Answer:
y = x + 5
Step-by-step explanation:
Find any two points:
(1, 6)
(2, 7)
Slope = (y2 - y1) / (x2 - x1)
S0:
7 - 6 / 2 - 1
1 / 1
So slope = 1
Equation:
y = mx + b
Plug in the numbers using the x and y of any points:
7 = m * 2 + b
Add m (which is the slope):
7 = 1 * 2 + b
7 = 2 + b
Subtract two from both sides:
5 = b
So our equation is:
y = x + 5
Please let me know if I've done anything wrong!
Answer:
y = x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 5, 0) and (x₂, y₂ ) = (0, 5) ← 2 points on the line
m = [tex]\frac{5-0}{0+5}[/tex] = [tex]\frac{5}{5}[/tex] = 1
The line crosses the y- axis at (0, 5 ) ⇒ c = 5
y = x + 5 ← equation of line
Whats the factored form of the trinomial 2x^2-26x-60
Answer: Plz mark me brainlest
Step-by-step explanation:
You can factor out a 2, so do that first
2(x^2 - 13x + 30) = 0
Now look at x^2 - 13x + 30. Since you have a positive last term and a negative middle term, then you're looking for something in the form of (x - ?)(x - ?). We have to find two numbers whose product is 30 and whose sum is 13. The numbers must be 10 and 3:
2(x-3)(x-10) = 0

easy points plz solve quick!
Answer:
-2
Step-by-step explanation:
Rearrange:4*x+12-(-2*x)=0
Pull out like factors:6x + 12 = 6 • (x + 2)
Solve:x+2=0
Subtract 2 from both sides of the equation:x = -2
Answer:
x = -2
Step-by-step explanation:
4x + 12 = -2x
4x + 12-12 = -2x - 12
4x = -2x - 12
4x + 2x = -2x - 12 + 2x
6x = -12
x = -2

PLS HELP TY
Answer:
y=-3x+9
Step-by-step explanation:
The slope of the line through two points (x1,y1) and (x2,y2) can be found by using the formula below. Don't forget slope is rise over run: subtract the y-values in the numerator to get the rise and subtract the x-values in the denominator (in the same order!) to get the run. Once you know the slope (m), you're halfway there. Now all that's left to find is the y-intercept (b). To find the y-intercept, choose one of the points on the line. It does not matter which point you choose (just pick the one that looks easiest to you). Plug in the values for x and y into the equation and solve for b.

What is algebra?A part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.
Given:
The equation is
1 – (2x + 4) = –4x + 5,
we have to find the correct solution of the equation;
According to given question we have,
Step 1: Open the parenthesis we get,
1 – (2x + 4) = –4x + 5
1-2x-4 = -4x + 5
1-4-2x = -4x +5
-3-2x = -4x + 5
Step 2: Collect like terms we get,
-2x + 4x = 5 + 3
2x = 8
Step 3: divide both sides by 2 we get,
2x/2 = 8/2
x = 4
Hence the correct value of x is 4.

Which statement describes the sequence −9, −3, 3, 9, 15?
A. An arithmetic sequence with common difference −9
B. An arithmetic sequence with common difference 3
C. An arithmetic sequence with common difference 6
D. Not an arithmetic sequence
Answer:
C. An arithmetic sequence with a common difference of 6.
Step-by-step explanation:
A is incorrect because the common difference is not -9 (not constant).
B is incorrect because the common difference is not 3 (not constant).
C is the correct answer because the common difference is 6 (constant).
D is incorrect because this is an arithmetic sequence.
-------------------------------------------------------------------------------------------------------
-9 + 6 = -3
-3 + 6 = 3
3 + 6 = 9
9 + 6 = 15
The common difference is +6 (positive 6).

The progression −9, −3, 3, 9, 15 is an arithmetic sequence with a common difference of 6. The correct option is C.
What is an arithmetic progression?The sequence in which every next number is the addition of the constant quantity in the series is termed the arithmetic progression.
Given series is −9, −3, 3, 9, 15.
The common difference is calculated as,
-9 + 6 = -3
-3 + 6 = 3
3 + 6 = 9
9 + 6 = 15
As above it is observed that with the common difference of 6 we found the series, −9, −3, 3, 9, 15.
Therefore, the progression −9, −3, 3, 9, 15 is an arithmetic sequence with a common difference of 6. The correct option is C.

YOU SUBTRACT -4 ON BOTH SIDES SO YOU'LL GET X= 1/4
Answer:
x= 1/4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3/2(2−6x)+1=3−5x
(3/2)(2)+(3/2)(−6x)+1=3+−5x (Distribute)
3+−9x+1=3+−5x
(−9x)+(3+1)=−5x+3 (Combine Like Terms)
−9x+4=−5x+3
−9x+4=−5x+3
Step 2: Add 5x to both sides.
−9x+4+5x=−5x+5x+3
−4x+4=3
Step 3: Subtract 4 from both sides.
−4x+4−4=3−4
−4x=−1
Step 4: Divide both sides by -4.

How many square yards of carpet
are needed to cover the floor of
a room that is 18 feet long and
12 feet wide? (1 yd = 3 ft)
The area of the floor required to cover using carpet is equal to 24 square yards .
To calculate the area of the room in square yards,
convert the dimensions from feet to yards and then find the product of the length and width.
1 yard (yd) = 3 feet (ft)
Room length in yards
= 18 feet / 3 feet/yd
= 6 yards
Room width in yards
= 12 feet / 3 feet/yd
= 4 yards
Now, find the area of the room in square yards:
Area = Length × Width
Area = 6 yards × 4 yards = 24 square yards
Therefore, 24 square yards of carpet area required to cover the floor of the room.

36 3/4 gallons of water come out of a hose in 15 minutes. Write the ratio in fractional form and determine the water rate in gallons per hour. Group of answer choices 147 gallons per hour 73.5 or 73 1/2 gallons per hour 36.75 or 36 3/4 gallons per hour not possible
Answer:
147 gallons per hour
Step-by-step explanation:
Given:
36 3/4 gallons = 15 minutes
Determine the water rate in gallons per hour
1 hour = 60 minutes
60 minutes / 15 minutes = 4
Multiply both a of the proportion by 4
36 3/4 × 4gallons = 15 minutes × 4
147/4 × 4 gallons = 60 minutes
147 gallons = 60 minutes
147 gallons per hour
The correct answer = 147 gallons per hour

Answer:
If two angles are vertical angles, then they are congruent.
Step-by-step explanation:
If two angles are vertical angles, then they are congruent- this justifies why ∠FBE measures 50°.
What is an angle?In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.
We know that, a ray is a line that continues on forever inn one direction with a point at it's start.
Here, given that,
angles ABD and DBC are complementary
Now, we get,
