what is % of $2 = $1
Answer:
50%
Step-by-step explanation:
Let [tex]x[/tex] be equal to the decimal when multiplied by 2 equals 1
[tex]2x=1[/tex]
Divide both sides by 2
[tex]\frac{2x}{2} =\frac{1}{2} \\x=0.5[/tex]
Multiply the decimal by 100 to get a percent
0.5×100=50%

What is the value of y in the equation 2(3y − 6) = 0
Answer:
[tex]y = 2[/tex]
Step-by-step explanation:
1) Divide both sides by 2.
[tex]3y - 6 = 0[/tex]
2) Add 6 to both sides.
[tex]3y = 6[/tex]
3) Divide both sides by 3.
[tex]y = \frac{6}{3} [/tex]
4) Simplify 6/3 to 2.
[tex]y = 2[/tex]
Therefor, the answer is y = 2.
Find the value of x and check the solution.
5 + 4x = -11
Answer:
x=-4
Step-by-step explanation:
5+4x=-11
4x=-11-5
4x=-16
x=-16/4
x=-4
5+4(-4)=-11
5-16=-11
-11=-11
Answer:
x = -4
Step-by-step explanation:
5 + 4x = -11
4x = -11 - 5
4x = -16 (Divide 4 both sides)
x = -4
5 + 4x = -11
5 + 4(-4) = -11
5 - 16 = -11
-11 = -11
If using the method of completing the square to solve the quadratic equation
x2 + 13x -3 = 0, which number would have to be added to "complete the
square"?
Answer:
Step-by-step explanation:
The term added which completes the square is half of the linear coefficient squared. In a quadratic ax^2+bx+c, b is the linear coefficient, so in this case the added term would be
(13/2)^2=169/4=42.25
The term 13/2 is added to complete the square.
What is a quadratic equation?
A quadratic equation is a polynomial which has the highest degree equal to two. It is a second-degree equation of the form ax² + bx + c = 0, where a, b, are the coefficients, c is the constant term, and x is the variable.
For the given situation,
The quadratic equation is x^2 + 13x -3 = 0.
This is not the perfect square term. So we can solve this by using the completing the square method.
⇒ [tex]x^{2} +13x-3=0[/tex]
⇒ [tex]x^{2} +13x=3[/tex]
⇒ [tex]x^{2} +13x + (\frac{13}{2})^{2} =3+(\frac{13}{2})^{2}[/tex]
⇒ [tex](x+\frac{13}{2} )^{2} =3+\frac{169}{4}[/tex]
⇒ [tex](x+\frac{13}{2} )^{2} =\frac{181}{4}[/tex]
⇒ [tex]\sqrt{ (x+\frac{13}{2} )}^{2} =\sqrt{\frac{181}{4}}[/tex]
⇒ [tex](x+\frac{13}{2})[/tex] = ± [tex]\frac{\sqrt{181} }{2}[/tex]
Hence we can conclude that the term 13/2 is added to complete the square.

HEY CAN ANYONE PLS ANSWER DIS MATH PROBLEM!!!!
Answer: y = (-1/2)x + 8.5
Step-by-step explanation:
A line perpendicular would have a slope that is the negative reciprocal of the given equation.
In this case, the slope is 2, so the perpendicular equation's slope would be -1/2.
We plug in (1, 8) to find b, or the y intercept.
8 = (-1/2)(1) + b
b = 8.5
So the equation would be:
y = (-1/2)x + 8.5

The height of a sunflower can be modeled by the expression H (1.02)t where t represents the number of years since it was planted and H represents the height when the sunflower was planted. What is the yearly growth of the sunflower?
Answer:
2%
Step-by-step explanation:
Giveb the model expression :
H = (1.02)^t
General relation:
H = (1 + rate)^t
Rate = yearly growth rate of sunflower
1 + rate = 1.02
Rate = 1.02 - 1
Rate = 0.02
Hence yearly growth rate of sunflower is :
0.02 * 100%
= 2%
2% growth per year.
