Answer:

You can say there is no solution for a system of linear equation when the graphs are PARALLEL to each other.

ONE solution: when both lines intersect at one point

INFINITE solution: when the line goes on forever

NO solution: is when the lines are parallel to each other.

Simplify 7(A - 6).<br> A - 6<br> 7A - 42<br> 7A - 6
KIM [24]
So, you already know that you have to multiply the value of 7 by the variable and the number inside of the parentheses. So, 7 x A = 7A, and 7 times -6 equals -42. So, your answer would most likely be 7a - 42.

Answer:

m<E = 77^{o}

Step-by-step explanation:

From the diagram, ΔACE and ΔBDE are similar. So that comparing its angles, we have;

(8x + 4) = (9x - 5)

8x + 4 = 9x - 5

5 + 4 = 9x - 8x

x = 9

Thus,

(8x + 4) = 8(9) + 4 = 76

(9x - 5) = 9(9) - 5 = 76

3x = 3(9) = 27

From ΔACE,

3x + (8x + 4) + m<E = 180 (sum of angles in a triangle)

27 + 76 + m<E = 180

m<E = 180 - 103

m<E = 77^{o}

Factor each expression (6s + 18t + 3w)
Sergeu [11.5K]

Answer:

3(2s + 6t + w)

Step-by-step explanation:

Since the highest GCF is 3, I divided 6s, 18t, and 3w. This equals to 3(2s + 6t + w)

Helllppppppppppp please
sdas [7]

Answer:

h = 5t

Step-by-step explanation:

So basically, its a slope problem again. You are trying to find the equation that equals hits. So you can cross off t = 5h and t = h + 5. So now, you need to find the most reasonable answer by calculating the slope.

If you try h = t + 5,

Put in 3 - you get 8

Put in 7 - you get 12

But on the table you get 15, 36 respectively.

If you try h = 5t,

Put in 3 - you get 15

Put in 7 - you get 35

Which is much closer to the numbers in the table, therefore it is the answer.
