Answer:
D. a person cannot find the money to pay their monthly bills
(7x² − 8x − 4) + (-2x² + 3x + 5) + (5x²<span> - 10x - 8) =
</span>7x² − 8x − 4 - 2x² + 3x + 5 + 5x² - 10x - 8 =
10x² -15x -7
Answer:
no
Step-by-step explanation:
Assuming the wall makes a 90-degree angle with the ground, the ladder is the hypotenuse of a right triangle whose legs are the ground distance, the wall height, and whose hypotenuse is the ladder length.
The hypotenuse of a right triangle must be longer than either side. If one side is length 13 and one side is length 5, the hypotenuse must be about 13.93. A 13-ft ladder will not do.
Hey there! :)
-7x - 4y = -8
To find the slope, we must turn this equation into slope-intercept form.
Slope-intercept form is : y=mx+b ; where m=slope, b=y-intercept
To get here, we must isolate y by adding 7x to both sides of our original equation.
-7x + 7x - 4y = 7x - 8
Simplify!
-4y = 7x - 8
Then, divide both sides by -4.
-4y ÷ -4y = (7x - 8) ÷ -4y
Simplify!
y = -7/4x + 2
Congrats, we got y isolated! Now, review the slope-intercept form equation to figure out what our slope & y-intercept are.
After reviewing our slope intercept form equation, we can come to the conclusion that -7/4 is our slope because it's in the "m" value slot, and 2 is our y-intercept because it's in the "b" spot.
So, our answer is :
Slope = -7/4
Y-intercept = 2
Hope this helped! :)
The formula in getting the arithmetic sequence:
an = a1<span> + (n – 1)d.
</span>
We can substitute the values in order for us to know how many terms the sequence has.
an = 7373
a1 = 1313
d = 303
an = a1<span> + (n – 1)d
</span>7373 = 1313 + (n-1) 303
7373 = 1313 + 303n - 303
-303n = 1313 - 303 - 7373
303n = -1313 + 303 + 7373
303n = 6363
n = 21
So, there are 21 terms in the sequence given.
