Joe piad $5 for a burger. He has more than $25 left. How much money did he have before buying the burger?
Answer:
More than 30 dollars
Step-by-step explanation:
This situation can be described with the inequality:
x - 5 > 25
1. Add 5 to both sides
2. X > 30
A system of inequalities is shown.
The graph shows a dashed upward opening parabola with a vertex at negative 2 comma negative 6, with shading inside the parabola. It also shows a dashed line passing through the points negative 3 comma negative 5 and 0 comma 4, with shading below the line.
Which system is represented in the graph?
The required system hence becomes
3x-y+4>0,
y + 6 > (x + 2)²
When the symbols “>”, “<”, “≥”, “≤”, are used to connect two real numbers or algebraic expressions, that relationship is known as an inequality.
The Graph is given below of the given problem statement.
Observe that the parabola y=x² has vertex at (0,0) we can shift the vertex to (-2,-6) to get the parabola
y + 6 = (x + 2)²
And the inequality is
y + 6 > (x + 2)²
Hence, this parabola is as required by the problem.
And the line passing through (-3,-5) and (0,4) is
[tex]\frac{\left(y-4\right)}{\left(-5-4\right)}=\frac{\left(x\right)}{-3}[/tex]
The required inequality hence becomes
3x-y+4>0

I’m very lost with this one can anyone answer this for me please
Answer:
So let start with 1/4 simplest form of that would be 9/4 and for 11/24 simplest would be just that so now we got 11/24 - 9/4 = 1/72
Step-by-step explanation:
11/24
4/9
now we do 11 x 9 equals 99 so now 4 x 24 = 96
now we take the two new denominators2 24 and 9
and we do 24 x 9 = 216 so now we got
99/216
96/216
now 99 - 96 is 3 so we got a new fraction
3/216 now we just simplify that so we get 1/72

Translate the circles so they share a common center point, and dilate circle Y by a scale factor of 4.
Translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle Y by a scale factor of 4.
Translate the circles so they share a common center point, and dilate circle Y by a scale factor of 3.
Translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle Y by a scale factor of 3.
The steps needed is :Translate the circles so they share a common center point, and dilate circle Y by a scale factor of 3.
What is dilation?Dilation is a transformation, which is used to resize the object.
As the radius of big circle is 6 then the dilation should be scale factor 3.
As well as they should share the same center.
The radius of circle y being 2, has to increase by 3 times the value to equal the radius of circle x, and hence has to dilate by a scale factor of 3 as to match circle x,

You are buying a used car which costs $10,200. You plan to sell the car after keeping it for 5 years. Research shows that this car will lose value at a rate of 8% per year. How much will the car be worth after 5 years?
Answer:
$6,722.63
Step-by-step explanation:
Now: $10,200
In 1 year: 0.92 × $10,200 = $9,384
In 2 years: 0.92 × $9,384 = $8,633.28
In 3 years: 0.92 × $8,633.28 = $7,942.6176
In 4 years: 0.92 × $7,942.6176 = $7,307.208192
In 5 years: 0.92 × $7,307.208192 = $6,722.63
Answer: $6,722.63
Answer:
$6,722.63
Step-by-step explanation:
Using this formula A=P(1-d/100)^n where
A = Amount
P = Principal
d = percent
n = number of year
A=P(1-d/100)^n
A = 10,200(1-8/100)⁵
A = 10,200(1-0.08)⁵
A = 10,200(0.92)⁵
A = 10,200(0.6591)
A= $6,722.63

Answer: [tex]230^{\circ[/tex]
Step-by-step explanation:
For convenience, I labeled some points as shown in the attached picture.
Also, I assume [tex]\overline{AB}[/tex] and [tex]\overline{BC}[/tex] are tangents to the circle.
[tex]\overline{BO} \cong \overline{BO}[/tex] (reflexive property)[tex]\overline{AB} \cong \overline{BC}[/tex] (tangents drawn from a common external point are congruent)[tex]\angle BAO \cong \angle BCO[/tex] (right angles are congruent)Therefore, we know [tex]\triangle ABO \cong \triangle CBO[/tex] by HL.
Thus, by CPCTC,
[tex]\angle AOB \cong \angle BOC \implies m\angle BOC=65^{\circ}\\\\\implies m\angle AOC=130^{\circ}[/tex]
This means the measure of minor arc AC is [tex]130^{\circ}[/tex], and thus [tex]b=360^{\circ}-130^{\circ}=\boxed{230^{\circ}}[/tex]

Hence the probability of no dandelions in an area of 1 m² is P(X = 0), hence:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
[tex]P(X = 0) = \frac{e^{-10.6}(10.6)^{0}}{(0)!} = e^{-10.6}[/tex]
The probability of at least one dandelion is:
[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - e^{-10.6}[/tex]
The probability of at most two dandelions is:
[tex]P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2)[/tex]
Then:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
[tex]P(X = 0) = \frac{e^{-10.6}(10.6)^{0}}{(0)!} = e^{-10.6}[/tex]
[tex]P(X = 1) = \frac{e^{-10.6}(10.6)^{1}}{(1)!} = 10.6e^{-10.6}[/tex]

You enter a room. 2 dogs, 4 horses, 1 giraffe, and a duck are lying on the bed. 3 chickens are flying over a chair.
How many legs are on the ground?
Answer:
28
Step-by-step explanation:
1 dog = 4 legs, 2 dogs = 8 legs
1 horse = 4 legs, 4 horses = 16 legs
1 giraffe = 4 legs.
So we need to add "2 dogs = 8 legs", "4 horses = 16 legs", and 1 giraffe = 4 legs.
(8 + 16 + 4)

Which point corresponds to the real zero of the graph of y = log2 (x + 2) - 1?
Answer:
(0, 0)
Step-by-step explanation:
Ok so you have the equation: [tex]y = log_2{(x+2)}-1[/tex]. To find the zero you simply set the y equal to zero and then solve for x
[tex]0 = log_2{(x+2)}-1[/tex]
Add 1 to both sides
[tex]1 = log_2{x+2}[/tex]
Rewrite the equation in exponential form:
[tex]2^1=x+2[/tex]
Subtract 2 from both sides
[tex]0 = x[/tex]
So the zero of the function is at the origin (0, 0)
