using the elimination method how do I find x and y for the following problem:
4x-7y=13
4x + 7y = -29
Answer: x= -2 and y= -3.
Step-by-step explanation:
The given system of equations :
4x-7y=13 ...(i)
4x + 7y = -29 ....(ii)
By Elimination method, Eliminating (ii) from (i) , we get
[tex]-7y-7y=13-(-29)\\\\\Rightarrow\ -14y=13+29\\\\\Rightarrow\ -14y=42\\\\\Rightarrow\ y=\dfrac{42}{-14}\\\\\Rightarrow\ y=-3[/tex]
Now, Adding (i) and (ii), we get
[tex]8x=-16\\\\\Rightarrow\ x=\dfrac{-16}{8}\\\\\Rightarrow\ x=-2[/tex]
Hence, the solution is : x= -2 and y= -3.

The solution of the system of linear equation is given by (5,-5)
What are linear equations?Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.
Given here; The system of linear equations is given by
y=-x and 10x+2y=40
Solving for x by substituting y=-x we get
10x-2x=40
x=5
Then the y=-5
Hence, The solution of the system of linear equation is given by (5,-5)

3. REI.b4_Part A. A toy cannon ball is launched on top of a platform. The
equation h(t) =-8t +18t +6 gives the height, h in meters, of the ball t seconds
after it is launched. What equation can be used to tell whether the ball reaches
the height of 10 meters? *||
A. -8t^2 +18t +6 =0
B. -8t^2 +18t +6 =-10
o
C.-8t^2 +18t +6 = 12
o
D. -8t^2 +18t +6 = 10
Answer:
The correct option is;
D. -8·t² + 18·t + 6 = 10
Step-by-step explanation:
The given equation of the height toy cannon launched on top of a platform is given as follows;
h(t) = -8·t² + 18·t + 6...(1)
Where "h" represents the height in meters, at time "t" seconds after the ball is launched
When the height is 10 meters, we can write as follows;
The height of the ball, h(t) = 10
Therefore, by substituting the value of h(t) in equation (1), h(t) = -8·t² + 18·t + 6, when h(t) = 10 we get;
-8·t² + 18·t + 6 = 10.

Distribute
.05m +.6 =2
Subtract .6 from each side
.05m +.6-.6 = 2-.6
.05m = 1.4
Divide each side by .05
.05m/.05 = 1.4/.05

3.2b + 10 = -1.7b - 4.7
Answer:
b = -3
Step-by-step explanation:
3.2b + 10 = -1.7b - 4.7
add 1.7b to each side
3.2b+1.7b + 10 = -1.7b+1.7b - 4.7
4.9b +10 = -4.7
Subtract 10 from each side
4.9b +10-10 = -4.7-10
4.9b = -14.7
Divide each side by 4.9
4.9/4.9 = -14.7/4.9
b = -3

You're going on a 1211-mile trip, and your car gets about 29 miles per gallon. Gas prices along your route average $3.40. Estimate the cost of gasoline for this trip by rounding the distance to 1200 miles, the mileage to 30 miles per gallon, and the cost of gas to $3.00 per gallon. Calculate the answer without using estimate and compare the two results. (Round your answers to the nearest cent.)
Answer:
Using the estimate:
The car has to go for 1,200 miles but it consumes a gallon of gasoline for every 30 miles. The number of gallons it will need is therefore:
= 1,200 / 30
= 40 gallons
Each gallon costs $3.00 so the total cost is:
= 40 * 3
= $120
Without using the estimate:
The car has to go for 1,211 miles but it consumes a gallon of gasoline for every 29 miles. The number of gallons it will need is therefore:
= 1,211 / 29
= 41.76 gallons
Each gallon costs $3.40 so the total cost is:
= 41.76 * 3.40
= $141.98
Using the estimate provides a lower cost of gasoline for the trip.
