To find Matt's typing rate, divide (4/5 page) by (2/5 hour).

Note that since both denominators are 5, we can drop the denominators. Then, Matt's rate is 4 pages divided by 2 hours, or 2 pages/hour. That's his typing rate.

Is AD parallel to BC?

Kamila [148]

For AD to be parallel 2x+4º should be equal to 79º
2(37)+4 = 78º

78º<79º

Since they aren't equal the lines are not parallel to each other.

Help please ASAP!!

Fittoniya [83]

Answer:

$\displaystyle 702$

Step-by-step explanation:

we are given a exponential function

$\displaystyle f(x) = {3}^{x + 1} - 22$

where x represents the number and f(x) represents the amount

we are also given that when x is 3 then f(x) is 59 likewise when x is 6 then f(x) is 2165

to figure out the average rate of change between 3 and 6 we can consider the average rate of change formula given by

$\displaystyle m = \frac{ f(x)_ {2} - f(x)_{1} }{ x_{2} - x_{1} }$

substitute what we have:

$\displaystyle m = \frac{ 2165 - 59 }{6 - 3 }$

simplify substitution:

$\displaystyle m = \frac{2106 }{3 }$

simplify division:

$\displaystyle m = 702$

hence, the average rate of change between 3 and 6 is 702

X1 + x2 / 2 , y1 + y2 / 2

8 + x2 /2 = 6

So x is 4

9 + y2 /2 = 6

So y is 3.

Answer is B ( 4, 3)

10x - 3(4x + 1)

seraphim [82]

Answer:

See below for answers and explanations

Step-by-step explanation:

Part A

10x - 12x - 3 does not equal -5x. Looks like what she did wrong was treating -3 as -3x and got her incorrect result that way

Part B

10x - 12x - 3 = (10-12)x - 3 = -2x - 3
