Answer:
x=5
Step-by-step explanation:
First, find the slope. This is your expression: -8-5/5-5. -8-5= -13, and 5-5 = 0. So, your slope would be -13/0. Since the denominator is a 0, the slope is undefined. That means it's a vertical line. Because it's a vertical line, your equation would just be x=5. Hope this helps!
Both of them would be 3 by using the slope formula
Answer:
The amount it took in 2011 to equal the value of 1 currency unit in 1917 was of 24.091 currency units.
The amount it took in 2019 to equal the value of 1 currency unit in 1917 was of 28.031 currency units.
Step-by-step explanation:
The value needed to equal the value of 1 currency unit in 1917, in x years after 1990, is given by:
a) Use this function to predict the amount it will take in 2011 and in 2019 to equal the value of 1 currency unit in 1917
2011 is 2011 - 1990 = 21 years after 1990, so we have to find V(21).
The amount it took in 2011 to equal the value of 1 currency unit in 1917 was of 24.091 currency units.
2019 - 1990 = 29, so we also to find V(29).
The amount it took in 2019 to equal the value of 1 currency unit in 1917 was of 28.031 currency units.
Answer:
x = -7
Step-by-step explanation:
Seven times a number and seven is equal to six times a number.
Word problems can be tricky no matter what level of math or science you are in.
First look at the question for words that indicate mathematical symbols.
"times" indicates multiplication
"and" indicates addition
"a number" means we have a variable, x, to solve for
Now we can go from left to right and write it in a mathematical equation
7x + 7 = 6x
Then, solve for x
7x + 7 = 6x
7 = 6x - 7x
7 = -1x
7/-1 = x
x = -7
Finally, we check our work.
7x + 7 = 6x
7(-7) + 7 = 6(-7)
-49 + 7 = -42
-42 = -42 √
The answer is x = -7
Answer:
Initial value 4 rate of change is negative 3 over 4
Step-by-step explanation:
Formula to use: y2-y1 over x2-x1 initial value coordinate: 0,4 Crosses thru coordinate: 4,1 1 minus 4 and 4-0 gives you negative 3 over 4
