7. f(x) = 2x + 5 What is the value of x if f(x) = 25 ?
Answer:
x=10
Step-by-step explanation:
set the 2 equations equal to each other
25=2x+5 -> subtract 5
20=2x -> divide by 2
10=x ->answer!
Hope that helps!
Answer:
x = 10
Step-by-step explanation:
f(x) equals both 25 and 2x + 5, so set the equations equal to one another and solve for x.
2x + 5 = 25
2x = 20
x = 10
Plug in what you got for x to check if it is right
2(10) + 5 = 25
20 + 5 = 25
25 = 25
Find the real-number root.
√-3.24
Answer:
1.8
Step-by-step explanation:
So, we can say that the square root of 3.24 is 1.8 with an error smaller than 0.001 (in fact the error is 0.0000276241). this means that the first 4 decimal places are correct. Just to compare, the returned value by using the javascript function 'Math. sqrt(3.24)' is 1.8
Here is a shape ABCD.
Calculate the perimeter of the shape.
Give your answer correct to 3
significant figures.

9 cm
O
9 cm
140°
21 cm
24°
А
The shape is made from a triangle and a
sector of a circle, centre O and radius 9 cm.
AD = 21 cm
Angle AOD = 140°
Angle OAD = 24°
Total marks: 5
9514 1404 393
Answer:
59.8 cm
Step-by-step explanation:
The length of arc ABC is ...
s = rθ
s = (9 cm)(220/180π) = 11π cm ≈ 34.558 cm
The length of segment CD is 9 cm less than the length of segment OD. OD can be found using the law of sines.
OD/sin(A) = AD/sin(O)
OD = AD·sin(A)/sin(O) = (21 cm)sin(24°)/sin(140°) ≈ 13.288 cm
Then the length of CD is ...
CD = OD -9 cm = (13.288 cm) -(9 cm) = 4.288 cm
The perimeter is the sum of the segment and arc lengths:
P = ABC + CD +AD
P = 34.558 cm + 4.288 cm + 21 cm = 59.846 cm
The perimeter of the shape is about 59.8 cm.

You spin the spinner and flip a coin. Find the probability of the compound event.
The probability of spinning a prime number and not flipping heads is...
Answer:
3/10 or 0.3
Step-by-step explanation:
The numbers in the spinners are given to be:
{1,2,3,4,5}
Total number of outcomes are: 5
On spinning the spinner, the outcomes which are prime are:
{2,3,5}
Hence, the probability that a prime number is obtained is:
3/5
Also, the probability that a head is not obtained i.e. a tail is obtained is:
1/2
Hence, the compound probability of spinning a prime number and not flipping head is:
3/10 or 0.3

Wo groups are hiking at about the same speed. Mario's group hikes for 2.5 hours. Seema's group hikes for 4.7 hours and covers 8.8 more miles. How fast are the hikers going? Solve the equation below to find out. 4.7x = 2.5x + 8.8
Answer:
x = 4 miles per hour
Step-by-step explanation:
4.7x = 2.5x + 8.8
Collecting like terms
4.7x - 2.5x = 8.8
2.2x = 8.8
x = 8.8 / 2.2
x = 4 miles per hour
