Let
x = loaves of bread
y = batches of muffins
You must make a system of two equations with two unknowns that describe the problem
3.5x + 2.5y = 17 --- (1)
0.75x + 0.75y = 4.5 --- (2)
Resolving we have
x = 6-y (from (2))
replacing in (1)
3.5 (6-y) + 2.5y = 17
21 - 3.5y + 2.5y = 17
y = 21-17 = 4
Then substituting in (2)
x = 6-y = 6-4 = 2
Answer
Helena could bake:
2 loaves of bread
4 batches of muffins
Hi,
Let's simplify this equation step-by-step.
7−2(5−2x)−10x+25−4x−3
Distribute:
=7+(−2)(5)+(−2)(−2x)+−10x+25+−4x+−3
=7+−10+4x+−10x+25+−4x+−3
Combine Like Terms:
=7+−10+4x+−10x+25+−4x+−3
=(4x+−10x+−4x)+(7+−10+25+−3)
=−10x+19
Answer:
=−10x+19
Have a great day!
I can’t really see it well

f(x) = (x - 4)^2 - 5
Vertex (4 , -5)
This function opens upward and has min. value = -5
So range y >= - 5
So answer is A. -5 <= f(x) < ∞
