2.) Consider the quadratic equation 6x^2+11x-10=0

A.) solve it by using zero product property

Step-by-step explanation:

numbers divisible by 2 end with an even number (2,4,6,8,0)

numbers divisible by 5 end with either 5 or 0

Answer:

A,D, and F

Step-by-step explanation:

Any number that is even is divisible by 2.

A D and F are even numbers. If a number ends in 2,4,6,8, or 0 then it is an even number, so you can just look at the last number and determine weather it is divisible by 2.

Answer: The second option would be the answer

Step-by-step explanation:

Factoring the number is just listing all the whole numbers it can be divided by, and in this case it includes the variable. 16a is dividable by 1, 2, 4, 8, 16, and a; since 16a / a = 16. Apply this to 18b, and 1, 2, 3, 6, 9, 18, and b.

Answer:

To prove V is a subspace of R, you must show:

(1) It is not empty

(2) Adding vectors returns real numbers

(3) Multiplying by scalars return real numbers

2 & 3 follow the conditions that x,y must be real.

===

(1):

0 = 0 + 0 , therefor V cannot be an empty set. Really thats it.

===

(2)

Let u=(u1, u2 , 2u1-3u2)

Let v *lowercase =(v1, v2, 2v1-3v2)

Great, now lets add them. This isn't intuitive unless you finish reading it all.

u+v = ( u1 + v1 , u2 + v2 , 2u1 - 3u2 + 2v1 - 3u2 )

--> u + v = [ (u1+v1), (u2+v2) , (2u1 + 2v1) + (-3u2 - 3v2) ] (got like terms kinda)

====> All must equal (x,y, 2x-3y)

... which means x=u1+v1 & y=u2+v2 (you compare u+v to V for this)

===

(3)

Let c be a real number.

C(u) = (Cu1, Cu2, C2u1 - C3u2)

====> Must equal (x,y, 2x-3y)

... which means Cu1 = x & Cu2 = y

Cu is in V (because x,y are)

-> V is a subspace of R3.

Answer: 32

Step-by-step explanation:

We can write the problem like this:

[tex]\frac{75}{100}x=24[/tex]

Then, we can multiply 100 to the equation:

[tex]75x=2400[/tex]

Now, we can divide 2400 and 75:

[tex]x=32[/tex]

Now we can conclude that the amount of students is 32.

Answer:

35!

Step-by-step explanation:

5squared is 25 so you then do 25+10 wich = 35!

Answer:

B

Step-by-step explanation:

The volume of the cube is the total amount of cubes in the box.

Because the box is a cube, and you know the formula for volume of cube is  L³

L³=125

∛L³=∛125

L=5

there would be 25 cubes in each layer, not 125. Because one layer is L²

Answer:

Answer:

A,B

Step-by-step explanation:

9 bags sorry for the other answer

she has 7 boxes at home, then she goes and buys 6 more from the store, now she has 7 + 6 = 13 boxes of chips, each box of chip has 13 bags, so the total amount of potato chips I guess is 13 * 13 = 169 bags total.

So she split it even among her 9 students, so how many times does 9 go into 169?  169 ÷ 9, has a quotient of 18 with a remainder of 7.

18 * 9 = 162, plus 7 = 169, which is the total amount of potato chips bags.

Q3:

b) 2

c) 1

d) 2

e) 3

Step-by-step explanation:

for q3 u have to look the number before the dot and then add 1 to it

as for q 4 the decimal numbers are those number which are after the dot for example if ur number is 4.5 u have only one number after the dot THAT is ur decimal number, by the way even if there is a 0 after the dot it is still counted as decimal number

Answer:

( -2 , 1 )

Step-by-step explanation:

Add the 2 equations downwards.

( -x+4y=6 ) + ( 2x-y=-5 )...consider the sign of each term.

= x + 3y = 1

Put -2 in x because that's where the graph above shows an intersection of the 2 equations.

-2 + 3y = 1

3y = 3

y = 1.

( x , y) = ( -2 , 1 )

Answer:

Step-by-step explanation:

The formula for the area of a circle is [tex]A = \pi r^{2}[/tex]

Since your radius was given (15 in) the area is:

[tex]A=\pi (15)^{2} =225\pi =706.86 in^2[/tex]

Answer:

c

Step-by-step explanation:

the number goes to both of the numbers in the equation

Given :

⠀

To Find :

⠀

Solution :

We know that,

[tex]\qquad { \pmb{ \bf{Length \times Width = Area_{(rectangle)}}}}\: [/tex]

So,

Let's assume the width of the rectangle as x and the length will be (x + 2).

⠀

Now, Substituting the given values in the formula :

[tex]\qquad \sf \: { \dashrightarrow (x + 2) \times x = 48 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow {x}^{2} + 2x = 48 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow {x}^{2} + 2x - 48 = 0 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow {x}^{2} +8x -6x- 48 = 0 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow {x} (x +8) -6(x+8) = 0 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow (x +8) (x - 6) = 0 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow x = -8, \: \: x = 6 }[/tex]

⠀

Since, The width can't be negative, so the width will be 6 which is positive.

⠀

[tex]\qquad { \pmb{ \bf{ Width _{(rectangle)} = 6\:ft}}}\: [/tex]

[tex]\qquad { \pmb{ \bf{ Length _{(rectangle)} = 6+2=8 \: ft}}}\: [/tex]

mixed number

Step-by-step explanation:

1. To DECOMPOSE is to break apart a number.

e.g. to decompose 853:  800 + 50 + 3

2. The NUMERATOR is the top number in a fraction (the bottom number is the denominator).

3. A number that has whole number part and fraction part is a MIXED NUMBER, e.g. [tex]6\frac23[/tex]

Graphs are used to represent functions and equations

The best value of x is x = 5

From the question, we understand that x represents the unit of calculating the resale in plot million of rands

This means that x cannot be negative.

So, we have x = 2 and x = 5

The graph is not given.

So, we can assume that the graph is a linear function with a positive slope

For a linear function with a positive slope, the higher the x value, the higher the output value

Hence, the best value of x is x = 5

Answer:

Yes and no

Step-by-step explanation:

Prime numbers greater than 2 are always odd because if they were even they would be divisible by 2, becoming composite. Not all composite numbers are even, some may be a multiple of two odd numbers. For example, 21 = 3*7
