Answer:

10

Step-by-step explanation:

In triangle ACE, B and F are mid points of sides CA and CE respectively.

Therefore, BF is the mid segment of triangle ACE.

By Mid-segment formula:

AE =2BF

5x - 4 =2*23

5x - 4 = 46

5x = 46+4

5x = 50

x = 50/5

x = 10

Answer:

Step-by-step explanation:

A dependent variable in an expression is one whose value can be determined only when the value of other variable (i.e independent) is known.

A. The cost at the fitness center depends on the number of months (x).

The cost is the dependent variable, and number of months (x) is the independent variable.

f(x) = 100 + 40x

Example, the cost paid for 12 months can be determined as;

f(12) = 100 + 40(12)

       = 100 + 480

       = 580

Thus, $580 would be paid for 12 months at the fitness center.

B. The lettuce is sold at $1.69 per pound. The cost depends on the number of pounds of lettuce bought.

The cost is the dependent variable, while the number of pounds of lettuce (x) bought is the independent variable.

So that;

f(x) = 1.69x

The cost of 10 pounds of lettuce can be determined as;

f(x) = 1.69(10)

     = 16.9

Thus, the cost of 10 lb of lettuce is $16.90.

Answer:

6

Step-by-step explanation:

5y + 2 +2y + 3 = 12 - 15

7y + 5 = 12y - 15

7y + 20 = 12y

20 = 5

Step-by-step explanation:

Answer:

J=18.5

K= 16

L= 17

M= 18

W= 625

X=645

Y= 729

Z= 1000

Answer:

C: 108 Feet

Step-by-step explanation:

You just plug 3 in for t.

h(t) = -18(3)^2 + 18(3) + 216 = 0

-18(9) + 54 + 216 = 0

-162 + 54 + 216 = 0

-108 + 216 = 0

-108 + 216 = 108

So I believe I am correct.

Answer:

3 I think forgive me if im wrong.

Step-by-step explanation:

Answer:

x= -1.8

Step-by-step explanation:

5+(-3)(6x-5)

the -3 goes into the 6x and -5

5+(-18x)+15

switch so like terms are together

5+(-5) these cancel out leaving you with

-18x+15-5

combine like terms

-18x+10

divide both sides by -18

x=-1.8

Answer:

18.5 is your answer.

Step-by-step explanation:

Divide the area by 11.9 and you get 18.5

Answer:

C. (f - g)(x) = 3ˣ - 2x + 14

General Formulas and Concepts:

Pre-Algebra

Algebra I

Step-by-step explanation:

Step 1: Define

f(x) = 3ˣ + 10

g(x) = 2x - 4

(f - g)(x) is f(x) - g(x)

Step 2: Find (f - g)(x)

Answer:

$1410

Step-by-step explanation:

Hyan has $1240 saved, which is equal to 2/3 of the down-payment, plus an additional $300

$1240-$300= $940

$940 is equal to 2/3 of the payment, in other words, it's two 1/3 payments, so we can split $940 into two to see how much is equal to 1/3 of the payment.

$940/2= $470 = 1/3

Three 1/3 equal 1 whole so we multiply $470 by 3 to find the amount of the whole payment

$470x3= $1410

Answer:

wow, it is.

1+2=3

2+3=5

3+4=7

4+5= 9

5+6= 11

6+7= 13

and so on.

Step-by-step explanation:

Answer:

i think it is 122 degrees, as the solution would be to subtract 58 from 180

Step-by-step explanation:

180-58=122

angle1 = x

angle2 = x - 58

given,

these are supplementary angles

Therefore,

(x) + (x - 58) = 180

x + x - 58 = 180

2x - 58 = 180

2x = 180 + 58

2x = 238

x = 238/2

x = 119

angle1 = 119

angle1 = 119angle2 = 61

Given:

The equation is

[tex]\left(\dfrac{3}{5}\right)^x\left(\dfrac{5}{3}\right)^{2x}=\dfrac{125}{27}[/tex]

To find:

The value of x.

Solution:

We have,

[tex]\left(\dfrac{3}{5}\right)^x\left(\dfrac{5}{3}\right)^{2x}=\dfrac{125}{27}[/tex]

[tex]\left(\dfrac{5}{3}\right)^{-x}\left(\dfrac{5}{3}\right)^{2x}=\dfrac{5\times 5\times 5}{3\times 3\times 3}[/tex]      [tex][\because \left(\dfrac{a}{b}\right)^{-m}=\left(\dfrac{b}{a}\right)^{m}][/tex]

[tex]\left(\dfrac{5}{3}\right)^{-x+2x}=\dfrac{5^3}{3^3}[/tex]          [tex][\because a^ma^n=a^{m+n}][/tex]

[tex]\left(\dfrac{5}{3}\right)^{x}=\left(\dfrac{5}{3}\right)^{3}[/tex]

On comparing the exponents, we get

[tex]x=3[/tex]

Therefore, the value of x is 3.

Answer:

F(x)>0 over the interval [tex](-\infty,-4)[/tex]

Step-by-step explanation:

If you pay close attention to the intervals given in the options, you can see that they are talking about the region to the left of either x=-3 or x=-4. The only statements that makes sense is that:

F(x)>0 over the interval [tex](-\infty,-4)[/tex]

When they say F(x)>0, they mean that the graph is above the x-axis and that will only happen when the x-values that are to the left of x=-4, therefore the answer would be:

F(x)>0 over the interval [tex](-\infty,-4)[/tex]

Answer:

D is not a function.

Step-by-step explanation:

The first option is a function because it makes up a straight line.  The second option is also a function because it is also known as y = -3/2x + 2 creating a slope function.  The third option is also a function because there is no more than one point for each x value.  The last option is not a function because the number 2 is going for 2 variables A and B and you can't have them with more than one so D is your answer.

Answer:

34 ounces were in the full bottle , The second time he poured about 7.48 ounces

Step-by-step explanation:

20 times 5 = 100 so,

6.8 times 5 = 34

PART 2

Diego poured out 20% wich is equal to 6.8 and if you subtract both pour's that he did you get 20.4. The you subtract that amount that he had already poured  from the total wich gives you 13.6 and 5% of 13.6 is 0.68. Add 0.68 and 6.8 to get 7.48

Answer:

[tex]G' = (1,4)[/tex]

[tex]H' = (-4,5)[/tex]

[tex]I = (-8,2)[/tex]

Step-by-step explanation:

Given

[tex]G = (4,1)[/tex]

[tex]H = (5,-4)[/tex]

[tex]I = (2,-8)[/tex]

Reflection: [tex]y = x[/tex]

Required

Determine the coordinates of G'H'I'

The following applies when a line A is reflected over [tex]y = x[/tex]

[tex]A = (x,y)[/tex]

[tex]A' = (y,x)[/tex]

i.e, we simply swap the positions of x and y

So, for:

[tex]G = (4,1)[/tex]

[tex]H = (5,-4)[/tex]

[tex]I = (2,-8)[/tex]

The reflections are:

[tex]G' = (1,4)[/tex]

[tex]H' = (-4,5)[/tex]

[tex]I = (-8,2)[/tex]
