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:

The inequality matches the graph is 2n + 5 ≤ 7 ⇒ A

Step-by-step explanation:

Let us solve the question

From the given graph

∵ The arrow starts from 1 and pointed to the left (negative part)

∵ The starting point of the arrow is bold

∴ The sign of the inequality is ≤ (smaller than or equal)

→ That means the solution of the inequality is all the numbers ≤ 1

∴ The solution of the inequality is n ≤ 1

→ Look at the choices and find which one has the sign ≤ and check if

  it will give the same solution or not

∵ The inequality is 2n + 5 ≤ 7

→ Subtract 5 from both sides

∴ 2n + 5 - 5 ≤ 7 - 5

∴ 2n ≤ 2

→ Divide both sides by 2

∴ n ≤ 1

∵ The inequality gives the same solution of the given graph

∴ The inequality matches the graph is 2n + 5 ≤ 7

Answer: b

Step-by-step explanation:

B because 10+1 is 11

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:

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:

y = -x/3 + 6

General Formulas and Concepts:

Pre-Algebra

Algebra I

Standard Form: Ax + By = C

Slope-Intercept Form: y = mx + b

Step-by-step explanation:

Step 1: Define

Standard Form:   x + 3y = 18

Step 2: Rewrite

Find slope-intercept form

Answer:

y=-3x+6

Step-by-step explanation:

slope int. form is y=mx+b

want to get y by itself, so subtract 1x

so you are left with 3y=-1x+18

then divide 3

left with y=-1/3x+6

simplified is y=-3x+6

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

Answer:

6

Step-by-step explanation:

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

7y + 5 = 12y - 15

7y + 20 = 12y

20 = 5

Answer:False.

Step-by-step explanation:Any two right triangles, similar or not, must have one pair of congruent angles, the right angles. If one pair of acute angles angles is congruent, then by AA Similarity, the triangles are similar.

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.

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

Interpretation of axes and scales:

The horizontal axis (x-axis): There is time in seconds on the horizontal axis

Scale: 1 unit in the x-axis = 1 second

The vertical axis (y-axis): There is the distance in feet which is the height of the elevator from the ground on the horizontal axis

Scale: 1 unit in the y-axis = 20 feet

Interpretation of the origin:

The coordinate is represented by the point (0,0) in the graph. This means at time = 0 the height of the elevator =0, i.e the elevator is on the ground at the starting time.

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]

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
