Answer 1

Answer:

Choice 1

Choice 4

Choice 5

Step-by-step explanation:

For this one you just have to plug in the x in every equation and solve it. If the answer is true it's true, but if it's false it's false.

Let's solve each of these...

Number 1:

[tex]9-3x=0\\9-3(3)=0\\9-9=0\\0=0[/tex]

As you can see 0 does equal itself so this one is true.

Number 2:

[tex]3x+1=9\\3(3)+1=9\\9+1=9\\10\neq9[/tex]

10 does not equal 9 so this one would be false.

Number 3:

[tex]5x-7=1\\5(3)-7=1\\15-7=1\\8\neq1[/tex]

This one is also false.

Number 4:

[tex]2x+4=10\\2(3)+4=10\\6+4=10\\10=10[/tex]

This one is true.

Number 5:

[tex]\frac{x}{3}+5=6\\\frac{(3)}{3}+5=6\\1+5=6\\6=6[/tex]

This one is true.

Number 6:

[tex]\frac{9}{x}-1=4\\\frac{9}{(3)}-1=4\\3-1=4\\2\neq4[/tex]

This one is false.

Use the graph of f to estimate the local maximum and local minimum.
Local maximum: ∞ local minima: (-2,-4) and (2, -4)
Local maximum: (0,0); local minimum: (-2,-4)
No local maximum; local minimum: (2,-4)
Local maximum: (0,0); local minima: (-2,-4) and (2, -4)

Answers

Answer:

Option (4)

Step-by-step explanation:

From the graph attached,

A, B and C are the points based at the heights and valleys of the given curve.

y-coordinates of these points always decide, whether the point is a local maxima or local minima.

y-coordinate of A → -4

y-coordinate of B → 0

y-coordinate of C → -4

Ends of the curve are moving towards infinity, so the absolute maximum is not defined.

Local minimum → -4

Local maximum → 0

Therefore, point representing local maximum is B(0, 0).

Points representing local minimum are A(-2, -4) and C(2, -4).

Option (4) will be the correct option.

Answer:

The missing angle is 50 and x=6

Step-by-step explanation:

So if all three angles of a triangle add up to 180 degrees, you would simply subtract 180-70-60 to find the missing angle, and from there you put in the equation 8x+2=50, you would do a step by step process get the x by itself on one side. first subtract 2 from both sides to remove it from one, making the equation 8x=48 and than divide both sides by 8 to remove it from the x making the answer x=6. :3

Answer:

x=6

Step-by-step explanation:

Ok so to do this you need to know if you add up all the sides of a triangle [This is for triangles] you get 180 every time.

So you already have two given angels. 70 and 60.

Lets make it an equation.

70+60+8x+2=180

It looks long and hard but we can simplify this if we go ahead and add up all the common factors. In this case would be all the numbers with no variables.

132+8x=180

You don't add the 180 because its on the opposite side of the equation.

Now you need to get the variable alone. To do that you need to do the opposite operation. In this case, that would be subtraction

132(-132)+8x=180(-132)

8x=48

Divide the 8.

x=6

8(6)+2=50

plssss help me it’s really important!!!

Answers

Answer:

B

Step-by-step explanation:

Since ∠ E = ∠ F then the triangle is isosceles and DF = DE, that is

6x = x + 2y ( subtract x from both sides )

5x = 2y ( subtract 2y from both sides )

5x - 2y = 0 → (1)

and perimeter = 29, that is

6x x + 2y + 5x - y = 29 , simplifying

12x + y = 29 → (2)

Multiply (2) by 2

24x + 2y = 58 → (3)

Add (1) and (3) term by term to eliminate y, that is

29x = 58 ( divide both sides by 29 )

x = 2

Substitute x = 2 into (2) and evaluate for y

12(2) + y = 29

24 + y = 29 ( subtract 24 from both sides )

y = 5

Thus

FE = 5x - y = 5(2) - 5 = 10 - 5 = 5 → B

Answers

Answer:

Step-by-step explanation:

Here, we want to know at what time and day the ship arrive the second port

we simply need to add the time it left the first port and the amount of time the journey took

Mathematically, that will be;

22:45 + 7 1/4

1/4 is same as 60/4 = 15 minutes

So we have;

22:45 + 7:15

Hope it helps!

Answer:  [tex]\frac{8x^3}{27y^6}[/tex]

This is the fraction 8x^3 all over 27y^6

On a keyboard, we can write it as (8x^3)/(27y^6)

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

Explanation:

The exponent tells you how many copies of the base to multiply with itself.

