Answer:
4 + 12 × 19 + 24
Step-by-step explanation:
Hullo!
Words like "added or sum", represent addition.
Words like "times", represent multiplication.
Words like "subtracted or took away", represent subtraction.
Words like "divided or split up", represent division.
Therefore, we can express the equation 4 added to 12 times 19 plus 24 can be rewritten as in expression format.
Hope this helps!
Answer:
The system of linear equations has infinitely many solutions
Step-by-step explanation:
Let's modified the equations and find the answer.
Using the first equation:
we can multiply by 2 in both sides, obtaining:
which can by simplified as:
which is equal to:
Considering the second equation:
Taking into account that from the first equation we know that: , we can express the second equation as:
, which can be simplified as:
Because (-8) is being divided by (2+k), then (2+k) can't be equal to 0, so:
if
This means that k can be any number different than -2, and for each of these solutions, there is a different solution for y, allowing also, different solutions for x.
For example, if k=0 then
which give us y=-4, and, because:
if y=-4 then
Now let's try with k=-1, then:
which give us y=-8, and, because:
if y=-8 then
.
Then, the system of linear equations has infinitely many solutions
