Answer:

John had $2088 originally in his savings accounts.

Step-by-step explanation:

Let John had $x originally in his saving account

He spent $198 on a radio. The remaining money = x - $198

4/12 of what was left, he spent on presents for his friends. Remainig money = x - 198 - 4/12*(x-198)

= (1 - 4/12) of (x-198)

= 2/3 of (x-198)

John then put 2/9 if his remaining money into a checking account.

Now, the remaining money = 2/3*(x-198) - 2/9 of (x-198)

= (1 - 2/9) * 2/3*(x-198)

= 7/9 * 2/3*(x-198)

= 14/27(x-198)

Money left with him = $980

14/27(x-198) = $980

x - 198 = $980 * 27 / 14

x - 198 = 1890

x = 1890 + 198

x = 2088

Hence, John had $2088 originally in his savings accounts.

Step-by-step explanation:

The required value of x is 3 for the given trapezoid.

A trapezoid is a quadrilateral having two parallel bases and one set of other sides called as legs.

Given that EF and HG are the bases and J and K are the midpoints of the legs, we can use the midsegment theorem which states that:

The segment connecting the midpoints of the legs of a trapezoid is parallel to the bases and is equal to half the length of the bases.

We can use this theorem to write the equation:

JK = (EF+HG)/2

Now we are given that:

EF=3x+2 , HG=7x−2 , and JK=15

So we can substitute these values in the equation:

15 = (3x+2+7x-2)/2

15 = (10x)/2

15 = 5x

x = 3

Thus, the required value of x is 3.

Answer:

+9.4 to the nearest tenth

Step-by-step explanation:

(-4, 5) (4, 0)

Refering to the x-coordinates and the y-coordinates of these two points, we see that x changes from -4 to 4, a change of 8, which forms the horizontal leg of a right triangle.  Simultaneously, y changes from 5 to 0, a change of 5, which forms the vertical leg.  Now use the Pythagorean Theorem to determine the length of the hypotenuse of this triangle; this hypotenuse is the distance between the two points:

distance = +sqrt(8^2 + 5^2) = +sqrt(64 + 25) = + sqrt( 89) = +9.43 to the nearest hundredth and +9.4 to the nearest tenth.

Answer:

x= 14

y=5

Step-by-step explanation:

AOC and BOD are vertical angles so they are equal

AOC = BOD = 25

MOD = 90

MOD = MOB+ BOD

90 = 3x+23  + 25

Combine like terms

90 = 3x +48

Subtract 48 from each side

90-48 = 3x

42 = 3x

Divide by 3

42/3 = 3x/3

14 =x

We know that 5y+ 3x +23+90 = 180 since AB is a straight line

5y+ 3x +113 = 180

subtract 113 from each side

5y+3x =67

5y+ 3*14 =67

5y +42 = 67

5y = 67-42

5y = 25

Divide by 5

y = 25/5

y =5

Answer:

$3,955

Step-by-step explanation:

Given that:

Initial deposit = $3500

Simple rate of interest = $3.25%

Number of years = 4

Simple interest = (principal * rate * time)

Principal = Initial deposit = $3500

Interest = $3500 * 3.25% * 4

Simple Interest = $455

Amount that will be in account after 4 years :

$3500 + $455 =$3955

Answer: A) True because the leading coefficient is negative

Explanation:

The leading term is -x^2 since this term has the largest exponent.

The leading coefficient is -1 as it's the coefficient of the leading term.

It might help to write -x^2 as -1x^2

The negative leading coefficient makes the parabola open downward, so each endpoint goes off to negative infinity. The graph looks like a frowny face. You can think of a negative emotion going with a frowny face, so that negative emotion matches with the negative leading coefficient. There are probably other ways to remember but that's the trick I use.

The error is he set the factored expressions equal to each other(option3).

In a graph, the point where the line or curve crosses the axis is called the intercept. If a point crosses the x-axis it is x-intercepts. If a point crosses y-axis it is y-intercepts.

For finding x-intercepts of the given function,

First we have to factorize the given equation and then find the x values .

In [tex]f(x)=x^{2} +4x+3[/tex]

When we factorize we get , (x+3) and (x+1)

i.e., x+3=0⇒x=-3, x+1=0⇒x=-1.

That is x- intercept is -1 and -3.

Instead of this step Mathieu equated x+3=x+1.

This makes an error.

Hence, the error is he set the factored expressions equal to each other.

Step-by-step explanation:

Answer:

27

Step-by-step explanation:

(5+√2)²

you distribute the ² in the ()

so 5²+√2²

5²=25

√2²=2 because the √ and ² cancel each other out and you get 2

so now you have

25+2

which equals

27

Given expression:

             (5 + [tex]\sqrt{2}[/tex])²

Now let us solve this problem by simplifying it;

    (5 + [tex]\sqrt{2}[/tex])²:

   the power implies the expression in the bracket should be repeated twice:

        = (5 + [tex]\sqrt{2}[/tex])  (5 + [tex]\sqrt{2}[/tex])

  Then expand the bracket by distribution;

     =  (5 x 5) + 5([tex]\sqrt{2}[/tex]) + 5([tex]\sqrt{2}[/tex]) + 2

     = 25 + 10[tex]\sqrt{2}[/tex] + 2

     =  27 + 10[tex]\sqrt{2}[/tex]
