. Anna was thinking of a number. She told Bill that if he squared her number followed by subtracting 11 times her, and adding 4,

Snowcat [4.5K]

Answer:

Anna's number could be 5 and it could be 6.

Step-by-step explanation:

Let Anna's number be represented by x.

If Bill squared her number followed by subtracting 11 times her number, and adding 4, then he would get -26.

This implies that:

$x^2 - 11x + 4 = -26$

This is a quadratic equation and we can solve for x by factorization.

$x^2 - 11x + 4 = -26\\\\=> x^2 - 11x + 4 + 26 = 0\\\\x^2 - 11x + 30 = 0\\\\x^2 -6x-5x + 30 = 0\\\\x(x - 6) - 5(x - 6) = 0\\\\(x - 5) (x - 6) = 0\\\\$

=> x = 5 and x = 6

Anna's number could be 5 and it could be 6.

Rachel has been given $1000 to put into a savings account. She earns 2% simple interest

tangare [24]

Answer:

She will not have enough. She will only have $1480.

Step-by-step explanation:

The formula for simple interest is A=P(1+rt)

A=final amount

P=initial amount

r=interest rate per month

t=time in months

A=1000(1+(0.02)(24))=1480

Rachel will not have enough money after two years (24 months.)

Hope that helps!

Given segment AB with points (-4, 8) and (6, 3) respectively. Find the coordinates of point P that partitions Segment AB in the

netineya [11]

Answer:

$P = (2,5)$

Step-by-step explanation:

Given

$A(-4,8)$

$B(6,3)$

$m:n = 3 : 2$

Required

Determine P

Since P divides the segment into 3:2, P is calculated using

$P = (\frac{nx_1 +m x_2}{m+n},\frac{ny_1 + my_2}{m+n})$

Where

$(x_1,y_1) = (-4,8)$

$(x_2,y_2) = (6,3)$

$m:n = 3 : 2$

Substitute these values in the above formula:

$P = (\frac{2 * -4 +3 * 6}{3 + 2},\frac{2 * 8 + 3 * 3}{3 + 2})$

$P = (\frac{-8 +18}{3 + 2},\frac{16 + 9}{3 + 2})$

$P = (\frac{10}{5},\frac{25}{5})$

$P = (2,5)$

One number is 44 times a first number. a third number is 100 more than the first number. if the sum of the three numbers is 5385

svlad2 [7]

I take it that the actual total is 538. If it really is 538538 leave me a note.

Let the first number = x

Let the second # = 44x

Let the third # = 100x

Equation

x + 44x + 100x = 538 Add the left side. All terms are part of the total.

145x = 538 Div By 145

x = 538/145

x = 3.71

Check

First number = 3.71

Second # = 44*3.71 = 163.24

Third number = 100*3.71 = 371

Total these 3 numbers 537.95 The very tiny difference is due to rounding.
