Answer:
1. C
2. A
Step-by-step explanation:
Step 1: Write equation
3x - 1 = 7
3x = 8
Step 2: Use 1st equation and solve
3x = 8
x = 8/3
Step 3: Use 2nd equation and solve
3x = 8
x = 8/3
Both equations have equivalent solutions and the 2nd equation is the simplified version of the 1st.
Scientists were monitoring the temperature of a solution. It began at 63°F, and the temperature changed by 8°F over the course of 6 hours.
The final temperature of the solution was a minimum of __°f and a maximum of __°f
Answer:55&71
Step-by-step explanation: The 6 hours is unnecessary info. 63-8=55 and 63+8=71.
The final temperature have the minimum should be 55 and the maximum should be 71.
Calculation of the minimum & maximum:Since It began at 63°F, and the temperature changed by 8°F over the course of 6 hours.
So here the minimum should be
= 63-8
= 55
And, the maximum should be
= 63 + 8
= 71

Find the slope of 10y = 7x + 5.
Round to the third.
Answer:
0.7
Step-by-step explanation:
10y = 7x + 5
Divide both sides by 10.
y = 7x/10 + 5/10
y = 0.7x + 0.5
On a straight line of the form y = kx + m, k is the slope of the line.
In our line, y = 0.7x + 0.5, k is 0.7. Thus, the slope of our function is 0.7
Answer: 0.7

O 1) -6
2) -3
3) 3
4) 6
Answer:
f(-2) = - 8Step-by-step explanation:
f(x) = 3x - 2
In order to find f(-2) , substitute the value of x that's - 2 into f (x) that is for every x in f (x) replace it with - 2
So we have
f(-2) = 3(-2) - 2
= - 6 - 2
We have the final answer as

The measure of the supplement of an angle is twice the measure of the angle. What is the measure of each angle?
Answer:
120° and 60°
Step-by-step explanation:
Suplementary angles sum 180°
then:
a + b = 180°
b = 2a
then:
a + 2a = 180°
3a = 180°
a = 180/3
a = 60°
b = 2a
b = 2*60
b = 120°
Check:
120° + 60° = 180°
