plzz help pythagorean theorem

Answer:

9x² - 33x + 10

Step-by-step explanation:

Given

(3x - 10)(3x - 1)

Each term in the second factor is multiplied by each term in the first factor, that is

3x(3x - 1) - 10(3x - 1) ← distribute both parenthesis

= 9x² - 3x - 30x + 10 ← collect like terms

= 9x² - 33x + 10

Step-by-step explanation:

-8

hope it helps:-) :-) :-) :-)

Answer:

a = -8

Step-by-step explanation: Subtract 100 on both sides to isolate the variable. From there you will have 11a = -88. If you divide on both sides to cancel them out you will get you answer for the variable -8.

Step-by-step explanation:

oh for the other one

he is right for that one but im right on the other thing for it like it

Both vectors point in the same direction.

The dot product of two vectors is given as,

                   [tex]a\cdot b=ab*cos\theta[/tex]

Where [tex]\theta[/tex] is angle between two vectors.

Given that, [tex]a\cdot b=24,a=4,b=6[/tex]

Substitute values in above relation.

                [tex]24=4*6*cos\theta\\\\cos\theta=24/24=1\\\\\theta=cos^{-1}1=0[/tex]

Thus, both vectors point in the same direction.

Answer:

x=-11/3

Step-by-step explanation:

expand the brackets: 4x+12= 1

this is now a normal equation

solve the equation

-12 from both sides

4x=-11

divide by 4 both sides

x= -11/4

this is because 11 cannot be divided by 4 exactly so we put it in fraction form .

108° Make me Brainliest pls

Answer:

108 degrees

Step-by-step explanation:

All 4 angles of a quadrilateral added together is always equal to 360 degrees.

252 is the sum of 3 angles

therefore, in order to find the fourth measurment, we subtract 360-252

Answer:

-28

Step-by-step explanation:

f(4) is another notation for x = 4

so we just plug-in 4 for x

f(4) = -4((4)+3)

f(4) = -4(7)

f(4) = -28

The value of f(4) for the function is -28

Function is a type of relation, or rule, that maps one input to specific single output.

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We are given a function as f(x) = - 4(x + 3)

f(4) is another notation for x = 4

Therefore we just plug-in 4 for x

f(x) = - 4(x + 3)

f(4) = -4((4)+3)

f(4) = -4(7)

f(4) = -28

Answer: D

Step-by-step explanation:

(3/8) / (5/9) is the same as multiplying (3/8) by (9/5) which is 27/40. I'm not sure if there's an error between C and D because those are both the same answer since dividing a negative number by a negative number gives you a positive number.

I think C was supposed to be -27/40 so D is the correct answer since it's positive.

X = -10

Y = 8

2 X + 3 Y = 4 ---- (i)

5 X + 4 Y + 13 = 0 ---- (ii)

rearranging eqn (ii), we have

5X + 4Y = -13 ----- (ii)

multiply eqn (i) by 5 and eqn (ii) by 2

10X + 15Y = 20 ---- (iii)

10X + 8Y = -26 ---- (iv)

subtracting eqn (iv) from (iii), we have

10X - 10X + 15Y - 8Y = 20 - (-26)

0 + 7Y = 20 + 26

7Y = 56

Y = 56/7

Y = 8

Substituting Y into eqn (i), we have

2X + 3Y = 4

2X + 3(8) = 4

2X + 24 = 4

2X = 4 - 24

2X = -20

X = -20/2

X = -10

Answer:

The answer is 36 and 28

Step-by-step explanation:

Trust me its correct

pls mark me as brainliest

The addition is one of the four fundamental mathematical operations. The two of the given numbers are 36 and 28.

The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.

Let the sum of two numbers be represented by a and b.

Given that the sum of the two numbers is 64. Therefore, we can write,

a + b = 64

Also, it is given that the difference between the two numbers is 8, therefore, we can write,

a - b = 8

Adding the two of the equation formed together, then,

a + b + a - b = 64 + 8

2a = 72

a = 72/2

a = 36

Substitute the value of a in any one of the two equations,

a + b = 64

36 + b= 64

b = 64 - 36

b = 28

Hence, the two of the given numbers are 36 and 28.

The rule for the transformations would produce an image will be;

''A reflection over the y- axis''

A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.

Given that;

A triangle has vertices at A (-3,-1), B (-6, -5), C(-1,-4) transformations would produce an image with vertices A' (3,-1), B' (6,-5), C' (1, -4)

Now,

We know that;

The rule for the transformation over y - axis will be;

⇒ (x, y) → (- x, y)

Answer:

A,D

Step-by-step explanation:

The requried, expression for the translation of trapezoid ABCD to A'B'C'D' is (x, y) ⇒ (x - 3, y +1). Options A and D both are correct.

Transform the shapes on a coordinate plane by rotating, reflecting, or translating them. Felix Klein introduced transformational geometry, a fresh viewpoint on geometry, in the 19th century.

Here,
Consider trapezoid ABCD,

As we can see the trapezoid is translated 3 units to the left and one unit up,

So the expression of the given translation is given as,
(x, y) ⇒ (x - 3, y +1)

To for the trapezoid A'B'C'D'.

Thus, the requried, expression for the translation of trapezoid ABCD to A'B'C'D' is (x, y) ⇒ (x - 3, y +1). Options A and D both are correct.
