Answer:

Inconsistent System

Step-by-step explanation:

Answer:

Given equation:  y = x² + 2x - 3

If you wish to find the values of y when x = -2 and x = -5:

When x = -2:

⇒ y = (-2)² + 2(-2) - 3

⇒ y = 4 - 4 - 3

⇒ y = -3

When x = -5:

⇒ y = (-5)² + 2(-5) - 3

⇒ y = 25 - 10 - 3

⇒ y = 12

If you wish to find the value of y when x = -2-5:

When x = -2-5 ⇒ x = -7

⇒ y = (-7)² + 2(-7) - 3

⇒ y = 49 - 14 - 3

⇒ y = 32

Answer:

y = 32

Step-by-step explanation:

Given :-

y = x² + 2x - 3

x = -2-5 = -7

To Find :-

y

Inputting the value of x :

y = (-7)² + 2(-7) - 3

y = 49 - 17

Solution :-

y = 32

Answer:

p = 7

Step-by-step explanation:

6p - 10 and 32 are vertically opposite angles and are congruent , then

6p - 10 = 32 ( add 10 to both sides )

6p = 42 ( divide both sides by 6 )

p = 7

The expression that is equivalent to the expression [(6c² + 3c)/(-4c + 2)] ÷ [(2c + 1)/(4c - 2)] is; -3c

Simplification of fractions is the process of reducing fractions that involves making the fraction as simple as feasible.

We achieve this by dividing the numerator and denominator by the greatest integer that divides perfectly into both numbers.

The given expression is;

[tex]\frac{[(6c^2 + 3c)(-4c + 2)] }{[(2c + 1)/(4c - 2)]}[/tex]

On Simplifying the fraction equation by factorization we obtained ;

[tex]\frac{[3c(2c + 1)/(-2(2c - 1))]}{[(2c + 1)/(2(2c - 1)]}[/tex]

[tex]\frac{[3c(2c + 1) }{(-2(2c - 1))] \times [(2(2c - 1)/(2c + 1)]}[/tex]

[tex]-3c[/tex]

Hence he expression that is equivalent to the expression [(6c² + 3c)/(-4c + 2)] ÷ [(2c + 1)/(4c - 2)] is; -3c

Answer:

Area of Mrs. Margarita's garden = 1188.39 m²

Step-by-step explanation:

Using the most basic formula to solve this question i.e. Area of circle. We know that: Area of of circle = πr². But in problem we are provided with a half shaped circle. Means we need to use the half of the area of circle or you can say semi-circle.

Now, read the question again. Mrs. Margarita has a garden shaped like a half-shaped circle with a diameter of 55 m. Given diameter is 55 m and we know that radius is half of the diameter. So, radius is 55/2 m. Rest what we need to do is substitute the values and do the rest calculations.

Let's dive in!

= 1/2 × 22/7 × 55/2 × 55/2

= 11/7 × 55/2 × 55/2

= 33275/28

The water level in the river is an illustration of a linear function

The linear function that models the data in the table is [tex]w = 0.8t + 17.9[/tex]

From the complete question, we have the following table:

t      w

1     18.7

1.5  19.1

Start by calculating the slope (m)

[tex]m = \frac{w_2 - w_1}{t_2 -t_1}[/tex]

This gives

[tex]m = \frac{19.1 - 18.7}{1.5 - 1}[/tex]

Evaluate

[tex]m = 0.8[/tex]

The equation is then calculated as:

[tex]w = m(t - t_1) + w_1[/tex]

So, we have:

[tex]w = 0.8(t - 1) +18.7[/tex]

Expand

[tex]w = 0.8t - 0.8 +18.7[/tex]

[tex]w = 0.8t + 17.9[/tex]

Hence, the linear function that models the data in the table is [tex]w = 0.8t + 17.9[/tex]

Answer:

$133.20

Step-by-step explanation:

Since the amount of hours she worked isn't a whole number, we can first separate 18 and 1/2 and work the problem out one at a time.

1. Multiply 7.20 by 18 to get 129.60

2. Multiply 0.50 by 7.20 to get 3.60.

3. Add 129.60 and 3.60 together to get the answer, 133.20.

117 x 3 = p = 351 (entire novel)

Answer:

As the lines are parallel, it shows that the two lines form 180° because they are angles on the same side of the transversal. A transversal is a line that bisects two lines.

Here,

(20x + 5)° + (24x - 1)° = 180°

=> (20x + 24x)° + (5 + (-1)  )° = 180°

=> 44x° + 4° = 180°

=> 44x = (180 - 4)°

=> x = 176 / 44

=> x = 4

Therefore, x = 4 is the solution of the equation.

Answer:

x is equal to 5

Step-by-step explanation:

78 = 12x + 18

12x + 18 = 78

12x = 78 - 18

12x = 60

x = 60/12

x = 5

btw i made 78 equal to 12x + 18 because it is parallel. they both equal the same (i think its called parallel. idrk)

X is equal to 5

78=12x+18

12x=78-18

12x=60

X=60/12

answer : f(t) = 4000 + 170t

f(t) = principal + (principal multiplied by interest rate) multiplied by time

f(t) = 4000 + (4000*.0425)t

f(t) = 4000 + 170t

t = number of years

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

Explanation:

We use the simple interest formula which is

i = P*r*t

where in this case,

We then get the following

i = P*r*t

i = 4000*0.0425*t

i = 170t

Showing that the amount of simple interest earned is 170 times that of the number of years.

For instance, if Carmen waits t = 10 years, then she earns i = 170*t = 170*10 = 1700 dollars in interest alone.

The expression 170t is the interest only. Add on the original amount deposited to find the total account balance after t years. Therefore, we arrive at 170t+4000 to get the linear function f(t) = 170t+4000

The 170 acts like the slope while the 4000 is the y intercept.

Answer:

6 hours

Step-by-step explanation:

Let's highlight/bold some important terms.

A car drives 60 mph. Write and solve an eqaution to find the number of hours it takes the car to travel 360 miles.

So we know Speed multiplied by Time is equal to distance, or commonly known as;

S · T = D

So since we know this, we can substitute the values for the variables.

We know the mph is 60. And that's our speed.

The equation is now 60 · T = D

We know that the total distance the car needs to cover is 360.

The equation is now 60 · T = 360

Now we need to find the time it took.

We divide 360/60 to find out the total number of hours it took, and we get 6.

So the answer is that it took 6 hours to travel 360 miles with a speed of 60 mph.

Answer:

6 hours

Step-by-step explanation:

$30 for transportation plus $20 per ticket to the planetarium.

cost= 30+20N

The second day the members paid

$95 for transportation plus $17 per ticket to theGeology museum.

cost= 95+17N

total cost is

T= 30+20N+ 95+17N

T=30+95+20N+17N

T=125+37N

Any point on the outside edge of a circle from the center of a circle would be the radius, which would be the same distance all the way around. The outer edge of the larger circle goes through the dot labeled B, which is the center of the smaller circle, therefore any distance from B to the outer edge would be the same.

The length of segment BD is the same as the length of segment AB because any distance from B to the outer edge would be the same.

A circle is a shape consisting of all points in a plane that are given the same distance from a given point called the center.

Any point on the outside edge of a circle from the center of a circle will be the radius, which would be the same distance all the way around.

The outer edge of the larger circle goes through the dot labeled B, which means the center of the smaller circle.

Therefore any distance from B to the outer edge would be the same.
