A coordinate plane with a line passing through points (1, 2) and (4, 4)
The slope of the graphed line is . Which formulas represent the line that is graphed? Check all that apply.
y – 1 = (x – 2)
y – 2 = (x – 1)
y – 4 = (x – 4)
f(x) = x +
f(x) = x +
A straight line is represented by a linear equation given below.
The points are given as (1, 2) and (4, 4).
Start by calculating the slope (m)
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
So, we have
[tex]m=\frac{4-2}{4-1} \\m=\frac{2}{3}[/tex]
What is the slope-intercept form of the line?The equation in slope-intercept form is then calculated as:
[tex]y=m(x-x_1)+y_1[/tex]
So, we have:
[tex]y=\frac{2}{3}(x-1)+2\\ \\y=\frac{2}{3}(x-4)+4\\[/tex]
Expand
[tex]y=\frac{2}{3}(x-1)+2\\ y=\frac{2}{3} x-\frac{2}{3}+2[/tex]

Answer:
cost of a doughnut is $0.75
cost of a cookie is $0.60
Step-by-step explanation:
As you wrote:
Let x = doughnuts
Let y = cookies
The first sentence of the problem (alexandra) can be written as:
[tex]2x + 3y = 3.30[/tex]
The second sentence of the equation (briana) can be written as:
[tex]5x + 2y = 4.95[/tex]
We must now solve for either [tex]x[/tex] or [tex]y[/tex] in this system of equations.
I will solve for [tex]x[/tex] in this example.
First we need to multiply the first equation by [tex]2[/tex] and the second equation by [tex]3[/tex]. This is so both equations have [tex]6y[/tex] as a term.
Equation 1:
[tex]2(2x + 3y) = (3.30)2\\4x + 6y = 6.60[/tex]
Equation 2:
[tex]3(5x + 2y) = (4.95)3\\15x+6y=14.85[/tex]
Now that both equations have [tex]6y[/tex] as a term, we can subtract Equation 1 from Equation 2. This will remove y from the equation and allow us to solve for x.
[tex](15x+6y) - (4x+6y) = (14.85) - (6.60)\\11x = 8.25\\\boxed{x = 0.75}[/tex]
We now know the cost of a doughnut is $0.75. Now we can solve for the cost of a cookie through substitution.
[tex]2x + 3y = 3.30\\2(0.75) + 3y = 3.30\\1.50 + 3y = 3.30\\3y = 1.80\\\boxed{y = 0.6}[/tex]
Now we know the cost of a cookie is $0.60.

Write an equation that represents the line.
Step-by-step explanation:
a general line equation is
y = ax + b
"a" being the slope is the line, "b" being the y-intercept (the y value when x = 0).
we see from the 2 marked points (by we could choose any points on the line) that
y changes by 2 units, when x changes by 3 units.
so the slope is 2/3.
we use one point (1, 2) to solve for b
2 = 2/3 × 1 + b = 2/3 + b
6/3 = 2/3 + b
4/3 = b

3x² - 12x +9=0 using quadratic formula
Answer:
The quadratic equation 3x² - 12x + 9 = 0 has two real roots when solved:
x₁ = 1 and x₂ = 3
Step-by-step explanation:
✍ An equation of type ax² + bx + c = 0, can be solved, for example, using the quadratic formula:
[tex]\boldsymbol{x=\dfrac{-b\pm\sqrt{b^{2}-4ac } }{2a} }[/tex]
either
[tex]\boldsymbol{x=\dfrac{-b\pm\sqrt{\Delta} }{2a} }[/tex]
where
[tex]\bf{\Delta=b^{2}-4ac }[/tex]
Identify the coefficients
a = 3, b = -12 and c = 9
Calculate the discriminant value
Δ = b² - 4ac
Δ = (-12)² - 4.3.9 = 144 - 12.9
Δ = 144 - 108 = 36
Enter the values of a, b and the discriminant value in the quadratic formula
[tex]\boldsymbol{x=\dfrac{-b\pm\sqrt{\Delta } }{2a} }[/tex]
[tex]\boldsymbol{x=\dfrac{-(-12\pm\sqrt{36} }{2\cdot3 } }[/tex]
[tex]\boldsymbol{x=\dfrac{(12\pm\sqrt{36} }{6 } \ ==== > \ (Solution \ general) }[/tex]
As we can see above, the discriminant (Δ) of this equation is positive (Δ> 0) which means that there are two real roots (two solutions), x₁ and x₂.

