Answer:

15+x=23

Step-by-step explanation:

Answer:

(-5x2)•3=

-15x^2

Answer:

Step-by-step explanation:

 x+    y+z=19   ...(1)

2x+6y+z=12   ...(2)

3x+8y+z=-14    ...(3)

(2)-(1) gives

x+5y =-7   ...(4)

(3)-(1)  gives

2x+7y= -33   ...(5)

multiply (4) by 2

2x+10y=-14   ...(6)

(6)-(5) gives

3y=19

y=19/3

x+95/3=-7

x=7+95/3=(21+95)/3=116/3

from (1)

116/3+19/3+z=19

(116+19)/3+z=19

135/3+z=19

45+z=19

z=19-45=-26

Answer:

30 field goals

Step-by-step explanation:

80 is 4/5 of 100. To find what to multiply 5 by, I will divide 24/4, since it is 4/5. 24/4 is 6, and 6*5 is 30. So, the answer is 30. To check, I know that 24 has four sixes within it, and 30 has five sixes within it. 4/5=4/5.

Step-by-step explanation:

The solution is Option B.

The total net-worth of Emily is given by the equation A = $ 87,025

An individual's net worth is the difference between their assets (both long-term and short-term) and their liabilities (long-term and short-term).

The net worth of a company is equivalent to its equity, which refers to the net assets owned by the stockholders after paying off all debts.

So , Net Worth = Assets - Liabilities

Given data ,

Let the net worth of Emily be represented as A

Now , the equation will be

The assets of Emily are = Checking account $750 + Automobile (current value) $8,950 + House (current value) $92,500 + Savings account $1,350 + Investments $4,000

The total assets of Emily = $107,550

And , the liabilities of Emily are = Credit card debt $3,800 + Student loans $15,750 + Personal loans $975 + Total Liabilities $20,525

Now , the total liabilities of Emily = $20,525

So , the net worth = Assets - Liabilities

Substituting the values in the equation , we get

Net worth of Emily A = $107,550 - $20,525

On simplifying the equation , we get

Net worth of Emily A = $ 87,025

Hence , the net worth of Emily is $ 87,025

[tex]\overline{DE} \cong \overline{GF}[/tex] and [tex]\overline{DG} \cong \overline{EF}[/tex] by CPCTC

Step-by-step explanation:

The given information are;

The shape of the given polygon DEFG = Parallelogram with diagonal DF

Therefore, we have;

Response area

[tex]\overline{DE} \left | \right | \overline{GF}[/tex] and  [tex]\overline{DG} \left | \right | \overline{EF}[/tex] (Opposite sides of a parallelogram are parallel)

∠GFD ≅ ∠EFD (Alternate interior angles)

∠DFG ≅ ∠FDE (Alternate interior angles)

[tex]\overline{DF} \cong \overline{DF}[/tex] (By the reflexive property of congruence)

Therefore

ΔDGF ≅ ΔFED (Angle-Side-Angle (ASA) condition of congruency)

Which gives;

[tex]\overline{DE} \cong \overline{GF}[/tex] and [tex]\overline{DG} \cong \overline{EF}[/tex] (Congruent Parts of Congruent Triangles are Congruent (CPCTC).

x= −29/4

Answer:

Step-by-step explanation:

−7(x+2)=−3(x−5)

Step 1: Simplify both sides of the equation.

−7(x+2)=−3(x−5)

(−7)(x)+(−7)(2)=(−3)(x)+(−3)(−5)(Distribute)

−7x+−14=−3x+15

−7x−14=−3x+15

Step 2: Add 3x to both sides.

−7x−14+3x=−3x+15+3x

−4x−14=15

Step 3: Add 14 to both sides.

−4x−14+14=15+14

−4x=29

Step 4: Divide both sides by -4.

−4x −4

x=29/−4

x= −29/4

Answer:

f(-6) = -2

Step-by-step explanation:

plug in k value (-6)

f(-6) = -6/2 + 1

theres two ways to solve for this

one way:

convert the whole number 1 to an improper fraction

f(-6) = -6/2 + 2/2

combine like terms

f(-6) = -4/2

divide -4 by 2

f(-6) = -2

second way:

divide -6 by 2

f(-6) = -3 + 1

combine like terms

f(-6) = -2

either way you get the same answer

use whichever is easiest for you

Answer:  A.

Step-by-step explanation:

Answer:

Angela is 12 and Micah is 28.

Step-by-step explanation:

So, the problem tells us that Micah is four more than twice Angel's age, and the sum of both their ages is 40. So, if we use a to stand for Angela's age and m to stand for Micah's age, we can safely assume our equation will look like this:

(a × 2) + 4 = m. And once that is figured out, we use a + m = 40.

For right now, we can start just randomly entering in numbers for a. Let's try 10, for example.

(10 × 2) + 4 = 24.

But does 10 + 24 = 40? No, it equals 34. So we go higher.

(12 × 2) + 4 = 28.

Does 12 + 28 = 40? Yes, yes it does.

So we can say with all certainty that Micah is 28 years old, and Angela is 12.

72 because 120% x 60 = 72 or 60 ÷ 100 x 120 = 72

Answer:

The fourth image, or D.

Why?

If you had a ruler and placed it on the grid vertically and moved the ruler left to right, pictures A, B, and C, all have two points that lay on the same X point.

Picture D is the only one that has no points that lay on the same X point, thus making it the right answer.

The last graph (shown below) passes the vertical line test

The vertical line test is used to ascertain whether or not a graph represent a function.

Vertical lines are drawn across the graph. If the vertical line intersects more than one point on the graph, then the graph does not represent a function.

If a vertical lines are drawn across all the graphs shown, only the last graph indicated below will pass the vertical line test.

Therefore, the graph shown below represents a function because it obeys the vertical line test

Step-by-step explanation:

3x^2-x+5.2f\left(-3\right)-f\left(4\right)

=3x^2-x-5.2f\cdot \:3-f\cdot \:4

=3x^2-x-15.6f-4f

=3x^2-x-19.6f

The required value of the given expression is 1.

An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.

The variable part of an algebraic expression can never be added or subtracted from the constant part.

The given function is as below,

f(x) = 3x² - x + 5

The value of the function at x = -3 and 4 can be found by substituting the respective values of x  in the expression of f(x) as follows,

f(-3) =  3 × (-3)² - (-3) + 5

      = 25

And, f(4) = 3 × (4)² - 4 + 5

              = 49

Then,  2f(-3) - f(4) = 2 × 25 - 49

                            = 1

Hence, the given expression can be evaluated as  2f(-3) - f(4) = 1.

Answer:

f(x) is the amount awarded to a player upon rolling the die

The domain of the function = 1, 2, 3, 4, 5, and 6

The values of the function are 5, 7, 9, 11, 13, and 15

Step-by-step explanation:

The given information includes;

The function f(x) = 2·x + 3

Given that f(x) is the amount awarded to a player upon rolling the die, and x = The value rolled on the die, we have;

The values of x are 1, 2, 3, 4, 5, and 6

The values of the function then becomes;

f(x) = 2·x + 3

{x = 1, 2, 3, 4, 5, and 6} {f(x) = 5, 7, 9, 11, 13, and 15}

Therefore, the domain of the function = 1, 2, 3, 4, 5, and 6
