Since every day he gets 14 dollars, he answer would be 14x, meaning that every day, he gets 14 more dollars. Just in case you were wondering also, the r is the 31 dollars he already has
Answer:
48% for number 1
step-by-step explanation :
All you have to do is divide the numerator by the denominator and then multiply that result with 100 like so
Width=x-6
lenght=x
Perimeter of a parallelogram=2(lenght)+2(width)
Data:
Perimeter=60 m
Therefore:
2(x)+2(x-6)=60
2x+2x-12=60
4x=60+12
4x=72
x=72/4
x=18
Width=x-6=18-6=12
Lenght=x=18
Answer: the lenght would be 18 m, and the width 12 m
Slope =(9-7)/(4-3) = 2
equation
y - 7 = 2(x - 3)
y - 7 = 2x - 6
y = 2x + 1 .....this is slope intercept form
2x - y = = -1 .....this is standard form
<u><em>Answer:</em></u>The factored form is: (x-2)(x-4) = 0
<u><em>Explanation:</em></u>To factor an expression, we need to <u>get its solutions</u>.
<u>The standard form of the quadratic equation is:</u>
ax² + bx + c = 0
<u>The given equation is:</u>
x² - 6x + 8 = 0
<u>By comparison:</u>
a = 1
b = -6
c = 8
Now, to get the roots, we will substitute with the values of a, b and c in the quadratic formula shown in the attached image.
<u>This will give us:</u>
either x =
![\frac{6+ \sqrt{(-6)^2-4(1)(8)} }{2(1)} = 4](https://tex.z-dn.net/?f=%20%5Cfrac%7B6%2B%20%5Csqrt%7B%28-6%29%5E2-4%281%29%288%29%7D%20%7D%7B2%281%29%7D%20%3D%204)
This means that
the first factor is (x-4)
or x =
![\frac{6- \sqrt{(-6)^2-4(1)(8)} }{2(1)} = 2](https://tex.z-dn.net/?f=%20%5Cfrac%7B6-%20%5Csqrt%7B%28-6%29%5E2-4%281%29%288%29%7D%20%7D%7B2%281%29%7D%20%3D%202)
This means that
the second factor is (x-2)
Based on the above, the factored form would be:
(x-4)(x-2) = 0
Hope this helps :)
