I suggest graphing this on desmos! That site will be your best friend when it comes to graphing, anyway I hope this helped!

8(u-4)=-40

8u-32= -40

8u= -40 + 32

8u= -8

u= -8/8

u= -1

Let's check

8(-1 -4)

-8-32

=-40

So yes u is -1

Answer:

C. Sin 75,5 = y/12

Step-by-step explanation:

This angle can be calculated using the law of sine:

sin(angle)=opposite cathete/hypothenuse

sin(angle)=wall/ladder

In this exercise we want to calculate the height of the ladder, so the equation is changed afterwards.

sin(angle)=wall/ladder

sin(75,5°)=12ft/y

The height y above the ground in feet is ; (C ) sin 75.5 = y / 12

The ladder, the horizontal ground and the vertical height above the ground form a right angle triangle are ;

The vertical height y = opposite

Length of ladder = hypotenuse

Horizontal ground  = adjacent.

According to trigonometry, sine of an angle is opposite/hypotenuse

sin 75.5 = y/12.

In conclusion, the height y above the ground in feet is sin 75.5 = y / 12.

Answer:

He can fit 2 more DVD's on the shelf.

And he'll have about 12 mm of extra space left.

Step-by-step explanation:

40×1.4 = 56cm  This is the length of space the 40 DVD's will take up.

60-56 = 4cm  This is the amount of space left.

4/1.4 = 2.857   the number of DVD's that will fit.

Of course, the decimal represents a partial DVD which is worthless.

Just to be sure, 2×1.4 = 2.8cm OK. But  3×1.4=  4.2cm which is 2mm too much

Answer:

B 50=n(125) 40%

Step-by-step explanation:

The percent equation, 125 = n(50); 250%

A number or ratio which can be expressed as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The percentage therefore refers to a part per hundred. Per 100 is what the word percent means. The letter "%" stands for it. There is no dimension to percentages. As a result, it is known as a dimensionless number. When we say a number is 50% of something, we mean that it is 50% of everything.

As in 0.6%, 0.25%, etc., percentages can also be expressed as decimals or fractions. The grades earned in any subject have been calculated in terms of percentages in academics.

Let the required percentage be x%.

A/c to question,

[tex]\frac{x}{100} * 50= 125\\\\ x=250[/tex]

That is, required percentage is 250%.

Hence, option C is correct.

Answer: 60%

Step-by-step explanation:

Given: Climbing rate at the end of week 1 = 25 steps per minute.

Climbing rate at the end of week 4 =   60 steps per minute

The  percent increase in Maggie's rate of climbing steps from the end of week 1 to the end of week 4 will be :

[tex]\dfrac{\text{Climbing rate after week 4 - Climbing rate after of week 1}}{\text{Climbing rate after week 1}}\times100[/tex]

[tex]=\dfrac{40-25}{25}\times100\\\\=\dfrac{15}{25}\times100=15\times4=60\%[/tex]

Hence, the percent increase in Maggie's rate of climbing steps from the end of week 1 to the end of week 4 = 60%

Answer: $37.20

Step-by-step explanation:

24.50+12.70=37.20

Quinn earned a total amount of $37.20 which is the addition of the earnings from dog-sitting and the recycling cans.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

We have been given that Quinn earned $24.50 for dog-sitting and $12.70 for recycling cans.

We have to determine the total amount he earned.

The total amount is the addition of the earnings from dog-sitting and the recycling cans.

The total amount = earnings from dog-sitting + earnings from the recycling cans.

The total amount = $24.50 + $12.70

The total amount = $37.20

Therefore, he earned a total amount of $37.20.

Answer:

To get 2 imaginary solutions, c must be less than -2

Step-by-step explanation:

The general form of the quadratic equation is:

[tex]ax^2+bx+c=0[/tex]

Solve the quadratic equation by using the formula:

[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

The equation to solve is:

[tex]-2x^2+4x+c=0[/tex]

In our equation: a=-2, b=4, c=unknown

For the roots to be imaginary, the argument of the square root must be negative, that is:

[tex]b^2-4ac<0[/tex]

Substituting the known values:

[tex]4^2-4(-2)c<0[/tex]

[tex]16+8c<0[/tex]

Subtracting 16:

[tex]8c<-16[/tex]

Solving:

[tex]c<-2[/tex]

Thus, to get 2 imaginary solutions, c must be less than -2

Answer:

$63.55

Step-by-step explanation:

Taxes are charges paid by individuals and enforced by the government in other to fund government spending and various public expenditures.

The flowers cost $59.95 and tax is 6%.

Tax = 6% of flower cost = 0.06 × $59.95 = $3.6

The  total cost of the flowers is the sum of tax and the cost of flowers, hence:

Total cost of the flowers = $59.95 + $3.6

Total cost of the flowers = $63.55

8) -3

9) -5/11

10) 2/5

11) -0.5

12) -2

Answer:

The answer is below

Step-by-step explanation:

Let x represent the cost of apples, y represent the cost of strawberries and z represent the cost of oranges.

The money used to buy 2 apples, 3 boxes of strawberry, and 4 oranges is represented as:

2x + 3y + 4z = 15.3         (1)

The money used to buy 4 apples, 1 boxes of strawberry, and 2 oranges is represented as:

4x + y + 2z = 10.9       (2)

The money used to buy 5 apples, 2 boxes of strawberry, and 1 oranges is represented as:

5x + 2y + z = 13.7        (3)

Solving equation 1, 2 and 3 simultaneously gives:

x = $1.5, y = $2.5 and y = $1.2

The cost of orange is $1.5, cost of strawberry = $2.5 and cost of orange = $1.2

Answer:

D. b = r+z

Step-by-step explanation:

Given the expression b-r = z, we are to solve for b. To do this, we will add 'r' to both sides of the equation as shown;

b-r+r = z+r

Since -r+r = 0, substitute:

b+0 = z+r

b = z+r

Hence the resulting equation when r is added to both sides of the equation is b = z+r

Hence option D is correct