Answer:
23.292°
Step-by-step explanation:

The value of x to the nearest tenth is 23.3°.
What is Law of Sines?Law of sines is defined as that ratio of the length of the sides of a triangle to the sine of the angle opposite to the these sides are equal.
That is, if a, b and c are sides opposite to the angles A, B and C respectively, then,
a / sin A = b / sin B = c / sin C
Given is a triangle ABC.
Using the law of sines,
AB / Sin C = BC / Sin A
We have to find the angle A.
Substituting,
18 / sin 22 = 19 / sin x
18 × sin(x) = 19 × sin (22°)
sin(x) = (19 × sin (22°)) / 18
sin x = 0.3954

Please help me solve this composite shape step by step
Answer:
73 cm²
Step-by-step explanation:
Areas and volumes of composite figures are found by dividing the figure into shapes you have formulas for. Sometimes that will be a sum of shapes, and sometimes it will involve the difference of shapes.
__
setupThis shape can be decomposed into two rectangles by extending the horizontal line. (This is the dashed line shown in the attachment.)
The width of the top rectangle will be the sum of the lengths of the labeled horizontal segments:
4 cm + 5 cm + 3 cm = 12 cm
The height of the top rectangle, and the dimensions of the bottom rectangle (square) are shown in the given figure.
The area of each rectangle is the product of its width and height.
A = WH
__
solutiontop rectangle area = WH = (12 cm)(4 cm) = 48 cm²
bottom rectangle area = WH = (5 cm)(5 cm) = 25 cm²
Area = top rectangle area + bottom rectangle area = (48 cm²) +(25 cm²)
Area = 73 cm²
The area of this composite shape is 73 cm².
_____
Additional comment
The figure will fit into a rectangle that is 9 cm high by 12 cm wide. From that rectangle, a rectangle 5 cm high and 4 cm wide is removed from the lower left, and a rectangle 5 cm high and 3 cm wide is removed from the lower right. Figuring the area this way, we find it to be ...
figure area = bounding rectangle area - removed areas
= (9 cm)(12 cm) -(5 cm)(4 cm) -(5 cm)(3 cm) = 108 cm² -20 cm² -15 cm²

Answer:
The value of m in the figure is 28.
Step-by-step explanation:
When we look at the figure, we see that 6 and 21, are connected with parallel lines to 8 and m. We can also see that 21 is dilated from 6. When dilating, we multiply or divide by a number, to get the extended or shortened length. (Just keep multiplication and division in mind)
To get m, we can do the same that we did to get 21, from 6.
To get 21 from 6, you must divide 21 by 6. So when we do the same thing to 8, we should get m.
21 / 6 = 3.5
Now that we have the dilation of 3.5, we simply multiply that by 8.
3.5 * 8 = 28
The value of x in the figure is 28.

What is the probability that you would land on a R and then a P?
Answer:
multiply the probability of the first event by the second.
Step-by-step explanation:
Use the specific multiplication rule formula. Just multiply the probability of the first event by the second. For example, if the probability of event A is 2/9 and the probability of event B is 3/9 then the probability of both events happening at the same time is (2/9)*(3/9) = 6/81 = 2/27.
Answer:
[tex]\frac{1}{26} * \frac{1}{26} = \frac{1}{676} = .00148.[/tex]
Step-by-step explanation:
Multiply the probability of P by the probability of Q.
In which the probability of P is equal to [tex]\frac{R}{Total NumberOf LettersInAlphabet} = \frac{1}{26}[/tex]
In which the probability of Q is equal to [tex]\frac{P}{Total NumberOf LettersInAlphabet} = \frac{1}{26}[/tex]
There's a 1 in 676 chance that you'd randomly pick R, put the tile back in, and then pick P in a sack of 26 letters of the latin alphabet.

Examples:
1 hour = 60 minutes
1 minute = 60 seconds
1 km = 1000 m
We have,
Let's convert the length of the rope to inches.
1 meter = 39.37 inches
2.50m = 98.43 inches
Now,
The number of 1.5-inch pieces.
= 98.43 / 11.5
= 8.55 pieces
Now,
11.5 inches pieces are cut.
This means,
= 98.43 - (8x11.5)
= 7.43 inches
Now,
1 inch = 2.54 cm

give brainliest please!
hope this helps :)
so these two angles add up to 180 degrees
7x -3 + 12x -7 = 180
7x+12x=180+7+3
19x=190
x=10
to check if this is true we can input 10 for x in each side.
7(10)-3 = 67
12(10)-7 = 113
113+67 = 180
