Determine whether the two triangles are congruent or not

Answer:

B, or -75

Step-by-step explanation:

f(x) is a function of x.

If f(x) = 50 when x = -10, you can rearrange this information.

f(-10) = 50

f = -5

If f = -5...

-5 ( 15) = -75

Answer:

9

Step-by-step explanation:

no, I don't think so because 6/2=3 and in the bracket 1+2=3 and if we multiple them then the answer should be 9 (3×3=9)

Answer:

[tex]m=\frac{5}{2}[/tex]  

If I am wrong its   [tex]m=\frac{-5}{-2}[/tex]

Step-by-step explanation:

Finding the slope of [tex](-4,5)(-8,-5)[/tex] we use the slope formula

[tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

[tex]m=\frac{5}{2}[/tex]

Simplify the answer if needed

[tex]m=\frac{-10}{-4} =\frac{5}{2} =2.5[/tex]

C opens up with a vertex at (-4,-1)

Answer:

A

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

y = (x - 4)² - 1 ← is in vertex form

with vertex = (h, k ) = (4, - 1 )

• If a > 0 then the graph opens up

• If a < 0 then the graph opens down

Here a = 1 > 0 then graph opens up

Thus option A

Answer:

  46.8

Step-by-step explanation:

The missing angle in ∆PQR is 180° -76° -41° = 63°. Two angles are the same between the triangles, so we know they are similar. Side lengths of similar triangles are proportional.

Corresponding sides of the triangles are ...

  ST ⇔ PQ   ratio ST/PQ = 16.8/14 = 1.2

  TU ⇔ QR   ratio TU/QR = x/10 = 1.2 ⇔ x = 12

  US ⇔ RP   ratio US/RP = 18/15 = 1.2

The perimeter of ∆STU is the sum of its side lengths ...

  16.8 +12 +18 = 46.8 . . . units

_____

Additional comment

The perimeter of PQR is 14 +10 +15 = 39. The scale factor applies to the perimeter, just as it does to the side lengths.

The perimeter of STU is 1.2×39 = 46.8.

Answer:A

Step-by-step explanation:11m3-

Answer:

The short answer is there isn’t.

Start by writing each of these as an expression:

x * y = 60

x + y = 7

Next, solve each for the same variable; in this case, y:

(x * y) / x = 60 / x

.: y = 60 / x

(x + y) - x = 7 - x

.: y = 7 - x

Next, replace y of the second expression to the first

y = 60 / x & y = 7 - x

.: 7 - x = 60 / x

Now, solve for x:

(7 - x) * x = (60 / x) * x

.: x * 7 - x^2 = 60

This is quadratic, so write it in the form of ax2 + bx + x = 0

(-1)x^2 + (7)x + (-60) = 0

.: a = -1, b = 7, c = -60

Finally solve for b:

x = (-b +- sqrt(b^2 - 4*a*c)) / 2a

.: x = (-7 +- sqrt(7^2 - 4*-1*-60)) / (2 * -1)

.: x = (-7 +- sqrt(49 - 240)) / -2

.: x = (-7 +- sqrt(-191)) / -2

The square root of a negative value is imaginary and thus there’s no real answer to this problem.

Answer:

x=9

Step-by-step explanation:

a scale drawing means all the sides are multiplied by the same amount. to find this amount, you can divide the larger side by the bigger side by the smaller side.

15/5 = 3

12/4 = 3

therefore the scale factor is 3. to get the value of x, multiply the value of the third side by 3.

3*3=9

x=9

Answer:994

Step-by-step explanation:

(8+2) first because of pemdas.

now do 10^3 which =1000

And now subtract 6 from it.

1000-6=994

Answer:

its 84 dollars sorry I'm late

Step-by-step explanation: Make a proportional relationship.

make 120% into a fraction. 120/100

then make 70 into a fraction using a variable. For example, x/70

Then cross multiply 120 and 70. 120x70=8,400

Last divide 8,400 by 100 and that equals $84.

Factors are 9x-6 and 9x+6

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

Explanation:

We use the difference of squares rule

m^2 - n^2 = (m-n)(m+n)

In this case we have

So,

m^2 - n^2 = (m-n)(m+n)

(9x)^2 - 6^2 = (9x-6)(9x+6)

81x^2 - 36 = (9x-6)(9x+6)

Answer:

9x + 6 and 9x -- 6

Step-by-step explanation:

81x2--36 = (9x) 2 -- (6)2 = a2 -- b2 = (a+ b )(a--b) = (9x+6)(9x-6)

Step-by-step explanation:

Vertical length of the smaller  triangle is:

Horizontal length of the smaller triangle is:

The fraction:

This fraction is same for the larger triangle, which is 4/6 = 2/3.

It means the slopes are same.

Since the slopes are same, the segments are part of same red line.

Answer:

I cannot answer that but here is an example problem to help.

Step-by-step explanation:

11.92 × 3.21 = 38.2632

Answer:

-If you need to round to the whole number, you would round down to 38

-If your answer needs to be a decimal, it would be 38.30

If you don't have a specific way you need to round it, estimates are usually whole numbers, so your answer would be 38
