PLS HELP IVE BEEN ASKING FOR 4 HOURS NOT A SINGLE PERSON HAS BEEN RIGHT ITS PAST DUE :( JUST TROLLS I WILL GIVE BRAINLIEST JUST PLS HELP

The upper and lower bounds for the numbers are illustrations of approximation

The numbers are given as:

a = 6.54 (to 3 significant figures)

b = 123 (to 3 significant figures)

(a) a + b

We have:

a + b = 6.54 + 123

a + b = 129.54

When approximated, the bounds to three significant digits are:

Lower bound = 129

Upper bound = 130.1

(b) ab

We have:

ab = 6.54 * 123

a + b = 804.42

When approximated, the bounds to three significant digits are:

Lower bound = 804

Upper bound = 805

(c) a/b

We have:

a/b = 6.54/123

a/b = 0.0531707317

When approximated, the bounds to three significant digits are:

Lower bound = 0.0531

Upper bound = 0.0532

(d) b - 1/a

We have:

b - 1/a = 123 - 1/6.54

b - 1/a = 122.847094801

When approximated, the bounds to three significant digits are:

Lower bound = 122

Upper bound = 123

Answer:

the answer: 56.25 percent of 80

Plug (0,-5) into the equation -

-5 = -5(0)

-5 times 0 is 0

-5 = 0

(0,-5) is NOT a solution to the equation.

Good luck!

Answer:

No, it is not the solution to the equation.

Step-by-step explanation:

(0, -5)

y = -5x

So we have to plug in the values for x and y. 0 is our x value and -5 is our y value.

-5 = -5(0)

-5 = 0

Therefore, (0, -5) is not a solution to the equation

Step-by-step explanation:

other statements are false

Answer:

Option A is your definite answer.

Step-by-step explanation:

We know that the x coordinate is positive since it is on the positive half of the x-axis. We also can identify that the point A is in the 4th Quarter of the grid, so the y coordinate is negative.

The only choice that proves this reasoning true is option A :)

Answer:

y = -1/5x - 10

Step-by-step explanation:

Pick any two points on the line.

(0,-10) and (50,-20)

find the slope by using m = y2-y1/x2 - x1(rise over run)

m = -20-(-10) / 50 - 0

m = -10/50 = -1/5 -- this is your slope

slope intercept form is y = mx + b, but we need to find your b, which is your y intercept. you find this by asking yourself, what is the y coordinate when x = 0? It is -10.

so now you have all the points you need.

y = mx + b

y = -1/5x - 10

$3063.6

Step-by-step explanation:

The formula for finding percents is number x percent ÷ 100.

4,255 x 72 ÷  100 = 3063.6

Answer:

x = 1 , x = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

2x² - 5x + 3 = 0

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 2 × 3 = 6 and sum = - 5

The factors are - 2 and - 3

Use these factors to split the x- term

2x² - 2x - 3x + 3 ( factor the first/second and third/fourth terms )

2x(x - 1) - 3(x - 1) = 0 ← factor out (x - 1) from each term

(x - 1)(2x - 3) = 0

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

2x - 3 = 0 ⇒ 2x = 3 ⇒ x = [tex]\frac{3}{2}[/tex]

Answer:

-48

Step-by-step explanation:

−112÷2 1/3 needs to be rewritten as -112 / (7/3), where 7/3 is the improper fraction version of 2 1/3.

Then we have

 -112

---------

  7/3

Recall that division by a fraction is equivalent to multiplication by the reciprocal of the fraction; thus, the above expression becomes

-112 * 3

-----------

     7

This, in turn, can be reduced through division to -16*3, which equals -48.

Step-by-step explanation:

To make it easier to understand, consider the exponent of a number with no decimals, with 1 decimal and with 2 decimals:

Since our given number is (0.23)⁹, with 2 decimal places, its exponent will have 2*9 = 18 decimals.

Answer:

Step-by-step explanation:

7(0)+y=10

y=10

Answer: (0, 10)

Step-by-step explanation:

The given expression is in the standard form of linear equations: Ax + By = C, where A and B are constants.

The definition of y-intercept is the point that intersects with the y-axis, meaning that the [x] value of the point will be zero.

To find the y-intercept of an equation, substitute the [x] variable with 0, as mentioned above, the [x] value of a y-intercept is 0.

[tex]7x+y=10\\[/tex]

[tex]7(0)+y=10[/tex]

[tex]0+y=10[/tex]

[tex]y=10[/tex]

As we find the [y] value is 10, while the given [x] value is 0, therefore, the y-intercept of [tex]7x+y=10[/tex] is [tex]\boxed{(0,10)}[/tex].

Answer:

x = 25

Step-by-step explanation:

Internal angles of a triangle = 180 degrees

So knowing this we can form the following equation

(x + 26) + (x + 14) + (4x - 10) = 180

Simplify

(x + x + 4x) + (26 + 14 - 10) = 180

6x + 30 = 180

Rearrange for x

6x = 180 - 30

6x = 150

x = 25
