Factor the trinomial, or state that the trinomial is prime,
y2 - 5y + 6

Answers

Answer 1

Answer:

Im doing this for the points lol

Sorry

Answer 2

Answer:

factorise it

Step-by-step explanation:

in the method ax2 + bx + c

so it can be done just in y

find a common factor

well there isn't one but we can see that we need to factorise it

+1 y2 times 6= 6

because there is only 1 y and you times it by 6

you'll see why when we factorise this

so x the squared number (1) x 6 =6

and the middle number is 5

find two numbers that

x multiply to make six

and add+ to make -5

those numbers are

-3

-2

because -2 + -3 = -5 and -2 x -3 = positive 6

so our answer of y2 + 5y + 6

is identical to = y2 -3y -2y +6

factorise in half

y2 -3y -2y +6

so now we can factorise!

in this bracket we have

a common factor of y in this bracket we have common

factor of 2

= y (y -3) + = -2(y-3)

BUT THERE IS STILL ONE MORE

THEN WE CAN SEE A COMMON FACTOR OF Y-3

put the (y-3) in front and the (-y-2) is left

put y from first bracket and -2 from second bracket into a seperate bracket

yay! factorised

BUT THERE IS STILL ONE MORE

ANSWER = (Y-2) (Y-3)

you can use the rainbow multiplying out of bracket method to prove it works.

PLZ GIVE BRAINLIEST

how it would be written out:

y2 + 5y + 6

y2 -3y -2y +6

y (y -3) -2(y-3)

(Y-2) (Y-3)

6x (3x +11)create an equivalent expression with the fewest terms possible

Answers

Answer:

18x^2 + 66x

Step-by-step explanation:

Apply the distributive property of multiplication:

6x (3x +11) becomes 18x^2 + 66x

The equivalent expressions for given expressions is 18x²+66x.

The given expression is 6x(3x +11).

What is an equivalent expression?

Equivalent expressions are equivalent expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.

The equivalent expressions for given expressions can be determined as follows

Using distributive property 6x(3x +11)

= 18x²+66x

Therefore, the equivalent expressions for given expressions is 18x²+66x.

Answer:

Midsegment theorem:

Midsegment of a triangle is half the length of the third side in order to fill in the triangle.

So, the perimeter of a midsegment tirangle is half the perimeter of QRS.

Perimeter of QRS:

For finding out it's perimeter sum up all the sides while adding alike variables together.

=> (2x + 5) + (3x - 1) + (5x)

= 2x + 3x + 5x + 5 - 1

= 10x + 4

Perimeter of mid-segment triangle:

Perimeter of QRS divided by 2

[tex] \implies \mathsf{ \frac{10x + 4}{2} }[/tex]

= 5x + 2

Step-by-step explanation:

1. To find the sum of two integers with like signs simply add them and keep the sign same as integers

for example:

Answers

Step-by-step explanation:

there is no big "trick" involved.

you just need to do the multiplication and then move the terms into the right spot, so that the x-, y- and constant terms are in the same place as the generic Ax + By = C

y + 5 = 4(x + 1)

y + 5 = 4x + 4

-4x + y = -1

or (after multiplying both sides by -1)

4x - y = 1

yes, B = 1 (or -1), so you could write 1y (or -1y) instead of only y (or -y).

but nobody does that.

A linear equation is in the form:

1. what is the value of x?
2. what would be the measurement of the top angle of the triangle?
please help

Answers

Hello there. So that triangle is called an isosceles. You can tell because of the two lines on either side, they remind you that opposite sides are equal. So in this case, x would be 75 because both sides are equal.

For part 2, we already know 2 angles. 75 and 75. If we add them together, we get 150. Angles in a triangle add up to 180 degrees. So in that case, 180 - 150 will give us 30 degrees. So the missing top angle must be 30 degrees.

Rida and Elisa are each paid by the hour. Rida worked 5 1/2 hours and earned 77. Elisa worked 3 3/4 hours and earned 60. Whose hourly rate is greater?

Answers

Answer:

The answer is Elisa's Hourly rate

Step-by-step explanation:

Rida and Elisa are each paid by the hour.

Rida worked 5 1/2 hours and earned 77.

5 1/2 = 11/2 = 5.5 Hours

Rida earned 77 in 5.5 hours

Elisa worked 3 3/4 hours and earned 60.

3 3/4 = 15/4 = 3.75 Hours

Elisa earned 60 in 3.75 hours

Elisa earns more than in less time as compared to Rida

so Elisa's hourly rate is greater than Rida

Thus, The answer is Elisa's Hourly rate

-TheUnknownScientist 72

Step-by-step explanation:

we find out by checking how much they got for 1 hour.

so, 77 earned in 5 1/2 hours. how much in only 1 hour ?

77 / (5 1/2) = 77 / 11/2 = 77 × 2/11 = 7×2 = 14

and 60 earned in 3 3/4 hours. how much in 1 hour ?

60 / (3 3/4) = 60 / 15/4 = 60 × 4/15 = 4×4 = 16

so Elisa's hourly rate is greater.

Answers

Answer: See below

y=(4/3)x-5

Step-by-step explanation:

The basic form of an equation of a straight line in slope intercept form is y=mx+b, where m is the slope and b the y intercept (the value of y when x=0):

1) slope=4/3, y-intercept=-5 .

y = mx + b: y=(4/3)x-5

2) slope =-5, y-intercept =1.

y = mx + b: y = -5x+1
