The polynomial y = x2 - 5x + 4 has a repeated factor. (It may help to graph the equation.)

1 answer:

5 0

SOLUTION:

y = x^2 - 5x + 4

y = x^2 - 4x - x + 4

y = x ( x - 4 ) - ( x - 4 )

y = ( x - 4 ) ( x - 1 )

ANSWER:

Therefore, the answer is:

A. True.

Ken has read 1/3 of his book what fraction of his book is left to read?

Stells [14]

Answer:

2/3

Step-by-step explanation:

fraction of book already read = 1/3

fraction which represents whole book = 1 = 3/3

fraction of remaining book = fraction of whole book - fraction of book already read

= 1 - 1/3

= 3/3 - 1/3

= (3-1) /3

= 2/3

PLS HELLPPPP with a good and simplified explanation just 7th grade.

umka21 [38]

Answer:

1 / 10 (1 : 10) (10%) - your teacher has probably given you some idea as to the formatting of how you should write probability [so 3 different ways are written here], but I suspect they expect you to write it as 1 / 10

Step-by-step explanation:

only 1 out of all of these 10 trials is a "success" (aka what we are looking for)

we know that 7 matches the criteria of all years seeing a groundhog, and that all other options (1 , 2 , 3 , 4 , 5 , 6 , 8 , 9 , 10) do not meet this criteria.

so, the experimental probability** is 1 / 10 (or 1 : 10) (1 / 10 = 10%)

**: experimental probability is about how many times something happens in the experiment--not theoretically. it means that if his life was destined to be 1 of the 10, the probability of his experience matching the criteria is 1 / 10

experimental probability can be thought of as

successes / possible outcomes

In order for a gear to work in a piece of machinery, the radius of the gear, r, must be greater than 4 cm, but not exceed 4.1 cm

Arturiano [62]

I’m pretty sure it’s 4 < r < 4.1

Please help me with this geometry question, Im pretty sure you need to use SAS congruence rule

Ierofanga [76]

Congruent triangles are two or more triangles with the same length of sides and measure of internal angles. Thus the required proof is as shown below:

From the given diagram, it can be observed that:

AB = AC (similar property of two lines)

AC = AE (similar property of two lines)

Also,

m<A is a common angle to ΔABC and ΔADE

So that it can be concluded that;

ΔABC ≅ ΔADE (Side-Angle-Side property)

Thus since ΔABC ≅ ΔADE are congruent, then;

BC = DE (corresponding sides of congruent triangles)

QUESTION 2 21 Write THREE equivalent actions for the following traction 25/50

MrMuchimi

The three equivalent fractions for $\frac{25}{50}$ are, $\frac{1}{2},\frac{5}{10},$ and $\frac{50}{100}$ .

<h3>What are equivalent fractions</h3>

Equivalent fractions are the fractions that have different numerators and denominators but are equal to the same value. For example, $\frac{2}{4}$ and $\frac{3}6}$ are equivalent fractions, because they both are equal to the $\frac{1}{2}$ . A fraction is a part of a whole. Equivalent fractions represent the same portion of the whole.
