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

In this picture B and Fare
midpoints.
A
B
5x - 4
23
F
E
x=[ ? ]
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:
I think 3,9, and 15
Step-by-step explanation:
find the value of x (3/5)^x(5/3)^2x=125/27
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.

Hyan has saved $300 more than two-thirds of the cost of the down
payment on a car. If he has $1240 saved, how much is the down payment?
algebra problem
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
its all in the picture

Answer:
f(- 3) = 6
Step-by-step explanation:
f(- 3) means what is the value of f(x) when x = - 3
Locate x = - 3 on the x- axis
Then go vertically up to meet the graph at (- 3, 6 )
The value of f(- 3) is therefore 6, that is
f(- 3) = 6
Pls help solve this question
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.

I need that r d d d d d. D d d d d d d. D
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.

D is not a function.

Diego pours 6.8 ounces of water from a full bottle. He estimates that he poured out 20% of the water in the bottle. About how much water was in the full bottle? Diego pours out 25% of the remaining water. About how many ounces did he pour the second time? Explain your reasoning.
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

5+(−3)(6x−5) using distributive property
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

Triangle GHI with vertices G(4, 1), H(5, -4), and I(2, -8) REFLECTED over the line y = x.
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]

An angle is 58º less than its supplement. What is the measure of the angle?
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

two right triangles that are not similar can still have a pair of congruent acute angles.
A. True
B. False
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.
what is 1x+3y=18 in slope intercept form
Answer:
y = -x/3 + 6
General Formulas and Concepts:
Pre-Algebra
Equality PropertiesAlgebra I
Standard Form: Ax + By = C
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStep-by-step explanation:
Step 1: Define
Standard Form: x + 3y = 18
Step 2: Rewrite
Find slope-intercept form
Subtract x on both sides: 3y = -x + 18Divide 3 on both sides: y = -x/3 + 6Answer:
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
