Answer 1

Answer:

Step-by-step explanation:

Answer 2

Step-by-step explanation:

area of rectangle

height×base

(2x-5)(2x-2)=

=4x^2-4x-10x+10

=4x^2-14x+10

(we get quadratic equation)

a=4 b=-14 c=10

firat find discriminant with formula:

D=b^2-4ac(-14)^2-(4×4×10)=196-160=36

now find x1 and x2 with formula:

X=(-b±√D)/2a

x1=(14+√36)/8=20/8=2.5

x2=(14-√36)/8=8/8=1

lets put values :

if we put x2 value as a base, which is 1 in given height and base, we will get 2(1)-2=0. measure of amy side can't be 0.

and if we put x2 in height, it will give us zero.

so no matter which one we put as value. we will get 0cm^2. so i think it cant be detected. im sorry if im wrong

Help me please find the slope and y-intercept

Answers

Answer:

Slope is 2.15

y-intercept is 2

Step-by-step explanation:

We need to find slope and y-intercept of the graph given.

The formula used to find slope is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

Looking at the graph, we can find 2 points

Point 1 : (0,-2)

Point (2): (2,-2.3)

Now putting values and finding slope:

We have: [tex]x_1=0, y_1=-2, x_2=2, y_2=-2.3[/tex]

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{2.3-(-2)}{2-0}\\ Slope=\frac{2.3+2}{2}\\ Slope=\frac{4.3}{2}\\Slope=2.15[/tex]

So, we get slope = 2.15

Now, finding y-intercept

y-intercept can be found if we put x =0

Looking at the graph, when x =0, y = 2

So, y-intercept is 2

Answers

Answer:

(C). 54°

Step-by-step explanation:

m∠3 + m∠4 = 90°

m∠1 = m∠4 = 2x + 8

(4x - 2)° + (2x + 8)° = 90°

4x - 2 + 2x + 8 = 90

6x + 6 = 90

6x = 84

x = 14

m∠6 = m∠3 = 4(14) - 2 = 54°

we have:

y ≤ 2

y ≥ 2

x > 2

y > 2

The graph is limited by a line; y = 2 (red line).

The part corresponds to the part in which y > 2.

The line is continuous, so 2 is also included in the interval

y ≥ 2

Then to find if it is "less than" (<) or "less than or equal to" (≤):

Since the line that limits this interval. The line is y = x, it is a dotted line, the extreme is not included.

Why did some World War I veterans demand their government bonus in 1932 instead of waiting until 1945, when it was promised to be paid?

The Bonus Army was a group of 43,000 demonstrators – made up of 17,000 U.S. World War I veterans, together with their families and affiliated groups – who gathered in Washington, D.C. in mid-1932 to demand early cash redemption of their service certificates. Organizers called the demonstrators the "Bonus Expeditionary Force", to echo the name of World War I's American Expeditionary Forces, while the media referred to them as the "Bonus Army" or "Bonus Marchers". The demonstrators were led by Walter W. Waters, a former sergeant.

Mrs. Carter puts a variety of wrapped chocolate candies into a bag. There

of the bag without looking, and replace the candy after each draw, how

bag?
A. 4 Students
B. 5 Students
C. 15 Students
D. 60 Students

Answers

Answer:

4

there is only 4 golden wrapped candies

Answer:

B. 5 students

Step-by-step explanation:

There are 12 different candies to pick from, only 4 of which are gold. To find the chances of getting gold you divide 4 gold by the total of 12. This gives you a 1/3 chance of getting gold.

Since the chances are the same each time, you should expect 1/3 of the students to pick gold. So, divide 15 by 3(or multiply 15 by 1/3, same thing), to get 5 students.

Which of these equations has a solution of x = 2? Select three that apply. A 6(2x – 1) = 4 + 7x B 10 – 3x = –2(x + 4) C –3(7 – 2x) = –1 – 4x D 7x + 12 = 2(4x – 5) E –5(x + 1) = –4 – 7x F 8x + 11 = 9(5 – x)

Answers

Answer:

x = 2 for a, c, and f

Step-by-step explanation:

a)

6(2x - 1) = 4 + 7x

12x - 6 = 4 + 7x

5x = 10

x = 2

b)

10 - 3x = -2(x + 4)

10 - 3x = -2x - 8

18 = x

c)

-3(7 - 2x) = -1 - 4x

-21 + 6x = -1 - 4x

10x = 20

x = 2

d)

7x + 12 = 2(4x - 5)

7x + 12 = 8x - 10

22 = x

e)

-5(x + 1) = -4 - 7x

-5x - 5 = -4 - 7x

2x = 1

x = 1/2

f)

8x + 11 = 9(5 - x)

8x + 11 = 45 - 9x

17x = 45 - 11

Find the measure of each angle.
The measure of one interior angle of a parallelogram is 0.25 times the measure of another angle.

Answers

Answer:  Two of the angles are 144°  The other two angles are 36°

Step-by-step explanation: The sum of the angles of a parallelogram is 360°

There are two pairs of equal angles.

Using that information, we can create an equation

2x + 2(0.25x) = 360

2x + .5x = 360

2.5x = 360 . Divide both sides by 2.5 to find the value of x:

x = 144° Substitute 144 for x in the expression for the smaller angles

.25(144) = 36°

The measure of the angles in the parallelogram are 144 and 36 degrees.

What is a parallelogram?

A parallelogram is a quadrilateral with two pairs of parallel sides. The opposite sides of a parallelogram are of equal length and the opposite angles are also equal.

Angles in a parallelogram

a + b + c + d = 360

Opposite angles are equal, so

2a + 2(0.25a) = 360

2a + 0.5 = 360

2.5a = 360

a = 360/ 2.5

a = 144

the other angle = 180 - 144 = 36 degrees
