Answer: The actual length of a room that measures 2.8 inches on the blueprint will be 22.4 feet.

Step-by-step explanation:

We are given that ,

On a set of blueprints, the scale is \dfrac{1}{2}\text{inch= 4 feet}

Multiply 2 both sides , we get

Then, \text{1 inch = }2\times4=8\text{ feet}

\Rightarrow\ \text{2.8 inch = }2.8\times 8\text{ feet}

\Rightarrow\ \text{2.8 inch = }22.4\text{ feet}

Then, the actual length of a room that measures 2.8 inches on the blueprint.  will be 22.4 feet.

Hence, the correct answer is 22.4 feet.

Are -2x + 9 = 7 and 2x = 2 equivalent?​
DochEvi [55]

Answer:

Yes because the answer to both of them is 1

Step-by-step explanation:

Let's solve your equation step-by-step.

−2x+9=7

Step 1: Subtract 9 from both sides.

−2x+9−9=7−9

−2x=−2

Step 2: Divide both sides by -2.

−2x

−2

=

I don't understand this factorisation <br> a2+ 4a+3​
Tomtit [17]

Answer:

\boxed{\sf (a + 3)(a + 1)}

Step-by-step explanation:

\sf Factor  \: the  \: following:  \\  \sf \implies  {a}^{2}  + 4a + 3 \\  \\  \sf The \:  factors  \: of \:  3 \:  that \:  sum \:  to \:  4  \\ \sf are \:  3  \: and  \:  1. \\ \\  \sf So,  \\   \sf \implies {a}^{2}  + (3 + 1)a + 3 \\  \\  \sf \implies   {a}^{2}  + 3a + a + 3 \\  \\  \sf \implies a(a + 3) + 1(a + 3)  \\  \\ \sf \implies (a + 3)(a + 1)

Which linear function represents the line given by the point-slope equation y – 8 = y minus 8 equals startfraction one-half endf
Marina CMI [18]

The linear function which represents the line given by the point-slope equation is (B) f(x)=\frac{1}{2} x+6.

<h3>What is a linear function?</h3>
  • The word linear function in mathematics refers to two distinct but related concepts.
  • A linear function in calculus and related fields is a function whose graph is a straight line, that is, a polynomial function of degree zero or one.

To find the linear function which represents the line given by the point-slope equation:

Given: y-8=\frac{1}{2} (x-4)

Distribute the right side:

y-8=\frac{1}{2} (x)-\frac{1}{2} 4\\y-8=\frac{1}{2} x-2

Adds 8 on both sides:

y=\frac{1}{2}x-2+8\\y=\frac{1}{2}x+6

Convert to function notation:

f(x)=y\\f(x)=\frac{1}{2} x+6

Therefore, the linear function which represents the line given by the point-slope equation is (B) f(x)=\frac{1}{2} x+6.

The complete question is given below:

Which linear function represents the line given by the point-slope equation y – 8 = y minus 8 equals start fraction one-half end fraction left-parenthesis x minus 4 right-parenthesis. (x – 4)?

A) F(x) = f(x) equals StartFraction one-half EndFraction x plus 4.X + 4

B) f(x) = f(x) equals StartFraction one-half EndFraction x plus 6.

C) X + 6 f(x) = f(x) equals StartFraction one-half EndFraction x minus 10.X –10

D) f(x) = f(x) equals StartFraction one-half EndFraction x minus 12.X – 12
