The correct answer is option (D).

A triangle is a polygon with 3 sides.

Given the triangles ΔABE and ΔACD.

The triangle ΔABE is a smaller-scaled replica of the triangle ΔACD, therefore, the triangles ΔABE and ΔACD are similar triangles.

Since the triangles are similar, the ratio of their corresponding sides is proportional.

Therefore,

BE/CD = AB/AC

Or, BE = CD· (AB/AC)

Hence, the correct answer is option (D).

Answer:

The graphs are missing, but we can find the inequality for this problem:

She has $60.

The price of a T-shirt is $10, the price of a sweatshirt is $14.

If T is the number of T-shirts she buys, and S is the number of sweatshirts that she buys, we have:

T + S ≥ 5 (because she wants to buy at least 5 items)

T*$10 + S*$14 < $60 (because she wants to spend under $60)

Those two inequalities define the number of T-shirts and sweatshirts that she can buy.

The intersection portion of the graph represents the number of T-shirts and sweatshirts Regina can buy to meet her goal.

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than, known as inequality.

We have:

Regina is shopping for clothes, and she sees that T-shirts are marked at $10 each and sweatshirts are marked at $14 each.

Here, graph are missing.

Let's suppose the number of T-shirts is T and the number of sweatshirts is S.

T + S ≥ 5 (because she wants to buy at least 5 items)

10T + 14S < 14 (spending under $60)

If we plot the above inequality on a coordinate plane.

Thus, the intersection portion of the graph represents the number of T-shirts and sweatshirts Regina can buy to meet her goal.

Answer:

x = -2

Step-by-step explanation:

2x + 5 = 1 ( subtract 5 from both sides )

2x = 1-5

2x = -4 ( divide both sides by 2 )

2x ÷ 2 = -4 ÷ 2

x = -2

Answer: x = -2

Step-by-step explanation: To solve for x, we must first isolate the term containing x which in this problem is 2x.

Since 5 is being added to 2x, we subtract 5

from both sides of the equation to isolate the 2x.

On the left, the +5 and -5 cancel out and on the right, 1 - 5 is -4.

So we have 2x = -4.

Now we can finish things off by just

dividing both sides of the equation by 2.

On the left, the 2's cancel and on the right, -4 divide by 2 is -2.

So x = -2.

Answer:

2x + y - 4 = 0

Step-by-step explanation:

slope = -2

y = mx + b

2 = -2(1) + b

4 = b

y = -2x + 4

2x + y - 4 = 0

Answer:

the answer is 2x + y - 4 = 0

Step-by-step explanation:

me and my friend did the math and got 2x + y - 4 = 0

Answer:

speed = distance/time

distance = 60 miles

time = 1.5 h

speed = 60/1.5

= 40 miles per hour

so the answer in the pic is the correct answer

The equation of line is y = 40x and the unit rate of speed of travel is given by A = 40 mph

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first point be P ( 0 , 0 )

Let the second point be Q ( 1.5 , 60 )

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 60 / 1.5 )

Slope m = 40 miles per hour

So , the speed of the travel is 40 mph

And , the equation of line is y - y₁ = m ( x - x₁ )

y = 40x , where x is the number of hours

Hence , the speed of the travel is 40 miles per hour

Answer:

The answer is 2

Step-by-step explanation:

Answer:

Correct option: C -> 2

Step-by-step explanation:

The first equation is:

[tex]x^2+y^2=363[/tex]

And the second equation is:

[tex]x-y+1=0[/tex]

From the second equation, we have:

[tex]y = x + 1[/tex]

Using this value of y in the first equation, we have:

[tex]x^2 + (x+1)^2 = 363[/tex]

[tex]x^2 + x^2 + 2x + 1 = 363[/tex]

[tex]2x^2 + 2x= 362[/tex]

[tex]x^2 + x - 181 = 0[/tex]

Calculating the discriminant Delta, we have:

[tex]\Delta = b^2 - 4ac = 1 + 4*181 = 725[/tex]

We have [tex]\Delta > 0[/tex], so we have two real values for x, therefore we have two solutions for this system.

Correct option: C.

(If the system of equation is actually:

[tex]x^2+y^2=36[/tex]

[tex]3x-y+1=0[/tex]

We would have:

[tex]y = 3x + 1[/tex]

[tex]x^2+(3x+1)^2=36[/tex]

[tex]x^2+9x^2+6x+1=36[/tex]

[tex]10x^2+6x-35=0[/tex]

[tex]\Delta = 36 + 1400 = 1436[/tex]

We also have [tex]\Delta > 0[/tex], so we have two solutions for this system.

First state the equation:

7x+15=30

Bring 15 to the other side of the equation, making the (+) to (-)

So,

7x+15= 30

7x= 30-15

7x= 15

Bring 7 to the other side, it'll become 1/7

x= 15*1/7

= 15/7

Answer:

She subtracted 3.4 on the left and added 3.40 on the right

Step-by-step explanation:

3.40 + 0.85 x = 5.27

Subtract 3.40 from each side  

3.40 -3.40+ 0.85 x = 5.27-3.40

.85x = 5.27 - 3.40

.85x =1.87

Divide by .85

.85x/.85 =1.87/.85

x = 2.2

Answer:

(C) Carina should have subtracted 3.40 from 5.27.

Step-by-step explanation:

Answer:

a) 10.7 cm

b) 11.6 cm

c) 29.9 cm²

Step-by-step explanation:

a) sin(α)/a = sin(β)/b

sin(∠BCD)/BD = sin(DBC)/DC

sin(41°)/BD = sin(55°)/13.4

BD = 13.4*sin(41°)/sin(55°) = 10.73 cm ≈ 10.7 cm

b) From ΔBCD , ∠BDC = 180-(41+55) = 84°

∠ABD and ∠BDC are alternate interior angles, so they are congruent, and

∠ABD = ∠BDC  = 84°

AD²= AB² + BD² - 2*AB*BD*cos (∠ABD) =

= 5.6² + 10.73² - 2*5.6*10.73*cos(84°) = 133.93 cm²

AD =√(133.93) ≈11.6 cm

c) Area(ADB) = (1/2)*AB*BD*sin(∠ABD)=(1/2)*5.6*10.73*sin(84°) ≈ 29.9 cm²

Answer:

Answer:

x = 27°

Step-by-step explanation:

Because of the two parallel lines, we can conclude that

corner DAB = corner FDE = 2x

In ∆DAB

Corner DAB = 2x

Corner BDA = 2x (given)

Corner ABD = 72 (given)

The sum of three corners in any trianle, adds up to 180°.

So if one corner is 72° and the other two corners are the same, then the two corners together, must be 180-72 = 108°.

For each corner that is 108/2= 54

so corner BDA = 54° and also corner DAB = 54°.

Given was BDA = 2x and BDA = 54°

so 2x = 54°

then x = 27°

Complete question is:

Nancy is checking to determine if the expressions x+4+x and 6+2x-2 are equivalent. When x=3 , she correctly finds that both expressions have a value of 10. When x = 5, she correctly evaluates the first expression to find that x + 4 + x = 14. What about the second expression?

Answer:

when x = 5; both expressions are equivalent and equal to 14

Step-by-step explanation:

We are told the expressions are:

(x + 4 + x) and (6 + 2x - 2).

We are also told that when x = 3,both expressions are equal and have a value of 10 each.

Now, when x = 5; we are told the expression (x + 4 + x) has a value of 14.

So when x = 5,let's find the value of the second expression by putting 5 for x in (6 + 2x - 2);

So, we have; 6 + 2(5) - 2 = 6 + 10 - 2 = 14

So when x = 5; both expressions are equivalent and equal to 14
