Answer:

The distance between those points is 13.

Step-by-step explanation:

1.    (x2-x1) = (-2 - -7) = 5

2.   (y2-y1) = (-7 - 5) = -12

3.   (5)2 + (-12)2 = 25 + 144 = 169

4.   √169 = 13

Answer:

the given value x=13 is not a solution of the inequality

Step-by-step explanation:

we first need to solve this inequality (can treat the inequality like a normal equation to solve it)

5x-17 > 62

5x > 79

x>(79/5)

keep in mind that (79/5)=15.8

so x needs to be bigger than 15.8 in order to satisfy this inequality.

since 13<15.8 when x=13 it does not satisfy the inequality

therefore the given value x=13 is not a solution of the inequality

i used a calculator

Answer:

Devin has to run 3 more meters than Garrett to complete one lap.

Step-by-step explanation:

Since a running track design is composed of two half circles connected by two straight-line segments, and Garrett is jogging on the inner lane (with radius r) while Devin is jogging on the outer (with radius R), if r = 30 meters and R = 33 meters, to determine how much longer does Devin have to run to complete one lap, the following calculation must be performed:

33 (lane where Devin is jogging) - 30 (lane where Garrett is jogging) = X

33 - 30 = X

3 = X

Therefore, Devin must run 3 more meters than Garrett to complete one lap.

Answer:

Step-by-step explanation:

The cost of the lunch after a 12% of increment will be $9.52. Then the correct options are A, B, and E.

How much any item is given like it was an extent of 100. The proportion can be communicated as a fourth of 100. The expression % deciphers for 100%. It is represented by the person '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

The cost (p) of a lunch unique is $8.50. The eatery builds the cost by 12%.

The total amount of lunch will be given as,

⇒ p + 12% of p

⇒ p + 0.12p

⇒ 1.12p

Put p = $8.50, then the cost is given as,

⇒ 1.12 x $8.50

⇒ $9.52

The expense of the lunch after a 12% of augmentation will be $9.52. Then, at that point, the right choices are A, B, and E.

Step-by-step explanation:

Answer:

1. BC=25

2. DC=30

Step-by-step explanation:

In a parallelogram, pairs of opposite sides are always equal. The side opposite of AD is BC, so if AD=25, BC=25. Likewise, if side AB=30, side DC=30. Of course, this is assuming the shape is a parallelogram. If it is not, there is no way of determining the side lengths.

Answer:

x= 30, y= 90

Step-by-step explanation:

Let the smaller number be x and the greater number be y.

Given that the sum of the 2 numbers is 120,

x +y= 120 -----(1)

The greater number is 3 times the smaller number:

y= 3x -----(2)

Substitute (2) into (1):

x +3x= 120

Simplify:

4x= 120

x= 120 ÷4 (÷4 on both sides)

x= 30

Substitute x= 30 into (2):

y= 3(30)

y= 90

Answer:

Let the first number be x

Then the second number will be 3 × x = 3x

According to the question

3x + x = 120

4x = 120

Taking 4 to RHS

x = 120/4

x = 30

Number are

x = 30

3x = 3(30) = 90

x = 90 - 61

x = 29

Divide the figure into 3 shapes: 2 rectangles and 1 square

Area of rectangle 1: L * W

L = 5, W = 2

2 * 5 = 10 m^2

Area of rectangle 2: L * W

L = 6 + 2 , W = 3

8 * 3 = 24 m^2

Area of square: s^2

2^2 = 4 m^2

Add all them together

10 + 24 + 4 = 38 m^2

Step-by-step explanation:

Area of the top Horizontal Rectangle =

Length x Width

=

[tex](5 + 3 + 2) \times 2 \\ = 10 \times 2 \\ = 20 {m}^{2} [/tex]

Area of the bottom vertical rectangle =

Answer:

Step-by-step explanation:

After 30 minutes Emily and Jennifer charged an equal amount

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

Let us find charges for emily and Jennifer

For Emily

The line passing through points (0, 6) and (6, 8)

Slope =2/6=1/3

y intercept is 6

6=b

Equation is y=1/3x+6

Now let us find for Jennifer (0, 4) and (5, 6)

m=2/5

y intercept is 4

Equation is y=2/5x+4

Now equation both equations

1/3x+6=2/5x+4

1/3x-2/5x=4-6

x(1/3-2/5)=-2

x(5-6)/15=-2

-x/15=-2

x=30

Hence, after 30 minutes Emily and Jennifer charged an equal amount

Properties of a rhombus used to solve the following

(30)

(31)

(32)

Answer:

y-intercept: (0,6)

slope = -2

equation: y = -2x + 6  

Step-by-step explanation:

1) First, identify the y-intercept. The y-intercept is the point at which the line intersects the y-axis. We can see that the line crosses the y-axis at (0,6), so that must be it.

2) Now, find the slope. Pick two points from the line. I chose (0,6) and (3,0). Then, substitute the two points' x and y values into the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]and solve:

[tex]m = \frac{0-6}{3-0}\\m = \frac{-6}{3}\\m = -2[/tex]

So, the slope is -2.

3) With the found information, use the slope-intercept formula [tex]y = mx + b[/tex] to write the line's equation. Substitute values for the [tex]m[/tex] and [tex]b[/tex].

[tex]m[/tex] represents the slope, so substitute -2 in its place. [tex]b[/tex] represents the y-intercept, so substitute 6 in its place. This gives the following equation:

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

Answer:

Step-by-step explanation:

Answer:

x = √6 - 2 , -√6-2

Step-by-step explanation:

We have ,

=> y = x² + 4x - 2

=> x² + 4x - 2 = 0

=> x² + 2(2)(x) - 2 = 0

=> x² + 2(2)(x) +2² - 2² -2 = 0

=> x² + 2(2)(x) + 2² -4-2 = 0

=> ( x + 2 )² -6 = 0

=> ( x +2)² = 6

=> ( x + 2) = √6

=> x + 2 = ±√6

=> x = √6 - 2 , -√6-2

The solution for x in terms of y is x = √y - 2 + √6.

To solve the quadratic equation y = x² + 4x - 2 by completing the square, we need to follow a few steps:

Step 1: Move the constant term to the right side of the equation:

y + 2 = x² + 4x

Step 2: Take half of the coefficient of x and square it. Add the resulting value to both sides of the equation to create a perfect square trinomial on the left side:

y + 2 + (4/2)² = x² + 4x + (4/2)²

y + 2 + 4 = x² + 4x + 4

y + 6 = (x + 2)²

Step 3: Rewrite the equation in vertex form:

(y + 6) = (x + 2)²

The equation is now in the form y = (x - h)² + k, where (h, k) represents the vertex of the parabola.

Therefore, the vertex is (-2, -6), and the equation represents a parabola that opens upward.

To solve the equation (y + 6) = (x + 2)² for x, we need to isolate x. Here's how:

Start with the equation: (y + 6) = (x + 2)²

Subtract 6 from both sides of the equation: (y + 6) - 6 = (x + 2)² - 6

Simplify: y = (x + 2)² - 6

Take the square root of both sides of the equation: √y = √[(x + 2)² - 6]

Simplify: √y = x + 2 - √6

Subtract 2 from both sides of the equation: √y - 2 = x - √6

Rearrange the equation to solve for x: x = √y - 2 + √6
