Welll, the angles should be supplemeentary since they are a linear pair, so the correct answer shoudl be something nlike

2x+x+75=180
3x+75=180
x+25=60
x=35

so the answers are
A. solution B is incorrrect
B. the 2nd to last option (they are a same-side interior angle, which mean that they are supplemtnary... The angle measures should not be set equal to each other)

The correct answers are:

Part A: Solution A is incorrect.

Part B: The labeled angles are same-side interior angles, which are supplementary. The measures of supplementary angles total 180 degrees, so x + 75 plus 2x should be set equal to 180.

Explanation:

The two angles listed are same-side interior angles. This is because they are inside the block of parallel lines and on the same side of the transversal (the side of the trapezoid). Same-side interior angles are supplementary, so these angles must be supplementary. This means their sum is 180°:

2x+x+75 = 180

Which situation represents a proportional relationship?

ss7ja [257]

Answer:

Step-by-step explanation:

A proportional relationship is defined by a linear equation whose y-intercept is zero.

Thus, we immediately reject answers A, B, and C because all involve a non-zero y-intercept.

D is the correct answer. We combine the unit cost $1.75/lb with the shipping fee $0.16/lb, obtaining a unit cost of $1.91/lb. The desired linear equation with zero y-intercept is then

C(x) = ($1.91/lb)x, where x is the number of pounds of avocados sold.

What is the discriminant of 3x2 + 6x = 2?

Softa [21]

Answer:

Discriminant is 60

Step-by-step explanation:

the discriminant of $3x^2 + 6x = 2$

To find discriminant , first we write the equation in the form of

$ax^2+bx+c=0$

$3x^2 + 6x = 2$

Subtract 2 on both sides

$3x^2 + 6x-2=0$

a=3, b=6, c=-2

Formula for discriminant is $b^2-4ac$

Plug in the values

$b^2-4ac=(6)^2-4(3)(-2)=60$

Discriminant is 60

Answer:

under coverage

Step-by-step explanation:

From the given information we can say that 2% of households have no telephone, 14% have only cell phones, and another 25% have unlisted telephone numbers. Since, the facility is available some part of population and not available to the whole population so, clearly its an examples under coverage.
