Find Two Consecutive Numbers Whose Sum Is 55
Answer 2

Answer and Step-by-step explanation:

27 and 28.

27 plus 28 equals 55.

To know which numbers to use, we have to find two numbers that would produce a number that would include the digit of the second number in 55. Then, we find numbers that add up to 5, then minus by 1.

find the slope of the line ​

Answers

you would take delta y over delta x
(8-4)/(8-4) and it would be 1.

the slope is 1

Answer:

The slope of the line is: 1

Step-by-step explanation:

Use the equation

[tex] \frac{y2 - y1}{x2 - x1} [/tex]

Use the two sets of points given to you to slve the equation.

Assign the points their variables:

x1 y1 x2 y2

(4, 4) (8, 8)

Insert the numbers into the equation:

[tex] \frac{8 - 4}{8 - 4} [/tex]

Simplify:

[tex] \frac{4}{4} = 1[/tex]

Find the value of x that makes lines u and v parallel, answer needed

Answers

Given:

u and v are parallel lines.

To find:

The value of x.

Solution:

If a transversal line intersect the two parallel lines, then

(1) Corresponding angles are congruent.

(2) Same sides interior angles are supplementary angles and their sum is 180 degrees.

15.

[tex]23x-2=90[/tex]           (Corresponding angles)

[tex]23x=90+2[/tex]

[tex]x=\dfrac{92}{23}[/tex]

[tex]x=4[/tex]

Therefore, the value of x is 4.

16.

[tex](x+106)+(x+86)=180[/tex]         (Same sided interior angles)

[tex]2x+192=180[/tex]

[tex]2x=180-192[/tex]

[tex]2x=-12[/tex]

Divide both sides by 2.

[tex]x=\dfrac{-12}{2}[/tex]

[tex]x=-6[/tex]

Therefore, the value of x is -6.

Which graph represents a geometric sequence? On a coordinate plane, 5 points are plotted. The points are (1, 1), (2, 3), (3, 5), (4, 7), (5, 9). On a coordinate plane, 4 points are plotted. The points are (1, 1), (2, 2), (3, 4), (4, 8). On a coordinate plane, 3 points are plotted. The points are (1, 2), (4, 4), (9, 6). On a coordinate plane, 3 points are plotted. The points are (1, 1), (2, 4), (3, 9).

Answers

Answer:

Graph B is the correct answer. Just in case it is not choice B for you, it's the graph with points (1,1), (2,2), (3,4), and (4,8) in that order. Sadly, the other guy is incorrect and you should not listen to him.

Step-by-step explanation:

The graph that represents a geometric sequence is (b) (1, 1), (2, 2), (3, 4), (4, 8)

What is a geometric sequence?

A geometric sequence is a sequence that has a common ratio

The common ratio of a geometric sequence is calculated as:

[tex]r = \frac{y_2}{y_1}[/tex]

Using the above rule, we have:

[tex]r = \frac{2}{1} = \frac 42 = \frac 84[/tex]

[tex]r =2 =2 =2[/tex]

The above represents option B, and it has a common ratio of 2

Hence, the graph that represents a geometric sequence is (b) (1, 1), (2, 2), (3, 4), (4, 8)

Consider the quadratic function, f(x)=-2x^2+12x+32=0. Select all statements that are true for the function. The value of the discriminant is -112. The value of the discriminant is 20. The value of the discriminant is 400. The function has 1 real solution. The function has 2 real solutions. The function has 2 complex solutions.

Answers

Answer:

Step-by-step explanation:

-2x² + 12x  + 32 = 0

discriminant = 12² - 4(-2)(32) = 400

positive discriminant means there are two distinct real roots

x = [-12 ± √(12² – 4(-2)·32)] / [2·(-2)]

 = [-12 ± √400] / (-4)

 = [-12 ± 20] /(-4)

Answers

Answer:

kaylas thinking of the number 414

Step-by-step explanation:

414 is divisable by 18 (414 divided by 23)

414 is palindrome

414 is one less than a multiple of 5 (415)

Answer:

414

Step-by-step explanation:

The last digit must be 4 or 9 since it is one less than a multiple of five. Then, it says the number must be divisible by 18, and 18 = 2x9. Only 4 is divisible by 2, so four must be the last digit. Since it's a palindrome, the first digit must also be four. Since it also has to be divisible by nine, 4 + 4 = 8, and 8 + 1 = 9.

Nelda needs to wrap a holiday gift box. The box is in the shape of a rectangular prism with the dimensions shown.

Answers

Answer:

416 in²

Step-by-step explanation:

Given that:

Height. h = 4 in

Length = 12 in

Width = 10 in

The surface area of a rectangular prism is obtained using the relation :

Surface Area, S = 2(lw + lh + wh)

S = 2[(10*12) + (10*4) + (12*4))

S = 2(120 + 40 + 48)

S = 2(208)

S = 416 in²
