Maryland had $(62xsquared + x - 4) on mondays she spent $(11x squared - 33) on a pair of gloves how much money did she have left

Anton [14]

Answer:

$( 51x^2 + x + 29).

Step-by-step explanation:

Amount she had left = original amount - amount spent on the gloves

= 62x^2 + x - 4 - (11x^2 - 33) (note we place the amount spent on gloves in parentheses because we have to subtract the whole amount)

Now we distribute the negative over the parentheses:

= 62x^2 + x - 4 - 11x^2 + 33 ( note - 33 becomes -33*-1 = +33)

Now simplifying like terms:

= 51x^2 + x + 29 (answer).

Find an equation of the line perpendicular to y=4x+5 and that passes through the point (0,-1)

iragen [17]

Answer:

y = -1/4x - 1.

Step-by-step explanation:

y = 4x + 5

The slope of this is 4 so the slope of line perpendicular to this line = -1/4.

Using the formula y - y1 = m(x - x1):

y - (-1) = -1/4(x - 0)

y + 1 = -1/4x

y = -1/4x - 1.

Given B is between A and C, find the value of x if AB = 27, BC = 11x, and AC = 159

True [87]

Answer:

Step-by-step explanation:

Since, B is between A and C.

$\therefore AB + BC=AC \\ 27 + 11x = 159 \\ 11x = 159 - 27 \\ 11x = 132 \\ x = \frac{132}{11} \\ x = 12$
