NEED HELP ASAP!!! Which of the following correctly uses absolute value to show the distance between −70 and 15? Question 6 options: 1) |−70 − 15| = |−85| = −85 units 2) |−70 + 15| = |−55| = 55 units 3) |−70 − 15| = |−85| = 85 units 4) |−70 + 15| = |−55| = −55 units

Answers

Answer:

3) |−70 − 15| = |−85| = 85 units

Step-by-step explanation:

Absolute value ignores negative values so the equation when finding the distance between −70 and 15 is 70 + 15 which equals 85.

Which expression is equivalent to 4 to the 9th power and 4 to the 0 power
a. 4 to the 8th power
b. 4 to the 0 power
C. 4 to the 7 power
d. 4 to the 9 power

Answers

Answer:

d. 4^9

Step-by-step explanation:

Question:

Which expression is equivalent to 4^9/4^0?

a. 4^8

b. 4^0

c. 4^7

d. 4^9

Solution:

By definition, a number raised to the 0 power equals 1, with the possible exception of 0^0 which according to some is undefined.

Any number divided by 1 equals the number itself.

For example, 2/1 = 2; 5/1 = 5; -20/2 = -20.

4^0 = 1

Since 4^0 = 1, then when you divide 4^9 by 4^0 you are dividing 4^9 by 1, so you get 4^9.

4^9/4^0 = 4^9/1 = 4^9

Solve for x.

[tex]3x - 5 = \frac{12 + 4x}{2} [/tex]

x = [?]​

Answers

Answer:

x= 11

Step-by-step explanation:

[tex]3x - 5 = \frac{12 + 4x}{2} [/tex]

Multiply both sides by 2:

2(3x -5)= 12 +4x

Expand:

2(3x) +2(-5)= 12 +4x

6x -10= 12 +4x

Bring all x terms to 1 side, constant to the other:

6x -4x= 10 +12

2x= 22

Divide by 2 on both sides:

x= 22 ÷2

x= 11

6x-10=12+4x
6x-4x=12+10
2x=22
X=11

What is the equation of the graph shown?​

Answers

Greetings from Brasil...

As we have a line, the function will be given by the expression:

F(X) = AX + B

where

A = ΔY/ΔX

B = where the line intersects the Y axis

Looking at the graph we have already concluded that

B = - 3

A = ΔY/ΔX

A = (5 - 3)/(4 - 3)     see attached picture

A = 2

So,

F(X) = AX + B

F(X) = 2X - 3

What is the measure of the smallest angle in the figure? The figure is not drawn to scale. ​

Answers

Answer:

(4x-3)°=37

Step-by-step explanation:

solve for x

6x-7+90+4x-3=180

10x=180-80

10x= 100

x=10°

from the equations;

4x-3= 4(10)-3=37° and

What is quadrilateral?

A closed quadrilateral is a form of polygon with four sides, four vertices, and four angles. Four non-collinear points are joined to create it. Quadrilaterals' internal angles add up to a constant 360 degrees.

In the given quadrilateral,

Side AD = 8X - 1, CD = 6X + 9

And  AB = 3x - 2

According to given diagram,

AD = CD

8x -1 = 6x + 9

2x = 9 + 1

2x = 10

x = 5

The length of side AB = 3x - 2 = 3 (5) - 2 = 15 - 2 = 13

The figure ABCD is a symmetrical figure,

Therefore,

AB = BC

AB = BC = 13

The required side AC = AB + BC

= 13 + 13

= 26

The length of the side AC is 26 units.

Step-by-step explanation:

For Before A, I multiplied both denominator and numerator by square root of 3. The multiplication moved the square root to the numerator, simplifying the fraction.

The different forms of B and C are just that I multiplied the square of the first number into the square roots. This is OK because the square root of a number's square is the number itself. Therefore, you can multiply a square root by the square of the number from outside the root.
