please help!!
13 points & brainliest :)

Step-by-step explanation:

[tex]3 < x \geqslant 5[/tex]

Answer:

  B, C

Step-by-step explanation:

Since y=0, you are looking for equations such that 10 times the coefficient of x is the constant in the equation.

  a) 5·10 ≠ 15

  b) 2·10 = 20 . . . . select this one

  c) 10 = 10 . . . . select this one

  d) 3·10 ≠ 13

  e) 4·10 ≠ 20

  f) 6·10 ≠ 50

Hey there!

4(x + 3)

= 4(1x + 3)

DISTRIBUTE 4 WITHIN the PARENTHESES

= 4(1x) + 4(3)

= 4(x) + 4(3)

= 4x + 12

Therefore, your answer is:

Option B. 4x + 12

Good luck on your assignment & enjoy your day!

Answer:

20 units

Step-by-step explanation:

there is a theroem when a tangent and secant intersect outside a circle

as per it

CU*DU = GU^2

7.2*DU = 12*12=144

DU = 20 units

Answer:

(3,2)

Step-by-step explanation:

2x-4=y

2y+3x=13

We substitute the y in. They already gave us the equation 2x-4=y simplified so you would just plug this into the other equation

2(2x-4) +3x=13 : *distribute*

4x-8+3x=13 :  *combine like terms*

7x-8=13  * add the 8 to the other side*

7x=21 *divide*

x=3

So  the y=2x-4 is what we added in the place of the y to subtract it and solve for x. The second step would be solving for y. So now that we have our answer, 3  we plug it into the other equation preferably.

2(3)-4 =y : 6-4=y : 2=y

We can check our answer by pugging both x and y into both equations to make sure they are right. The statement should be true.

2x-4=y         2(3)-4=(2)    2=2

2y+3x=13    2(2)+3(3)=13    13=13

Use your calculator to the square root of 125.

The answer is 11.180...... and so on. But we just leave it as 11. Therefore, 11 and 11 are equal. That's the answer to your question.

C

Step-by-step explanation:

Answer: 173 because she wrote two checks was nto given two checks so you subtract :)

Step-by-step explanation:

[tex]\qquad \textit{Amount for Exponential Decay} \\\\ A=P(1 - r)^t\qquad \begin{cases} A=\textit{current amount}\dotfill &\stackrel{40\%~of~P}{0.4P~~~~}\\ P=\textit{initial amount}\dotfill &P\\ r=rate\to 22.5\%\to \frac{22.5}{100}\dotfill &0.225\\ t=\textit{elapsed time}\\ \end{cases} \\\\\\ 0.4P=P(1-0.225)^t\implies \cfrac{0.4P}{P}=(1-0.225)^t\implies 0.4=0.775^t[/tex]

[tex]\log(0.4)=\log(0.775^t)\implies \log(0.4)=t\log(0.775) \\\\\\ \cfrac{\log(0.4)}{\log(0.775)}=t\implies \stackrel{\textit{about 3years, 215days and 8hrs}}{3.59\approx t}[/tex]

so at that time the value is 40% of its original value, I guess is less than that a minute or an hour later.

Answer:

18√(2y)

Step-by-step explanation:

10√(2y) +  5√(2y) + 3√(2y) =

= 18√(2y)

= 18√(2y)

Answer:

50,646

Step-by-step explanation:

Jim would have saved 50,646 in 4 years

1 Year= 12.6615

12.6615 x 4=50,646

Jim will have $5,149,010 in 4 years.

Simple interest is a method for figuring out how much interest was paid on a sum of money during a specific time period at a specific rate. Simple interest has a constant principle amount. Simple interest is a clear-cut and simple method for computing financial interest.

We have,

P = $84,410.

R= 15%

T = 4 years

Using Simple Interest

SI = (P x R x T) / 100

SI = (84410 x 15 x 4)/100

SI = 5,064,000

So, the amount is

= 84,410 + 5,064,000

= 5,149,010

Step-by-step explanation:

Answer:78

Step-by-step explanation:

Answer:

Measure of each angle is 71 and 19 degrees.

Step-by-step explanation:

Let's the angle  be "n"

Complementary angle = 90 °

n- (90-x) = 52

n - 90+ n = 52

Combine like terms

n - 90+ n = 52

2n-90=52

Add 90 to both sides of the equation

2n-90+90=52+90

simplify

2n = 142

Divide both sides of the equation by the same term

2n/2 = 142/2

Simplify

n = 71

2n = 142

Measure of each angle

1st = 71

2nd = 90-71 = 19
