How do you set up factor by grouping for the
polynomial:

Answer:

2x+15=5y

y=(2x+15)/5

hope this helps

Answer:

[tex]y = \frac{2}{5} x + 3[/tex]

Step-by-step explanation:

2x - 5y = -15

Firstly, you will need to isolate the variable you are solving for, in this case, y.

2x - 2x - 5y = -15 - 2x

-5y = -15 - 2x

-5y/-5 = -15/-5 - 2x/-5

A negative divided or multiplied by a negative is positive.

[tex]y = 3 + \frac{2}{5} x[/tex]

Rearrange.

[tex]y = \frac{2}{5} x +3[/tex]

Answer:

50°

Step-by-step explanation:

The sum of angles in a triangle is 180 degrees

Hence given that in a triangle ACB with angles 90°, 4x°, 7x - 20

As such

90 + 4x + 7x -20 = 180

simplify

11x + 70 = 180

11x = 180 - 70

11x = 110

Divide both sides by 11

x = 110/11

x = 10

m∠ACB is 7x - 20

Substitute the value of x into the expression

= 7(10) - 20

= 70 - 20

= 50

Answer:

The answer is 50 degrees

Answer:

[tex]f(1)=-6[/tex]

[tex]f(n)=f(n-1)(-3)[/tex]

Step-by-step explanation:

We are given that

[tex]f(n)=2\cdot (-3)^n[/tex]

We have to complete  the recursive formula of f(n).

Substitute n=1

[tex]f(1)=2\cdot (-3)[/tex]

[tex]f(1)=-6[/tex]

[tex]f(2)=2\cdot (-3)^2=18[/tex]

[tex]f(3)=2\cdot (-3)^3=-54[/tex]

[tex]\frac{f(2)}{f(1)}=\frac{18}{-6}=-3[/tex]

[tex]\frac{f(3)}{f(2)}=\frac{-54}{18}=-3[/tex]

It forms geometric sequence because the ratio of two consecutive terms are equal.

Therefore, the recursive formula

[tex]f(n)=f(n-1)r[/tex]

[tex]f(n)=f(n-1)(-3)[/tex]

Answer:

f(1) = -6

f(n)= f(n−1)⋅ -3

ASA (Angle-Side-Angle)ASA: Two pairs of corresponding angles and the corresponding sides between them are equal. hope this helps you. means similarity would be equal.. I cannot read your paragraphs that well they are too small but I hope this helps you just got to find which paragraph it shows that they AA and AAS a are similar to each other by being equal

Answer:

90 degrees

Step-by-step explanation:

classmate is muy stupio

the non 90 degree angles are all congruent

which means each of them are 45 degrees

cuz triangle degree add up to 180

then

u use subtraction

cuz a line is 180 degrees

the the answer is SAS

Answer:

the correct option is B. 2

Step-by-step explanation:

As given,

x + [tex]\frac{b}{na}[/tex] = ± √b²-4ac

⇒x = -[tex]\frac{b}{na}[/tex] ± √b²-4ac

As e know that the quadratic formula is

x = [tex]\frac{-b + or - \sqrt{b^{2} - 4ac } }{2a}[/tex]

So , by comparing with the formula

we get

n = 2

So, the correct option is B. 2

Answer:

5/8, -5/8

Step-by-step explanation:

64x^2 = 25

divide both sides by 64

x^2 = 25/64

take the square root of both sides, and the negative square roots

Answer:

x = 5/8=0.625 and x = -5/8=−0.625

Step-by-step explanation:

f(x)=64x^2+6=31

Subtract 6 from both sides.

64x^2+6=31

Subtract 6 from 31 to get 25.

64x^2=25

Divide both sides by 64.

x^2=25/64

Take the square root of both sides of the equation.

x=5/8=0.625

x=-5/8=−0.625

Answer:

Number line graph with closed circle on 24 and shading to the right.

Step-by-step explanation:

First, the graph has to have a closed circle on only 24.

Since she has $61 and needs at least $85 to buy a skateboard, she needs to have at least $24 saved to buy one.

This means the last 2 answer choices are wrong, because there cannot be shading in between.

The first answer choice is also wrong because it puts a open circle, instead of a closed one, on 24.

So, the correct answer is Number line graph with closed circle on 24 and shading to the right.

Answer:

$0.2

Step-by-step explanation:

1% of $40

1/100 * 40

0.01 * 40 = $0.4

Half of $0.4

$0.4 / 2 = 0.2

Therefore, half of 1% of $40 equals $0.2

Answer:

24, 26, 28

Step-by-step explanation:

The final number is 78

first we can divide 78/3= 26

so 26+26+26= 78

we can leave the middle 26 but we can give 2 from the first number to the last number

24+26+28=78

Answer:

  see attached

Step-by-step explanation:

The points form a right triangle. The circumcenter is the midpoint of the hypotenuse of a right triangle. Here, that is the midpoint of AC:

  O = (A +C)/2

  O = ((1, 1) +(10, 8))/2 = (11, 9)/2 = (5.5, 4.5)

The circumcenter is (5.5, 4.5).

Answer:

Left: yes it is linear

Right: No it is not.

Step-by-step explanation:

Left Problem

The table on the left is linear. It's general form is

y = 6x + 7

x = 5

y = 5*6 + 7

y = 37

-------------------

x = 8

y = 6*8 + 7

y = 48 + 7

y = 55

------------------

y = 6*12 + 7

y = 72 + 7

y = 79

=============

Right Problem

The right problem looks like it is linear. It is not, I don't think. Do the same thing you did above.

y = 62x

x = 2

y = 2*62

y = 124

-----------------------

y = 62x

x = 6

y = 62 * 6

y = 372

---------------------

y = 62*x

x = 9

y = 62 * 9

y = 558            

It should be 558 not 552
