Write this equation in slope intercept form 3x+2y=4

Please help me with this !! I REALLY need to have good grades because...Back story I had my phone and I broke it and I can't get

Answer:

Transformation include reflecting and dilating of points

The scale factor from PQR to P'Q'R' is 1/4

The coordinates of P"Q"R" are P"=(-1,0) Q"=(0,-1) R"=(2,-1) .

PQR and P′'Q′'R′' are not congruent

The points are given as:

p=(4,0)

q=(0,-4)

r=(-8,-4)

p'=(1,0)

q'=(0-1)

r'=(-2,-1)

(a)The scale factor from PQR to P'Q'R

To do this, we make use of corresponding sides QR and Q'R

So, the scale factor (k) is:

k=q'r'/qr

k=2/8

k=1/4

(b) The coordinates of P"Q"R from reflecting P'Q'R' about the y-axis

The rule of this transformation is:

(x,y)--------(-x,y)

So, we have:

p"=(-1,0)

q"=(0,-1)

r"=(2,-1)

(c) Are triangle PQR and P"Q'R" congruent?

No they are not

This is so because

PQR was dilated by 1/4 to get P'Q'R

P'Q'R' and P"Q"R" are congruent

Hence, PQR and P′'Q′'R′' are not congruent

it rained nine days in the month of april .based on this ,what is the probaility that is does not rain on the first day of may?

attashe74 [19]

<h3>Answer: 7/10</h3>

==========================================================

Explanation:

There are 30 days in April. Since it rained 9 of those days, the empirical probability of it raining in April is 9/30 = (3*3)/(3*10) = 3/10.

If we assume that the same conditions (ie weather patterns) hold for May, then the empirical probability of it raining in May is also 3/10. By "raining in May", I mean specifically raining on a certain day of that month.

The empirical probability of it not raining on the first of May is therefore...

1 - (probability it rains)

1 - (3/10)

(10/10) - (3/10)

(10-3)/10

7/10

We can think of it like if we had a 10 day period, and 3 of those days it rains while the remaining 7 it does not rain.

Solve x^2 x=0.factorise.

Semenov [28]

$x^2\pm x=0\\\\x(x\pm1)=0\iff x=0\ or\ x\pm1=0\\\\\boxed{x=0\ or\ x=\mp1}\\\\if\ x^2+x=0\ then\ x=0\ or\ x=-1\\if\ x^2-x=0\ then\ x=0\ or\ x=1$

The measure of the vertex angle of an isosceles triangle is 92. Find the measure of a base angle

Andrej [43]

Answer:

44°

Step-by-step explanation:

The sum of the angles in a triangle = 180°

In an isosceles triangle the base angles are equal, thus

base angle = $\frac{180-92}{2}$ = $\frac{88}{2}$ = 44°
