Step-by-step explanation:
Select the equation that most accurately depicts the word problem.
Mary Lou has 2 more nickels than pennies, and she has 30 coins all together. Use x for the number of pennies.
a. x + 2 = 30
b. x + (x + 2) = 30
c. 2(x + 2) = 30
d. 2x + 30 = 5
Answer:
B. x + (x+2) = 30
Step-by-step explanation:
If x equals pennies, then one part of the statement should include an addition of 2, along with the additions of the value of pennies; and it should all equal 30.
Answer:
B. x + (x + 2) = 30
Step-by-step explanation:
x = number of pennies
y = number of nickels
x + y = 30
y = 30 - x
She has two more nickels then pennies, therefore:
y = x + 2
30 - x = x + 2
30 = x + x + 2
x + (x + 2) = 30
If x + 2y = 8, and x - y = 5, what is the value of x?
Answer:
x = 6
Step-by-step explanation:
Let's solve y for x + 2y = 8.
x + 2y = 8
2y = -x + 8
y = [tex]-\frac{1}{2}[/tex]x + 4.
Let's solve y for x - y = 5.
x - y = 5
y = x - 5
Since both equations have been solved for y, we can combine them together into one!
x - 5 = [tex]-\frac{1}{2}[/tex]x + 4
x [tex]+ \frac{1}{2}[/tex]x = 4 + 5
1.5x = 9
x = 6

Answer:
44,62, and where is E
Step-by-step explanation:
Part (i)
Angle DBA = 44--------
Reason:
Angle CBA is a right angle (thales theorem), so angle DBA must add to DBC to get 90 degrees. In other words, we solve x+46 = 90 to get x = 44.
============================================================
Part (ii)
Angle DAC = 46--------
Reason:
Both inscribed angles DAC and DBC subtend the same arc (minor arc DC), so the inscribed angles are congruent.
============================================================
Part (iii)
Angle BCE = 74--------
Reason:
Angle BDC is 28 degrees since angle BAC is also 28 degrees (similar reasoning as part ii above). Let y = angle BCD
Focus on triangle BCD. The three interior angles add to 180
B+C+D = 180
46+y+28 = 180
y+74 = 180
y = 180-74
y = 106
Then subtract 180 from this to get the exterior angle BCE
angle BCE = 180-(angle BCD)
angle BCE = 180-y
angle BCE = 74
Or as a shortcut, you could use the remote interior angle theorem
angle BCE = (angle BDC) + (angle DBC)
angle BCE = (28) + (46)
angle BCE = 74

Answer:
c. y = -x + 4
Step-by-step explanation:
Looking at the graph, the trend is decreasing as you move to the right, so you know that the slope has to be negative. Therefore (a) and (d) cannot be the answer since they both have positive slope.
You're only choice left is (b) and (c). (b) can't be the asnwer because averaging out the value at x=0 will give you a value greater than 3, therefore your y-intercept must be some number greater than 3. The only answer choice left is (c).

Given the functions f(x) = x^2 + 6x - 1, g(x) = -x^2 + 2, and h(x) = 2x^2 - 4x + 3, rank them from least to greatest based on their axis of symmetry.
f(x), g(x), h(x)
h(x), g(x), f(x)
g(x), h(x), f(x)
h(x), f(x), g(x)
Answer:
At least to greatest you've got -3, 0, 1 so f(x), g(x), h(x). Answer a
Step-by-step explanation:
ik this is because i am in level 11 grade math
Answer:
h(x), g(x), f(x)
Step-by-step explanation:
I got that value because the axis of symmetry of GX and hx I've got them all the same, one and one the issue comes to the GX where ist has a negative value in front of the X I think when you put a negative value inside a bracket then you Square it you'll get a positive value in the end but since it has a negative value outside then it will be a negative value that is why I considered GX to be smaller than HX but even if I consider GX smaller it's not going to be smaller than FX that is why I got GX and then FX.
Hence, HX then GX then FX

What is the value of x?
Enter your answer in the box.
x =
Step-by-step explanation:
x+55+80=180(sum of triangle)
or,x+135=180
or,x=180-135
or,x=45
Therefore,x=45°
The value of X or angle C is 45 degrees.
Given:
Two angles of triangle ABC are 80 degrees and 55 degrees.
It is required to find the value third angle X of the triangle.
The sum of three angles of a triangle is 180°.
So, the third angle, X, can be calculated as,
[tex]80+55+x=180\\135+x=180\\x=45^{\circ}[/tex]
Thus, we can conclude that the value of X is 45°.

what is the equation of the line that contains the points (3,5) and (7,9)
Answer:
y=x+2
Step-by-step explanation:
The required equation of line will be y = x + 2.
It is given that a line contains points (3,5) and (4,9).
We have to find out the equation of the line.
What is the general equation of a line ?
The equation of a line is y = mx + c.
As per the question line contains points ;
(x1,y1) = (3,5) and (x2,y2) = (7,9) .
Using these points, firstly , we need to find the value of m ;
∵ m = ( y2-y1) / (x2-x1)
m = ( 9-5) / (7-3)
m = 4 / 4
m = 1
We now need to find out the value of c.
Since , (7,9) is on the line this meant this meant value of c is 2.
Putting the value of m and c in general equation of line i.e., y= mx + c
y = 1 × x + 2
y= x + 2
