By rewriting the linear function we will see that the correct option is A.
"an increasing line that passes through (0, 4)"
Which statement describes the graph?
Here we have the linear function:
2y = 4x + 8
We can rewrite it to get the function in the slope-intercept form:
y = (4x + 8)/2
y = 2x + 4.
So, the slope is positive, this implies that we will have an increasing line.
We also can see that the y-intecept is 4, this means that the line passes through the point (0, 4).
From that, we can conclude that the correct option is A.

Answer:
7. odd angles, 143°; even angles, 37°
8. odd angles, 159°; even angles, 21°
9. even angles, 34°; odd angles, 146°
10. even angles, 29°, odd angles, 151°
Step-by-step explanation:
Angles 1 and 3 are vertical angles, so are congruent. The same can be said of angles 2 and 4. Each odd-numbered angle is supplementary to each even-numbered angle.

7. m∠1 = m∠3 = 143°, m∠2 = m∠4 = 180° -143° = 37°
8. m∠1 = m∠3 = 159°, m∠2 = m∠4 = 180° -159° = 21°
9. m∠2 = m∠4 = 34°, m∠1 = m∠3 = 180° -34° = 146°

Angle θ forms a reference angle that is below the positive x axis (in quadrant IV). What will be the signs on the sine and cosine of angle θ?
Answer:
sin(θ) is negative, cos(θ) is positive
Step-by-step explanation:
Cosine corresponds to the x-coordinate within the unit circle, sine corresponds to the y-coordinate. In quadrant I, they are both positive, in quadrant II, x is negative whilst y is positive, and you would just continue by how they correspond as show in the unit circle, therefore, in quadrant IV, x is positive, y is negative.

First look for the fundamental solutions by solving the homogeneous version of the ODE:
[tex]y''+3y'=0[/tex]
The characteristic equation is
[tex]r^2+3r=r(r+3)=0[/tex]
with roots [tex]r=0[/tex] and [tex]r=-3[/tex], giving the two solutions [tex]C_1[/tex] and [tex]C_2e^{-3t}[/tex].
For the non-homogeneous version, you can exploit the superposition principle and consider one term from the right side at a time.
[tex]y''+3y'=2t^4[/tex]
Assume the ansatz solution,
[tex]{y_p}=at^5+bt^4+ct^3+dt^2+et[/tex]
[tex]\implies {y_p}'=5at^4+4bt^3+3ct^2+2dt+e[/tex]
[tex]\implies {y_p}''=20at^3+12bt^2+6ct+2d[/tex]
(You could include a constant term f here, but it would get absorbed by the first solution [tex]C_1[/tex] anyway.)
Substitute these into the ODE:
[tex](20at^3+12bt^2+6ct+2d)+3(5at^4+4bt^3+3ct^2+2dt+e)=2t^4[/tex]
[tex]15at^4+(20a+12b)t^3+(12b+9c)t^2+(6c+6d)t+(2d+e)=2t^4[/tex]
[tex]\implies\begin{cases}15a=2\\20a+12b=0\\12b+9c=0\\6c+6d=0\\2d+e=0\end{cases}\implies a=\dfrac2{15},b=-\dfrac29,c=\dfrac8{27},d=-\dfrac8{27},e=\dfrac{16}{81}[/tex]
[tex]y''+3y'=t^2e^{-3t}[/tex]
[tex]e^{-3t}[/tex] is already accounted for, so assume an ansatz of the form
[tex]y_p=(at^3+bt^2+ct)e^{-3t}[/tex]
[tex]\implies {y_p}'=(-3at^3+(3a-3b)t^2+(2b-3c)t+c)e^{-3t}[/tex]
[tex]\implies {y_p}''=(9at^3+(9b-18a)t^2+(9c-12b+6a)t+2b-6c)e^{-3t}[/tex]
Substitute into the ODE:
[tex](9at^3+(9b-18a)t^2+(9c-12b+6a)t+2b-6c)e^{-3t}+3(-3at^3+(3a-3b)t^2+(2b-3c)t+c)e^{-3t}=t^2e^{-3t}[/tex]
[tex]9at^3+(9b-18a)t^2+(9c-12b+6a)t+2b-6c-9at^3+(9a-9b)t^2+(6b-9c)t+3c=t^2[/tex]
[tex]-9at^2+(6a-6b)t+2b-3c=t^2[/tex]
[tex]\implies\begin{cases}-9a=1\\6a-6b=0\\2b-3c=0\end{cases}\implies a=-\dfrac19,b=-\dfrac19,c=-\dfrac2{27}[/tex]
[tex]y''+3y'=\sin(3t)[/tex]
Assume an ansatz solution
[tex]y_p=a\sin(3t)+b\cos(3t)[/tex]
[tex]\implies {y_p}'=3a\cos(3t)-3b\sin(3t)[/tex]
[tex]\implies {y_p}''=-9a\sin(3t)-9b\cos(3t)[/tex]
Substitute into the ODE:
[tex](-9a\sin(3t)-9b\cos(3t))+3(3a\cos(3t)-3b\sin(3t))=\sin(3t)[/tex]
[tex](-9a-9b)\sin(3t)+(9a-9b)\cos(3t)=\sin(3t)[/tex]
[tex]\implies\begin{cases}-9a-9b=1\\9a-9b=0\end{cases}\implies a=-\dfrac1{18},b=-\dfrac1{18}[/tex]
So, the general solution of the original ODE is
[tex]y(t)=\dfrac{54t^5 - 90t^4 + 120t^3 - 120t^2 + 80t}{405}\\\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,-\dfrac{3t^3+3t^2+2t}{27}e^{-3t}-\dfrac{\sin(3t)+\cos(3t)}{18}[/tex]
An angle measures 70° more than the measure of its complementary angle. What is the measure of each angle?
Step-by-step explanation:
Let an angle = x
x= 70+(90-x)
x= 160-x
2x=160
x=80
So angle is 80 and it's complementary angle would be 10
Answer:
55∘ and 125∘
Step-by-step explanation:
Supplementary angles sum to
180∘
let one angle be [tex]x[/tex]
then the other angle is [tex]x+70[/tex]
summing the 2 angles gives
[tex]x+x+7=180[/tex]
[tex]2x+70=180[/tex]
subtract 70 from both sides
[tex]2x=180 -70=110[/tex]
divide both sides by
[tex]2x=\frac{110}{2} =55[/tex]
thus the angles are
55∘ and 55 + 70= 125∘

