Answer:

The coordinates of the center of the circle is (-1,-0.5)

Step-by-step explanation:

The coordinates of the center are only the midpoint coordinates of the endpoint

Mathematically, that will be;

(x,y) = (x1 + x2)/2, (y1 + y2)/2

= (-4+2)/2, (4-3)/2

= (-2/2),(-1/2)

= (-1, -0.5)

Answer:

Danny did not reverse the symbol.

Hence, the correct answer is: [tex]x<-7[/tex]

Step-by-step explanation:

Given the inequality

[tex]- 8x > 56[/tex]

We know that when we multiply both sides by -1, the 'inequality' gets reverse.

i.e.

[tex]\left(-8x\right)\left(-1\right)<56\left(-1\right)[/tex]

[tex]8x<-56[/tex]

Divide both sides by 8

[tex]\frac{8x}{8}<\frac{-56}{8}[/tex]

[tex]x<-7[/tex]

Therefore, Danny did not reverse the symbol.

Hence, the correct answer is: [tex]x<-7[/tex]

Answer:

-15

Step-by-step explanation:

Answer: w = -15

Step-by-step explanation:

-9 = 6 + w

Solve to isolate W.

-9 = 6 + w

-6    -6  

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

-15 = w

Based on the info provided, that should be right!

*Note that I'm assuming the prism is a triangular prism

Volume = 60cm³

Height = 6cm

Width = 2cm

The equation for the volume of a triangular prism is:

V = [tex]\frac{b * h * l}{2}[/tex]

Let's substitute in the values we already know:

60 = [tex]\frac{2 * 6 * l}{2}[/tex]

And now we need to make l the subject by multiplying both sides by 2:

120 = 2 x 6 x L

Simplify:

120 = 12L

Flip to make easier to read:

12L = 120

Divide both sides by 12 to get the value of L (length):

L = 10

And let's show proof that L = 10 (remember that V (volume) should be equal to 60):

V = [tex]\frac{2 * 6 * 10}{2}[/tex]

V = [tex]\frac{120}{2}[/tex]

V = 60

Therefore we can determine the the length is indeed 10cm.

I hope this helped! :)

Answer: $29850

Step-by-step explanation:

From the question, we are informed that Kevin earned $28,500 in gross wages last year and had $1,350 in capital gains.

The amount of Kevin's income from last year that is subject to income tax will be the addition of the amount he earned and his capital gains. This will be:

= $28500 + $1350

= $29850

5 - 3 = 2

6/2 = 3

Answer:

-5 ≤ n ≤ 3

Step-by-step explanation:

Firstly we solve the equation two at a time;

5n + 17 ≥ n - 3

5n - n ≥ -3 - 17

4n ≥ -20

n ≥ -5

-5 ≤ n

n - 3 ≥ -15 + 5n

n - 5n ≥ -15 + 3

-4n ≥ -12

-n ≥ -3

n ≤ 3

Therefore,

5n+17 ≥ n–3 ≥ –15+5n, becomes

-5 ≤ n ≤ 3

Answer:

Step-by-step explanation:

From ΔABD:

                   BD² + 7² = x²   ⇒  BD² = x² - 49

Form ΔBCD:

                   BD² + 3² = BC²   ⇒  BD² = BC² - 9

so:

       BC² - 9 = x² - 49   ⇒  BC² = x² - 40

From ΔABC:

                 x² + BC² = (7+3)²

                  x² + x² - 40 = 10²

                   2x² = 140

                    x² = 70

                    x = √70                    

Answer:

x = [tex]\sqrt{70}[/tex]

Step-by-step explanation:

Δ ABC and Δ ADB are similar, thus ratios of corresponding sides are equal, that is

[tex]\frac{AB}{AD}[/tex] = [tex]\frac{AC}{AB}[/tex] ( cross- multiply )

AB² = AC × AD = 10 × 7 = 70 ( take the square root of both sides )

AB = x = [tex]\sqrt{70}[/tex]

Step-by-step explanation:

increment in x: from 0 to 3 = 3

increment in y: from -1 to 5 = 6

slope = increment in y / increment in x = 2

it's positive because for increasing x, y is also increasing
