Using the figure below, identify the measurements of Angle 3 and Angle 8. Pls help

katrin2010 [14]

Answer:

Angle 3 is 75 degrees

Angles 8 is 105 degrees

Step-by-step explanation:

Angle 3: One line t, angle 3 and the one measure 105 are supplementary and equal to 180 degrees. Subtract 105 from 180.

Angles 8: The angle that measures 105 and angle 8 are alternate exterior angles. This means both angles are equal.

Hope this helps!

John needs to take a cab uptown and only has y dollars. The cab company charges a flat fee of $2.25 plus $0.55 per mile. If John

Dvinal [7]

Answer:

Maximum distance covered by John = 22.8 miles

Step-by-step explanation:

The cab company charges a flat fee of $2.25 plus $0.55 per mile.

Amount of money John has = $y

Let the number of miles traveled in $y = x miles

If John finds a cab charging same fee and $0.45 per mile,

y ≤ 2.25 + 0.45x

y - 2.25 ≤ 0.45x

$x\leq \frac{(y-2.25)}{0.45}$

Therefore, inequality representing the maximum distance covered by John,

$x\leq \frac{(y-2.25)}{0.45}$

If, y = $12.52

$x\leq \frac{(12.52-2.25)}{0.45}$

x ≤ 22.8 miles

Therefore, John will be able to travel the maximum distance = 22.8 miles.

If a=5x^2+3x-7 and b=-3x^2-7x+5 find b-a

uranmaximum [27]

Answer:

-8x^2-10x+12

Step-by-step explanation:

first set up the problem:

(-3x^2-7x+5)-(5x^2+3x-7)

Since you are subtracting you need to distribute the (-) sign:

(-3x^2‐7x+5)(-5x^2-3x+7)

Now just combine like terms

-3x^2+(-5x^2= -8x^2

(-7x+(-3x= -10x

5+7= 12

set answer in standard form:

-8x^2-10x+12

Y= 3x-1 2x+6=y substitution method

vfiekz [6]

Answer: (7, 20)

Concept:

There are three general ways to solve systems of equations:

Elimination
Substitution
Graphing

Since the question has specific requirements, we are going to use substitution to solve the equations.

Solve:

Given equations

y = 3x - 1

2x + 6 = y

Substitute the y value since both equations has isolated [y]

2x + 6 = 3x - 1

Add 1 on both sides

2x + 6 + 1 = 3x - 1 + 1

2x + 7 = 3x

Subtract 2x on both sides

2x + 7 - 2x = 3x - 2x

$\boxed{x=7}$

Find the value of y

y = 3x - 1

y = 3(7) - 1

y = 21 - 1

$\boxed{y=20}$

Hope this helps!! :)
