Answer:

5 \frac{1}{2}

Step-by-step explanation:

The slope of the line is given by \frac{\Delta y}{\Delta x} = \frac{(-4) - (7)}{(-6) - (-4)} = \frac{-11}{-2} = 5 \frac{1}{2}.

A line passes through A(3,7) and B(-4,9) find the value of a if C (a 1) is on the line
Xelga [282]
What we need to do first, is to write the equation of the line through points A and B. 


the slope of the line through A(3, 7) and B(-4, 9) is 

m= \frac{9-7}{-4-3}= \frac{2}{-7}=- \frac{2}{7}


the equation of the line is :

y-7=- \frac{2}{7}(x-3)\\\\y-7=- \frac{2}{7}x+ \frac{6}{7}\\\\y= - \frac{2}{7}x+ \frac{6}{7}+ \frac{49}{7}\\\\y=  - \frac{2}{7}x+ \frac{55}{7}


C(a, 1) is on this line so it must satisfy the equation:

y=  - \frac{2}{7}x+ \frac{55}{7} \\\\1=  - \frac{2}{7}a+ \frac{55}{7}\\\\ \frac{2}{7}a= \frac{48}{7}\\\\2a=48\\\\a=24

Nataliya [291]

I’m pretty sure the answer is 160 because the rectangle on the top has a volume of 64(16 x 4) and the rectangle on the bottom has a volume of 96(2 x 4 x 12). Add those together and you get 160 cubed inches. Hope this helped :)
