-4x+y=3 and 2x-y=12. which of the options represents the resulting equation after an equivalent expression for yw is substituted into the second equation. Odessyware!
Answer:
2x - (3 + 4x) = 12
x = -7.5
y = -27
Step-by-step explanation:
-4x + y = 3 (1)
2x - y = 12 (2)
From (1)
y = 3 + 4x
Substitute y = 3 + 4x into (2)
2x - y = 12 (2)
2x - (3 + 4x) = 12
2x - 3 - 4x = 12
2x - 4x = 12 + 3
-2x = 15
x = 15/-2
x = -7.5
Substitute x = -7.5 into (2)
2x - y = 12 (2)
2(-7.5) - y = 12
-15 - y = 12
-y = 12 + 15
- y = 27
y = -27
teri ran 4 kilometers . one mile is approximately equal to 1.6 kilometers. how many miles did teri run
Answer:
2.5 Miles
Step-by-step explanation:
4 k = ? Mile
1.6 k = 1 mi
4/1.6 is 2.5
1x2.5 equals 2.5
so 4 km should be 2.5 mi
4 k = 2.5 Mile
(x2.5)1.6 k = (x2.5)1 mi
1. If you wish to calculate the interest on an investment with an interest rate
of 2.85%, what number will you plug into your equation?"
0.00285
2.85
0.285
ОО
0.0285
=========================================
Explanation:
You move the decimal point two spots to the left to go from 2.85% to 0.0285
Or you can think of it like this:
2.85% = (2.85)/100 = 0.0285
since "percent" means "per 100"
Bobby is 5 less than Kylie's age. Their combined
age is 43. How old is Kylie?
Answer:
Kylie is 24 years old
Step-by-step explanation:
kylie = x
Bobby=x-5
x+x-5=43
2x-5=43
2x=43+5
2x=48
X=24 years old
19
If you subtract 5 off of 43 and divide it by two you find Kylie's age. The reason you divide by two is because there are two people and it is a combined age, meaning you would divide by two.

John leaves his home. He travels 5 blocks south and three blocks west. As the crow flies, how far is John from his home?
Answer:
5.83 blocks away from his home
Step-by-step explanation:
If he travels 5 blocks south and 3 blocks west, the distance from his house considered along with the distances travelled gives a right angled triangle whose opposite side and adjacent sides are the distances travelled north and west.
The distance from his house after moving 3 blocks west is the hypotenuse side. As such, the distance may be computed using Pythagoras' theorem. Let the distance from his house be G
G^2 = 5^2 + 3^2
G^2 = 25 + 9
= 34
G = √34
=5.83
John is 5.83 blocks away from his home

solve with subsitution
y-3x=2
y=-2x-8
show ur work HURRY PLSS
Answer:
y-3x=2......1
y=-2x-8 ......2
substituting value of y in equation 1
-2x-8-3x=2
-5x=2+8
x=10/-5=-2
substituting value of x in equation 1
y-3×(-2)=2
y+6=2
y=2-6=-4
x=-2
y=-4
(
Answer:
(-2, -4) or x = -2 y = -4
Step-by-step explanation:
Solve with subsitution
y-3x=2
y=-2x-8
1. Substitute -2x - 8 in for the y in y - 3x = 2 (-2x - 8) - 3x = 2
2. Solve for x. Combine like terms. -5x - 8 = 2
3. Solve the one step equation. +8 +8
-5x = 10
-5 -5
x = -2
4. Substitute the -2 in for x in either equation. y = -2x - 8
y = -2(-2) - 8
y = 4 - 8
y = -4
