Answer:
Problem:
Solve x+y=7;x+2y=11
Steps:
I will try to solve your system of equations.
x+y=7;x+2y=11
Step: Solvex+y=7for x:
x+y+−y=7+−y(Add -y to both sides)
x=−y+7
Step: Substitute−y+7forxinx+2y=11:
x+2y=11
−y+7+2y=11
y+7=11(Simplify both sides of the equation)
y+7+−7=11+−7(Add -7 to both sides)
y=4
Step: Substitute4foryinx=−y+7:
x=−y+7
x=−4+7
x=3(Simplify both sides of the equation)
Answer:
x=3 and y=4
Step-by-step explanation:
3. mid point
4. vertically opposite angles
5. SSA rule
6. alternate angles
8. midpoint p
9. AP/AB = 1/2 = PQ/BC
The sum of the angles in a triangle is 180°, so the angles do form a triangle. Since two of the three angles are congruent, the triangle is an isosceles triangle. An infinite number of isosceles triangles exist with different side lengths.
Therefore, more than one triangle exists with the given angle measures.
The slope in this equation is -1500. It is telling us that every time x is a positive number, the answer for other term gets smaller and vice versa.
