Step: Solvey=2x+6for y:
y=2x+6
Step: Substitute2x+6foryin3y=x−2:
3y=x−2
3(2x+6)=x−2
6x+18=x−2(Simplify both sides of the equation)
6x+18+−x=x−2+−x(Add -x to both sides)
5x+18=−2
5x+18+−18=−2+−18(Add -18 to both sides)
5x=−20
5x/5=−20/5
(Divide both sides by 5)
x=−4
Step: Substitute−4forxiny=2x+6:
y=2x+6
y=(2)(−4)+6
y=−2(Simplify both sides of the equation)
Answer:
x=−4 and y=−2

Clare cycled a total of 6.48 kilometers by making 4 trips to work. How many trips will Clare have to make to cycle a total of 8.1 kilometers?
Answer:
5 trips
Step-by-step explanation:
6.48 km = 4 trips
1 trip = 6.48km ÷ 4 trips
1.62km = 1trip
8.1 kilometers ÷ 1 trip = 8.1 kilometers ÷ 1.62km
8.1 kilometers = 5 trips
∴ 8.1kilometers covers 5 trips

the sum of two numbers is 16. their difference is 1. what is the product of the two numbers
Answer:
The product of the numbers is 63.75
Step-by-step explanation:
Let the numbers be x and y
x + y = 16
x -y = 1
Adding both together
2x = 17
x = 17/2
x = 8.5
Recall
x -y = 1
8.5 - y = 1
y = 8.5 - 1 = 7.5
Their product is xy
so we have 7.5 * 8.5 = 63.75
Is this relation a function?Explain
Answer:
Yes it's a function

$25 with a 300% increase
Answer:
100 dollars
Step-by-step explanation:
So amount of increase = (300/100) * 25
= 3 * 25
= 75 dollars
Then the final amount = (25 + 75) dollars
= 100 dollars

Pls help me fast this is important
Answer:
C
Step-by-step explanation:
the slope is -1/3 and y-intercept is 2
Answer:
C. y = - 1/3 x + 2
Step-by-step explanation:
the y intercept is where y is when x = 0 in other words, the number on the y line
the slope is m = 1-2 = -1
3-0. 3
so when you insert that into your slope equation y =mx+b you get y = -1/3 x + 2

"I am 3 times as old as Sue is," Frank said to Ann. "On the other hand, I am 15 years older than John while Sue is 1 year younger than John. How old am I?"
If J represents John's age, then which of the following equations could be used to solve the problem?
J + 15 = 3J - 1
3(J + 15) = J - 1
J + 15 = 3(J - 1)
J + 15 = 3(J - 1)
This is the answer.

The parabola opens upward has x = 2 as an axis of symmetry and contains the non -vertex points (1, 9) and (4, 27) write the equation in vertex form for this parabola .
Answer:
f(x) = 6(x - 2)² + 3Step-by-step explanation:
f(x) = a(x - h)² + k - vertex form of the equation of the parabola with vertex (h, k)
"the parabola opens upward" means: a>0
"the parabola has x = 2 as an axis of symmetry" means: h = 2
so f(x) = a(x - 2)² + k
"the parabola contains the point (1, 9)" means:
9 = a(1 - 2)² + k
9 = a(-1)² + k
9 = a + k
k = 9 - a
"the parabola contains the point (4, 27)" means:
27 = a(4 - 2)² + k
so:
27 = a(2)² + 9 - a
27 = 4a + 9 - a
3a = 18
a = 6
and k = 9 - 6 = 3
Therefore the vertex form for this parabola is:
f(x) = 6(x - 2)² + 3

A rectangular piece of plastic sheet measures 1m by 70cm.
find its cost at the rate of Rs. 80 per metre.
[tex]\huge\underline{\overline{\mid{\bold{\red{ANSWER}}\mid}}}[/tex]
Area of Rectangular sheet = 1m X 0.7 m = [tex] 0.7m^{2}[/tex] or [tex]70 cm^{2} [/tex]
Rate = Rs.80 per [tex] meter^{2} [/tex]
= [tex] 0.7m^{2} \times 80 = 56 [/tex]
hence, The cost will be Rs. 56 for the plastic sheet.
Step-by-step explanation:
Area of Rectangular sheet = 1m X 0.7 m = 0.7m^{2}0.7m
Area of Rectangular sheet = 1m X 0.7 m = 0.7m^{2}0.7m 2
Area of Rectangular sheet = 1m X 0.7 m = 0.7m^{2}0.7m 2 or 70 cm^{2} 70cm
Area of Rectangular sheet = 1m X 0.7 m = 0.7m^{2}0.7m 2 or 70 cm^{2} 70cm 2
Area of Rectangular sheet = 1m X 0.7 m = 0.7m^{2}0.7m 2 or 70 cm^{2} 70cm 2
Area of Rectangular sheet = 1m X 0.7 m = 0.7m^{2}0.7m 2 or 70 cm^{2} 70cm 2 Rate = Rs.80 per meter^{2} meter
Area of Rectangular sheet = 1m X 0.7 m = 0.7m^{2}0.7m 2 or 70 cm^{2} 70cm 2 Rate = Rs.80 per meter^{2} meter 2
Area of Rectangular sheet = 1m X 0.7 m = 0.7m^{2}0.7m 2 or 70 cm^{2} 70cm 2 Rate = Rs.80 per meter^{2} meter 2
Area of Rectangular sheet = 1m X 0.7 m = 0.7m^{2}0.7m 2 or 70 cm^{2} 70cm 2 Rate = Rs.80 per meter^{2} meter 2 = 0.7m^{2} \times 80 = 56 0.7m
Area of Rectangular sheet = 1m X 0.7 m = 0.7m^{2}0.7m 2 or 70 cm^{2} 70cm 2 Rate = Rs.80 per meter^{2} meter 2 = 0.7m^{2} \times 80 = 56 0.7m 2
Area of Rectangular sheet = 1m X 0.7 m = 0.7m^{2}0.7m 2 or 70 cm^{2} 70cm 2 Rate = Rs.80 per meter^{2} meter 2 = 0.7m^{2} \times 80 = 56 0.7m 2 ×80=56
Area of Rectangular sheet = 1m X 0.7 m = 0.7m^{2}0.7m 2 or 70 cm^{2} 70cm 2 Rate = Rs.80 per meter^{2} meter 2 = 0.7m^{2} \times 80 = 56 0.7m 2 ×80=56hence, The cost will be Rs. 56 for the plastic sheet.
