Value=amount times cost per unit
paper=10 times 0.55
pencils=6 times 0.75
she bought 10 paper and 6 pencils
cost=10*0.55+6*0.75=$10.00 total
Answer:
y=-2x+2
slope-intercept form --> y=mx+b
m= slope. the slope in the graph is down 2 over 1, -2/1 which is the same as -2.
b = <u>y-intercept</u><u>. </u><u> </u><u>the </u><u>y-intercept</u><u> </u><u>is </u><u>2</u><u>.</u>

Answer: −(b+4)(2b−3)
Step-by-step explanation:
1. Factor out the negative sign.
−(2b^2+5b−12)
2. Split the second term in 2b^2+5b−12 into two terms.
−(2b^2+8b−3b−12)
3.Factor out common terms in the first two terms, then in the last two terms.
−(2b(b+4)−3(b+4))
4. Factor out the common term b+4b+4b+4.
−(b+4)(2b−3)
Answer:
b) ? = 0
c) ? = 10
Step-by-step explanation:
By observing the equations, we notice a pattern. The resulting number is always equal to one number doubled added to the other number. Therefore, set up two equations as follows:
2(7)+y=14
2x+3=23
Assume that the provided number is the doubled number if it is a perfect factor, with 2, and assume the provided number is not the provided number if the difference between the answer and it is an even number.
Solve:
14+y=14
y=0
2x+3=23
2x=20
x=10
