Hey there! Hello!

For this problem, I'm assuming you need help figuring out what quadrants contain which positive and negative plot points, and I can certainly help with that.

I have attached a quick little drawing I did of the different quadrants' labels and their corresponding positive and negative numbers, if that makes any sense. Keep in mind that when you cross the y-axis (the vertical one) from the right to the left side, your x-value will be negative. Same goes for the y-value, except it will be positive on the top and negative on the bottom.

Hope this helped you out! Feel free to ask any additional questions if you have any, or if you still need help figuring out which point on your worksheet goes in which quadrant. :-)

URGENT: I need to solve this problem: 4 - (-6), but that's not all, I'm not really good at math and I need step by step answers

Answer:

3.59

6 7/12

Step-by-step explanation:

4 - (-6)

= 4+ 6 ( because when we multiply the negative sign with the negative sign we get a positive sign or a plus sign)

= 10

-2.5 + 6.1 -10.3 - (-7.79) -4 + 6 1/2

= -2.5 + 6.1 -10.3 +7.79 -4 + 6.5 [ (-*-=+) ( converting 6 1/2 into decimal = 6.5)]

= 6.1+7.79+ 6.5 -2.5 -10.3-4 { adding the + numbers and - numbers separately}

= 20.39 - 16.8 { subtracting the totals of + and - numbers}

= 3.59

8 5/6 + (-2 1/4)

= 53/6 - 9/4 { Converting into improper fractions}

= 53( 2) - 9(3)/12 { Taking LCM = 12}

= 106-27/12

= 79/12

= 6 7/12

{ Converting into improper fractions and vice versa}

we multiply the denominator with the whole number and add it to the numerator to get the improper fraction.( 8 5/6= 53/6)

we divide the numerator with the denominator the answer gives the whole number and the remainder gives the numerator of the proper fraction. ( 79/12 = 6 7/12)

{ Taking LCM = 12}

Factors of 6 are 3 and 2

Factors of 4 are 2 and 2

Least Common Multiple is taking the common factors and multiplying it with the rest . 2 is common in both . It will be taken once and then multiplied with the other 2 and 3 so we get

LCM = 2*2*3= 12

The graph shows a line and two similar triangles.

zhuklara [117]

Answer:

Option C. is the correct option.

Step-by-step explanation:

The given line in the graph passes through two points (0, 3) and (3, 7).

We have to find the equation of the line.

Since y = mx + c is the standard equation of a line

where m = slope of the line

c = y - intercept

Slope of a line m = $\frac{(y-y')}{(x-x')}$

Now we put the values of x and y to find the slope of this line.

m = $\frac{7-3}{3-0}=\frac{4}{3}$

Since (0, 3) passes through the line

3 = 0 + c

c = 3

Equation of the line will be

$y=\frac{4}{3}x+3$

Option C. is the answer.

Cam someone please explain how to do this?

Illusion [34]

When quantities are in a proportional relationship, they are related to each other by a multiplicative constant. That is the case for selections F, G, J, but not the case for selection H.

You are asked to find the relationship that is NOT a proportional relationship. The appropriate choice is ...
H. y = 1/2 + x

6v + 38 = -4 or 2(v + 3) = -2 How do I solve this?

olga_2 [115]

6v + 48 = -4
6v + 48 - 48 = -4 - 48
6v = -52
v = -52/6
