The answer is definitely answer 1,60,-20 divide it by 2 and u get -10,30, its put in different ways with the negative first because your supposed to put ordered pairs in an order of Rise Over Run, so -10 would go first and 30 would go second, the dot thats given might confuse u because its not put in to Rise over run, it should be marked as -20,60 instead its marked as 60,-20.

Given △MON≅△PQR with MO=20 , MN=32 and PR=3x−10. Find the value of x.<br><br> show your work

aliya0001 [1]

Answer:

$x=14$

Step-by-step explanation:

we know that

If two figures are congruent, then its corresponding sides and its corresponding angles are congruent

In this problem

△MON≅△PQR

corresponding sides

MO≅PQ

MN≅PR

ON≅QR

corresponding angles

∠M≅∠P

∠O≅∠Q

∠N≅∠R

therefore

MN=PR

substitute the given values

$32=3x-10$

solve for x

$3x=32+10$

$3x=42$

$x=14$

A line passes through the points (p, a) and (p, –a) where p and a are real numbers. If p=0, what is the y-intercept? Explain you

Vsevolod [243]

The slope of the line passing through the points A(a, b), and B(c, d), is given by
$\displaystyle{ m=\frac{d-b}{c-a},$

thus, the slope of the line through <span>points (p, a) and (p, –a) is

</span> $\displaystyle{ m=\frac{-a-a}{p-p}=\frac{-2a}{0}.$

When applying the slope formula results in division by zero, this means that the line is a vertical line.

This could have also been noticed directly, since the line contains 2 points with the same x-coordinate.

The equation of this line is x=p, since the x-coordinate is always p, no matter what y is.

If p=0, then the equation of the line is x=0, which is the y-axis itself. In this case, the y-intercept is the whole y-axis.

Answer: The whole y-axis.

Bradley wants to build a shop in his backyard. He knows the shop will be a rectangular shaped building. He wants the length of t

grigory [225]

Answer:

A = 6x² + 97x + 391

Step-by-step explanation:

Given that,

The length of the shop, l = (3x+23)

The width of the shop, b = (2x+17)

The expression for the area of the shop is given by :

A = lb

Put all the values,

A = (3x+23) × (2x+17)

= 6x² +51x+46x +391

= 6x² + 97x + 391

Hence, the expression for the area of the shop is equal to 6x² + 97x + 391.

Medical researchers are studying a certain genetic trait found in two populations of people, W and X. From an independent random

nadya68 [22]

Answer:

If the proportions of all people who carry the trait are the same for both populations, the probability of observing a sample difference of at least 0.22 is 0.03

Step-by-step explanation:

Given the hypothesis :

H0 : pW = pX

Ha : pW > pX

W - X = 0.22

Pvalue = 0.03

Since the Pvalue gives the probability of obtaining a value or result figure which is atleast as extreme as the observed value. The observed value here is 0.22 resulting from the difference in W and X (W - X).

This can thus be interpreted to mean ; going by the Null (difference between W and X) ; the probability of obtaining a value of atleast 0.22 as difference is 0.03
