which is perpendicular to the line x-2y=2
Answer:
y=-2x+5
Step-by-step explanation:
x-2y=2
2y=x-2
y=(x-2)/2
so the slope is 1/2
for lines to be perpendicular m1m2=-1 so the line must have a slope satisfying the condition
(1/2)m=-1
m=-2
the only line with a slope of -2
If is wrong i'm sorry

Given:
x = 70y = 106Find: Z to two decimal places
[tex] {a}^{2} + {b}^{2} = {c}^{2} \\ {x}^{2} + {z}^{2} = {y}^{2} \\ {70}^{2} + {z}^{2} = {106}^{2} \\ 4900 + {z}^{2} = 11236 \\ {z}^{2} = 11236 - 4900 = 6336 \\ z = \sqrt{6336} = 79.60[/tex]
what is the answer
Answer:
9
Step-by-step explanation:
Since 12 divided by 4 is 3, that is the constant. So 3 times 3 is 9

Answer:
3*r = 3
Step-by-step explanation:
[tex]\dfrac{24}{r}=3\\\\24 = r*3\\\\\dfrac{24}{3}=r\\\\6 = r[/tex]6 is a solution.
[tex]3*r=3\\\r =\dfrac{3}{3}\\\\r = 1\\[/tex]
6 is not a solution.
[tex]7r = 42\\\\r =\dfrac{42}{7}\\\\r = 6[/tex]
6 is a solution
Answer:
My best answer is A
Step-by-step explanation:
if you plug in 6 for r, it doesn't work for A.
B is hard to see so can't tell
C works with r=6, so it's not C
and D works as well, so it's not D

Write 7.5 -102 in standard form.
Answer:
-94.5
Step-by-step explanation:
7.5 less 102 is equivalent to the negative of 102 less 7.5: -(102 - 7.5) = -94.5.
It is not strictly necessary to reverse the order of the numbers as shown above, but 102 - 7.5 is more famliar (and thus easier to deal with) than
7.5 - 102.
A group of engineers developed a new design for a steel cable. They need to estimate the amount of weight the cable can hold. The weight limit will be reported on cable packaging. The engineers take a random sample of 44 cables and apply weights to each of them until they break. The 44 cables have a mean breaking weight of 778.1 lb. The standard deviation of the breaking weight for the sample is 15.5 lb.
Find the 99% confidence interval to estimate the mean breaking weight for this type cable.

Solve for x: x - 10 = -12
Answer:
x = -2
Step-by-step explanation:
Step 1: Add 10 to both sides.
[tex]x - 10 + 10 = -12 + 10[/tex] [tex]x = -2[/tex]Step 2: Check if solution is correct.
[tex]-2 - 10 = -12[/tex] [tex]-12=-12[/tex]Therefore, x = -2.

Step-by-step explanation:
The product of polynomials is 6x³-33x²+45x-6. Therefore, option C is the correct answer.
What is product of polynomials?To multiply two polynomials: multiply each term in one polynomial by each term in the other polynomial. Add those answers together, and simplify if needed.
Given that, (3x-6)(2x²-7x+1).
By using distributive property, we get
3x(2x²-7x+1)-6(2x²-7x+1)
= 6x³-21x²+3x-12x²+42x-6
= 6x³-21x²-12x²+3x+42x-6
= 6x³-33x²+45x-6
Therefore, option C is the correct answer.

The polynomial of degree 5, P(2), has leading coefficient 1, has roots of multiplicity 2 at x = 4 and
x = 0, and a root of multiplicity 1 at 3 3.
Find a possible formula for P(x).
P(x)
Answer:
[tex]P(x)=x^{5} +x^{4} -5x^{3} +3x^{2}[/tex]
Step-by-step explanation:
Each root corresponds to a linear factor, so we can write:
[tex]P(x)=x^{2} (x-1)^{2} (x+3)\\=x^{2} (x^{2} -2x+1(x+3)\\\\=x^{5} +x^{4} -5x^{3} +3x^{2}[/tex]
Any polynomial with these zeros and at least these multiplicities will be a multiple (scalar or polynomial) of this [tex]P(x)[/tex]
Footnote
Strictly speaking, a value of [tex]x[/tex] that results in [tex]P(x)=0[/tex] is called a root of
[tex]P(x)=0[/tex] or a zero of [tex]P(x)[/tex] . So the question should really have spoken about the zeros of [tex]P(x)[/tex] or about the roots of [tex]P(x)=0[/tex]

WILL CHOOSE BRAINLIEST:Directions: From the graph, write the linear equation in slope-intercept form
Answer:
y = -2/3x - 2
Step-by-step explanation:
Picking two points on the line: (0,-2) & (-3,0)
Using the slope formula:
[tex]\frac{x2-x1}{y2-y1}[/tex]
= (0-(-2))/(-3-0)
= 2/-3
= -2/3
y = -2/3x + c
Subsituting (0,-2) into 'y = -2/3x+c':
-2 = 0 + c
c= -2
Hence,
y = -2/3x -2
