Answer:

3 3/4

Step-by-step explanation:

8 3/4 beads dozen beads, uses 3 1/4 beads for necklace, 1 3/4 beads for necklace so she has used 3 1/4 + 1 3/4 beads which is 5 so 8 3/4 - 5 = 3 3/4

Alborosie

Answer:

Part A: (2x−5)(x+2)

Part B: (5/2,0) and (-2,0)

Part C: The graph of f(x) has both "ends" of the graph pointing upward. You can describe this as heading toward infinity.

Part D: To graph function we can use x-intercepts and "ends" to sketch.In order to graph better use one more point of parabola that you can find as the average of x-intercepts: (-2+5/2)/2 =1/4.This is just x coordinate and you need to plug in 1/4 in the f(x) and find y coordinate -10 1/8. You can use y-intercept (0,-10) as well to graph.

Step-by-step explanation:

2x^2-3x-5=y

(2x-5)(x+1)=y

(2x-5)(x+1)=0

2x-5=0

2x=5

x=2.5

x+1=0

x=-1

you have an even degree (2) and a positive coefficient (2)

therefore as x---> -∞, f(x)----> +∞

also, as x----> +∞, f(x)----> +∞

also notice that this is a parabola that opens upwards so both "ends" approach positive infinity

plot the x-intercepts, find the vertex using h=-b/2a and substituting this value into the equation to find k and make a table of values to graph the parabola unless you only want a rough sketch of the graph-you know the x-intercepts and you found the vertex using h=-b/2a

Can someone help<br> Me please

Kay [80]

Answer: -6. 4. -3,75. 37.

Step-by-step explanation: -20|+10-2²= -6, since a minus×minus give you a + therefore -2²=4.

2³+(-8)= 12-8=4, a minus×plus gives you a minus.

-2,50+(-1,25)=-2,50-1,25=-3,75. |-10|+|20|-5²-(-2)=-10+20+25+2=37.

jenny charges $9.15 an hour to babysit toddlers and $7.45 an hour to babysit school-aged children, if jenny babysat toddlers for

choli [55]

The total money earned by Jenny is $\boxed{\bf \$\ 127.05}$ .

Further explanation

Multiplication is a arithmetic operation such that two real numbers are performed in such a way that they derive a third number called product.

Procedure used:

The following steps are involved to find the value of $y\text{ unit}$ where $y$ is any real number.

1) If one unit is equal to $x$ then multiply $y$ with $x$ .

2) The resultant number would be $xy$ is the value of $y\text{ unit}$ .

Given:

Jenny charges $\$\ 9.15$ an hour to babysit toddlers and $\$\ 7.45$ an hour to babysit school-aged children. She babysat toddlers for $9\text{ hours}$ and school aged children for $6\text{ hours}$ .

Calculation:

Step 1: Jenny earns through babysit toddlers.

If jenny charges $\$\ 9.15$ an hour to babysit toddlers and she does this job for $9\text{ hours}$ .

The earning money from babysit toddlers using above procedure can be calculated as follows:

$\begin{aligned}a&=9.15\cdot 9\\&=82.35\end{aligned}$

Therefore, jenny earns $\$\ 82.35$ by babysit toddlers.

Step 2: Jenny earns through school aged children.

If jenny charges $\$\ 7.45$ an hour to babysit school aged children and she does this job for $6\text{ hours}$ .

The earning money from babysit school aged children using above procedure can be calculated as follows:

$\begin{aligned}b&=7.45\cdot 6\\&=44.7\end{aligned}$

Therefore, Jenny earns $\$\ 44.7$ by babysit school aged children.

Step 3: Total amount earn by Jenny.

The total earning is the sum of earning through babysit toddlers and babysit school aged children.

The total earning is calculated as follows:

$\begin{aligned}\text{Total money}&=82.35+44.7\\&=127.05\end{aligned}$

Thus, total money earned by jenny is $\boxed{\bf \$\ 127.05}$ .
