Lets work backwards, he had $5 after it all, and spent $1.25 on a snack, so we add that to the remainder, which is $6.25. then he spent half of that on whatever stuff he likes, so add $6.25 and $6.25, which is $12.50

Answer:

$12.50

Step-by-step explanation:

We have to find value of his allowance

Let Ricardo received allowance =x

He spent his allowance on anew paperback book=\frac{x}{2}

He spent money on snacks=$1.25

He had money left=$5.00

According to question

\frac{x}{2}+1.25+5=x

6.25=x-\frac{x}{2}

6.25=\frac{2x-x}{2}

\frac{x}{2}=6.25

x=6.25\times 2

x=12.50

Hence, Ricardo received his allowance for the week =$12.50

The y-intercept in the linear equation y=−110x−2 is _[blank]_.
suter [353]

Answer:

-2

Step-by-step explanation:

This linear equation is in slope-intercept format, aka y=mx+b. This is where m=slope and b=y-intercept. In the following equation, -110 is the slope and -2 replaces b, meaning it is the y-intercept

use the definition of countinuity to find the value of k so that the function is continuous for all real numbers
liubo4ka [24]

First of all, recall the definition of absolute value:

|x| = \begin{cases}x&\text{if }x\ge0\\-x&\text{if }x

So if <em>x</em> < 4, then <em>x</em> - 4 < 0, so |<em>x</em> - 4| = -(<em>x</em> - 4), and the first case in <em>h(x)</em> reduces to

\dfrac{|x-4|}{x-4}=\dfrac{-(x-4)}{x-4} = -1

Next, in order for <em>h(x)</em> to be continuous at <em>x</em> = 4, the limits from either side of <em>x</em> = 4 must be equal and have the same value as <em>h(x)</em> at <em>x</em> = 4. From the given definition of <em>h(x)</em>, we have

h(4) = 5k-4\cdot4 = 5k-16

Compute the one-sided limits:

• From the left:

\displaystyle \lim_{x\to4^-}h(x) = \lim_{x\to4}\frac{|x-4|}{x-4} = \lim_{x\to4}(-1) = -1

• From the right:

\displaystyle \lim_{x\to4^+}h(x) = \lim_{x\to4}(5k-4x) = 5k-16

If the limits are to be equal, then

-1 = 5<em>k</em> - 16

Solve for <em>k</em> :

-1 = 5<em>k</em> - 16

15 = 5<em>k</em>

<em>k</em> = 3

A line contains the points (-9,-7) and (13,-19). Find the x-value of the x-intercept.
Karolina [17]

Answer:

x = -21.83 or (-21.83, 0)

Step-by-step explanation:

Use the given points to find the slope of the line.

m=\frac{y2 - y1}{x2 - x1}

(-9, -7) (13, -19)

m=\frac{-19-(-7)}{13 - (-9)} = \frac{-12}{22} = -\frac{6}{11}

Use the slope and one of the given points to solve the point-slope formula

y - y=m(x-x)

y-(-7)=-\frac{6}{11} (x-(-9))

y+7=-\frac{6}{11} x-\frac{54}{11}

y=-\frac{6}{11} x-\frac{131}{11}

Since you are looking for the x-intercept, set y=0 and solve for x

0=-\frac{6}{11}x - \frac{131}{11}

\frac{131}{11} =-\frac{6}{11} x

-21.83 = x
