Inequality Notation: x≥-4

Step-by-step explanation:

An inequality is a mathematical statement that compares two expressions using the ideas of greater than or less than.

Solve 5x+2≥−18.

Subtract 2 from both sides.

5x+2−2≥−18−2

5x≥−20

Divide both sides by 5.

[tex]\frac{5x}{5}[/tex]

x≥-4

Answer:

14 miles

Answer:

90° is correct answer. :)

Answer:

5 meters

Step-by-step explanation:

The values given, 3 and 4, are the legs a and b. The hypotenuse is the third and longest side, c.

To find the length of the hypotenuse, use the formula a² + b² = c².

Substitute our values for a and b and solve.

a² + b² = c²

3² + 4² = c²

9 + 16 = c²

25 = c²

√25 = √c²

5 = c

The hypotenuse is 5 meters long.

Answer:

confidence interval = ( -0.38 , 0.08 )

Step-by-step explanation:

Given data :

n1 = 55 , n2 = 60 ,

Let P1 ( proportion of SUV sales at store A ) = 30 / 55 = 0.55

P2 ( sample proportion of SUV sales at store B ) = 42/60 = 0.70

The Z-value at 99% confidence Interval = 2.58

Determine the 99% confidence interval for difference in proportion

================================

Explanation:

Arcs JK and KL form a semicircle, so they add to 180 degrees

(arcJK) + (arcKL) = 180

(5x+23) + (17x-41) = 180

22x-18 = 180

22x = 180+18

22x = 198

x = 198/22

x = 9

Then you'll use this x value to find arc JK and arc KL

arc JK = 5x+23 = 5*9+23 = 68

arc KL = 17x - 41 = 17*9-41 = 112

Since central angles MNJ and KNL are vertical angles, this means minor arcs MJ and KL are congruent arcs. So arc MJ is also 112 degrees

Arc LMK is basically nearly everything of the full circle, but we exclude out the portion from L to K (the shorter distance)

arc LMK = (full circle) - (measure of minor arc LK)

arc LMK = 360 - 112

arc LMK = 248

Answer:

44.1

Step-by-step explanation:

Cosine = Adjacent over Hypotenuse

Adjacent of ∠T = 28 and hypotenuse = 39

Which means that  [tex]cos(x)=\frac{28}{39}[/tex]

Now we solve for x

To get rid of the "cos" we take the inverse of cos ( which is [tex]cos^-^1[/tex] ) and apply it to each side

[tex]cos^-^1((cos)x) = x\\cos^-^1(\frac{28}{39} )=44.11461855[/tex]

We're left with x = 44.11461855

Our last step is to round to the nearest tenth and we get that the answer is 44.1

Answer:

c.    {....., -8, -7, -6}

Step-by-step explanation:

x - 9 < -15

x < -6

The value of x must be less than -6. From the set of values, the values less than -6 are -7, -8, -9.... The correct sets is {......,-8, -7, -6}

Given the inequality expression

x - 9 < -15

Add 9 to both sides

x - 9 + 9< -15 + 9

x + 0 < -15 + 9

x < -15 + 9

x < -6

Hence the value of x must be less than -6. From the set of values, the values less than -6 are -7, -8, -9.... The correct sets are {......,-8, -7, -6}

Answer:

Step-by-step explanation:

we can't answer an incomplete question sorry try again and maybe then

If the interest for 3 months is $260, then the total interest for the year is 4 times $260 or $1040.

Let x = amount invested at one of the rates, say 6%. This leaves the rest of the $16,000 or (16000-x) to be invested at the other rate, at 8%.

The equation is basically that the interest earned for 1 year at 6% plus the interest earned for the year at 8% is equal to the total interest for the year, or $1040.

.06x + .08(16000-x) = 1040

.06x + .08(16000) - .08x = 1040

-.02x + 1280 = 1040

Subtract 1280 from each side:

-.02x = 1040 - 1280

-.02x = -240

To solve for x, divide both sides by -.02, remembering that a negative divided by a negative is a negative.

x = 240/.02

Either divide with a calculator, or multiply numerator and denominator by 100 to eliminate the decimal.

x = 24000/2 = $12000 at 6%

16000-x = 16000-12000 = $4000 at 8%

43.0 square centimeters of paper are required to make each wristband.

