A. The data in the table represent a function. y=x/2. This is seen as for every value of x in the table, y=x/2(half of it). You can show this further by trying this fact on each value.

B. For the original function, when x =8, y=x/2=4
For the function given in this part, when x=8, y=3(8)-10
y=24-10 y=14
This means the relation given in this part has a greater value when x=8

C. When x=80, f(x)=3(80)-10
=240-10
=230

Solve the following equation. Then place the correct number in the box provided. x/9 = 1

BARSIC [14]

First, we need to isolate the variable x.

To isolate x, we simply need to multiply both sides by 9, which would result in x = 9

From Alexa's eyesight to the top of the tree has an angle of 56.789 degrees and its distance of 23.45 feet. Match the following

Marat540 [252]

Answer:

Distance between Alexa and tree = 12.844 ft

Height of tree = 19.620 + height of eyesight from ground

Perimeter of triangle formed = 55.914 ft

Step-by-step explanation:

From the given data, the attached image is drawn ( refer attachment)

Assume

Height of eye line as $h_{A}$ , height of tree as $h_{T}$ , distance of tree from Alexa as X and vertical distance between eye line and top of tree is y.

To find: distance of tree from Alexa

consider triangle ATE. Here

X = 23.45 * cos ( $56.789^{o}$ ) = 12.844 ft

y = 23.45 * sin ( $56.789^{o}$ ) = 19.620 ft

Hence distance of tree from Alexa = 12.844 ft

Height of tree $h_{T}$ = y + $h_{A}$

= 19.620 + $h_{A}$

Perimeter of triangle = X + Y + 23.45 ft

= 12.844 ft +19.620 ft + 23.45 ft

= 55.914 ft

Through: (1,-1), parallel to y = -3

zheka24 [161]

Answer:

The equation of a line parallel to the line and passing through (1, -1) is:

$y=-3x+2$

Step-by-step explanation:

Given the line

y = -3

We know that the slope-intercept form of the line equation is

$y=mx+b$

where m is the slope and b is the y-intercept

Thus, the slope of the equation y=-3 will be m = -3

We know that the parallel lines have the same slopes.

Thus, the slope of the parallel line will also be -3.

Thus, using the point-slope form to find the line equation is

$y-y_1=m\left(x-x_1\right)$

substituting the values m = -3 and the point (1, -1)

y-(-1) = -3(x-1)

y+1 = -3x+3

y=-3x+3-1

y=-3x+2

Thus, the equation of a line parallel to line and passing through (1, -1) is:

$y=-3x+2$

A husband and wife have normal vision, although both of the couple's fathers are red–green color-blind, an inherited X-linked re

Mekhanik [1.2K]

Answer:

1/2

Step-by-step explanation:

Since the recessive gene is carried in the x chromosome and a father can only pass it to a daughter, the father doesn't have the disease nor carries it.

The mother carries the recessive gene because her father passed her his conditioned gene (only having one x chromosome), while her mother gave her a normal one so she can have normal vision.

The chance of having a boy or a girl is 1/2 and the chance of this baby of having both recessive gene is null because in order to have a girl that is color blind both her x chromosomes must have the recessive gene, but the father can't pass it since he doesn't carries it. Therefore the combined probability is 1/2*(1-0) = 1/2.

How can proportional relationships be identified in tables and graphs?

GalinKa [24]

Answer:

A proportinal relationship can be represented in different ways. For instance, a ratio table, a graph of astraight line though the origin, also an equation of the form y=mx, where m is constant in proportinality.

I apologize if I didn't follow the sentence starter.

Hope this helps!
