Sorry, there is not any square root of -1.
Thank you♥♥
Rearrange the equation into slope intercept form
7x+3y=18
3y=-7x+18
y=-7x/3+18/3 so the slope of the reference line is -7/3
To be perpendicular to this line the slope must be the negative reciprocal of this...mathematically m1*m2=-1. So the slope of our perpendicular line is:
-7m/3=-1
-7m=-3
m=3/7 so our line so far is:
y=3x/7+b, using point (6,8) we can solve for b, the y-intercept
8=3(6)/7+b
8=18/7+b
56/7-18/7=b
38/7=b so our line is:
y=3x/7+38/7 or if you prefer
y=(3x+38)/7
<span>yes it is a true equation.. you can solve it to find q ...
-5(3-9) 4 = 5q - 11
</span><span>−5 *−6 * 4= 5q−11</span><span>120 = 5q−11
120 + 11 = 5q
131 = 5q
q = 131/5
in decimals q = </span><span> 26.2 ..

Hope it helps!!!!

Simply plug in numbers!! (3x-1)(5)=55
15x-5=55
15x=60
x=4
hope this helps :)
Answer:
Q1 A Scatter plot. Q2
Step-by-step explanation:
Q1. We have a data set containing values of car and age group, if we plot value of the car on y-axis and the age on x, it is logical that two different age groups can own a care with same value, so we can have two values on x corresponding to one value on the y-axis, if we can use scatter plot to visually depict this data.
Q2 50 couples with bride age and groom age , here we can take age difference and number of couples that fit in the catogery, a two way table can be used to describe this data(two columns ).
