Can someone please do this for me?

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.

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

If Lisa paid $175.98 for 2 pair of shoes and 3 pair of jeans. Each pair of shoes cost 24.99. If each pair of jeans cost the same amount, then each pair of jeans cost is $42.

Two or more expressions with an Equal sign is called as Equation.

Given,

Lisa paid $175.98 for 2 pair of shoes and 3 pair of jeans

Each pair of shoes cost 24.99.

Each pair of jeans cost the same amount, we need to find how much did each pair of jeans cost.

As their are two pair of jeans

24.99+24.99=49.988

49.988 is the cost of pair of shoes.

Now let us remove 49.988 from $175.98 to find cost of jeans

175.988-49.988

125.992

$125.992 is the cost of three jeans

Now divide this by three to get cost of each jeans

125.992 which means 126, divide 126 by 3.

126/3=42

Hence, Each pair of jeans cost is $42

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

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

Answer:

One spool of thread is $2.98

Step-by-step explanation:

Answer:

$ 2.98

Step-by-step explanation:

Total amount spent by Mila equals $50.86

She bought 5 yards of fabric at $8.98 per yard. Hence, the total amount she spent on fabric is 8.98 × 5 = $44.9

It should be noted that since she bought only 2 kinds of things, this mean that Amount spent of fabric + Amount spent on thread = $50.86

Amount spent on thread = $50.86 - Amount spent on fabrics.

Amount spent on thread = $50.86 - $44.9 = $5.96

This is the total amount spent on thread.

But the question asks amount spent on one spool of thread. Since 2 spools would cost $5.96, one spool would cost $5.96 ÷ 2 = $2.98

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:

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.
