Answer:

First let's work out the lengths of each side using the equation

(y2-y1)²+(x2-x1)² and then find the square root of your answer

We get BC as root of 26

AB as root of 113

AC as root of 85

To get the perimeter of the triangle add up the values

root of 85+root of 113+root of 26=24.95 (use the unit specified)

I know the answer is a bit rushed but if you do have any questions let me know

Given f(x) = 3x - 1 and g(x)= -x + 6, find f(-2) + g(5).<br> A. -6<br> B. 6<br> C. 8

marta [7]

Answer:

A. -6

Step-by-step explanation:

$f(x)=3x-1\\\\$

In order to find $f(-2)$ we will plugin $x=-2$

$f(-2) = 3(-2)-1\\f(-2)=(3\times(-2))-1\\f(-2)=-6-1$

$f(-2)=-7$

$g(x)=-x+6$

In order to find $g(5)$ we will plugin $x=5$

$g(5)=-5+6$

$g(5)=1$

$f(-2)+g(5)\\=-7+1\\=-6$

∴ $f(-2)+g(5)=-6$

Kinda need some help

aksik [14]

Answer:

1) x=10

2) x=6

3) x=13

Step-by-step explanation:

1) 15x-17+4x+7=180

19x-10=180

19x=190

x=10

2) 13x+5=16x-13

5+13=16x-13x

18=3x

x=6

3) 9x+7=11x-19

7+19=11x-9x

26=2x

x=13

A cleaning product sells for $0.75 a quart. Which equation can be used to solve for the total cost, C , of five gallons of the p

ozzi

Answer: b. C = 5 × ($0.75 × 4)

Step-by-step explanation:

Note that 4 quarts = 1 gallon

Therefore, if a cleaning product sells for $0.75 a quart, the equation can be used to solve for the total cost, C , of five gallons of the product will be:

= 5 × ($0.75 × 4)

= 5 × $3

= $15

s the number of points scored during a basketball gamenumber of points scored during a basketball game a discrete random variab

Temka [501]

Answer:

The answer is Discrete Random Variable

Step-by-step explanation:

A random variable is considered discrete if its possible values are countable.

In our case,

In a basketball game, for example, it is only possible for a team's score to be a whole number—no fractions or decimals are allowed, and so the score is discrete.

A good rule of thumb is this: if the variable you're measuring has to be rounded before it's written down, then it's continuous. If no rounding is necessary, as with anything that's countable, then it's discrete.