We'll have three copies of [tex]\left(\frac{2x}{3y^2}\right)[/tex] multiplied with itself due to the cube exponent on the outside.

So,

[tex]\left(\frac{2x}{3y^2}\right)^3 = \left(\frac{2x}{3y^2}\right)*\left(\frac{2x}{3y^2}\right)*\left(\frac{2x}{3y^2}\right)\\\\\left(\frac{2x}{3y^2}\right)^3 = \frac{2x*2x*2x}{(3y^2)*(3y^2)*(3y^2)}\\\\\left(\frac{2x}{3y^2}\right)^3 = \frac{(2*2*2)*(x*x*x)}{(3*3*3)*(y^2*y^2*y^2)}\\\\\left(\frac{2x}{3y^2}\right)^3 = \frac{8x^3}{9y^6}\\\\[/tex]

-------------------

Or another approach you could take is to cube each component of the fraction. The rule I'm referring to is [tex]\left(\frac{a}{b}\right)^c = \frac{a^c}{b^c}[/tex]

Applying that rule will lead to:

[tex]\left(\frac{2x}{3y^2}\right)^3 = \frac{(2x)^3}{(3y^2)^3}\\\\\left(\frac{2x}{3y^2}\right)^3 = \frac{2^3*x^3}{3^3*(y^2)^3}\\\\\left(\frac{2x}{3y^2}\right)^3 = \frac{8x^3}{27y^{2*3}}\\\\\left(\frac{2x}{3y^2}\right)^3 = \frac{8x^3}{27y^6}\\\\[/tex]

Either way you should get 8x^3 all over 27y^6 as one fraction.

A kid’s bicycle costs $110.00 at a department store, who is offering a 15% off coupon. Determine the final price of the bike after both the discount and 6.25% sales tax.

Answers

Answer:

103.125

Step-by-step explanation:

110.00 times 15% = 16.5

16.5 times 6.25% = 103.125

Answer - 103.125

Answer:

With the coupon and sales tax, the bicycle costs $100.38.

Step-by-step explanation:

First, we need to find 6.25% of $110.

110 x 0.0625 = 6.88

Now, let's add this to the total, or $110.

110 + 6.88 = $116.88

After that, we need to find 15% of this total.

116.88 x 0.15 = 17.53

Now, we need to subtract this from the total, which is now $116.88.

116.88 - 16.5 = $100.38

Now, with the coupon and sales tax, the bicycle costs $100.38.

Hope this helps! :D

What is the missing numerator? blank over five plus eighteen over twenty equals thirty over twenty 8 5 3 2

Answers

Given:

[tex]\dfrac{?}{5}+\dfrac{18}{20}=\dfrac{30}{20}[/tex]

To find:

The missing value.

Solution:

Let x be the missing value.

We have,

[tex]\dfrac{x}{5}+\dfrac{18}{20}=\dfrac{30}{20}[/tex]

[tex]\dfrac{x}{5}+\dfrac{9}{10}=\dfrac{3}{2}[/tex]

Subtract [tex]\dfrac{9}{10}[/tex] from both sides.

[tex]\dfrac{x}{5}=\dfrac{3}{2}-\dfrac{9}{10}[/tex]

[tex]\dfrac{x}{5}=\dfrac{15-9}{10}[/tex]

[tex]\dfrac{x}{5}=\dfrac{6}{10}[/tex]

[tex]\dfrac{x}{5}=\dfrac{3}{5}[/tex]

Multiplying both sides by 5, we get

[tex]x=3[/tex]

So, the missing value is 3.

Therefore, the correct option is C.

Describe the slope of the line. (-3,1) and (2,-2) The slope is _____, find the slope m=?

Answers

Answer:

[tex]m = - \frac{3}{5}[/tex]

Step-by-step explanation:

The slope of the line is -3/5 which line passes through points (-3,1) and (2,-2).

What is the slope of the line?

The slope of the line is defined as the angle of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Consider two points on a line—Point 1 and Point 2.

Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)

Given,

The line passes through the points (-3,1) and (2,-2)

We have,

x₁ = -3, y₁ = 1

x₂ = 2, y₂ = -2

∵ Slope m = (y₂ - y₁)/(x₂ -x₁  )

Substitute the above values in the formula, and we get

The slope of the line = (-2 - 1) / (2 - (-3))

The slope of the line = (-2 - 1) / (2 +3)

The slope of the line = -3/5

Thus, the slope of the line is -3/5 which line passes through points (-3,1) and (2,-2).
