Answer:
there's no solution.
Step-by-step explanation:
if y = 3x -4 then use this instead of y in the second equation
9x -3(3x+4) = 14 ➡9x-9x -12 = 14 9x will eliminate -9x and -12 can't be = 14 so there's no solution
Answer:
or
Step-by-step explanation:
we have
This is a vertical parabola open upward (because the leading coefficient is positive)
The vertex is a minimum
Convert to vertex form
Factor the leading coefficient
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
----> equation in vertex form
or
The vertex is the point (0.25,10.5)
Answer:
Ok I’ll give a simple equation that your teacher probably won’t accept and one that your teacher will accept
Teacher accept: x-45=122
Not accept but way easier: 122+45=x
ALSO The answer to x: 167
Step-by-step explanation:
Heres the loop hole, they asked for 2 sentences but never declared the length of each sentence.
Explanation:
So we know that grace lost 45 pounds and at the end she weighs 122.
We don’t now what the beginning weight so we can make an equation like x-45=122 where x represents her before weight and the subtract 45 is when she lost that much and the final results of 122, if solved You’ll get her begginisng weight, 167.
Answer:
36
Step-by-step explanation:
–12i × 3i
Multiply the numbers
-12*3 = -36
Multiply the imaginary number
i*i= i^2
We know i^2 = -1
-36 * -1 = 36
$300 because 300x2=600 then 75x8=300 and 600+300=900
