Step-by-step explanation:

4x -24=-y

-24-4x=y

then do calculation

Answer:

infinite solutions

Step-by-step explanation:

substitute y in the first equation

4x+(-4x+24)=24

4x and -4x cancel out

24/24=1

or solve for x, you should also get 1

therefore, infinite solutions. you can also try using a graphing calculator

The answer will be 1/10. First you will change the denominator to the same number because you can’t mutiply fractions if the denominator is different. 5x2=10 and 2x5=10. So both of the denominator will turn into a 10. Now you’ll have to find the numerator. For the first one, multiply it by 2 because that how much the number need to turn equalvilant for the denominator. 1x2=2. So now you know that the first fraction is 2/10. Then you multiply 1 with 5 which is 5. Now the numbers all have the same denominator. Multiply 2/10 and 5/10 which is 1/10.

Answer:

for ac I got 11

ab i got 14

I'm not quite sure tho

but you could use SOH CAH TOA to find ab then use Pythagoras theorem to find AB

Answer:

AB = 11.6 inches

AC = 7.3 inches

m∠B = 39°

Step-by-step explanation:

To calculate side AB (c) put b (9 inches) over the sine of β (51°).

c = 9/sin(51)

The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle, to the length of the longest side of the triangle (the hypotenuse). This would be about 0.777.

c = 9/0.777

I recommend using a fraction here. 0.777 becomes 777/1000. Find the reciprocal (1000/777). Switch the sign to multiplication.

c = 9/1 * 1000/777

Cross cancel if needed.

c = 3/1 * 1000/259

Now multiply.

c = 3000/259

Divide 3000 by 259.

c ≈ 11.5830116 inches ≈ 11.6 inches

Now we know AB. To find AC, find the square root of AB² - BC².

AC = √(11.6² - 9²)

Square both 11.6 and 9.

AC = √(134.56 - 81)

Add 134.56 and 81 to get 53.56

AC = √53.56

Find the square root of 53.56

AC ≈ 7.31846979 ≈ 7.3 inches.

Finding the measure of angle B is comparatively simple. Subtract 51 from 90 to get 39° for angle B.

Step-by-step explanation:

13x-4 = 8x+11

13x-4 = 8x+11

-8x       -8x

5x-4=11

The value of AD is: AD = 35.

Here, we have,

from the given figure, we get,

both the triangles are similar to each other.

so, we have,

AD = DC

i.e.

13x-4 = 8x+11

To solve the equation 13x - 4 = 8x + 11, we need to isolate the variable x on one side of the equation.

Here are the steps:

Start by moving the terms with x to one side of the equation.

We can do this by subtracting 8x from both sides:

13x - 8x - 4 = 8x - 8x + 11

Simplifying the left side:

5x - 4 = 11

Next, move the constant term (-4) to the other side by adding 4 to both sides of the equation:

5x - 4 + 4 = 11 + 4

Simplifying:

5x = 15

To isolate x, divide both sides of the equation by the coefficient of x, which is 5:

(5x)/5 = 15/5

Simplifying:

x = 3

Therefore, the solution to the equation 13x - 4 = 8x + 11 is x = 3.

so, we get, x = 3

Plug it in AD, we have,

13(3) -4

=39-4

=35

Hence, The value of AD is: AD = 35.

Answer:

Step-by-step explanation:

Amount of calories per hour whkie riding = 236

Amount of calories she intends to burn = 590

The number of hours she must ride her bike :

Let number of hours = x

Hence,

(Calories burned per hour * number of hours) ≥ 590

(236 * x) ≥ 590

x ≥ 590 / 236

x ≥ 2.5

Hence she must rise her bike for 2.5 hours

Given:

g(x) vertical shift of [tex]f(x)=-x[/tex] up 3 units followed by a vertical stretch by a factor of 4.

To find:

The rule for g(x).

Solution:

We have,

[tex]f(x)=-x[/tex]

This function shifts 3 units up. So,

[tex]f(x)+3=-x+3[/tex]

This function vertical stretch by a factor of 4. So,

[tex]g(x)=4(f(x)+3)[/tex]

[tex]g(x)=4(-x+3)[/tex]

[tex]g(x)=-4x+12[/tex]

Therefore, the rule for g(x) is [tex]g(x)=-4x+12[/tex].

Answer:

Therefore, the side lengths 10, 14, and 15 form a triangle.

Step-by-step explanation:

The Triangle Inequality Theorem defines that if we are given the three sides of a triangle, then the sum of any 2 sides of a triangle must be greater than the measure of the third side of the triangle.

The three conditions that need to be met for any triangle with the side lengths A, B, and C.

[tex]A + B > C[/tex]

[tex]B + C > A[/tex]

[tex]A + C > B[/tex]

Given the side lengths of a triangle

Let us check whether it satisfies the three conditions.

10+15 > 14     →  TRUE

10+14 > 15     →  TRUE

14+15 > 10    →  TRUE

As all the conditions are met. Therefore, the side lengths 10, 14, and 15 form a triangle.

Answer:

The missing angle I believe is 25%.

Step-by-step explanation:

180-130=50

Divide 50 by 2 and it equals 25. 25 degrees for each angles.

Answer:25

Step-by-step explanation:

alright so the triangle theorem states that all of the angles of a triangle add up to 180. we already of 130 so we take away 130 from 180 to get 50. If you see the two little lines on the triangles sides opposite of the two angles that we are missing then you can tell by those lines that the angles opposite of them are equal to each other. So you divide 2 from 50 to get 25 which is the value of x. Hope you understand this (:

Answer:

Kindly check explanation

Step-by-step explanation:

Give the line of best fit :

y = 1.62x + 18 ; where ;

y = wait time ; x = number of staffs available

If slope of the line is -1.62.

The slope of linear graph represents the ratio of change in the y variable and the x variable. With a slope value of - 1.62, the rate of change is negative and thus an increase in x will lead to a decrease in y. This means that for every unit increase in the number of staffs, the wait time reduces at a rate of 1.62 per unit.

Each of these courses will take up 1/8 of the total semester.

Step-by-step explanation:

From the question, we can see that the semester is remaining 3/4 of the total duration.

we will be sharing that 3/4 into 6 places for each course. Next, we will be relating this to the total time we had for the whole semester initially.

3/4 divided by 6 = 1/8

From this, we can see that each of these  courses will take up 1/8 of the total semester.
