Hello, happy Friday, I am just here with some geometry questions.

Mathematics
1 answer:
Marina CMI [18]3 years ago
8 0

Answer:

The scale factor is 3/2.

Step-by-step explanation:

Let's use the side PQ.

The original length was 8 units.

And the new length is 12 units.

Let the scale factor be k. Therefore:

8k=12

By dividing both sides by 8, we can see that our scale factor from ΔPQR to ΔP'Q'R' is:

\displaystyle k=\frac{12}{8}=\frac{3}{2}

4. Which of the following describes all the solutions of -4x + 2y > 12 when y = 4?
Alja [10]

Answer:

Option B is correct

Step-by-step explanation:

Given data

We are given the expression

-4x + 2y > 12

We want to substitute y=4 into the expression

-4x + 2(4) > 12

-4x + 8 > 12

-4x> 12-8

-4x> 4

divide both sides by -4

x> 4/-4

x>-1

Hence option B is correct

X-20 = y+20<br>2Y - 44 = X + 22<br>​
nordsb [41]

X-20 = Y+20........    X-Y = 20+20........

X-Y = 40

AND

2Y-44=X+22.............   Y-X= 44+22

Y-X=66

NOW, LET'S FIND X AND Y FROM THESE TWO EQUATIONS....

X-Y =40

Y-X= 66

IF WE COLLECT .......     2Y = 106 AND Y = 53

THEN, USE Y IN ANY EQUATIONS FOR FINDING X

X-53 = 40 ..... X= 53+40 .......... X= 93

X= 93

Y=53

Parabola passes through the points (0,5), (1,4), and (2,5). What function does the graph represent?
AfilCa [17]

Answer:

x^2 - 2x + 5 = 0.

Step-by-step explanation:

The (0, 5) is the point where the parabola passes through the y axis (where x = 0), so we can write the equation as

y = ax^2 + bx + 5   where a and b are constants to be found.

Also, since (1, 4) and (2, 5) are points on the curve, substituting, we have the system:

a(1)^2 + 1b + 5 = 4

a(2)^2 + 2b + 5 = 5

Simplify these 2 equations:

a  + b  =  -1  .................(1)

4a + 2b = 0..................(2)

Multiply the first equation by -2:

-2a - 2b = 2 .................(3)

Add (2) + (3):

2a = 2

a = 1.

Substitute a = 1 into (2):-

4*1 + 2b = 0

2b = -4

b = -2.

Angle AOC has what measurement according to the protractor? A. 150° B. 50° C. 30° D. 130°
maxonik [38]

Answer:

∠AOC  = 50°

B is correct.

Step-by-step explanation:

In the given figure of protractor measure the ∠AOC

Please find the attachment of protractor.

OA is horizontal line which is base of protractor.

In angle AOC, two legs OA and OC

OA is base of protractor. OC another leg.

Now we see position of leg OC of angle AOC.

∠AOC  is acute angle. So, see the number bottom of protractor.

Hence, the measure of ∠AOC  is 50°
