Answer:

c

Step-by-step explanation:

The third function has a range of y that is greater than or equal to 0.

A function is a kind of rule that, for one input, gives you one output.

For the first function, it contains negative values for y, so it was eliminated.

The second function did not start from zero, so it was eliminated.

The third function obeys the given condition, but the last function contains negative values for y.

Hence, the third function satisfies the condition that y is greater than or equal to 0.

the given angle of 1 is 100

The measure of ∠1 is equivalent to 100°.

Given is that pentagon ABCDE ≈ pentagon FGHIJ.

Since the pentagons are similar, we can say that the corresponding angles will be equal. So, we can write -

∠1 = 100°

Therefore, the measure of ∠1 is equivalent to 100°.

Answer:

Fatima's points = 46

Zahra's points = 30

Step-by-step explanation:

Let's give names to the unknowns (the number of points each one got)

Fatima's points = y

Zahra's points = x

Now create the equations given by the info they provide:

"Fatima got 16 marks more than Zahra"

y = x + 16

"The product of their mark is 1380."

x * y = 1380

Now use the first equation as substitution for "y" in the second equation:

x * (x + 16) = 1380

reduce the expression:

x^2 + 16 x = 1380

x^2 + 16 x - 1380= 0

Solve using quadratic formula:

[tex]x=\frac{-16+/- \sqrt{16^2+4(1380)} }{2} \\x=\frac{-16+/- \sqrt{5776} }{2} \\x=-8+/- 38\\x = 30\,\,\,or\,\,\,x=-46[/tex]

we pick 30 since the scores from a test must be larger than zero.

Now we use the first equation to solve for the other variable;

y = 30 + 16 = 46

then x = 30 and y = 46

Answer:

44

Step-by-step explanation:

30 - 3x2÷3 + 8x2

= 30 - 6÷3 + 16

= 30 - 2 + 16

= 28 + 16 = 44

Answer:

$7.50

Step-by-step explanation:

You can use proportions to find that 8/10 = 6/x

then you can multiply 10 by 6 and divide the result by 8 to get the answer.

You can also divide 10 by 8 to get 1.25 and multiply it by 6, as 10 divided by 8 gives you the unit rate, or the price of each battery. Then you multiply it by 6 to get 7.5, or the cost of 6 batteries.

Hope this helps!

Answer:

3x+7=10x-22

We simplify the equation to the form, which is simple to understand

3x+7=10x-22

We move all terms containing x to the left and all other terms to the right.

+3x-10x=-22-7

We simplify left and right side of the equation.

-7x=-29

We divide both sides of the equation by -7 to get x.

x=4.14285714286

Answer:

(-13,-1)

Step-by-step explanation:

Moving right means moving positively on the x-axis

Moving left means moving negatively on the x-axis

Follow the equation backwards using the x-coordinate:

Move left 10 units-- -5-10 = -15

Move right 2 units-- -15+2 = -13

Since the y-coordinate did not change, the point you started at is (-13,-1)

Let a be the amount of 40% solution and b be the amount of pure alcohol that you will use.

You want to end up with a volume of 660 mL, so

a + b = 660

For each mL of solution used, the 40% solution would contribute 0.4 mL of alcohol, and the pure alcohol will contribute 1 mL of alcohol. In the desired solution, you want a concentration of 80% alcohol, so that it contains 0.8 • 660 mL = 528 mL of alcohol, and

0.4a + b = 528

Solve the system of equations above. Subtracting the second from the first eliminates b and lets us solve for a :

(a + b) - (0.4a + b) = 660 - 528

0.6a = 132

a = 220

Then

220 + b = 660

b = 440

So you will need 220 mL of the 40% solution and 440 mL of pure alcohol.

Answer:

She buys 20 Stamps of $0.15 and 40 Stamps of $0.35.

Step-by-step explanation:

40 x 0.35 = 14

20 x 0.15 = 3

$14 + $3 = $17

40 ($0.35) + 20 (0.15) = 60 stamps

Answer:

13

Step-by-step explanation:

AB = 20

DE =12

Since AB and DE bisect each other, therefore:

AC = CB = ½(AB)

AC = CB = ½(20)

AC = CB = 10

Also,

DC = CE = ½(DE)

DC = CE = ½(12)

DC = CE = 6

Since F is the midpoint of DC, therefore:

FC = ½(DC)

FC = ½(6)

FC = 3

Find the value of FC + CB. Plug in the values of FC and CB:

3 + 10 = 13

Answer:

The slope of the parallel line is 2

Step-by-step explanation:

Parallel lines have equal slopes, so for this question you need to re-format the equation to match a y=mx+b format (slope-intercept form).

2x -y = 7  |  Subtract 2x from both sides

-y = 7 + 2x  |  Multiply by negative one to make y even

y = 7 + 2x  |  Rearrange the equation to match the formula

y = 2x +7  |  2 is your slope for both parallel lines!
