What is the solution
y=-x+2
y=-3x-2
Answer: (-2, 4)
Concept:
There are three general ways to solve systems of equations:
Elimination: using addition/subtraction to cancel out variables.Substitution: when two variables appear in both equations and are isolated, they could substitute each other.Graphing: graph the equations to find the intersection for the solution.Here we are going to use substitution since the variable [y] is being isolated in both equations.
Solve:
Given equations
y = -x + 2
y = -3x - 2
Using the method of substitution to combine the equations
-x + 2 = -3x - 2
Add 3x on both sides
-x + 2 + 3x = -3x - 2 + 3x
2x + 2 = -2
Subtract 2 on both sides
2x + 2 - 2 = -2 - 2
2x = -4
Divide 2 on both sides
2x / 2 = -4 / 2
[tex]\boxed{x=-2}[/tex]
Find the y value
y = -x + 2 →→→ Given expression
y = -(-2) + 2 →→→ Substitute values into the expression
y = 2 + 2 →→→ Simplify the value
[tex]\boxed{y=4}[/tex] →→→ SImplify by addition

a museum director wants to hang the painting on a wall. To the nearest foot, how tall does the wall need to be.
the painting is the square root of 90 ft
help!
Answer:
10ft
Step-by-step explanation:
I'm not quite sure I understand your question because you seem to have already stated the height of the wall but I found a similar one (see attached).
If the height of the picture is √90 feet. This means it is;
√90 = 9.5 ft
Rounded to the nearest foot is 10 feet.
To be able to hang the painting, the wall would have to be at least 10 ft in height.
The height of the wall should be at least 9.5 feet.
What is an expression?
Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that a museum director wants to hang the painting on a wall the height of the painting is √90 feet.
Height = √90
Height = 9.48 feet
Therefore, the height of the wall should be at least 9.5 feet.

best buy has a store brand tv for $700. this is $250 more than 1/4 of the cost of a deluxe model that they also carry. what is the price of the deluxe model that best buy has in their store?
Answer:
1800 Dollars
Step-by-step explanation:
If a 700 dollar tv is 250 dollars more than a quarter the cost of another tv, that means that 700 - 250 = 450, which multiplied by 4 equals 1800 which would be the price of the tv
Answer:
$812.50
Step-by-step explanation:
Make an equation:
700 = 250 + 1/4x
700 is the store brand version250 + 1/4x is the price of the deluxe t.v.Solve:
700 = 250 + 1/4x
-250 -250

2. Ifj(x) = x2 + 1, find j(a + 1).
Step-by-step explanation:
if you mean x multiply 2 :
j(x) = 2x + 1
j(a+1) = 2(a+1) + 1
= 2a+ 2 +1
=2a + 3
if you mean x to the power of 2

The number of eggs will be 28, which Bridget collected from the chickens this morning.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Given that, Bridget collected the eggs her chickens had laid and gave ½ to her neighbor.
The equation below represents Bridget's original collection.
⇒ (e/2) - 6 = 8
⇒ e/2 = 8 + 6
Apply the addition operation,
⇒ e/2 = 14
Multiply by 2 into both sides of the above equation
⇒ 2 × e/2 = 2 × 14
⇒ e = 28
Therefore, the number of eggs will be 28, which Bridget collected from the chickens this morning.
