5X-50+2X+80-X=180..............

Answers

Hey there!

5x - 50 + 2x + 80 - x = 180

COMBINE the LIKE TERMS

= 6x + 30 = 180

SUBTRACT 30 to BOTH SIDES

6x + 30 - 30 = 180 - 30

CANCEL out: -30 - 30 because that gives you 0

KEEP: 180 - 30 because it helps solve for the x-value

6x = 180 - 30

180 - 30 = 150

NEW EQUATION: 6x = 150

DIVIDE 6 to BOTH SIDES

6x/6 P 150/6

CANCEL out: 150/6 because that gives you the result of the x-value

x = 150/6

SIMPLIFY IT!

x = 25

Therefore, your answer is: x = 25

Good luck on your assignment and enjoy your day!

~Amphitrite1040:)

If you are solving for X, the answer will be 25. To solve this, isolate the variable by dividing each side by factors that don’t contain the same variable
Hope this helps :)

If f(x) is an exponential function where f(-2) = 1 and f(7) = 63, then find the
value of f(1), to the nearest hundredth.

Answers

An exponential function is represented as: [tex]\mathbf{f(x) = ab^x}[/tex]

The value of f(1) is 3.95

f(-2) = 1 means that:

[tex]\mathbf{ab^{-2} = 1}[/tex]

f(7) = 63 means that:

[tex]\mathbf{ab^{7} = 63}[/tex]

Divide both equations

[tex]\mathbf{\frac{ab^7}{ab^{-2}} = \frac{63}{1}}[/tex]

Apply law of indices

[tex]\mathbf{b^9 = 63}[/tex]

Take 9th root of both sides

[tex]\mathbf{b =1.58}[/tex]

Make a, the subject in [tex]\mathbf{ab^{-2} = 1}[/tex]

[tex]\mathbf{a = \frac{1}{b^{-2}}}[/tex]

[tex]\mathbf{a = b^2}[/tex]

Substitute [tex]\mathbf{b =1.58}[/tex]

[tex]\mathbf{a = 1.58^2}[/tex]

[tex]\mathbf{a = 2.50}[/tex]

So, we have:

[tex]\mathbf{f(x) = ab^x}[/tex]

[tex]\mathbf{f(x) = 2.50 \times 1.58^x}[/tex]

Substitute 1 for x

[tex]\mathbf{f(1) = 2.50 \times 1.58^1}[/tex]

[tex]\mathbf{f(1) = 3.95}[/tex]

Hence, the value of f(1) is 3.95

(3, 9)

Step-by-step explanation:

First, what does it mean to move left 5 units from your starting position?

Second, how does that change were you are at this point?

ok so I start at (8, 9). I move left 5 units. Where do I end?

Since moving to the left changes my x variable, subtract 5 from 8

8 - 5 = 3

so that means my final position is at (3, 9)

Find the measure of each marked angle.

Answers

Answer:

X= 15, m∠78°

Step-by-step explanation:

Since the angles are vertically opposite

Therefore their measurements are equal

Therefore (2x + 48 ) = (5x + 3 )

So,

[tex](2x + 48) = (5x + 3)\\(2x-5x)= (3-48)\\-3x = -45\\x = -45/-3\\x = 15[/tex]

[tex](2x + 48)\\=( 2* 15 + 48)\\= 30 + 48\\=78\\\\(5x + 3)\\=(5*15 + 3)\\=75+3\\=78[/tex]

They both equal 78°

10x47=$4.70

1x20=$0.20

$4.70+$0.20=$4.90

Gap= $3.40
