Answer:

X = 3

Step-by-step explanation:

-(-5) is also the same as + 5, so the equation would be 8x + 5 = 29

Subtract 5 from both side of the equation

8x+5-5 = 29 -5

8x = 24

Then divide both sides by 8

Final answer x=3

the answer is A

Step-by-step explanation:

The answers is: 33

33 is the integer that represents her location relative to the surface after 7 seconds.

And 33 feet far the diver have to go to return to the surface.

Step-by-step explanation:

Given:

A scuba diver is 15.5 feet below the surface of the water.

The diver continues to swim downward at a rate of 2.5 feet per second.

Now, to find the integer represents her location relative to the surface after 7 seconds.

And to find how far does the diver have to go to return to the surface.

So, to get the integer represents her location relative to the surface after 7 seconds.

Initial depth = 15.5 feet.

Distance traveled down = 7 × 2.5 = 17.5 feet.

Final depth of water surface = Initial depth + Distance traveled down.

Final depth of water surface = 15.5 feet + 17.5 feet.

Final depth of water surface = 33 feet.

Thus, 33 is the integer represents her location relative to the surface after 7 seconds.

Now, to get how far does the diver have to go to return to the surface:

As, the diver goes to 33 feet down to the surface.

Thus, the diver to return she have to go through the same distance.

So, to return to the surface she need to go to 33 feet far.

Therefore, 33 is the integer that represents her location relative to the surface after 7 seconds.

And 33 feet far the diver have to go to return to the surface.

Answer:

C.  we try y + 4 = 98 + 1 = 98/98 + 4 = 102/ 98  = 1.04 so inverse is 8 / 9

Step-by-step explanation:

y2-y1 / x2-x1

7--1 / 5--4

7+1 / 5+4

8 / 9

m = 8/9

y+1 = ? (x+ 4)

we know y^1 will be added or subtracted at end to show the +1 so added.

so we try 87x + 348 + 1 = 87x + 349 = 87/349 = 1/4 so no

we try 89x + 349 = 89/349 = 0.255 so no

we try y + 4 = 98 + 1 = 98/98 + 4 = 102/ 98  = 1.04 so inverse is 8 / 9

we try y+1 = 89x + 356 + 4 = 360/89 = 1/4 = 0.247222222 so no

we test

89/.360 = 1/4 so no

we test 102/ 98 = 0.960784314 = 1 - 0.4

therefore  1 / 1.4 =  0.714285714 which is 7/10 - 10-1.4 = 8.6

and as 7/10 is actually higher 7.14 and 8.6 when we add each side 0.4 we get 8/9

Answer:

37.5

Step-by-step explanation:

cosФ = \(\frac{A}{H}\)

cos(33°35') = \(\frac{m}{45}\)

m = 45 × cos(33°35')

m = 37.5 (1d.p.)

Answer:a

Step-by-step explanation:

The solution to the equation ax² + bx + c = 0 , has a graph that crosses the y-axis once and does not intersect the x-axis, then the equation has one real root and two complex conjugate roots that lie on either side of the axis of symmetry.

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

If the graph of the equation ax² + bx + c = 0 crosses the y-axis once, it means that the equation has one real root. This is because when x = 0, the equation becomes:

c = 0² + 0 + c = c

Therefore, the point (0, c) is on the y-axis, which means the graph crosses the y-axis once.

If the graph does not intersect the x-axis, it means that the discriminant b² - 4ac is negative. This is because the discriminant determines the nature of the roots of a quadratic equation, and when it is negative, the roots are complex (not real) and the graph does not intersect the x-axis.

So, the solution(s) of the equation ax² + bx + c = 0 are:

x = (-b ± √(b² - 4ac)) / 2a

Since the discriminant is negative, the term inside the square root is negative, and there are no real solutions for x. Instead, the solutions are complex conjugates of the form:

x = (-b ± i√(4ac - b²)) / 2a

where i is the imaginary unit. Since the real part of these solutions is -b/2a, which is the axis of symmetry of the parabola, and the parabola does not intersect the x-axis, the complex roots will be a conjugate pair that lie on either side of the axis of symmetry.

Hence , the quadratic equation is solved

Answer:

B

Step-by-step explanation: The box represents the middle 50% of the data, with the bottom and top of the box representing the first and third quartiles, respectively. The line inside the box represents the median.

The whiskers extend from the box to show the range of the data, excluding outliers. Outliers are typically shown as individual points outside the whiskers.

Based on this information, we can see that the box in the box plot represents the middle 50% of the data. Therefore, the answer is B. The box, from 44 to 52, includes about 50% of the data.

Answer:

Yes

Step-by-step explanation:

First ration we will divide by 5 (both numbers) and second one by 3 (again both numbers).

First ratio becomes         (25:5)/(45:5) = 5/9

Second ratio becomes    (15:3)/(27:3) = 5/9

Since we can simplify them in that way that both are the same that means they are proportional.

because when we make them smaller like 25/45 divide by 5 and 15/27 divide by 3 it forms 5/9

Answer:

Yes

Step-by-step explanation:

If you divide 25/45 by 5 you get 5/9

Then you divide 15/27 by 3 you also get 5/9

Since both are equal to 5/9 they are proportional.

Answer:

it would be k=50 (pounds) because it goes up 50 each point

Answer:

Step-by-step explanation:

basically here we wanna get y by itself

so

2x + 3y = -1

subtract 2x from both sides

3y = -2x -1

then to get y by itself we have to divide everything by 3

y = -2/3x - 1/3

this is your equation in slope intercept form

2x = 18

2x / 2 = 18 / 2

x = 9

if we try to solve for x in each equation we can see that 2x - 3 = 15 which is the equation that x is equal to 9

Step-by-step explanation:

I think a scholarship means an opportunity for people to earn an education. Without assistance from an outside source, students may have trouble paying for the degree. Scholarships help students have more time to focus on their studies. For many students, the stresses of working make it difficult for them to graduate on time, or graduate with the high grades they have the potential to achieve. For other students, the work/study life is unsustainable, and they discontinue their studies altogether. And I think scholarships can fill the gap. I feel with the assistance it can support students who fall in the gap between high and low-income levels.
