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
LLoyd used 1/4 of chocolate to make 2/3 gallons of chocolate pudding. If Lloyd's recipe is for 1 gallon of pudding, how many pounds of chocolate will he need to make 1/3 the recipe?
Answer:
1/8
Step-by-step explanation:
Llyod used 1/4 chocolates to make 2/3 gallons of chocolate pudding
= 1/4 ÷ 2/3
= 1/4 × 3/2
= 3/8
Therefore the number of pounds needed to make 1/3 of the recipe can be calculated as follows.
= 3/8 × 1/3
= 3/24
= 1/8
-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

The table shows a relationship between values of x and y.
Which of the following equations describes the relationship for the values in the table?
A.
y = 2x^2 – 1
B.
y = x^2 + 3
C.
y = 2x^2 + 1
D.
y = 10x – 3
Answer:
A. y = 2x^2 - 1Step-by-step explanation:
Try the points of x and y by substitution
This gives us the function:
y = 2x^2 - 12. f(x) = (x -2)^2 +4

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"

[tex]2x^2-20x=x^{2} -19[/tex]
Answer:
x = 1, x = 19
Step-by-step explanation:
Given
2x² - 20x = x² - 19 ( subtract x² - 19 from both sides )
x² - 20x + 19 = 0 ← in standard form
(x - 1)(x - 19) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
x - 19 = 0 ⇒ x = 19

What is the value of p?
the answer is p=6
hope that helped loll
Answer: 6
Step-by-step explanation:
In a triangle, all three angles always add to 180°.
Thus, simply do 180 - 96 - 54 to get the angle, 30. Then, because the angle is 5p, divide 30/5 = 6.

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
