Totalcost=ridescost+admissioncost
ridescost=numberofrides times cost per ride
ridescost=25*1.25=31.25
totalcost=43.75
43.75=31.25+admission
minus 31.25 both sides
12.5=admision
a.
y=1.25x+12.5
b. y is cost and x is number of tickets purchsed
c. math
Answer:
-y/7 = 24
-y = 24(7)
-y = 168
y = -168
Step-by-step explanation:
Answer:
−2.5d−0.7
Step-by-step explanation:
1 Expand by distributing terms.
-(2.5d+5)+4.3
2 Remove parentheses.
-2.5d-5+4.3
3 Collect like terms.
-2.5d+(-5+4.3)
4 Simplify.
-2.5d-0.7
We know that
If the scalar product of two vectors<span> is zero, both vectors are </span><span>orthogonal
</span><span>A. (-2,5)
</span>(-2,5)*(1,5)-------> -2*1+5*5=23-----------> <span>are not orthogonal
</span><span>B. (10,-2)
</span>(10,-2)*(1,5)-------> 10*1-2*5=0-----------> are orthogonal
<span>C. (-1,-5)
</span>(-1,-5)*(1,5)-------> -1*1-5*5=-26-----------> are not orthogonal
<span>D. (-5,1)
</span>(-5,1)*(1,5)-------> -5*1+1*5=0-----------> are orthogonal
the answer is
B. (10,-2) and D. (-5,1) are orthogonal to (1,5)
