Answer:

A. x=4

Step-by-step explanation:

The y-axis is a vertical line at x=0, so for a line to be parallel to x=0, x must equal another constant. Option A is the only option that has a constant.

Answer:

Step-by-step explanation:

So for question 1, we can see that we have a 30 60 90 triangle with a hypotenuse of 9.

So therefore, y=9/2 and x=4.5sqrt3.

Answer:

you move the decimal 2 spaces

Step-by-step explanation:

So, the decimal is at the end of a number right? You move the end decimal two spaces to the right.

Example: make 2 into a percentage

2.00

----->two spaces

So, 2 = 200%

HOPE THIS HELPS

Answer:

Really simple!

All you have to do is take the decimal form of the number and multiply it by 100 and then add the percent sign

Step-by-step explanation:

Example 1: 10

Decimal form: 0.10

Convert it into a percent: 0.10 * 100 =10%

Example 2: 67.5

Decimal Point: 0.675

Convert it into a percent: 0.675 * 100 =67.5%

The graph of the function f(x) = x³ – 2x² – 19x + 20 passes through the  x-axis at  –4, 1, and 5.

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The function is given as

f(x) = x³ – 2x² – 19x + 20

By hit and trial. Let x = 1, we have

f(x) = 1³ – 2(1)² – 19(1) + 20 = 0

Then the equation will be

f(x) = (x – 1)(x² – x – 20)

f(x) = (x – 1)(x – 5)(x + 4)

Then the graph of the function passes through x-axis at  –4, 1, and 5.

The graph is shown below.

Step-by-step explanation:

(a) The interior angles of any triangle sum to 180° in measure. So

(8x + 2) + 70 + 60 = 180

Solve for x :

8x + 132 = 180

8x = 48

x = 6

(b) Evaluate 8x + 2 when x = 6 :

8•6 + 2 = 48 + 2 = 50

Answer:

the answer is log3 (2x+8)=log3 x²

Step-by-step explanation:

log3(2x^4+8x^3)-3log3x=2log3x

simplifying the above we get:

log3(2x^4+8x^3)=2log3x+3log3x

log3(2x^4+8x^3)=5log2x

Hence the answer should be:

log3 (x³)*(log3(2x+8))=5log3 x

3log3 x+log3(2x+8)=5log3 x

log3(2x+8)=5log3 x-3log3 x

log3 (2x+8)=2log3 x

log3 (2x+8)=log3 x²

Rounding off is basically a approximate value written in compact form for our convenience when precise  accurate result is not that necessary.

A decimal is a point or a dot separating the whole part and the fractional part of the number.Now rounding off numbers to certain decimal places has a condition if the digits just after the decimal is more than half we take the upper value if itis less than half we take the lower value.

Given in this question let's go by rounding off from 1 place to 4 for better understanding.

rounding off 24513589 to one decimal place = 2451359.0

rounding off 2451359.0 to one decimal place = 245136.0

rounding off 245136.0 to one decimal place = 24514.0

rounding off 24514.0 to one decimal place  = 2451.0

Answer:

24 degrees

Step-by-step explanation:

total degrees in a triangle is equal to 180 degrees.

180 - 132 = 48

since there are two unknown angles, we have 48 by 2 which is 24.

48/2=24 degrees

Answer:

[tex]\huge\boxed{\sf{x=24}}[/tex]

Step-by-step explanation:

Hello.

The sum of all three angles in a triangle = 180 degrees

Now, what is the value of x?

The 2 sides of the triangle are equal, thus, the angles are equal.

Write the equation

x+x+132=180

Combine like terms

2x+132=180

Subtract 132 from both sides

2x+132-132=180-132

2x=180-132

2x=48

Divide both sides by 2

x=24

Answer:

f(x) = 2x+5

Step-by-step explanation:

As you know, a student ticket is one item, and you only need one of these to enter a football game. We will assume he is by himself and without friends. There are items he can buy for $2 each at the concession stand.

With what we know, we can conclude that the total cost to attend the football game could be a function.

The function will be

f(x) = 2x + 5

This is because you buy the ticket one time and buys x items, which is modeled by the function.

Answer:

y = (9/4)x + 2, given that I've assume the correct meaning of "-5x4."

Step-by-step explanation:

A parallel line has the same slope as the reference line,

The reference line is 9x-4y = -5x4, as written.  I'm not sure the 4 belongs, but I'll assume it is written correctly.  I'm not sure if the term -5x4 is meant to mean -5x^4, -20x or -20.  I'll assume -20:

9x-4y = -20

Put the equation into standard slope-intercept form:  Y = mx + b, where m is the slope and b is the y-intercept (the value of y when  x = 0).

-4y = -9x - 20

y = (9/4)x + 5

This line has a slope of (9/4).  The parallel line will have the same slope.

y = (9/4)x + b

We can find a value of b that would shift this line to include (4,7) by using this point in the equation:

y = (9/4)x + b

7 = (9/4)(4) + b

7  = 9 + b

b = 2

The equation of a line parallel to the reference line is y = (9/4)x + 2

6x² +9x +3  , divide all terms by 6 to have the first term with coefficient 1

x² + (9/6)x + (3/6) , simplify the fractions

The value of c that makes the equation true is: c = -13/21.

An equation is a mathematical statement whose values on the right and left sides are equal.

Given:

c + 15 = 23c + 2 − 43c

Find the value of c

c + 15 = -20c + 2

c + 20c = -15 + 2

21c = -13

c = -13/21

Thus, the value of c that makes the equation true is: c = -13/21.

The value of c which makes the equation c + 15 = 23c + 2 − 43c true is –13/21

c + 15 = 23c + 2 − 43c

The value of c in the expression above can be obtained as illustrated below:

c + 15 = 23c + 2 − 43c

Collect like terms

c – 23c + 43c = 2 − 15

21c = –13

Divide both side by 21

c = –13/21

Thus, from the calculation made above, we can conclude that the value of c which makes the equation true is –13/21
