Answer:

Perpendicular lines intersect forming right angles, which are 90 degrees. Slopes of perpendicular lines are opposite reciprocals, meaning the product of the two slopes is negative 1.

Which did you include in your response?

Perpendicular lines intersect.

They form right angles (90 degrees).

The slopes are opposite reciprocals.

The product of their slopes equals –1.

Bayside Insurance offers two health plans. Under plan A, Giselle

LiRa [457]

Answer:

Step-by-step explanation:

Let x represent the amount of medical bills that Giselle has to pay.

Assume she has over $160 in bills,

it means that

x > 160

Under plan A, Giselle would have to pay the first $110 of her medical bills, plus 35% of the rest. Therefore, she will have to pay for

35/100 × (x - 110) = 0.35(x - 110)

Under plan B, Giselle would pay the first $160, but only 20% of the rest. Therefore, she will have to pay for

20/100 × (x - 160) = 0.2(x - 160)

Therefore, the amount of medical bills that plan B will save is

0.35(x - 110) - 0.2(x - 160) = 0.35x - 38.5 - 0.2x + 32

0.15x + 6.5

Substituting x = 160 into 0.15x + 6.5, it becomes

0.15 × 160 + 6.5 = $30.5

Total bills would be 160 + 30.5 = 190.5

Therefore, Giselle would save $30.5 with plan B if she had more than $190.5 in bills.

Help me please I’ll give a lot of points

Alenkasestr [34]

Answer:

21. B

22. D

23. C

24. y = 3x - 12

Step-by-step explanation:

21. it has to be a positive slope since the graph shows it is increasing/positive slope. Has to be A or B. But it isn't A because where x = 1 1/2, y doesn't equal 0 like the graph shows.

22. It is D if you rewrite the equation starting with y=, so you subtract 2x on both sides to get y = -2x +6. Parallel means slopes are the same, so the slope has to be -2, which is D.

23. The only one that fits the description is C.

24.

in standard form, rearrange the equation so only y is on one side, the rest on the other.

-4x + 2y = 2x - 24

first add 4x on both sides so -4x cancels out on the left hand side.

-4x + 4x + 2y = 2x + 4x - 24

simplify it and get 2y = 6x - 24

divide both side by 2

y = 3x - 12

plot this as shown with arrows on lines.

please give thanks :)
