Drag Each Equation To Show If It Could Be A Correct First Step To Solving The Equation3(x+8)=42.

Answers

Answer 1

Answer:

(3 x [tex]x[/tex]) + (3 x 8) = 42

Step-by-step explanation:

3(x+8) = 42

3*x + 3*8 = 42

3x + 24 = 42

3x = 42 -24

3x = 18

x = 18 / 3

x = 6

Hope this helps :)

Answer 2

Answer:

[tex]3(x+8) = 42\\=>(x+8) = 14[/tex]

[tex]3(x+8)=126\\=>x+8 = 42[/tex]

[tex]3(x+8) = 42\\=> 3x +24 = 42[/tex]

[tex]3(x+8) = 42\\=> 3\cdot x +3\cdot 8 = 42[/tex]

YES              

[tex]x +8 = 14\\3\cdot x +3\cdot 8 = 42\\3x + 24 =42[/tex]              

NO

[tex]3(x+8) = 126\\x+24 = 42\\3x+8 =42[/tex]

Find the value of x. (Type an integer or decimal.)

Answers

Answer:

70

Step-by-step explanation:

An angle formed by 2 tangent lines is equal to one half the measure of the major arc minus the measure of the minor arc.

we are given the minor arc ( 110 ) however we are not given the major arc.

Because circles make a 360 degree rotation we can find the major arc by subtracting the measure of the minor arc from 360

Thus, major arc = 360 - 110 = 250

Now that we have identified the major and minor arc we can find x

Recall that x = 1/2 ( major arc - minor arc )

Thus, x = 1/2 ( 250 - 110 )

250 - 110 = 140

140 / 2 = 70

Hence, x = 70

You are trying to find the side between the right angle and the degree (This is known as the adjacent)
You are given degree 42
You also given the longest side of 19 (This is known as the hypothenuse)
Cosine: adjacent/hypothenuse
Cos42 = x/19
0.7431448255 = x/19
x = 19 * 0.7431448255
x = 14.11975168, round to tenth

Solution: x = 14.1

A y=-x-6
B y=2x-3
C y=-1/2x -3
D y= x-3​

Answers

Answer:

what the. ok ok fine here Choose something close to (1.8,2.6)

Choice A

Step-by-step explanation:

Without the graph provided, I would prefer to do this algebraically.

y=2x-1

y=-1/4x+3

Since both are solved for y, I'm going to replace the first y with what the second y equals.

-1/4x+3=2x-1

I don't really like to deal with fractions quite yet so I'm going to multiply both sides by 4.

-1x+12=8x-4

I'm going to add 1x on both sides.

    12=9x-4

I'm going to add 4 on both sides.

    16=9x

I'm going to divide both sides by 9

   16/9=x

This is the same as saying x=16/9.

Now to find y, just choose one of the equations and replace x with 16/9.

y=2x-1

y=2(16/9)-1

y=32/9-1

y=32/9-9/9

y=(32-9)/9

y=23/9

So the exact solution is (16/9,23/9).

Round these numbers to the nearest tenths you get:

(1.8, 2.6) .

To get this I just typed into my calculator 16 divided by 9 and 23 divided by 9

16 divided by 9 gave me 1.777777777777777777777777777

23 divided by 9 gave me 2.5555555555555555555555555

So choose something close to (1.8, 2.6).

So your ordered pair (1.75,2.5) is pretty close to that so choice A.
