Answer 1

Answer:

a. x = 5, AB = 14, BC = 8

Step-by-step explanation:

✔️Both triangles are similar, therefore their side lengths are proportional to each other.

Thus:

[tex] \frac{2x + 4}{x + 3} = \frac{7}{4} [/tex]

Cross multiply

[tex] 4(2x + 4) = 7(x + 3) [/tex]

[tex] 8x + 16= 7x + 21 [/tex]

Collect like terms

[tex] 8x - 7x = -16 + 21 [/tex]

[tex] x = 5 [/tex]

✔️AB = 2x + 4

Plug in the value of x

AB = 2(5) + 4

AB = 14

✔️BC = x + 3

Plug in the value of x

BC = 5 + 3

BC = 8

Use the Zero Product Property to find the x-intercepts for x^2+6x=y

Answers

Answer:

[tex]x=0\ or\ x =-6[/tex]

Step-by-step explanation:

Given

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

Required

Determine the x intercepts

To get the x intercepts, we simply set y to 0

Substitute 0 for y;

[tex]x^2+6x=0[/tex]

Factorize:

[tex]x(x +6) = 0[/tex]

Apply zero product property

[tex]x=0\ or\ x + 6 =0[/tex]

[tex]x=0\ or\ x =-6[/tex]

Which one of the following reasons does NOT explain why 2x + 3y ≠ 5xy?

Answers

Answer:

Since 2 and 3 are factors, they should be multiplied to get 6xy.

Step-by-step explanation:

The solution is Option B.

Since 2 and 3 are factors, they should be multiplied to get 6xy and the equation is False

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

2x + 3y ≠ 5xy

a)

If you substitute 4 for x and 5 for y in the expression 2x+3y, it does not equal 5(4)(5)

Substituting the value of x = 4 and y = 5 in the equation , we get

2 ( 4 ) + 3 ( 5 ) ≠ 5 ( 4 ) ( 5 )

8 + 15 ≠ 100

23 ≠ 100

Therefore , the statement is True

b)

Since 2 and 3 are factors, they should be multiplied to get 6xy

2x ( 3y ) = 6xy

But the equation does not equals 6xy

Hence , the statement is False and does not explain the given equation

c)

x and y are not like terms

The statement is true because the variables x and y are not the same

Therefore , the statement is True

d)

Adding x and y is not the same as multiplying x and y

The value of the equation x + y = x + y and on multiplying x and y = xy

And , x + y ≠ xy

Therefore , the statement is True

Hence , the equation 2x ( 3y ) = 6xy is False

Traveling from City 1 to City 2, a pilot planned a southeast course along the path labeled d. Instead, a storm forced the pilot to travel 32 miles south, then 24 miles east to reach City 2. How many extra miles was the pilot forced to fly?




A. 13 mi.

B. 14 mi.

C. 16 mi.

D. 17 mi.

Answers

The extra miles the pilot was forced to fly, found using Pythagorean Theorem was 16 miles. The correct option is therefore;

C. 16 mi

What does Pythagorean Theorem state?

Pythagorean theorem can be stated as follows; The square of the length of the hypotenuse side of a right triangle is equivalent to the sum of the square of the lengths of the other two sides.

The direction the pilot planned initially = A southeast course

The direction the storm forced the pilot to travel = 32 miles south then 24 miles east

The number of extra miles the pilot is forced to fly = Required

Taking the original path as a straight line, and the destination arrived at being that of the new destination, we get by using Pythagoras Theorem

Direct distance, d₁ = √(32² + 24²) = 40The direct distance from City 1 to City 2 = 40 miles

The new distance can be obtained by the scalar addition of the individual distances as follows;

d₂ = 32 + 24 = 56

The new distance traveled, d₂ is 56 miles

The number of extra miles, Δd, is therefore;

Δd = d₂ - d₁

Which indicates that we have;

Δd = 56 miles  - 40 miles = 16 milesThe number of extra miles the pilot was forced to fly is Δd = 16 miles

Answer:

a. x = 5/2

b. y = 16.5

c. z = 12

Step-by-step explanation:

Answer:

1) x = 2.5

b) y = 12.9

c) z = 12

d) 2.75 = w or 2[tex]\frac{3}{4}[/tex] = w

e) t = 4

Step-by-step explanation:

a)

2x = 5

divide both sides of the equation by 2

2x/2 = 5/2

x = 5/2

x = 2.5

b)

y + 1.8 = 14.7

subtract 1.8 from both sides of the equation

y + 1.8 - 1.8 = 14.7 - 1.8

y = 14.7 - 1.8

y = 12.9

c)

6 = 1/2z

divide both sides by 1/2 or multiply both sides by 2

6*2 = 1/2z * 2

6*2 = z

12 = z

d)

3.25 = 0.5 + w

subtract 0.5 from both sides of the equation

3.25 - 0.5 = 0.5 + 2 - 0.5

3.25 - 0.5 = w

2.75 = w

or

2[tex]\frac{3}{4}[/tex] = w

e)

t = 10/2.5

Jamie receives 15% commission on magazine subscriptions. One week her sales totaled $860. What was her commission?

Answers

Given:

Jamie receives 15% commission on magazine subscriptions.

One week her sales totaled $860.

To find:

Her commission.

Solution:

We have,

Total sales of one week = $860

Rate of commission = 15%

Now,

[tex]Commission=\dfrac{15}{100}\times 860[/tex]

[tex]Commission=\dfrac{15}{10}\times 86[/tex]

[tex]Commission=\dfrac{1290}{10}[/tex]

[tex]Commission=129[/tex]

Therefore, the amount of commission is $129.
