Answer:

PR= 8

ST=5

Step-by-step explanation:

PQ and PR are congruent so

2x=8

x=4

2*4=8

PR=8

ST and TU are congruent so

5z=2z+3

3z=3

z=1

5*1=5

ST=5

Answer:

PR=8

ST=5

Step-by-step explanation:

PR

QS=SR (marked)

a²=b²+c² (TRIANGLE PQS)

PQ²=PS²+QS²

8²=PS²+SR² (PQ=8, QS=SR)

64=PS²+SR²

a²=b²+c² (TRIANGLE PRS)

PR²=PS²+SR²

(2x)²=64

2x=8

x=4

PR=2x=2(4)=8

ST

a²=b²+c² (TRIANGLE VUT)

VT²=TU²+UV²

VT²=(2z+3)²+UV²

VT²=4z²+12z+9+UV²

a²=b²+c² (TRIANGLE VST)

VT²=VS²+ST²

VT²=VS²+25z²

4z²+12z+9+UV²=VS²+25z²

21z²-12z-9=0

7z²-4-3=0

(7z+3)(z-1)=0

z=-3/7 or z=1

cant be neg, z=1

ST=5(1)=5

Answer: x-1/8y^2=0

Answer:

Step-by-step explanation:

You are given the equation for the number of times, y, that she visits them by distance x. You need only substitute the given x=4 into the equation y(x)

y=-3.5x+20, using x=4

y=-3.5(4)+20

y=-14+20

y=6

So we would expect her to visit her friend four miles away six times a month.

for blank 1 the answer is "slope" and for blank 2 the answer is y-intercept (slope intercept form is y=mx+b, m=slope and b=y-intercept).

Answer:

B

Step-by-step explanation:

I think the answer is B because the expression shows 3 times x (Representing the number),  and the diagram shows 3 xs.  I was very confused about the first diagram but I still think it's B.  Sorry if I'm wrong.  

Answer:

$0.25 per inch

Step-by-step explanation:

1 yard = 36 inches

Answer:

It is 68

Step-by-step explanation:

[tex]2x - 10 = x + 6 \\ 2x - x = 6 + 10 \\ x = 16[/tex]

[tex]let \: (y) \: the \: angle \: which \: wanted \\ 90 = y + (2x - 10) \\ 90 = y + (32 - 10) \\ y = 90 - 22 \\ y = 68[/tex]

Thanks alot

The set of numbers that have 11 as a common factor is {154, 231}.

The number that divides two or more numbers is called a common factor.

Given are the pair of numbers as -

{154, 231}

{143, 221}

{33, 39}

{77, 91}

The pair of numbers with the common factor 11 is {154, 231}.

Answer:

1 2/3

Step-by-step explanation:

If you make all of their denominators 15, you would get 12/15 + 10/15 + 3/15, which is equal to 25/15, which is 1 10/15. 10/15 simplifies to 2/3, so the answer is 1 2/3.

7(4/5 + 2/3) + 1/5 = Help?

Answer:

B. f(x) = -2x - 5

Step-by-step explanation:

✔️Find the rate of change:

Rate of change using two of the given pair, say (0, -5) and (1, -7)

Rate of change (m) = ∆f(x) / ∆x = (-7 -(-5)) / (1 - 0) = -2/1 = -2

✔️Find y-intercept (b):

y-intercept (b) = -5 because the y-intercept is the value of f(x) when x = 0.

✔️Substitute m = -2 and b = -5 into f(x) = mx + b

Thus,

f(x) = -2x + (-5)

f(x) = -2x - 5
