Answer:

The slope-intercept equation of the line that goes through the points (1, 5) and (2, 8) is​ [tex]\mathbf{y=\frac{3}{2}x+\frac{7}{2} }[/tex]

Step-by-step explanation:

We need to find the slope-intercept equation of the line that goes through the points (1, 5) and (2, 8)

The general equation for slope intercept form is ​ [tex]y=mx+b[/tex] where m is slope and b is y-intercept

Finding slope

Slope can be found using formula [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

We have [tex]x _1=1, y_1=5, x_2=2, y_2=8[/tex]

Putting values and finding slope

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{8-5}{2-1}\\Slope=\frac{3}{2}[/tex]

So, we get slope [tex]m=\frac{3}{2}[/tex]

Finding y-intercept

y-intercept can be found using slope [tex]m=\frac{3}{2}[/tex] and point (1,5)

[tex]y=mx+b\\5=\frac{3}{2}(1)+b\\b=5- \frac{3}{2}\\b=\frac{10-3}{2}\\b=\frac{7}{2}\\[/tex]

So, we get y-intercept [tex]b=\frac{7}{2}[/tex]

Equation of line

So, equation of line having slope [tex]m=\frac{3}{2}[/tex] and y-intercept [tex]b=\frac{7}{2}[/tex] is:

[tex]y=mx+b\\y=\frac{3}{2}x+\frac{7}{2}[/tex]

The slope-intercept equation of the line that goes through the points (1, 5) and (2, 8) is​ [tex]\mathbf{y=\frac{3}{2}x+\frac{7}{2} }[/tex]

Answer:

244 ft²

Step-by-step explanation:

Rectangle Base Area: 6•4=24

Rectangle Side Area: 8•10=80; 80•2(sides) = 160

Triangle Sides Area: (10•6=60); 60/2(area of triangle) = 30; 30•2(sides)=60*

*Technically can skip the divide by two and then multiply by two, since they cancel out*

(Area of Triangle Formula= 1/2bh)

Add areas together: 24+160+60= 244 ft²

Answer:

x^2 / 4pi

Step-by-step explanation:

The area of a circle is (pi x r)^2

The circumference of a circle is 2pi x r

The find the radius, you need to divide x by 2pi, so x / 2pi

Then just plug it in as the radius:

(pi x (x / 2pi))^2 = x^2 / 4pi

Answer:

2n+10 and 2(n+5)

Step-by-step explanation:

[tex]2n + 10 \\ 2(8) + 10 = 26 \\ and \\ 2(n + 5) \\ = 2(8 + 5) \\ = 2(13) = 26 \\ \: hence \\ 2n + 10 = 2(n + 5) = 26[/tex]

Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. Light is refracted when it crosses the interface from air into glass in which it moves more slowly.

Answer:

A function is a relation in which each input has only one output. In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.

Answer:

[tex](3x^2 + 8)(x - 5)[/tex]

Step-by-step explanation:

Given

[tex]3x^3 - 15x^2 + 8x - 40 = 3x^2(x - 5) + 8(x - 5)[/tex]

Required

Complete the factorization

[tex]3x^3 - 15x^2 + 8x - 40 = 3x^2(x - 5) + 8(x - 5)[/tex]

When an equation is factorized as:

[tex]a(b + c) + d(b + c)[/tex]

The complete expression is:

[tex](a + d)(b + c)[/tex]

Apply this logic in [tex]3x^3 - 15x^2 + 8x - 40 = 3x^2(x - 5) + 8(x - 5)[/tex]

By comparison:

[tex]a = 3x^2; b = x; c = -5; d = 8[/tex]

So, we have:

[tex]3x^3 - 15x^2 + 8x - 40 = (3x^2 + 8)(x - 5)[/tex]

Hence,

[tex](3x^2 + 8)(x - 5)[/tex] is the complete factor

Answer:

Step-by-step explanation:

Answer:

x = 2

Step-by-step explanation:

7(3x + 5) - x = 75

1. Distributive property

multiply 7 by whatever is in the parenthesis

7*3x + 7*5 - x = 75

21x + 35 - x = 75

2. Combine like terms

21x - x = 20x

20x + 35 = 75

3. Subtract 35 on both sides

20x + 35 - 35 = 75 - 35

20x = 40

4. Divide both sides by 20 since u want to isolate the variable

20x/20 = 40/20

x = 2

And thats ur answer

Hope this helped!

