Answer:

A straight line passing through the origin

Step-by-step explanation:

A proportional relationship will have a particular quantity being related to another

For example, the relationship might be inverse or direct

In this case, we can have a straight line graph that passes through the origin

A straight line graph that passes through the origin would show the proportional relationship as it has no slope whatsoever

Find the output, k, when the input, t, is -7−7minus, 7. k = 10t-19k=10t−19

sleet_krkn [62]

The value of k is -89

Explanation:

The given expression is $k=10t-19$

We need to determine the output k, when the input t is -7

Output k:

The value of the output k can be determined by substituting the input $t=-7$ in the expression $k=10t-19$

Thus, we have,

$k=10(-7)-19$

Multiplying the terms 10 and -7, we have,

$k=-70-19$

Simplifying, we get,

$k=-89$

Thus, the value of k is -89

Help me please with this question

Gelneren [198K]

You could go both ways with this question, and they're both true:

-- circle "greatest" in both places;

-- circle "least" in both places; also true, but whatever the numbers are,
their least common factor is always ' 1 ', so it's not very useful.

Rewrite in simplest terms: -2(5d-9f)+7f-10(-9f-7d)

Afina-wow [57]

Answer:

= 5 ( 12d + 23f )

Step-by-step explanation:

-2(5d-9f)+7f-10(-9f-7d

Open parenthesis

= -10d + 18f + 7f + 90f + 70d

Collect like terms

= -10d + 70d + 18f + 7f + 90f

= 60d + 115f

Factorise

= 5 ( 12d + 23f )

Therefore,

-2(5d-9f)+7f-10(-9f-7d) in its simplest form is 5 ( 12d + 23f )

A point represents a _____.

GalinKa [24]

Answer:

Location.

Explanation:

A point has no physical properties of any sort, so 2 would automatically be out of the question. A point on a number line is represented by a dot, and the location of whatever object you're representing as the dot will be where the dot goes. Therefore, the answer is Location.

Hope this helped!

To qualify for the championship a runner must complete the race in less than 55 minutes ....... Use "t" to represent the time in

Svet_ta [14]

The inequality is t < 55

Solution:

Given that, To qualify for the championship a runner must complete the race in less than 55 minutes

Let "t" represent the time in minutes of a runner who qualifies for the championship

Here it is given that the value of t is less than 55 minutes

Therefore, "t" must be less than 55, so that the runner qualifies the championship

This is represented by inequality:

$t$

The above inequality means, that time taken to complete the race must be less than 55 for a runner to qualify

Hence the required inequality is t < 55
