Answer:

Slope intercept form: The straight line equation is given by:

, .....[1] where m is the slope of the line.

(A)

Let x represents the number of hours and y represents the velocity of the runner.

As per the statement: After one hour, the velocity of the runner is 5 km/h. After three hours, the velocity of the runner is 3 km/h.

we have two points as (1, 5) and (3, 3)

Calculate first slope.

Formula for slope(m) is given by;

Then substitute the given values we get;

Now, substitute the value of m = -1 and (1, 5) in equation [1] we have;

Using distributive property:

Add both sides by 5 we get;

Therefore, an equation in two variables in the standard form that can be used to describe the velocity of the cyclist at different times is,

(B)

x y = 6 -x

1 5

2 4

3 3

4 2

5 1

Now, plot these points on the graph for the first 5 hours as shown below in the attachment.

consider this expression 7+3.4+2 what movements does this represent for Cecil walking on his tightrope? draw a diagram to show h

Lina20 [59]

Ok let me start it from here.

you are studying about properties of natural numbers or whole number or may be integers.

So , In this Question you have to follow property of addition of integers.

⇒7+3=( You are at the point 7 on the number line or on the tight rope , you are moving (+3) on the right direction.) So you will reach at 7+1+1+1=10

⇒4+2=( You are at the point 4 on the number line or on the tight rope , you are moving (+2) on the right direction.) So you will reach at 4+1+1=6

In first case Cecil has taken total walk of 10 units and in second case Cecil has taken a walk of 10 units.

Answer:

$\angle PQR$ , $\angle SQR$ , and $\angle PQS$

angle PQR, angle SQR and angle PQS

Step-by-step explanation:

The three different angles in the diagram are angle PQR, angle SQR and angle PQS.

Another way of writing this is using an angle sign before the alphabets follows. Thus:

$\angle PQR$ , $\angle SQR$ , and $\angle PQS$

If 7 p − 4 = 8 , 7p−4=8, what is the value of p ?

Nookie1986 [14]

Hello!

Let's solve our equation below.

7p-4=8

First we add 4 to both sides.

7p=12

We divide both sides by 7.

p≈1.71

I hope this helps!

Which statement follows from the given theorem? Theorem: The diagonal of a parallelogram divides it into two congruent triangles

Ivenika [448]

Answer:

SSS

Step-by-step explanation:

the dividing line would give the triangles the same length for one side, the side it divided, and then it says the triangles are congruent, meaning they are both the same triangle.
