Step-by-step explanation:
Im not for sure though on the last 2
Answer:
Step-by-step explanation:
Let's convert this statement into a system of two equations
3 * (cost of a liter of milk) + 5 * (cost of a loaf of bread) = $11
4 * (cost of a liter of milk) + 5 * (cost of a loaf of bread) = $10
cost of a liter of milk = x
cost of a loaf of bread = y
3x + 5y = 11
4x + 4y = 10
You can now solve this using either substitution or elimination
I'll use elimination. Let's say I want to get rid of the x first. I need to choose numbers to multiply by the top and bottom equations to eliminat the x's. The easiest way to do this is to multiply them by each other. So we'll multiply the top by 4 and the bottom by 3. We'll need to make sure the signs are opposite as well so I'll make that a negative 3 on the bottom.
4 * (3x + 5y = 11)
-3 * (4x + 4y = 10)
12x + 20y = 44
-12x - 12y = -30
Now add straight down
0x + 8y = 14
8y = 14
y = 14/8 = $1.75
Now we can plug this back in to either equation to find the x. I'll choose the second equation
4x + 4*(1.75) = 10
4x + 7 = 10
4x = 3
x = 3/4 = $0.75
So, cost of a liter of milk = x = $0.75
and cost of a loaf of bread = y = $1.75
Answer:
81 + 6 + 1 = 88 if that's your question
Step-by-step explanation:
The function h(x) is vertically stretched by a factor of 
and is shifted 3 units to the left and shifted 2 units up.
Explanation:
The parent function is 
The translated function is 
By using the function transformation rules, the translated function h(x) is stretched vertically by a factor of
Also, from the function transformation rules, we know that, 
shifts the function b units to the left.
Thus, the translated function h(x) is shifted 3 units to the left.
By using the function transformation rules, we know that, 
shifts the function b units upward.
Thus, the translated function h(x) is shifted 2 units upwards.
Thus, the translated function h(x) is vertically stretched by a factor of and is shifted 3 units to the left and shifted 2 units up.
