Step-by-step explanation:

Let's solve your equation step-by-step.

2x+1=−x+4

Step 1: Add x to both sides.

2x+1+x=−x+4+x

3x+1=4

Step 2: Subtract 1 from both sides.

3x+1−1=4−1

3x=3

Step 3: Divide both sides by 3.

Answer:

T = 5.79 (approximated)

Step-by-step explanation:

Using I = PRT/100

where P = The principal amount invested = $5500

R = Rate of Interest =5%

T = Time (in years)

I = Interest = $7,739.05 - $5500 = $2239.05

Substituting the above values in the formula

I = PRT/100 becomes

2239.05 = 7,739.05 * 5 * t / 100 -------- Multiply 100 to both sides

2239.05 * 100 = 100 * 7739.05 * 5 * t / 100

223905 = 7739.05 * 5 * t

223905 = 38695.25t

Divide both sides by 38695.25t

223905/38695.25 = t

5.786369 = t

T = 5.79 (approximated)

Answer:

-8, -6, -4, -2

Step-by-step explanation:

This is the only sequence that is using constant repetition of addition, either adding positive numbers or adding negative numbers (the same positive or negative number). This one that you answered is always adding 2 from the prior number, so -6 = -8+2, -4=-6+2, and so on.

The first one is an odd combo where you add and subtract different values different signs each time, it is not constant addition of the same number.

The second one is multiplication which is not arithmetic, so that means it is constantly being multiplied by 2 each time.

Answer:-8,-6,-4,-2

Step-by-step The last one because it is consistent by adding 2 the other ones ad then subtract or multiply and you can do that so the last on

Answer:

Step-by-step explanation:

Given the -4(-9 + x) = 57, to solve this equation, follow the following steps:

Expend the parentheses at the left hand side using the distributive law.

-4(-9)+(-4x) = 57

Open the bracket by multiplying

+36-4x= 57

Subtract 36 from both sides

36-4x-36 = 57-36

-4x = 21

Divide both sides by -4

-4x/-4 = 21/-4

x = -21/4

From the calculation, we can see that we used 3 operations (multiplication, subtraction and division operations)

The most preferred is multiplication operation because the operation helps to simplify the parentheses using the distributive law in step 1.

[tex]y=-2x-4[/tex]

Step-by-step explanation:

Perpendicular Bisector

The bisector of a segment defined by points (x1,y1) and (x2,y2) must pass by the midpoint of the segment.

The midpoint (xm,ym) is calculated as follows:

[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]

[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]

The endpoints of the segment are (-3,-8) and (5,-4), thus the midpoint M is:

[tex]\displaystyle x_m=\frac{-3+5}{2}=1[/tex]

[tex]\displaystyle y_m=\frac{-8-4}{2}=-6[/tex]

Midpoint: M(1,-6)

Let's find the slope of the given segment. The slope can be calculated with the formula:

[tex]\displaystyle m_1=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\displaystyle m_1=\frac{-4+8}{5+3}=\frac{1}{2}[/tex]

If the bisector is also perpendicular, its slope m2 and the slope of the segment m1 must comply:

[tex]m_1.m_2=-1[/tex]

Solving for m2:

[tex]\displaystyle m_2=-\frac{1}{m_1}=-\frac{1}{\frac{1}{2}}=-2[/tex]

Once we have the slope -2 and the point through which our line must pass (1,-6), we compute the equation in its point-slope form:

[tex]y-y_o=m(x-x_o)[/tex]

[tex]y-(-6)=-2(x-1)[/tex]

Operating

[tex]y+6=-2(x-1)[/tex]

[tex]y+6=-2x+2[/tex]

Rearranging

Step-by-step explanation:

Answer:

The answer is actually 18,000 because for 26 your rounding the nearest ten and for 604 you rounding the nearest hundred so it is 30 x 600 = 18,000

Step-by-step explanation:

The best estimation of 26 × 604 is 18000.

A number system is defined as a system of writing to express numbers.

We need to find estimate of 26 × 604

Approximating a quantity to the required accuracy is known as estimation. This estimation we can do by rounding off the numbers involved in the calculation and get a rough answer.

Now let us round off the number 26 to the nearest tenths.

26 is rounded to 30.

604 is round off to the nearest hundredth which is 600.

Now let us multiply 30 with 600 to get the estimated value of 26 × 604.

30×600

18000

Hence the best estimation of 26 × 604 is 18000.

The correct answer is:  The probability that a customer buys either a mouse or a bird is 25%.

Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e. how likely they are to happen, using it.

Given that, a pet store sells mice, reptiles, and birds,

Let event A = A customer buys a mouse.

Let event B = A customer buys a bird.

We need to tell that,

What does P(A or B) = 0.25 mean in terms of this problem,

So, here the statement given is saying that the 0.25 is the probability that a customer will buy either a mouse or bird,

Hence, the correct answer is:  The probability that a customer buys either a mouse or a bird is 25%.

Answer:

4.5 miles

Step-by-step explanation:

Given

[tex]Middle\ School = (15,13)[/tex]

[tex]Library = (27,9)[/tex]

To solve this, we simply solve for the distance (D) between both points.

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

Where:

[tex](x_1,y_1) = (15,13)[/tex]

[tex](x_2,y_2) = (27,9)[/tex]

[tex]D = \sqrt{(27 - 25)^2 + (9 - 13)^2}[/tex]

[tex]D = \sqrt{(2)^2 + (-4)^2}[/tex]

[tex]D = \sqrt{4 + 16}[/tex]

[tex]D = \sqrt{20}[/tex]

[tex]D=4.472135955[/tex]

[tex]D=4.5[/tex] --- approximated

Since each unit is 1 mile. The distance is 4.5 miles

Answer:

Every polygon is either convex or concave. The difference between convex and concave polygons lies in the measures of their angles. For a polygon to be convex, all of its interior angles must be less than 180 degrees. Otherwise, the polygon is concave.
