should be the answer

Answer:

a.[tex]-7 < x < 7[/tex]
b.[tex]-12 < x < 6[/tex]
c. Two answers are: y < -3 or y > 19
d. Two answers are x ≤ -17/3 or x ≥ 19/3
e. -4 ≤ y ≤ 5/2

Step-by-step explanation:

Given the following questions:

Question one:

[tex]|x| < 7[/tex]
x is less than 7
[tex]=-7 < x < 7[/tex]

Question two:

[tex]|x+3| < 9[/tex]
[tex]x+3 > -9[/tex]
[tex]3-3=0[/tex]
[tex]-9+-3=-12[/tex]
[tex]x > -12[/tex]

[tex]x+3 < 9[/tex]
[tex]3-3=0[/tex]
[tex]9-3=6[/tex]
[tex]x < 6[/tex]
x is greater than -12, while less than 6
[tex]-12 < x < 6[/tex]

Question three:

[tex]|y-8| > 11[/tex]
[tex]y-8 < -11[/tex]

Two answers are: y < -3 or y > 19

Question four:

|3x - 1| ≥ 18
3x - 1 ≤ -18
-1 + 1 = 0
-18 + 1 = -17
3x ≤ -17
x ≤ -17/3

3x - 1 ≥ 18
-1 + 1 = 0
18 + 1 = 19
3x ≥ 19
x ≥ 19/3
Two answers are: x ≤ -17/3 or x ≥ 19/3

Question five:

|4y + 3| ≤ 13
|4y + 3| ≤ 13 = -13 ≤ 4y + 3 ≤ 13
-13 ≤ 4y + 3 ≤ 13
4y + 3 ≥ -13
3 - 3 = 0
-13 + - 3 = -16
4y ≥ -16
4 ÷ - 16 = -4
y ≥ -4

4y + 3 ≤ 13
3 + -3 = 0
13 - 3 = 10
4y ≤ 10 = 10/4 ÷ 2 = 5/2
y ≤ 5/2
-4 ≤ y ≤ 5/2

Hope this helps.

Answer:

4/5 = x

0.8 = x

Step-by-step explanation:

2^2 - 5x = 0

first, we must solve for exponents, as per PEMDAS.

4 - 5x = 0

4 = 5x

4/5 = x

or x = 0.8

Answer:

x = 0

x = -5/2

Step-by-step explanation:

2x squared + 5 = 0

x (2x + 5) = 0

therefore...

x = 0

and

2x + 5 = 0

2x = - 5

x = -5/2

Got it right Edge 2020

Answer:

∠ ABC = 81° , ∠ FEC = 90°

Step-by-step explanation:

Since AB ≅ BC then Δ ABC is isosceles.

The median BE is therefore

The angle bisector of ∠ ABC and

BE bisects AC at right angles.

Thus

∠ ABE = ∠ CBE = 40° 30' , then

∠ ABC = 2 × 40° 30' = 81°

Since BE is perpendicular to AC then

∠ FEC = 90°

The correlation that exists between the temperature and the number of fruits sold is positive but is almost negligible.

The correlation coefficient helps us to know how strong is the relation between two variables. Its value is always between +1 to -1, where, the numerical value shows how strong is the relation between them and, the '+' or '-' sign shows whether the relationship is positive or negative.

A result of zero indicates no relationship at all, therefore, independent variable.

We know that the correlation coefficient is given by the formula,

[tex]r =\dfrac{\sum\left(x_{i}-\bar{x}\right)\left(y_{i}-\bar{y}\right)}{\sqrt{\sum\left(x_{i}-\bar{x}\right)^{2} \sum\left(y_{i}-\bar{y}\right)^{2}}}[/tex]

r = correlation coefficient

[tex]x_{i}[/tex] = values of the x-variable in a sample

[tex]\bar{x}[/tex] = mean of the values of the x-variable

[tex]y_{i}[/tex] = values of the y-variable in a sample

[tex]\bar{y}[/tex] = mean of the values of the y-variable

Calculate the value of [tex](x_i-\bar{x})(y_i-\bar{y}),\ (x_i-\bar{x})^2,{ \rm and}\ (y_i-\bar{y})^2[/tex] each separately, and then find the sum of them as shown below, therefore, the formula can be written as,

[tex]r =\dfrac{571.5}{261.5\times 1566.833333}= 0.0014[/tex]

Hence, the correlation that exists between the temperature and the number of fruits sold is positive but is almost negligible.

