What is the solution to this system of equations?
y = x +4
x+y= 2
Answer:
x = -1 y = 3
Step-by-step explanation:
x + (x + 4) = 2
x + x + 4 = 2
2x = -2
x = -1
y = -1 + 4
y = 3
Answer:
y = 3
x = - 1
Step-by-step explanation:
x + y + x + 4 = y + 2
x + y - y + x + 4 = y - y + 2
x + x + 4 = 2
2x + 4 = 2
2x + 4 - 4 = 2 - 4
2x = - 2
2x ÷ 2 = - 2 ÷ 2
x = - 1
y = x + 4
y = - 1 + 4
y = 3

i can't see the 4th option but from what i can see, i'd say 20 (b).
i didn't do math for this, i just used context clues.
the hypotenuse is always longer than either of the sides, so if the hypotenuse is 29, then the only logical solution is 20 feet. every other option is >29.
Answer:
Hello! answer: 20 feet
Step-by-step explanation:
29 × 29 = 841 21 × 21 = 441 841 - 441 = 400 √400 = 20 20 × 20 = 400 therefore 20 is the answer Hope that helps!

y= 4x + 2
y= 4x + 6
How many solutions
0 solutions.
4x+2 is not = 4x+6
Therefore there will be Jo solutions
Answer:
no solutions
Step-by-step explanation:
Given the 2 equations
y = 4x + 2 → (1)
y = 4x + 6 → (2)
Substitute y = 4x + 2 into (2)
4x + 2 = 4x + 6 ( subtract 2 from both sides )
4x = 4x + 4 ( subtract 4x from both sides )
0 = 4 ← not possible
This indicates the system has no solution
Emily is solving the following System of equations using Substitution:
y=3x-4
y=2x+1
Her steps are shown below.
Part A
Click on the first step in which Emily made an error.
3x-4=2x+1
5x-4=1
5x=5
x=1
y=3(1)-4=3-4=-1
(1,-1)
Part B
Explain what Emily did wrong and then what she should have done to make sure it was the correct answer.
Answer:
Emily is solving the following system of equations using substitution:
y = 3x - 4
y = 2x + 1
Part A:
After substituting y's values:
3x - 4 = 2x + 1
What she did:
3x - 4 = 2x + 1
3x + 2x - 4 = 1
5x - 4 = 1
What she should have done:
3x - 4 = 2x + 1
3x - 2x - 4 = 1
x - 4 = 1
Part B:
This rule has not been followed: Sign changes when numbers shift from left to right of ' = 'sign.
Emily did not changed the sign of the number, 2x from + 2x to - 2x when it was moved from the right side to the left.

Find the unknown angle measure
Answer:
angle P=38°
angle Q = 38° [ Because this traingle is a isosceles triangle]
Step-by-step explanation:
This is just a guess I haven't done this in a long time
Take the Initial Angle ( 164 degrees )
subtract that from 180
you get 16
since the two unknown angles are parallel they are going to have the same angle
since there are two you divide 16 by 2
each angle is 8 degrees

Solve the equation
2x2 + 8x – 1 = 0
by completing the square.
Give your answers correct to 2 decimal places.
Step-by-step explanation:
[tex] {2x}^{2} + 8x - 1 = 0 \\ {x}^{2} + 4x - \frac{1}{2} = 0 \\ {x}^{2} + 4x + {( \frac{1}{4} )}^{2} - \frac{1}{2} - { (\frac{1}{4} )}^{2} = 0 \\ {(x + \frac{1}{4}) }^{2} - \frac{9}{16} = 0 \\ {(x + \frac{1}{4}) }^{2} = \frac{9}{16} \\ x + \frac{1}{4} = ±( \frac{ 3}{4} ) \\ x = \frac{1}{2} \: or \: - 1[/tex]
Answer:
Step-by-step explanation:
divide each term by 2 to begin with x²
x² + 4x - 1/2 = 0
now add 1 to each side
x² + 4x = 1/2
now divide 4 in half and square the result and add it to each side
x² + 4x + 4 = 1/2 + 4
(x + 2)² = 9/2

Jason is painting a large circle on one wall of his new apartment. The largest distance across the circle will be 8 feet. Approximately how many square feet of wall will the circle cover? Use 3.14 for π and round to the nearest hundredth. How much area will he cover if he painted a circle on three walls?
Answer:
a) 50.24 ft²
b) 150.72 ft²
Step-by-step explanation:
Jason is painting a large circle on one wall of his new apartment. The largest distance across the circle will be 8 feet.
The distance across a circle is also called a diameter, Hence,
D = Diameter = 8 ft
The Area of a circle = πr²
r = Diameter/2 = 8ft/2 = 4ft
π = 3.14
Hence,
The Area of the circle = π × (4 ft)²
= 50.24 ft²
a) Approximately the amount of wall the circle will cover is 50.24 ft².
b) How much area will he cover if he painted a circle on three walls?
This is calculated as:
1 wall = 50.24 ft²
3 walls = x
Cross Multiply
x = 3 × 50.24 ft²
x = 150.72 ft²
