Does the graph of the equation y = 7 - 2x increase or decrease? A) decreases because the x values decrease from left to right B)

Nutka1998 [239]

Y=mx+b
m=slope=rise/run
if slope>0, then it increases
if slope<0, then decreases because it is going down

y=7-2x
y=-2x+7
-2<0
decreasing
because the y values decrease from left to right
the x values always increase if you go from left to right

B is the answer

you burn 10 calories each minute you jog.What integer represents the change in your calories after you jog for 20 mins

Hoochie [10]

The total calories burnt in 20 minutes are 200

Step-by-step explanation:

We have to do simple multiplication to find the number of calories burnt.

Given

Number of calories burnt in one minute = c = 10

Time = t = 20 min

So the total number of calories burnt in 20 minutes will be:

$C_t = c * t\\= 10 * 20\\=200\ calories$

Hence,

The total calories burnt in 20 minutes are 200

the altitude of the hypotenuse of a right triangle divides the hypotenuse into segments of lengths 14 and 8. what is the length

lisov135 [29]

Answer:

B. $4\sqrt{7}$

Step-by-step explanation:

The right triangle altitude theorem states that the altitude of a right angled triangles formed on the hypotenuse is equal to the geometric mean of the 2 line segments it creates.

This can be represented as:

$h = \sqrt{(xy)}$

Where,

h = the length of the altitude,

x and y are the lengths of the 2 segments formed.

Therefore, the length of the altitude = $h = \sqrt{(14*8)}$

$h = \sqrt{112}$

$h = \sqrt{16}*\sqrt{7}$

$h = 4\sqrt{7}$

The graph below displays the wrist circumferences and heights of six students in Alyssa’s classroom.

coldgirl [10]

Answer:

Option D(No because the wrist circumference of 16 cm is paired with two heights.

Step-by-step explanation:

In the given graph we have set of points representing the wrist circumferences and heights of six students in Alyssa’s classroom.

x axis represents the wrist circumference while y axis represent the height.

Any relation is called a function if for one value of x we have only one value of y. If the graph passes the vertical line test that is if a vertical line drawn touches the graph at only one point then the graph is called a function.In the given graph for x value x=16 there are two y values 162 and 165.So the graph is not a function.

Among all the options Option D(No because the wrist circumference of 16 cm is paired with two heights.) is the right answer.
