 2, up 3
Step-by-step explanation:
We have that,
The function 
is transformed to 
.
We see that,
The function f(x) is translated 2 units to the right and 3 units upwards to obtain the function g(x).
So, the correct transformation is 'right 2, up 3'.
Hence, option A is correct.
Answer:
Step-by-step explanation:
The nickels in the envelope is $0. 12
<h3>How to determine the number</h3>
From the information given, we have that;
Dimes + nickels = $1. 20
1/4 dimes + dimes = $ 1. 35
Let dimes = d
Nickels = n
d + n = 1. 20 equation a
d/4 + d = 1. 35 equation b
Make 'd' subject from equation a
d = 1. 20 - n
Substitute into equation b
1. 20 - n/ 4 + 1. 20 - n = 1. 35
0. 3 - 0. 25n + 1. 20 - n = 1. 35
collect like terms
- 1. 25n = 1. 35 - 1. 5
- 1. 25 = - 0. 15
n = -0. 15/ -1. 25
n = 0. 12
Thus, the number of nickels in the envelope is $0. 12
