Answer:
C. (-2, 1)
Step-by-step explanation:
See the attached graph.
The slope of the first line is -1, and its y-intercept is -1.
The slope of the second line is +1 and its y-intercept is +3.
The solution is the point that is common to both lines, (-2, 1).
X = 34
<span>2+8-x=-24
</span>Add 2 + 8: 10-x=-24
Subtract 10 from each side: -x = -34
Change the signs from each side: x = 34
I’m pretty sure the value is 80 because that’s a 90° angle. 90 minus that 10 leaves 80
Answer:
D. 3b + 2(b + 0.75) = 4.50; $0.60 per pound of bananas, $1.35 per pound of oranges
Step-by-step explanation:
Price per pounds of bananas = b
Price per pound of oranges = b + $0.75
Diego buys:
3 pounds of bananas = 3(b) = 3b
2 pounds of oranges = 2(b + 0.75)
Amount paid by Diego is expressed as:
3b + 2(b + 0.75) = 4.50
To find the price per pound of each fruit, use the equation above to find the value of b:
3b + 2b + 1.50 = 4.50
Combine like terms
5b + 1.50 = 4.50
5b + 1.50 - 1.50 = 4.50 - 1.50
5b = 3
5b/5 = 3/5
b = 0.6
Price per pound of banana = b = $0.6
Price per pound of oranges = b + $0.75
Plug in the value of b
= $0.6 + $0.75
= $1.35
