A children clothing manufacturer has 500 yards of material to make shirts and skirts. A shirt requires 0.5 yards of fabric, and a skirt requires 1 yard of fabric. It takes 1 hour to make a shirt and 1.5 hours to make a skirt. The manufacture has 800 hours available to make shirts and skirts.
Answer:
C) x ≥ 0 and y ≥ 0
0.5x + y ≤ 500
x + 1.5y ≤ 800
Step-by-step explanation:
A children clothing manufacturer has 500 yards of material to make shirts and skirts. A shirt requires 0.5 yards of fabric, and a skirt requires 1 yard of fabric. It takes 1 hour to make a shirt and 1.5 hours to make a skirt. The manufacture has 800 hours available to make shirts and skirts.
Which system of inequalities represent the constraints for this situation? Let x = number of shirts, and let y = number of skirts.
A) x ≤ 0 and y ≤ 0
0.5x + y ≤ 800
x + 1.5y ≤ 500
B) x ≤ 0 and y ≤ 0
0.5x + y ≥ 800
x + 1.5y ≥ 500
C) x ≥ 0 and y ≥ 0
0.5x + y ≤ 500
x + 1.5y ≤ 800
D) x ≥ 0 and y ≥ 0
0.5x + y ≥ 500
x + 1.5y ≥ 800
number of shirts,x and number of skirts,y must be greater than 0 since it can not be a negative value
x ≥ 0 ; y ≥ 0
Inequality for number of yards
x = 0.5 yards ; y = 1 yard
Total yards = 500
The inequality is
0.5x + y ≤ 500
Inequality for hours of production
x = 1 hour ; y = 1.5 hours
Total available hours for production = 800
The inequality is
x + 1.5y ≤ 800
Therefore, the system of inequalities which represent the constraints for this situation is
x ≥ 0 ; y ≥ 0
0.5x + y ≤ 500
x + 1.5y ≤ 800
x ≥ 0 and y ≥ 0
0.5x + y ≤ 500
x + 1.5y ≤ 800
When graphed the system shows that the manufacturer should make 200 shirts and 400 skirts for a maximum profit.

Sally found the deal of the century when buying a TV. • The store advertised the TV for 1/3 off. • At the register she handed the cashier a coupon for an additional 1/4 off. If the TV originally cost $320 how much did she pay for it?
Answer:
$160
Step-by-step explanation:
These discounts would be added one after the other. Therefore, we would first apply the first discount of 1/3 to the original price. Since it is a discount it means that from the original price we would pay 2/3. We do this by multiplying this fraction by the original price like so...
$320 * (2/3) = $213.33
Now we add the second discount of 1/4. Again, since it is a discount it means that we would be paying 3/4 of the current price.
$213.33 * 3/4 = $160
Finally, we can see that Sally would have ended up paying $160 for the TV.

Explanation:
The rule for reflecting over y = x is [tex](x,y) \to (y,x)[/tex]
The x and y coordinates swap places.
Point E' is located at (6, -2) so that means point E must be located at (-2, 6)

Graph 8x−4y=16. From Big Ideas Math
Solve for y.
8x−4y=16
-4y = -8x + 16
y = (-8x + 16)/-4
y = (-8x)/-4 + (16/-4)
y = 2x - 4
We only need two points to graph linear equations.
Now let x be 0 and solve for y.
y = 2(0) - 4
y = -4
This leads to the point (0, -4).
We need another point.
Let y = 0 and solve for x.
0 = 2x - 4
4 = 2x
4/2 = x
2 = x
This leads to the point (2,0).
Plot these two points on the xy-plane and connect the points with a straight line.
I'll let you do that.

The scatter plot below shows the number of pizzas sold during weeks when different numbers of coupons were issued. The equation represents the linear model for this data.
y = 3.4x + 43
According to the model, how many pizzas will be sold nightly if 15 coupons are issued?
Enter your answer in the box.
# of pizzas_____
Answer:
94 pizzas will be sold
Step-by-step explanation:
We have to use the equation and replace 15 with x.
x=15
y=3.4x + 43
y=3.4(15) + 43
y=51 + 43
y=94
(15,94)
There will be 94 pizzas sold nightly if 15 coupons were issued.
Answer: To answer this question, substitute the number of tickets sold for the x value.
y = 3.4(15) + 43
Solve the equation by first multiplying the 3.4 and the 15.
3.4 x 15 = 51
This leaves your equation looking like this:
y = 51 + 43
The final step is to add he two integers together.
51 + 43 = 94
So the final answer is y = 94
Therefore, there will be 94 pizzas sold nightly if 15 coupons were issued.
