I need help solving question number 9!

Answer:

2 and 3

Step-by-step explanation:

2 twice is 4 and 4 is one more than 3. 3 plus 2 is 5.

The two numbers are 2 and 3.

A number is a basic unit of mathematics. Numbers are used for counting, measuring, and comparing amounts. A number system is a set of symbols, or numerals, that are used to represent numbers.

Given that, Twice, one number is equal to one more than a second number. The sum of the numbers is five.

Let the numbers be a and b, establishing the equations,

2a = b+1

2a-b = 1........(i)

a+b = 5..........(ii)

Adding the equations, we get,

a = 2

b = 3

Hence, the two numbers are 2 and 3.

Step-by-step explanation:

Answer:

See answer below

Step-by-step explanation:

Given the expressions

8 × 1/9, 4 × 4/5, 6 × 1/5, 9 × 1/2, 1 × 2/5, 9 × 1/9

We are to check which is less than 1, equal to 1 and greater than 1

For 8×1/9

8×1/9 = 8/9

8/9 = 0.889<1

Hence 8/9 is less than 1

For 4 × 4/5

4 × 4/5 = 16/5

16/5 = 3 1/5

3 1/5 =3.2>1

Hence 4 4/5 is greater than 1

For 6×1/5;

6×1/5 = 6/5

6/5 = 1.2 >1

Hence 6×1/5 is greater than 1

For 9 × 1/2:

9 × 1/2 = 9/2

9/2 = 4.5>1

Hence 9× 1/2 is greater than 1

For 1×2/5;

1×2/5 = 2/5

2/5 = 0.4<1

Hence 1×2/5 is less than 1

For 9×1/9

9×1/9 = 9/9

9/9 = 1

Hence 9×1/9 is equal to 1

Answer:

x=29

Step-by-step explanation:

because the two sides of the acute triangle are the same length, the ones at the bottom are the same as well. the total of the angles of a triangle is 180, and we know that one of the angles are 64 so we subtract that from 180 and get 116 which we divide by two to get the other two angles: 58 and 58. at the bottom of the image, two angles are connected and make a straight 180 line so we can take 58 out of that 180 and get 122 in the obtuse angle and divide by two to get 29 in the acute angles of the obtuse triangle.

Answer:

5h>15

Step-by-step explanation:

✓From the question, we were informed that Lucy walks at a rate of 5 miles per hour, this implies that 5 is multiplied by amount of hours (5×1h)= 5h

✓ we need to find the inequality that Lucy can use to find H the number of hours she should walk in order to meet or exceed her goal, To find this as equation, we know that Lucy must walk for at least 15 miles which implies that the (5h) will always be greater than 15 miles. We can put it in equation as

5h>15

Answer:

25 miles

Step-by-step explanation:

Step one:

given data

We are told that   20 gallons of gas can go 410 miles

what we want is the number of miles that 50 gallons can go

Step two:

so

20 gallons will go 410 miles

50 gallons will go x

cross multiply

20x=50*40

divide both sides by 20

x= 500/20

x=25 miles

Answer:

The equation, y=3x-5 is in y=mx+b format. The b, or -5 in this case, tells you what the y intercept is, or in this case, your starting point. This means your first point will be at (0,-5). The mx, or 3x in this case, tell us how much to move     up and how much to move sideways. 3x is equal to 3/1x and the 3/1 tells us the rise/run. Rise being how much to go up or down and run being how much to go to the left or right. So in 3x, the rise is 3 and the run is 1. So you will go 3 up on the y axis and 1 to the right on the x-axis. So your next point will be (1, -2) and the point after that will be (2, 1) and so on!

hope this helped!

Answer:

Step-by-step explanation:

y=3x-5 is a line

pick any 2 points for example

(x=0, y=(3*0)-5=-5) so one point is (0,-5)

(x=2, y=(3*2)-5= 1) so another point is (2, 1)

draw a line trough points (0, -5) and (2, 1)

A. Solution to [tex]y \ge x^2 - 4[/tex] but not to [tex]y < 2x - 1[/tex]

Step-by-step explanation:

Given

[tex]y \ge x^2 - 4[/tex]

[tex]y < 2x - 1[/tex]

Required

Is [tex](0,0)[/tex] a solution?

[tex](0,0)[/tex] implies that:

[tex]x = 0\ and\ y = 0[/tex]

To check if it is a solution or not, we simply substitute 0 for x and for y in the given inequalities

[tex]y \ge x^2 - 4[/tex] becomes

[tex]0 \ge 0^2 - 4[/tex]

[tex]0 \ge 0- 4[/tex]

[tex]0 \ge - 4[/tex]

This solution is true

[tex]y < 2x - 1[/tex] becomes

[tex]0 < 2 * 0 - 1[/tex]

[tex]0 < 0 - 1[/tex]

[tex]0 < - 1[/tex]

This solution is not true because 0 is greater than 1.

The value of B is 16.

The correct option is B

A basic quadratic equation, or a second-order polynomial equation with a single variable, is represented by the equation x : ax² + bx + c = 0, where a≠0 for the variable x. As it is a second-order polynomial equation, which is ensured by the algebraic fundamental theorem, it must have at least one solution.

The standard equation for a hyperbola centered at the origin is:

(x²)/(a²) - (y²)/(b²) = 1

where "a" and "b" are the lengths of the transverse and conjugate axes, respectively. To find the value of "b" for the given hyperbola equation, we need to first rewrite it in the standard form.

(x²)/(24²) - (y²)/(b²) = 1

Multiplying both sides by (24²)(b²), we get:

b²(x²) - (24²)(y²) = (24²)(b²)

Dividing both sides by (24²), we get:

b²(x²)/(24²) - y² = b²

Comparing this with the standard equation, we can see that a = 24 and b is the square root of the constant term, which is b² = 576. Therefore, b = 24.

However, the given directrix of x = 576/26 is not consistent with the equation of the hyperbola. The directrix for a hyperbola with center at the origin and transverse axis along the x-axis is given by x = a²/b. Using the value of a = 24, we can find the directrix as:

x = (24²)/b

Setting this equal to 576/26, we get:

(24²)/b = 576/26

Solving for b, we get:

b = 16

Therefore, the correct answer is (B) 16.

Integrate both sides with respect to t :

∫ dy/dt dt = ∫ -12t ² dt

y(t) = -4t ³ + C

Use the initial condition to solve for C :

5 = -4•0³+ C

C = 5

So

y(t) = -4t ³ + 5

and the answer is D.

Alternatively, you can directly apply the fundamental theorem of calculus:

[tex]\dfrac{\mathrm dy}{\mathrm dt}=-12t^2\implies y(t)=y(0)+\displaystyle\int_0^t -12u^2\,\mathrm du[/tex]

[tex]\implies y(t)=5-4u^3\bigg|_0^t[/tex]

[tex]\implies y(t)=5-4t^3[/tex]

Answer:

x=27

Step-by-step explanation:

since lime m is parralell to line n, that means adjacent angles are equal to each other x and 27 are adjacent because they are across from each other basically. therefore, x is equal to 27 degrees.
