Answer:
slope- 9 y-intercept- -7
Step-by-step explanation:
y=mx+b
m=slope
b=y-intercept
Since x represents the length (in meters), the width, which is 7 meters greater, is x +7. The product of these dimensions is the area (in square meters):
x(x +7) = 170
In standard form, the quadratic is ...
x² +7x -170 = 0
Adding 6 to both sides and taking the square root, remember that x can be the poitivie and negative root
x^2-6=0
add 6
x^2=6
squaer root both sides
x=√6
x=+√6 and -√6
Answer:
$240
Step-by-step explanation:
You are going to want to use the simple interest formula for this. The one below is modified for solving the interest earned.
<em>I = interest amount</em>
<em>P = principal amount</em>
<em>r = interest rate (decimal form)</em>
<em>t = time (years)</em>
<em />
First, change 6% into a decimal:
6% -> -> 0.06
Now, plug in the values:
The interest earned is $240.
Answer:
The coefficient of the term 13a is, 13
Step-by-step explanation:
Coefficient term are the numbers that multiply the variables or letters
In the given expression:
13a means 13 times a , and a is the variable,
so 13 is the coefficient .
6b means 6 times b , and b is the variable ,
so 6 is the coefficient .
therefore, the coefficient of the term 13a in the given expression is, 13.
