Answer:
(x, y) = (-4, 3)
Step-by-step explanation:
x + y = -1 $|Rightarrow$ x = -1 - y
x - y = -7
Substituting the value of x (first equation) into the second equation, we get:
(-1 - y) - y = -7.
Simplifing, we get:
-1 -2y = -7
-2y = -6
y = 3.
Now that we know the value of y, we can solve the value of x by substituting y into the first equation. We get:
x = -1 - 3
x = -4
13 percent increase of 130
4x squared plus 4y plus 3x plus 2y squared

Look at this graph:
Determine whether the graph represents a function.
Answer:
true
Step-by-step explanation:
here this might help a little Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.

y=-3x + 10
y = -2x + 6
Substitution method
Answer:
x=4 and y=−2
Step-by-step explanation:
y=−3x+10;y=−2x+6
Step: Solve y=−3x+10for y:
Step: Substitute−3x+10foryiny=−2x+6:
y=−2x+6
−3x+10=−2x+6
−3x+10+2x=−2x+6+2x(Add 2x to both sides)
−x+10=6
−x+10+−10=6+−10(Add -10 to both sides)
−x=−4
-x/-1 = -4/-1 (Divide both sides by -1)
x=4
Step: Substitute4forxiny=−3x+10:
y=−3x+10
y=(−3)(4)+10
y=−2(Simplify both sides of the equation)
Answer:
Solution is the point (4, -2)
Step-by-step explanation:
use the expression for y from the first equation in the second equation:
then the equation y = - 2 x + 6 becomes:
- 3 x + 10 = - 2 x + 6
add 3 x to both sides
10 = 3 x - 2 x + 6
10 = x + 6
subtract 6 from both sides
x = 4
Now replace x with 4 in the first equation to find y:
y = - 3 x + 10 = - 3 (4) + 10 = - 12 + 10 = -2
Therefore this is the point solution to the system:
(4, -2)

9514 1404 393
Answer:
19.25 miles
Step-by-step explanation:
Antoine's rate before lunch was ...
(5.25 mi)/(3 h) = 1.75 mi/h
Then his rate after lunch was ...
2×(1.75 mi/h) = 3.5 mi/h
The distance he hiked after lunch was ...
distance = speed × time
(4 h)×(3.5 mi/h) = 14 mi
The distance Antoine hiked is the total of his before-lunch distance and his after-lunch distance:
5.25 mi + 14 mi = 19.25 mi

Answer:
Step-by-step explanation:
y -5x = 2
10x -3y =9
substitute x for 3/5 and y for -1
-1 -(5*3/5) = 2
(10*3/5) -3(-1) =9
simplify :

after completing the square what are the solutions to the quadratic equation below
x²-5x-6=3
Answer:
x = 5/2 + sqrt(61)/2 or x = 5/2 - sqrt(61)/2
Step-by-step explanation:
Solve for x over the real numbers:
x^2 - 5 x - 6 = 3
Hint: | Solve the quadratic equation by completing the square.
Add 6 to both sides:
x^2 - 5 x = 9
Hint: | Take one half of the coefficient of x and square it, then add it to both sides.
Add 25/4 to both sides:
x^2 - 5 x + 25/4 = 61/4
Hint: | Factor the left hand side.
Write the left hand side as a square:
(x - 5/2)^2 = 61/4
Hint: | Eliminate the exponent on the left hand side.
Take the square root of both sides:
x - 5/2 = sqrt(61)/2 or x - 5/2 = -sqrt(61)/2
Hint: | Look at the first equation: Solve for x.
Add 5/2 to both sides:
x = 5/2 + sqrt(61)/2 or x - 5/2 = -sqrt(61)/2
Hint: | Look at the second equation: Solve for x.
Add 5/2 to both sides:
Answer: x = 5/2 + sqrt(61)/2 or x = 5/2 - sqrt(61)/2

ANSWER FOR A BRAINLIEST Solve the system of two variables by substitution
Answer:
Substitution is when you isolate a variable-
3) We can divide the first equation by 6 to get x+y=-1, then isolate to get y=-1-x. We plug this into the second equation to have 3x+(-1-x)=-13. We simplify and get 2x=-12 so x=-6. We plug this back into the first equation and get -6+y=-1 so y=5. So the answer as an ordered pair is (-6,5).
4) We can isolate the second equation to get x=2y+11. We substitute this into the first equation to have -7(2y+11)-2y=-13. We simplify and get -16y=64 so y=-4. We plug this back into the second equation and get x+8=11 so x=3. So the answer as an ordered pair is (3,-4).

The value of x is 42 of three parallel lines intersected by two transversal lines
To solve for x in the given scenario of three parallel lines intersected by two transversal lines, we'll first determine the relationship between the corresponding angles.
According to the properties of parallel lines, corresponding angles are congruent. Thus, if we have an equation involving the corresponding angles, we can solve for x.
In this case, we have the equation:
x/35 = 30/25
To solve for x, we can cross-multiply:
25x = 30 * 35
25x = 1050
Dividing both sides by 25:
x = 1050/25
x = 42
Therefore, in the given scenario, the value of x is 42.
