Which linear function is graphed on the grid?
a - g(x) = 2/15x - 6
b - g(x) = 2/15x + 45
c - g(x) = 15/2x - 6
d - g(x) = 15/2x + 45

Answers

Answer:

G(x)=2/15x-6

Step-by-step explanation:

The linear function graphed on the grid will be g(x) = (15/2) x + 45. Then the correct option is D.

What is a linear equation?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

x/a + y/b = 1

Where 'a' is the x-intercept of the line and ‘b’ is the y-intercept of the line.

From the graph, the x-intercept is - 6, and the y-intercept is 45. Then the equation is given as,

x/(-6) + y/45 = 1

- 15x + 2y = 90

y = (15/2) x + 45

g(x) = (15/2) x + 45

The linear function graphed on the grid will be g(x) = (15/2) x + 45. Then the correct option is D.

Answer:

31536000 seconds

Step-by-step explanation:

The asnwer is 31536000 seconds.

Mark wants to round to the nearest hundred to estimate the sum of 271 and 582.
He wrote 270 + 580 = 850.

Part A
What mistake did Mark make?
A.
00:00



Mark should have rounded 271 to 250 and rounded 582 to 550: 250 + 550 = 800.
B.
00:00



Mark should have rounded 271 to 250 and rounded 582 to 600: 250 + 600 = 850.
C.
00:00



Mark should have rounded 271 to 300 and rounded 582 to 500: 300 + 500 = 800.
D.
00:00



Mark should have rounded 271 to 300 and rounded 582 to 600: 300 + 600 = 900.
00:00

Part B
What is the sum of 271 and 582 rounded to the nearest hundred?
A. 300
B. 850
C. 900
D. 1,000

Answers

Answer:

Step-by-step explanation:

Part A:

Mark did not round to the nearest hundreds, he rounded to the nearest tens.

Option A (Incorrect):

271 and 582 are normally not rounded down, unless we are using limits coming from the left and a unique equation.

Option B (Incorrect):

271 as the same problem as option A, but 582 rounding to 600 is correct. It doesn't make sense to round both numbers differently, unless stated.

Option C (Incorrect):

271 rounding to 300 is correct, but 582 is not normally rounded down to 500 unless we are using limits coming from the left and a unique equation. Unless stated, don't round both numbers differently.

Option D (Correct):

271 rounded to 300 and 582 rounded to 600 looks correct for rounding to the hundreds.

Part B:

There are two ways to solve this question:

One way:

271 + 582 = 853

Round 853 to the nearest hundred for 900

(Note: Round 853 to the nearest tens for 850.)

Second way:

271 + 582

Round Numbers:

300 + 600

= 900

A regular 13-gon is inscribed in a circle. Find the measure of each are intercepted by the sides of the polygon. Round your answer to the nearest hundreth of a degree.

Answers

Answer:

The measure of the angle subtended by each arc intercepted by the sides of the reh13-gon is approximately 27.69°

Step-by-step explanation:

The number of of equal sides in a regular 13-gon = 13 sides

The measure of the angle, 'θ', subtended by each arc intercepted by the sides of the 13-gon is given as follows;

θ = 360°/13 = [tex]27\dfrac{9}{13} ^{\circ}[/tex]  

By rounding rounding the answer to the nearest 10th, we have that the measure of the angle subtended by each arc intercepted by the sides of the 13-gon, θ = [tex]27\dfrac{9}{13} ^{\circ}[/tex] ≈ 27.69°

Examine the system of equations. Which is an equivalent form of the first equation that when added to the second equation eliminates the y terms? Negative StartFraction 5 Over 8 EndFraction x + three-fourths y = 12 8 x + 12 y = 11

Answers

Answer:

10x - 12y = 192

Step-by-step explanation:

Given the equation :

-5/8x + 3/4y = 12 - - - (1)

8x + 12y = 11 ___(2)

The equivalent form of the first equation which can eliminate the y term :

Multiply (1) by - 16 :

-5/8x * - 16 + 3/4y * - 16 = 12 * - 16

10x - 12y = 192

Hence, Adding the obtained equation and equation(2) will eliminate.

Which ratio is smaller, 32 : 24 or 30 : 22?​

Answers

Answer:

32 : 24 is smaller

Step-by-step explanation:

32 : 24 = 32/56, reduced is 4/7

30 : 22 = 30/52, reduced is 15/26

a common denominator is 182:

4/7 = 104/182

15/26 = 105/182

32:24 -> 30:22

You need to get one number from each ratio to be equal

I’m gonna get 32 and 30 to equal

*first divide both ratios by 2(don’t have to do this just makes the no.’s smaller)
32:24
16:12

30:22
15:11

Multiply 16:12 by 15
And multiply 15:11 by 16

32:24 -> 16:12 -> 240:180
30:22 -> 15:11 -> 240:176

176<180
Therefore ratio 30:22 is smaller
