Answer:
44.4°
Step-by-step explanation:
Two complementary angles add up to 90°. Let's call one of the two x, and the second 90-x (in fact, [tex]x+(90-x) = 90[/tex]).
At this point we can use the second condition: the first angle, plus 1.2°, is equal to the complementary.
[tex]x+1.2=90-x \rightarrow 2x=88.8 \rightarrow x = 44.4[/tex]

consider the following two linear equations 3x+3y=-3 "-3+2y=8"
Answer:
Step-by-step explanation:
3x + 3y = -3 ------------(I)
-3x + 2y = 8 -----------(II)
Add both the equations and x will be cancelled and we can find the value of y
(I) 3x + 3y = -3
(II) -3x + 2y = 8 {Now add}
5y = 5
y = 5/5
y = 1
Now, substitute y = 1 in any of the equations. We are going to substitute in equation (I)
3x + 3*1 = -3
3x + 3 = -3
3x = -3 - 3
3x = -6
x = -6/3
x = -2
The solution of the equation is the point of intersection.
Point of intersection = ( -2, 1)
[tex] - 3 + 2y = 8[/tex]
[tex]2y = 8 + 3[/tex]
[tex]2y = 11[/tex]
[tex]y = \frac{11}{2} [/tex]
Substitute y=11/2 in the first eq:[tex]3x + 3( \frac{11}{2} ) = - 3[/tex]
[tex]3x = 3 - \frac{33}{2} [/tex]
[tex]3x = \frac{6 - 33}{2} [/tex]
[tex]3x = \frac{ - 27}{2} [/tex]
[tex]x = \frac{ - 27}{6} [/tex]

187 minutes and is broken into two parts. The second part of the movie is 11 minutes langer than the first part. How many minutes is Part 2?
Answer:
99 minutes
Step-by-step explanation:
Let the variable x represent the longer part of the movie. Then the shorter part is (x-11) and the total length is the sum of the parts:
187 = x +(x -11)
198 = 2x
x = 99
The length of Part 2 is 99 minutes.

please help this is important for me.
=================================================
Explanation:
Check out the diagram below.
Plot R(-3,7) and T(3,-11) on the same xy grid.
Draw a vertical line through R and a horizontal line through T. A right triangle forms. At the intersection point is point S(-3,-11)
----------------------
Now measure the distance from point S to point T. You can count out the spaces or subtract the x coordinates and use absolute value.
|x1-x2| = |-3-3| = |-6| = 6
From point S to point T is 6 units.
We want to subdivide this horizontal length in the ratio 1:2
What this means is that we want to plot a point U somewhere such that SU:UT = 1:2
In other words,
SU = x
UT = 2x
SU+UT = ST
x+2x = 6
3x = 6
x = 6/3
x = 2
So we must move 2 spaces to the right from point S to get to U(-1,-11)
Going from point U(-1,-11) to T(3,-11) is 4 spaces
We have SU:UT = 2:4 = 1:2 to help confirm we have the correct location for point U
From point U, we then move straight up to the line segment RT
We'll land on Q(-1,1)
----------------------
Another way to find the y coordinate of point Q is to subdivide the segment RS into the ratio 1:2 similar to how we divided ST up
Segment RS is 18 units long since we go from y = 7 to y = -11 when going from R to S.
If V was on segment RS such that
RV:VS = 1:2
and RV = y
then
RV+VS = RS
y+2y = 18
3y = 18
y = 6
RV = y = 6
VS = 2y = 2*6 = 12
So you'll move 6 units down from y = 7 to land on y = 1 (when going from the y coordinate of R to the y coordinate of Q)
find the value of x, y, z in the rhombus below
Answers:
x = -28y = -12z = -11===========================================================
Explanation:
Any rhombus is a parallelogram, but not the other way around.
For any parallelogram, the opposite angles are congruent.
-8y-8 = 88
-8y = 88+8
-8y = 96
y = 96/(-8)
y = -12
Also, for any parallelogram, the adjacent angles are supplementary (meaning they add to 180).
(-3x+8) + (88) = 180
-3x+96 = 180
-3x = 180-96
-3x = 84
x = 84/(-3)
x = -28
And we can also say,
88 + (-9z-7) = 180
-9z+81 = 180
-9z = 180-81
-9z = 99
z = 99/(-9)
z = -11

Answer:
-22
Step-by-step explanation:
First, you must find the values for f(-8) and g(2). f(x) is the blue line so f(-8)=-2 because that is the value of y where x=-8. g(x) is the pink dotted line so g(2)=-4 because that is the value of y where x=2. Then, plug in and solve:
-3(-2)+7(-4)
6+-28

c²=a²+b²
c²=4²+7²
c²=16+49
c²=65
c=√65 or c = 8.06

Select the correct answer from each drop-down menu. what is the equation of the quadratic function represented by this table? x y -3 3.75 -2 4 -1 3.75 0 3 1 1.75 y = (x − )2
The equation of the quadratic function represented by given table is f(x) = -0.25x² -x + 3.
Given table is:
x y
-3 3.75
-2 4
-1 3.75
0 3
1 1.75
Let us say the quadratic function is:
f(x) = ax² +bx + c
What is a quadratic function?
A quadratic function is one of the form f(x) = ax² + bx + c, where a, b, and c are non-zero.
When, x=0, f(x) =3
So, 3 = c
So, f(x) = ax² +bx +3
When, x=1, f(x) =1.75
1.75 = a+b+3
a+b = -1.25........(1)
When, x=-1, f(x) =3.75
3.75 = a-b+3
a-b = 0.75........(2)
Solving equations (1) and (2)
a = -0.25
b = -1
So quadratic function will be:
f(x) = -0.25x² -x + 3
Therefore, the equation of the quadratic function represented by given table is f(x) = -0.25x² -x + 3.

Steven and Bob both have a Pokemon card collection. The number of Pokemon cards in Steven's collection can be represented by x. The number of cards in Bob's collection is 4 times the amount in Steven's collection. The total number of Pokemon cards in both collections is 240. What is the number of cards in Steven's collection?
Answer: 48
Step-by-step explanation:
The number of Pokemon cards in Steven's collection = x
The number of cards in Bob's collection is 4 times the amount in Steven's collection= 4x
The total number of Pokemon cards in both collections = 240
x + 4x = 240
5x = 240
x = 240/5
x = 48
The number of cards in Steven's collection is 48

Answer:
Below.
Step-by-step explanation:
One way is to plot some points:
When x = 0, y = 2(0) - 4 = 4 So plot (0,-4).
In a similar way you can plot when x = 1, y = 2(1) - 4 = -2 that is (1, -2).
Also 2(3) - 4 giving the point (3, 2).
Now draw a line passing through these 3 points.
If you cant draw a line through these points then Ive made a mistake in the calculations
