Which equation is true when is x = 1

3x = 3

3x = 2

3x = 1

Answers

Answer 1

Answer:

3x = 3

Step-by-step explanation:

Since for 3x = 3, we can plug in the 1.

It becomes:

3(1) = 3

3 = 3

Thus, 3x =3 would be true if x = 1.

Writing a linear equations

Answers

Answer:

y = -4x + 5

Step-by-step explanation:

Equation of the line can be written as y = mx + b (slope-intercept form)

Where m = slope and b = y-intercept of the line.

Let's find m and b of the line

Slope (m) using the points (1, 1) and (0, 5),

Slope (m) = change in y/change in x

m = (5 - 1)/(0 - 1) = 4/-1

m = -4

Find b:

b = the point where the line cuts the y-axis = 5 (y-intercept)

To write the equation substitute m = -4 and b = 5 into y = mx + b

y = -4x + 5

Mhanifa please help asap! I need this done and i dont get it

Answers

To answer you use the Pythagorean theorem, a^2+b^2=c^2

10. C= 5
11. B= 2 V55 (2 square root of 55)
12. C= 2 V5
13. A= V5.39

Explanation:

10. a^2+b^2=c^2
3^2+4^2=c^2
9+16=c^2 (add 9 and 16)
25=c^2
V25= Vc^2 (take the square root of both sides to get):
5=c

11. 6^2+b^2=16^2
36+b^2=256 (256-36)
b^2=220 (square root, 220 cannot be simplified so you factor it and get):
b= 2 V55

12. 4^2+2^2=c^2
16+4=c^2
20=c^2 ( square root it then factor)
2 V5 = c

13. a^2+3.5^2=4.2^2
a^2+12.25=17.64 (subtract 17.64 and 12.25)
a^2=5.39 ( square root/ cannot be simplified so the square root of 5.39 is your answer)


I hope this helped you understand! I hope you have a good day!

Answer:

Use Pythagorean to find the missing side lengths.It assumed a and b are legs and c is the hypotenuse.All numbers are rounded to the nearest tenth.

#10

[tex]c = \sqrt{3^2+4^2} = \sqrt{25} = 5[/tex]

#11

[tex]b = \sqrt{16^2-6^2} = \sqrt{220} = 14.8[/tex]

#12

[tex]c = \sqrt{4^2+2^2} = \sqrt{20} = 4.5[/tex]

#13

[tex]a = \sqrt{4.2^2-3.5^2} = \sqrt{5.39} = 2.3[/tex]

Answer:

28. x = 3 31. x = -3

Step-by-step explanation:

4x=12

divide both sides by 4

4x/4 = 12/ 4

x = 3

x/-3 = 1

multiply both sides by -3

x/-3 (-3) = 1 (-3)

simplify both sides

x = -3

A business owner wants to have the front window of her store painted and is considering two
artists for the job. Tiana has quoted a flat rate of $292 for the job. Denise's quote is $39 per
hour, plus $19 to cover the cost of materials. Depending on how long it takes Denise to paint
the window, these two could end up charging the same amount. How long would Denise have
to take? How much would it cost?

Answers

denise would have to take seven hours to charge the same amount of money as tiana. furthermore, it would cost the same amount as that is what the prompt is asking for.

to get the answer:
i subtracted $19 from $292 to eliminate the
fee element because if you were to divide
$292 by $39 without the step, the hours would be incorrect and the price would be greater.

after subtracting i got $273

from there i divided $273 by $39 and got 7 (the amount of hours it would take)

[tex]\implies x = (-2) \qquad or\qquad x = \dfrac{-3}{2}[/tex]

Step-by-step explanation:

Given :-

A quadratic equation is given to us.The equation is 2x² + 7x +6=0

And we need to find out the roots of the given equation. We can use the middle term splitting method to find out the roots as ,

Given equation :-

[tex]\implies 2x^2 + 7x +6=0[/tex]

Step 1: Find out the factors of 12 :-

We will choose the two factors such that their sum equals to the coefficient of x i.e. 7 .The factors are , 1×12 , 2×6 , 3×4 .

And 3 + 4 = 7. So we will break the middle term into 3x and 4x .

Step 2 : Breaking the middle term :-

[tex]\implies 2x^2 + 3x+4x +6=0[/tex]

Step 3: Take out common from terms :-

[tex]\implies x(2x + 3) +2(2x +3)=0[/tex]

[tex]\implies ( x +2)(2x+3)=0 [/tex]

Step 4 : Equate them with 0 :-

[tex]\implies x = (-2) \qquad or\qquad x = \dfrac{-3}{2}[/tex]

Write the equation of the circle with center (0, 0) and (3, 6) a point on the circle.

Answers

Answer:

Step-by-step explanation:

We will use the standard form of a circle to solve for the radius and then fill it back in. h is 0, k is 0, x is 3, and y is 6:

[tex](3-0)^2+(6-0)^2=r^2[/tex] and

[tex]3^2+6^2=r^2[/tex] and

[tex]9+36=r^2[/tex]

Therefore, r-squared is 45, so the circle's equation in standard form is

[tex](x-0)^2+(y-0)^2=45[/tex] or more simply:

[tex]x^2+y^2=45[/tex]

what is the missing exponent?

17 / 17^4 = 17^8​

Answers

Answer:

The missing exponent is 12.

Step-by-step explanation:

Whenever you divide same-base exponents, you keep the base numbers the same and subtract the exponents.

The only number subtracted by 4 that would give you 8 is 12.

Or, if the numbers are larger, it is must easier to add the exponent in the answer to the number in the equation.

For example,

[tex]17^4+17^8=17^1^2[/tex]

Therefore, the missing exponent is 12.

Because:  [tex]17^1^2/17^4=17^8[/tex]