What is the area of the region in the first quadrant bounded on the left by the graph of x=y^2/2 and on the right by the graph of x=3y−4 for 2≤y≤4 ?
The area of the region is -2/3 square units
The area bounded by the regionSince the region is bounded on the left by x = y²/2 and on the right by x = 3y - 4 for 2 ≤ y ≤ 4, the area of the region is given by
[tex]A = \int\limits^4_2 {\frac{y^{2}}{2} } \, dy - \int\limits^4_2 {(3y - 4)} \, dy \\[/tex]
Integrating, we have
A = [y³/6]₂⁴ - [3y²/2 - 4y]₂⁴
A = [4³/6 - 2³/6] - [3(4)²/2 - 4(4) - {3(2)²/2 - 4(2)]}]
A = [64/6 - 8/6] - [3(16)/2 - 16 - {3(4)/2 - 8]}]
A = [64/6 - 8/6] - [3(16)/2 - 16 - {3(4)/2 - 8]}]
A = [64/6 - 8/6] - [3(8) - 16 - {3(2) - 8]}]
A = [(64 - 8)/6] - [3(8) - 16 - {3(2) - 8]}]
A = [56/6] - [24 - 16 - {6 - 8}]
A = [56/6] - [8 - {-2}]
A = [56/6] - [8 + 2]
A = [56/6] - [10]
A = 56/6 - 10
Taking the L.C.M, we have
A = (56 - 10 × 6)/6
A = (56 - 60)/6
A = -4/6
A = -2/3 square units
So, the area of the region is -2/3 square units

what are the x- and y- intercepts for the graph of 3x + y = 15?
Answer:
X intercept=(5,0) and Y intercept=(0,15)
Step-by-step explanation:
3x + y = 15
to find the x int, sub in 0 for y and solve for x
3x + 0 = 15
3x = 15
x = 15/3
x = 5....so the x int is (5,0)
to find the y int, sub in 0 for x and solve for y
3(0) + y = 15
y = 15....so the y int is (0,15)

The area of a baseball field bounded by home plate, first base, second base, and third base is a square. If a player at first base throws the ball to a player at third base, what is the distance the player has to throw? 90 feet is first base 90 feet at third base
Answer:
ta side from one base to next has length of x. so we know each side has length x and the shape they make is a square. This means we are only searching for the diagonal of a square. remember that a diagonal forms and isoscoles right triangle with the 2 sides being equal and the diagonal as the hypotenuse. Using pythagoream theorem we can say
a^2 + b^2 = c^2 all side lengths are x so we can put x in for a and b to get
x^2 + x^2 = c^2
2x^2 = c^2
c = x * squareroot(2)
so if the length between bases is 90 ft
c = 90 ft * squareroot(2)
c = 127.28 ft

Find the slope of -5x+4Y=-16
Given parameters:
Find the slope of the line;
-5x + 4y = -16
To find the slope of this line, we must express it in linear form according to the equation below;
y = mx + c
Where x and y are the coordinates
m is the slope
c is the intercept
Now let us write the given equation in this form;
-5x + 4y = -16
Take add +5x to both sides;
-5x + 4y + 5x = 5x - 16
4y = 5x - 16
Now, divide through by 4;
[tex]\frac{4y}{4}[/tex] = [tex]\frac{5x}{4}[/tex] - [tex]\frac{16}{4}[/tex]
y = [tex]\frac{5x}{4} - 4[/tex]
So the slope of the line is [tex]\frac{5}{4}[/tex]
