4x - 8 = -4

4x = -4+8

4x = 4

x = 4/4

x = 1

To check the answer, we replace x with 1 in the original equation. After simplifying, we should get the same thing on both sides

4x - 8 = -4

4(1) - 8 = -4

4 - 8 = -4

-4 = -4

The answer is confirmed.

true? I believe due to how it starts with positive 4 and is subtracted by -8 this conceding a negative number.

top hole

x = 38 cos 60

y = 38 sin 60

bottom hole

x = 38 cos 30

y = 38 sin 30

The coordinate of holes is (43.3, 25) and (25, 43.3).

It is a special kind of ellipse whose eccentricity is zero and foci are coincident with each other. It is a locus of a point drawn at an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

Given

A steel plate has the form of one-fourth of a circle with a radius of 54 centimeters.

Two 2 centimeter holes are drilled in the plate.

Two 2 centimeter holes are drilled in the plate, positioned.

Holes are at 50 cm from the center at an angle of 30 and 60 degrees.

So the coordinate will be given by

[tex]\rm x = r\ cos \theta \ \ \ \ \ \ \ \ y = r\ sin \theta[/tex]

Then for the first hole r = 50, at 30 degrees,

[tex]\begin{aligned} & \rm x = r\ cos \theta \ \ \ \ \ \ \ \ & \rm y = r\ sin \theta\\& \rm x = 50 *cos30 \ \ \ \ \ \ \ \ & \rm y = 50 sin30\\& \rm x = 43.3 \ \ \ \ \ \ \ \ & \rm y = 25\\\end{aligned}[/tex]

For the second hole r = 50, at 30 degrees,

[tex]\begin{aligned} & \rm x = r\ cos \theta \ \ \ \ \ \ \ \ & \rm y = r\ sin \theta\\& \rm x = 50 *cos60 \ \ \ \ \ \ \ \ & \rm y = 50 sin60\\& \rm x = 25 \ \ \ \ \ \ \ \ & \rm y = 43.3\\\end{aligned}[/tex]

Thus the coordinate of holes is (43.3, 25) and (25, 43.3).

Answer:

- 7x^2 + 3xy - 9y

Step-by-step explanation:

(2xy- 4x^2) - (9y + 3x^2 - xy)

Add the second polynomial:

Change all the signs in the second polynomial because it has a negative sign before the parentheses.

= 2xy - 4x^2 - 9y - 3x^2 + xy

Combine like terms:

(-4x^2 - 3x^2) + (2xy + xy) - 9y

= -7x^2 + 3xy - 9y

Answer:

m∠1 = 75° m∠2 =45° m∠3 = 60°

Step-by-step explanation:

m∠1 = 180 - { (180 - 135) + (180 - 120) }

m∠1 = 180 - { 45 + 60 }

m∠1 = 75°

The angle between 1 and 3, lets call it x,  is vertically opposite to ∠2, so we must find it first to be able to get ∠2

Since a ║b

Therefore ∠x and ∠135 are co-interior angles

Therefore ∠x = 180-135

m∠x = 180 - 135

m∠x = 45°

∠2 = ∠x (Vertically opposite angles)

∠2 = 45°

Between ∠2 and ∠3 there is an angle, let's call it z.

∠z = ∠1 (Vertically opposite angles)

∠z = 75°

Since the sum of angles 2, z and 3 = 180° (Straight angle)

Therefore m∠3 = 180 - (∠2 + ∠z)

m∠3 = 180 - (45 + 75)

m∠3 = 60°

Or in a different way

∠2 + ∠z + ∠3 = 180

45 + 75 + ∠3 = 180

120 + ∠3 = 180

∠3 = 180 - 120

∠3 = 60°

Answer:

It's the last option "24 + 49i + 15i^2"

Step-by-step explanation:

To solve you must do FOIL, (First, Outer, Inner, Last). To do this, you must do:

8 × 3 = 24 , 8 × 5i = 40i , 3i × 3 = 9i , and

3i × 5i = 15i^2 .

Don't forget to combine like terms.

Altogether: 24 + 49i + 15i^2 .

Answer: 9+49i

Step-by-step explanation:

Answer:

the answer is the 3rd one.

Step-by-step explanation:

Using distance between two points, it is found that Jose traveled 25 units of length to football practice.

The distance between two points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is given by:

[tex]D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

First, Jose goes from his house, at (-6,8), to Tyrell's house, at (6,8), thus:

[tex]D_1 = \sqrt{(6 - (-6))^2 + (8 - 8)^2} = \sqrt{12^2} = 12[/tex]

Then, he goes from Tyrell's house, at (6,8), to the football field, at (6, -5), thus:

[tex]D_2 = \sqrt{(6 - 6)^2 + (-5 - 8)^2} = \sqrt{13^2} = 13[/tex]

The total distance is:

[tex]D = D_1 + D_2 = 12 + 13 = 25[/tex]

Jose traveled 25 units of length to football practice.

Part A

Answers:

x+y = 125

x = y+45

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

Explanation:

The first equation represents Angela playing both sports a combined 125 minutes. We simply add the variables x and y to represent adding the times for soccer (x) and golf (y).

Because she plays soccer 45 minutes more compared to golf, we also have the equation x = y+45.

==========================================================

Part B

Answer:  40 minutes

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

Explanation:

The second equation from part A says x = y+45

Because of this, we'll replace the 'x' in the first equation with y+45 and solve for y. I'm using the substitution rule.

So,

x+y = 125

y+45+y = 125 .... replace x with y+45

2y+45 = 125

2y = 125-45

2y = 80

y = 80/2

y = 40 minutes is the amount of time playing golf per day.

==========================================================

Part C

Answer: No it's not possible.

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

Explanation:

We found that y = 40 earlier. Let's used this to find x

x = y+45

x = 40+45

x = 85

Therefore, Angela spends 85 minutes playing soccer everyday. It's close to 80 minutes, but not quite there. So it's not possible that she spent 80 minutes playing soccer everyday.

Another way to show this is to say x+y = 80+40 = 120 which is five minutes short of the 125 minute goal.

Answer:

1: C) Yes, because the last digit is 6, which is divisible by 2

2: B) Yes, because the sum of 2+1+6=9, which is divisible by 3

3: C) Yes, because the last digit of the number is 0

Step-by-step explanation:

Let's start with the first one. Is 26 divisible by 2? Yes, it is, because the last digit is 6, which is divisible by 2. To check to make sure we are right, we simply divide 26 by 2. Can it be done? Yes, 26 divided by 2 is 13, so we are right.

What about number two? Is 216 divisible by 3? Well, the rules divisiblity rules change for 3. For three, the sum of the digits of the number must be divisible by three. Do 2, 1, and 6, when added together, equal a number that is divisible by 3? Well, 2+1+6 is 9, and 9 is divisible by three, so the answer is B.

For the last one we need to check the divisibility rule for ten. The rule is that if the number ends in 0, it is divisible by 10. Does 40,100 end in a zero? Yes, so the answer is C.
