10x + 3y = 19
y = 2x + 5
Putting y in the first equation
10x + 3.(2x + 5) = 19
10x + 6x + 15 = 19
16x = 19 - 15
16x = 4
x = 4/16
x = 1/4
Now x in y
y = 2x + 5
y = 2.1/4 + 5
y = 2/4 + 5
y = 1/2 + 5
y = 11/2
Answer:
B. The second choice.
Step-by-step explanation:
A function cannot have two points with the same x-coordinate.
If you graph two different points that have the same x-coordinate, they will both lie on the same vertical line. Therefore, if in a relation, more than one point lie on the same vertical line, then the relation is not a function.
Answer:
500 Grams
Step-by-step explanation:
40 x 5 = 200 = $2
100 x 5 = 500

<h3>What do you mean by
energy?</h3>
Energy, which is observable in the execution of labour as well as in the form of heat and light, is the quantitative quality that is transferred to a body or to a physical system in physics. Energy is a preserved resource; according to the rule of conservation of energy, energy can only be transformed from one form to another and cannot be created or destroyed. The joule (J) is the SI's (International System of Units) unit of measurement for energy. "The energy imparted to an object by the work of moving it a distance of one metre against a force of one newton" is how it is defined.

Answer:
45 degrees
Step-by-step explanation:
If KL = MN, and LM =3 and KN = 13, then HN = 13 - (13-3)/2 = 8
LN = sqrt(HN^2 + LH^2) -->
LN = sqrt89 sqrt(8^2 + LH^2) -->
89 = 64 + LH ^2 -->
25 = LH^2 -->
LH = 5
Because HN = 8, HK = 13 - 8 = 5
That makes both legs equal, which makes m∠LKN = 45 degrees