Answer:

The volume of the balloon when it is fully cooled by my refrigerator is

2.75liters

Step-by-step explanation:

we are expected to apply Charles law in this problem and solve for the final volume V2

the expression for Charles law is give as

V1/T1=V2/T2

given data

V1, first volume = 0.5 liters

V2, second volume =?

T1, first temperature = 40 ◦Celsius.

T2, second temperature =220 °C

applying the formula we have

0.5/40=V2/220

V2=(0.5*220)*40

V2=110/40

V2=2.75liters

Answer:

-2

Step-by-step explanation:

The value of c is -4, therefore the additive inverse should be added to get the answer 0

The roots of the quadratic equation x² – 2x + c = 0 are a and –b. Then the value of c is a² – 2a.

It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

For which values of c does the quadratic equation

x² – 2x + c = 0 ...1

Two roots of opposite signs

Let the two roots of the opposite signs be a and –b

x = a, –b

Then we have factorized the equation,

(x + b)(x – a) = 0

On solving, we have

x² + (b – a)x – ab = 0 ...2

In comparing equation 2 with equation 1, we have

⇒  b – a = –2

⇒ b = –2 + a

and

⇒ c = a(a – 2) = a² – 2a

Flipping the bulbs is an illustration of sequence and patterns

17 bulbs would remain on.

The sequence of turning the bulbs off and on, would change the state of the bulbs until the 300th process.

While changing the state of the bulbs, the bulb at the perfect square positions would remain on.

There are 17 perfect square numbers between 1 and 300 (inclusive)

Hence, 17 bulbs would remain on.

Answer:

The y intercept of Function A is the same as the y intercept as function B

Step-by-step explanation:

they both have a y intercept of 2

y = mx + b

b is the y intercept

in the table all you have to look for is when x is 0

I know it is probably to late for your answer but if you are on Solving and Reasoning with Complex Numbers: Tutorial in Edmentum, then the answer for part D on the first lesson activity is this word for word.

This equation generalizes the patterns seen in part D, where a and b represent real numbers:

(a + bi)(a − bi) = a2 + b2.

Hope this helps good luck

Answer:

for the 1st one, m=10 and b=2 because from the word problem it says it starts at 10 which would be 10 on the y axis being where the line would pass through and spending 2 a week would be the slope because he is losing 2 per week its a negative slope so y=10x-2.

for the second one m=48 and b=44 its just like the last one but with different numbers but comment if you want me to explain it but the answer is y=48x-44.

Answer:

Option b - $163.07

Step-by-step explanation:

Given :  A loan of $7,500 with an 11% interest rate compounded monthly over a period of 5 years.

To find : Monthly payment

Solution : Formula to find monthly payment

Monthly Payment = Amount / Discount factor

Discount factor

where ,

Amount = $7500

Rate= 11%=0.11

Time = 5 years

Now, put i and n in Discount factor ,

Monthly payment,

Therefore, Option b is correct monthly payment = $163.07

Answer:

The answer is $163.07

Step-by-step explanation:

To find the monthly payment:

[tex]i = \frac{0.11}{12} = 0.0091[/tex]

Time = 5 years

5 x 12 = 60

Discount factor

[tex]D = \frac{1-(1 + i) -^{n}}i[/tex]

[tex]D = \frac{1 - (1+ 0.009)-^{60} }{0.009} \\[/tex]

[tex]D = \frac{0.421}{0.009} = 46.77[/tex]

Monthly payment

[tex]\frac{7500}{46.77} = $163.07[/tex]

Answer:

The last one

Step-by-step explanation:

K so first look at y intercept which is +5, so we eliminate A and C, then the graph opens up so the b in ax+bx+c has to be positive which is D

the point ( 0 ; 5 ) in on the curve

so f(0) = 5

choice between :

x² - 2x + 5 or x² + 2x + 5 then :

we have the point (1 ; 4)

with x² - 2x + 5

f(1) = 1² - 2*1 + 5 = 1 - 2 + 5 = 4

so it's correct

=> x² - 2x + 5 is the right one