The curved surface of a cylinder is equal to a rectangle whose length is

2[tex]\pi[/tex]r and whose width is h.

The area of the curved surface = [tex]\pi dh[/tex].

Given

Height of wrist band =  1.8 cm

Diameter of wrist band =7.5 cm

Wrist band is a cylinder

Area of curved surface

Under a counterclockwise rotation about the origin of 90°

a point (x, y ) → (- y, x ) , then

A (2, - 2 ) → A' (2, 2 )

B (4, - 1 ) → B' (1, 4 )

C (4, - 3 ) → C' (3, 4 )

D (2, - 4 ) → D' (4, 2 )

Answer:

Step-by-step explanation:

When we transpose - 4x to the LHS then it becomes positive i.e +4x

Now we transpose 28 to the RHS then it becomes negative i.e - 28

So the first step you have to is,

4x = - 12 - 28

The angle m∠CBE between the intersection of the chord and tangent line is equal to 41°

To calculate for the angle between the intersection of a chord and a tangent we need to know the measure of the intercepted arc, and then divide it by 2 to get the angle.

If the measure of the arc CAB is given to be equal to 278°, then the measure of intercepted arc BC is calculated as:

arc BC = 360 - 278

arc BC = 82°

angle CBE = 82°/2

m∠CBE = 41°

Therefore, the angle m∠CBE between the intersection of the chord and tangent line is equal to 41°

Bill paid = $ 10

Cost of binder = $ 1.38

Cost of pack of pencils = $ 2.05

Cost of box of erasers = $ 3.88

Total cost of the school supplies = $ 1.38 + $ 2.05 + $ 3.88 = $ 7.31

The amount of change Judy received = $ 10 - $ 7.31 = $ 2.69

[tex]y=-6x+7[/tex]

Step-by-step explanation:

Hi there!

What we need to know:

1) Determine the slope (m)

[tex]6x+y=6[/tex]

Rewrite this in slope-intercept form (to help us find the slope)

Subtract 6x from both sides

[tex]6x+y-6x=-6x+6\\y=-6x+6[/tex]

Now, we can identify clearly that the slope of this line is -6. Because parallel lines always have the same slopes, -6 will therefore be the slope of the line we're solving for. Plug this into [tex]y=mx+b[/tex]:

[tex]y=-6x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=-6x+b[/tex]

Plug in the given point (2,−5) and isolate b

[tex]-5=-6(2)+b\\-5=-12+b[/tex]

Add 12 to both sides

[tex]-5+12=-12+b+12\\7=b[/tex]

Therefore, the y-intercept is 7. Plug this back into [tex]y=-6x+b[/tex]:

[tex]y=-6x+7[/tex]

Answer:

Step-by-step explanation:

3/15 simplifies to 1/5

Answer:

Yes

Step-by-step explanation:

For the first equation all we need to do is distribute 6 to 3x and 5y. 6*3x = 18x and 6*5y = 30y. For the first equation, it will be: 18x + 30y.

The next equation seems hard but it's simple. First you can easily add, 4x and 6x. That will equal 10x. Then from there distribute 2 to 4x and 2y, so do the same thing as before. 2*4x = 8x and 2*2y = 4y. So now our equation looks like this: 10x + 15y + 8x + 4y + 11y. Now all you need to do is add the x's together and the y's together. 10x + 8x = 18x and 15y + 4y + 11y = 30y. Now we have 18x + 30y. Looks the same, and that is true.

Both equations equal 18x + 30y, so therefore the answer is yes or true.

Answer:

Center= (-9,6) Radius=5

Step-by-step explanation:

correct answer:

( x + 9 ) ² + ( y - 6 ) ² = 25

center = ( -9, 6 )

radius = 5

equations:

we know from the given equation that the center would be (-9, 6) because we have to plug into the equation; ( x – h ) ² + ( y – k ) ² = radius²

how to find the center coordinates:

if youre confused on how we got the -9, by using the negative addition rules:

x - (-9) we can simplify that to ( x + 9 ) like shown above so that how we got -9. It's a little easier to find the 6 because its just x - 6 so we dont have to simplify anything its just 6.

how to find the radius:

the radius is a little more difficult to find, but, since we are given 25, we can just type the square root of 25 (√25) which would be 5!

thats it!! hope this helps<3
