Step 1: Y is equal to 
so where ever you see a y in the equation 3x - 4y = -5 replace it with
3x - 4() = -5
Now all your variables are x and you can solve for x
Step 2: Distribute for to the numbers in the parentheses
3x - 3x - 8 = -5
Step 3: Combine like terms
0x - 8 = -5
0x = 3
Step 4: Isolate x
0x/0 = 3/0
3/0 is undefined
^^^ This means that there is no answer
If you look at the graph below you can see that these lines are parallel and therefore have no intersection point
Hope this helped!
Answer:
Use by Prime factorisation method
If there is 8 ice cream sandwiched with 2 pints in each just multiply and it's 16 pints. A strategy you can use is the count on strategy for example -
2,4,6,8,10,12,14,16
The required additional information required to prove the Triangles congruent are :
The Triangles will be congruent by HL congruency.
The Triangles are congruent by LL congruency.
The Triangles are congruent by HA congruency.
The Triangles are congruent by LA congruency.
Answer:
Step-by-step explanation:
a). By applying Pythagoras theorem in right triangle ABC,
AC² = AB² + BC²
20² = 16² + BC²
BC = 
= 12
Therefore, another leg of the triangular base = 12 cm
Area of the triangular base ABC = 
= 
= 96 cm²
Volume of a triangular prism = Area of the triangular base × height
960 = 96 × b
b = 10 cm
b). Area of the triangle ABC = 96 cm²
