Are these parallel, perpendicular, or neither?

1 answer:

Answer: I think it’s neither

Explanation:

The line is parallel unless the slope is the same and with a different y-intercept

The line are perpendicular unless the one of the slope is the negative reciprocal of the other.

And both equation didn’t meet any of the requirement.

Simplify (12a^{5}-6a-10a^{3})-(10a-2a^{5}-14a^{4})(12a 5 −6a−10a 3 )−(10a−2a 5 −14a 4 ) . Write the answer in standard form

Answer:

$(12a^{5}-6a-10a^{3})-(10a-2a^{5}-14a^{4}) = 14a^{5}+14a^{4}-10a^{3}-16a$

Step-by-step explanation:

Given

$(12a^{5}-6a-10a^{3})-(10a-2a^{5}-14a^{4})$

Required

Simplify

We have:

$(12a^{5}-6a-10a^{3})-(10a-2a^{5}-14a^{4})$

Open brackets

$12a^{5}-6a-10a^{3}-10a+2a^{5}+14a^{4}$

Collect like terms

$12a^{5}+2a^{5}+14a^{4}-10a^{3}-6a-10a$

$14a^{5}+14a^{4}-10a^{3}-16a$

Hence:

$(12a^{5}-6a-10a^{3})-(10a-2a^{5}-14a^{4}) = 14a^{5}+14a^{4}-10a^{3}-16a$

Polygon stuv is reflected over the x axis and then over the y axis to create wxyz . Which of the following sides are congruent ?

JulsSmile [24]

Answer:

ST and WX are congruent ⇒ first answer

Step-by-step explanation:

∵ S = (-5 , -4) , T = (-3 , -1) , U = (-1 , -3) , V = (-2 , -6)

∵ STUV reflected over the x-axis

∴ S' = (-5 , 4) , T' = (-3 , 1) , U' = (-1 , 3) , V' = (-2 , 6)

∵ S'T'U'V' reflected over the y-axis

∴ S" = (5 , 4) , T" = (3 , 1) , U" = (1 , 3) , V" = (2 , 6)

∵ W = (5 , 4) , X = (3 , 1) , Y = (1 , 3) , Z = (2 , 6)

∴ S"T"U"V" is WXYZ

∴ ST and WX are congruent

Melissa has scored 83 , 84 , 93 , 77 , and 85 on her previous five tests. what score does she need on her next test so that her

pantera1 [17]

83 x 6 = 498

all six of her scores need to equal at least 498 for an 83 average

83 + 84 + 93 + 77 + 85 = 422

498-422 = 76

she needs a 76
