Three fifths of seven

Find the value of x. 7, 8, and 9 please!

natima [27]

Answer:

7) x= 5, 8) x= 6, 9) x= 7

Step-by-step explanation:

As per the secant theoram, if two secant intersect outside the circle then the product of the exterior secant and total length of each secant are equal.

7) ∴ $(x+3)\times 3= (10+2)\times 2$

opening parethesis and distributing 3 with x and 3.

⇒ $3x+9=24$

subtracting 9 on both side.

⇒ $3x=15$

cross multiplying

∴ x= 5.

8) $(3+5)\times 5= (x+4)\times 4$

Opening parethesis and distributing 4 with x and 4.

⇒ $8\times 5=4x+16$

⇒ $40=4x+16$

subtracting 16 on both side.

⇒ $24=4x$

cross multiplying

∴ x= 6.

9) $(x+5)\times 5= (6+4)\times 6$

opening parethesis and distributing 5 with x and 5.

⇒ $5x+25=60$

subtracting 25 on both side.

⇒ $3x=35$

cross multiplying

∴ x= 7.

How do defined terms and undefined terms relate to each other?

Ksivusya [100]

UNDEFINED terms can be combined to define other terms. Noncollinear points, for example, are points that do not lie on the same line. DEFINED terms can be combined with each other and with undefined terms to define still more terms.

ANSWER CORRECTLY AND IF YOU DONT KNOW IT JUST DONT SAY ANYTHING

arlik [135]

9514 1404 393

Answer:

A. 40, dollars added per day to the bank account

B. y -600 = 40(x -0); y = 40x +600; 40x -y = -600

C. f(x) = 40x +600

D. $880

Step-by-step explanation:

A. The slope is given by the formula ...

m = (y2 -y1)/(x2 -x1)

m = (720 -600)/(3 -0) = 120/3

m = 40

The bank account is increasing at the rate of $40 per day.

__

B. Point-slope form is ...

y -k = m(x -h) . . . . . line with slope m through point (h, k)

Using the first point, we have (h, k) = (0, 600) and m = 40.

y -600 = 40(x -0)

Slope-intercept form is ...

y = mx +b . . . . . . line with slope m and y-intercept b

The first point tells us the y-intercept is b=600, so the equation is ...

y = 40x +600

Standard form is ...

ax + by = c . . . . . . . a > 0, and a, b, c mutually prime

This form can be obtained by subtracting y from the point-slope form.

40x -y = -600

__

C. Replacing y with f(x) in the slope-intercept form gets the desired equation.

f(x) = 40x +600

__

D. The table shows the balance after 6 days. The balance increases $40 each day, so the balance after 7 days is ...

$840 +40 = $880 . . . . balance after 7 days

Step-by-step explanation:

$125,000 * 0.08 = 10,000\\125,000 - 10,000 = 115,000\\115,000 * 1/2 = 57,500$

An (independent or dependent) variable can be assigned any value. The variable that changes depending on the (independent or dep

True [87]

Answer:

An independent variable can be assigned any value. The variable that changes depending on the independent variable is called the dependent variable.
If x is the independent variable, then y would be considered the dependent variable and will change depending on the value of x.

Step-by-step explanation:

The key word is "depending". The dependent variable changes depending on the independent variable.
