Are these proportional? And I need to show work sooo for example on the first question we did in class we wrote down
Eva8 [605]

Answer:

Step-by-step explanation:

If y is proportional to x,

y ∝ x

y = kx

k = \frac{y}{x}

Here, k = Proportionality constant

For y = -8 and x = -4,

k = \frac{-8}{-4}

k = 2

For y = -4 and x = -2

k = \frac{-4}{-2}

k = 2

For all values of x and y proportionality constant = 2.

For x = 0 and y = 0,

If we graph a line passing through these points, the line will pass through the origin (No y-intercept).

And we know that any line passing through the origin represents the proportional relation between x and y variables.

Therefore, given table represents the proportional relation.

Find the area of the figure. Round to the nearest tenth if necessary. Use 3.14 for .
Anna [14]

Answer:

22\ units^2

Step-by-step explanation:

we know that

The area of the figure is equal to the area of a triangle plus the area of a parallelogram

<em>Find the area of triangle KLM</em>

A=\frac{1}{2} (b)(h)

we have

b=7-3=4\ units --> difference of the x-coordinates points M and K

h=6-3=3\ units --> difference of the y-coordinates points L and K

substitute

A_1=\frac{1}{2} (4)(3)=6\ units^2

<em>Find the area of parallelogram JKMN</em>

A=(B)(H)

B=6-2=4\ units --> difference of the x-coordinates points N and J

H=3-(-1)=4\ units --> difference of the y-coordinates points K and J

substitute

A_2=(4)(4)=16\ units^2

The area of the figure is equal to

A=A_1+A_2

A=6+16=22\ units^2

In a particular class of 28 students,8 students are men what fractions of the students is female in the class
WITCHER [35]
20/28 are female. Since there are 8 male students you just have to subtract 28-8 and you'll get the female total.
