Answer:
a = 1
Step-by-step explanation:
Given the point (a, 3) is on the line: 5x + y = 8.
Any point on the line satisfies the equation.
So, (a, 3) should satisfy the equation 5x + y = 8
Substituting x = a and y = 3, we get:
5(a) + 3 = 8

⇒ a = 1
Therefore, (1, 3) is the point on the line.
A system of equations has no solution. if y = 8x+ 7 is one of the equations, The other equation will be y = 8x - 7.
<h3 /><h3>What is the system of two equations?</h3>
A set of two linear equations with two variables is called a system of linear equations. They create a system of linear equations when evaluated collectively.
The first equation is given as:
y = 8x + 7
The equations in the system would have different constant values if the system of equations had no solution.
y=8x+b
Where:
b is a variable that is not equal to 7.
The equation whose standard form is y=ax+b has no solution. Only equation 2 satisfies the generalized form.
Hence.if y = 8x+ 7 is one of the equations, The other equation will be y = 8x - 7.

Answer:
Step-by-step explanation:
The total of all 3 angles in every triangle equals 180 degrees. An isosceles triangle has two side lengths equal and two angle degrees equal.
So you either have two angles with each having 70 degrees and the third angle is 40 degrees,
70 + 70 + 40=180
OR
One angle of 70 degrees and two angles that are 55 degrees each.
70 + 55 +55 =180
