Y = -0.4x

1) It is a straight line
2) I passes through the origin (0,0), because the y-intercpet is 0.
3) The slope is negative, so it passes throuh II and III quadrants
4) The magnitude of the slope = 0.4
4) The angle of the line with the negative side of the x-axis is that whose tan is 0.4 => angle = 21.8 °

With all that information you can identify the graph, given that you didn't include the options.

Answer:

Step-by-step explanation:

From the given table, we have:

$y_{2}=4x^2$

⇒ $a=4(1)^2$

⇒ $a=4$

$y_{3}=4^x$

⇒ $b=4^1$

⇒ $b=4$

$y_{1}=4x$

⇒ $c=4(2)$

⇒ $c=8$

$y_{3}=4^x$

⇒ $d=4^2$

⇒ $d=16$

$y_{1}=4x$

⇒ $e=4(3)$

⇒ $e=12$

$y_{2}=4x^2$

⇒ $f=4(3)^2$

⇒ $f=36$ and

$y_{3}=4^x$

⇒ $g=4^3$

⇒ $g=64$

Therefore, the value of a,b,c,d,e,f and g is 4,4,8,16,12,36 and 64 respectively.

Answer:

There are 76 students:

g + b = 76

girls is 13 more than twice the boys:

g = 2b + 13

replace g with 2b + 13 in 1st equation

2b+13+b = 76

3b + 13 = 76

3b = 63

b = 21 boys

g = 76-21 = 55 girls

neonofarm [45]

Answer:

48/8=6 bags of chocolate chip cookies.

And 64/8=8 bags of vanilla wafer cookies.

8 bags.

Step-by-step explanation:

Linda is having a bake sale:

48 chocolate chip cookies and 64 vanilla wafer cookies to put in bags

She can fill the bag with same number of cookies and the same number of wafers in each bag

And condition is no wafers or cookies left over.

So, we will find the greatest common factor of 48 and 64 which is 8

Hence, she can fill 8 bags

And 48/8=6 bags of chocolate chip cookies.

And 64/8=8 bags of vanilla wafer cookies.