Answer:A

Step-by-step explanation:A

Answer:

1/12 lb

Step-by-step explanation:

2/3 x 1/8 = 2/24 = 1/12

Step-by-step explanation: 2/3 / 8/1 is actually multiplying the first number by the reciprocal of the second. So 2/3 x 1/8. That equals 0.08333... or 1/12.

Hope this helps!

Answer: a=mx+b

Step-by-step explanation:

Answer:

b = 12 cm

Step-by-step explanation:

The Pythagora's Theorem

The area of a square of side length x is

[tex]A = x^2[/tex]

We have three squares, two of which have side lengths of a=5 cm and b= 13 cm.

The combined area of the smaller squares is the same as the area of the largest square. We cannot say at first sight which square is the largest, we'll assume the square of side length of 13 cm is the largest one. Thus:

[tex]5^2+b^2=13^2[/tex]

Where b is the unknown side length.

The above expression corresponds to the Pythagora's Theorem formula. Solving for b:

[tex]b^2={13^2-5^2=169-25=144[/tex]

[tex]b=\sqrt{144}[/tex]

b = 12 cm

Answer:

Linear equations take the form: y = mx + c

y is the dependent variable i.e the money that Naomi has to pay in total.

x is the independent variable which in this case is weeks.

m is the slope and this shows the change as a result of x. It should therefore represent the weekly payment as this is increases per week.

c is a the y-intercept which means its a fixed figure that doesn't change. It will therefore be the down payment because that does not change.

Plan A:

Naomi wants to pay $840. Using the formula format and explanation above (replace x with w so it makes more sense), the formula will be:

840 = 60w + 180

Plan B:

This has no down payment so there will be no y-intercept.

840 = 70w

Answer:

y= 1x-5

Step-by-step explanation:

This grpah shows a linear equation, for which the formula is y=mx+b. M is the slope, and b is the y-intercept, which means the point on the y-axis when x is zero.

So far= y=_x-5

Now to find the slope, you can take 2 points and use the slope formula, which is [tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]

I used the points (1,-4) and (0, -5)

(1,-4)

[tex]x_{2} , y_{2}[/tex]

(0,-5)

[tex]x_{1} ,y_{1}[/tex]

Plug into formula

[tex]\frac{-4-(-5)}{1-0}[/tex]

negative minus negative becomes a positive

[tex]\frac{-4+5}{1}[/tex]

[tex]\frac{1}{1}[/tex]

The slope is 1, so the equation of the graph is

y= 1x-5

Answer:

The answer would be 6.2 if you round to the nearest tenth.

Step-by-step explanation:

[tex]2 = {x}^{2} + 5x[/tex]

[tex]0 = {x}^{2} + 5x - 2 \\ {x}^{2} + 5x - 2 = 0[/tex]

From the standard form equation and from the given equation.

[tex]a {x}^{2} + bx + c = 0 \\ a = 1 \: \: \: b = 5 \: \: \: c = - 2[/tex]

Discriminant Formula

[tex]D = {b}^{2} - 4ac[/tex]

Substitute the value of terms in the discriminant formula.

[tex]D = {(5)}^{2} - 4(1)( - 2) \\ D = 25 - 4( - 2) \\ D = 25 + 8 \\ D = 33[/tex]

Discriminant Types

[tex]D > 0 \: \: \: \: 2 \: \: real \: \: roots \\ D = 0 \: \: \: \: 1 \: \: real \: \: root \\ D < 0 \: \: \: imaginary \: \: roots[/tex]

We can rule out the Imaginary root and double root because the discriminant is greater than 0. Therefore, the only choices are either Irrational or Rational.

However, we cannot factor the expression by using two brackets or common factor. We can say that the equation has two real irrational roots.
