Answer:
f(3) = 16 and f(4) = 23
Step-by-step explanation:
Finding f(3) simply means we're finding the value of the function when x = 3, so we can plug 3 in for x in our function:
f(3) [tex]3^{2} +7[/tex]
[tex]3^2 = 9[/tex], so now we have:
f(3) = 9 + 7
9 + 7 = 16, so f(3) = 16.
Now we want to find the value of x that makes the function equal 23, so let's set our function equal to 23:
[tex]23 = x^2 + 7[/tex]
We want to get x by itself in order to find the value, so let's start by subtracting 7 from both sides:
23 - 7 = [tex]x^2[/tex]
23 - 7 = 16, so 16 = [tex]x^2[/tex]
Now, we can take the square root of both sides:
[tex]\sqrt{16} = \sqrt{x^2} \\\sqrt{16} = 4\\\sqrt{x^2} = x[/tex], so now we have:
4 = x

12) New York City is a popular field trip destination. This year the senior class at High School A and
the senior class at High School B both planned trips there. The senior class at High School A
rented and filled 4 vans and 7 buses with 448 students. High School B rented and filled 9 vans
and 14 buses with 910 students. Every van had the same number of students in it as did the
buses. Find the number of students in each van.
Answer:
the number of students in each van : 14
Step-by-step explanation:
a = how many students fit into a van
b = how many students fit into a bus
School A: 4a+7b=448 (1)
School B: 9a+14b=910 (2)
(1) => b = (448-4a)/7
subs to (2) => 9a+ 2(448-4a) = 910
=> a = 14
=> b =56

12a2
Answer:
Think the answer is 3a. Hope that helped.
Since 3a is common to both factors, hence the GCF of the expressions is 3a
Greatest common factorThis is the greatest value that can divide the given values without leaving remainder.
Given the following expressions 12a and 9a^2
Find the factors
12a = 3 * 4 * a

what method was probably used to construct the pyramids
Evidence points to the Egyptians using gypsum mortar – also known as plaster of Paris – in constructing pyramids during the Pharaonic period. The first Egyptologist to identify this method was Alfred Lucas in 1926.
solution of the equation 2x+1=x+3
a. 3
b. 1
c. 2
d. 4
Answer:
C. x = 2
Step-by-step explanation:
2x + 1 = x + 3
subtract the x from both sides so
2x + 1 = x + 3
-x -x
when we subtract the x we are left with x + 1 = 3
since we want x alone we have to subtract 1 from both sides so
x + 1 = 3
-1 -1
3 - 1 = 2 so
x = 2

What is the slope of the line?
Answer:
m = 1Step-by-step explanation:
Find the slope using two points on the line:
(0, -3) and (3, 0)Use slope formula:
m = (y2 - y1)/(x2 - x1) = (0 - (-3))/(3 - 0) = 3/3 = 1Now, determine whether the relationship between the two triangles you found in the first task is true for any two triangles. For any line, if you draw two right triangles using the line as the hypotenuse, can the triangles be congruent? Why or why not? Do they have to be congruent? Why or why not?
Answer:
They are not congruent based on the drawing. I don't know what they mean by "do they have to be congruent?", as they don't have to be congruent unless the teacher is asking for them to be congruent.
Step-by-step explanation:
Congruency in geometry is defined as identical in form, meaning that it must follow CPCTC (and can be proven in many different ways).
In the case of the given triangles they are not congruent, as DE and AD do not share congruency with BA and CB, respectively. At best, the two given triangles are similar triangles, as ΔADE is a 2x scale factor of ΔCBA.
I am not sure what the question about "do they have to be congruent" is for. Obviously they aren't congruent and so they don't have to be? There is nothing that states they have to be congruent. If you are aiming for congruency, lines AB & CB's measurements would simply have to match that of ED & AD, respectively.
~
Answer:
The relationship we found is that:
The triangles have same vertical/horizontal segment ratio or slope.But this doesn't indicate the triangles are congruent. They have different side lengths which makes them similar but not congruent.
They can be congruent if corresponding sides are of same length.

Challenge in a company, 60% of the workers are men. If 800 people work for the company who aren't men, how many workers are there in all?
Answer:
2000 workers
Step-by-step explanation:
60%= x
40% = 800 (the ones that arent men)
(800÷2= 400) which means..
40%÷2=400
20%=400 so
40% + 20% = 60%
800 + 400 = 1200
now that
60%=1200 workers add the 40percent of workers to the 60% of workers which is (40%=800)
=2000 workers in total

Make x the subject of the formula ax+2d=5cx+3b
Answer:
x = [tex]\frac{3b-2d}{a-5c}[/tex]
Step-by-step explanation:
ax + 2d = 5cx + 3b ( subtract 5cx from both sides )
ax - 5cx + 2d = 3b ( subtract 2d from both sides )
ax - 5cx = 3b - 2d ← factor out x from each term on the left side
x(a - 5c) = 3b - 2d ← divide both sides by (a - 5c)
x = [tex]\frac{3b-2d}{a-5c}[/tex]

Determine the slope of the line that contains the given points. C(1, –7), D(5, 13)
The slope of the line contains the given points. C(1, –7), D(5, 13) is 5 after using the slope formula.
What is the slope?The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have given two points:
C(1, –7) and D(5, 13)
The slope can be found using the slope formula:
[tex]\rm m =\dfrac{13+7}{5-1}[/tex]
m = 20/4
m = 5
Thus, the slope of the line contains the given points. C(1, –7), D(5, 13) is 5 after using the slope formula.
