Algebra i need help asap

=====================================================

Work Shown:

You'll need to use a trig ratio. Specifically, we'll be using cosine here

cos(angle) = adjacent/hypotenuse

cos(x) = 13/20

cos(x) = 0.65

x = arccos(0.65)

x = 49.4583981264954 which is approximate

x = 49

The missing angle is approximately 49 degrees

Make sure your calculator is in degree mode. The notation arccos refers to arccosine and it's the same as inverse sine.

Answer:

answer is x=-2, y=2

Step-by-step explanation:

y=-3x-4,

y=1/2x+3

now plug in any points for x for both equations. I will plug in both x as 0.

y=-3(0)-4

y=-4

(0,-4)

y=1/2(0)+3

y=3

(0,3)

We have points now to plot on a graph.

Continue what I did. Maybe plug in 1 for x for both equations.

Hope this helps!

Answer:

x= [tex]\frac{-8y -6}{7}[/tex]

Step-by-step explanation:

Step 1: Add (-1)/2x to both sides.

−3x − 4y + [tex]\frac{-1}{2}[/tex] x = [tex]\frac{1}{2}[/tex] x + [tex]\frac{-1 }{2}[/tex] x

Step 2: Add 4y to both sides.

[tex]\frac{-7}{2}[/tex] x - 4y + 4y = 3 + 4y

[tex]\frac{-7}{2}[/tex] x = 4y + 3

Step 3: Divide both sides by (-7)/2.

[tex]\frac{-7 }{2}[/tex] x

      = 4y+3

[tex]\frac{-7}{2}[/tex]        [tex]\frac{-7}{2}[/tex]

3) 0

5) 4 Minutes

4) 92,188,000

Question 3:

All numbers multiplied by 0 will always be 0.

So, a(110) × 0 = 0

-----------------------------------------------------------------------------------

Question 5:

100 ÷ 2 = 50 (#of times ÷ # of times)

50 × 5 = 250 (# of times × # of seconds)

250 ÷ 60 = 4.1 (#of total seconds ÷ seconds in a minute)

4.1 Rounded to the nearest tenth is 4.

Answer:

X= [tex]\frac{1}{5\\}[/tex] y+ 1[tex]\frac{-1}{5}[/tex]

Step-by-step explanation:

y=5x+1

Step 1: Flip the equation.

5x + 1

Step 2: Add -1 to both sides.

5x + 1 + −1 = y+ −1

Step 3:

Divide both sides by 5.

[tex]\frac{5x}{5\\}[/tex]= [tex]\frac{y-1}{5}[/tex]

Answer:

8/3 square units.

Step-by-step explanation:

First, visualize the area. You can refer to the attachment below.

To find the area then, we will integrate y from x = 0 to x = 2. Therefore:

[tex]\displaystyle A=\int_0^2x^2\, dx[/tex]

Integrate:

[tex]\displaystyle A=\frac{1}{3}x^3\Big|_{0}^2[/tex]

Evaluate:

[tex]\displaystyle A=\frac{1}{3}[2^3-0^3]=\frac{1}{3}(8)=\frac{8}{3}[/tex]

The area is 8/3 square units.

Answer:

A = [tex]\frac{8}{3}[/tex] units²

Answer:

The original point P is (-1, -5)

Since the original point was reflected over the y axis then you would reflect over the x axis to get the original point and when you reflect over the x axis the x coordinates stay the same and you change the y coordinates to the opposite of what it is

Answer:

D. 19.6in

Step-by-step explanation:

ΔAFC is similar o ΔA'FC'. Therefore, their sides are in ration to one another:

FA/F'A'=AC/A'C'

9/(9+12)=8.4/A'C'

9/21=8.4/A'C'

3/7=8.4/A'C'

A'C'=8.4/(3/7)=19.6

The measure of the angle will be 24 degree.

What is Complementary angle?

When sum of two angles are 90 degrees then the two angles are called Complementary angles.

Given that;

The expression is,

''Twice the complement of an angle is 24 degrees less than its supplement.''

Now,

Let measure of an angle = x degree

The complement of an angle x = (90 - x) degree

The supplement of an angle x = (180 - x) degree

Then, By the given condition we can formulate;

2 ( 90 - x) = (180 - x) - 24

180 - 2x = 180 - x - 24

180 - 2x = 156 - x

Subtract 180 both sides;

180 - 2x - 180 = 156 - x - 180

- 2x = - x - 24

Take negative sign common,

2x = x + 24

Subtract x both side,

2x - x = 24

x = 24

Thus, The measure of the angle will be 24 degree.

Answer:

Step-by-step explanation:

Given the function

f(x) = 4(4x + 3)(x + 1)² (x^2– 3)

The x-intercept occurs at a point where f(x) = 0

f(x) = 4(4x + 3)(x + 1)² (x^2– 3)

4(4x + 3)(x + 1)² (x^2– 3) = 0

4x+3 = 0

4x = -3

x = -3/4

(x + 1)² = 0

x + 1 = 0

x = 0-1

x = -1

x^2-3 = 0

x^2 = 0+3

x^2 = 3

x  = ±√3

hence the x intercepts are -3/4, -1, √3 and -√3. This shows that there are 4 x intercepts

Answer:

The correct classification of the triangle should be considered as the obtuse triangle.

In the obtuse triangle here one of the angle should be considered as the obtuse angle.

In the case when the sum of the squares of the two shorter sides of a triangle should be smaller than the square of the longest side so it considered as the obtuse triangle.

Answer:

Celery = 3/8 cups

Tomatoes = 2/5 cups

Carrot = 5/4 cups

Step-by-step explanation:

CLUE 1: The amounts were 2/5 cup, 3/4 cup, and 5/8 cup

CLUE 2: There is less celery than tomatoes.

CLUE 3: There is less tomatoes than carrots

From clue 2 and 3:

Tomato > Celery ; Carrots > tomatoes

From least to highest :

Celery < Tomatoes < Carrot

Arranging clue 1 in ascending order :

2/5 = 0.4

3/8 = 0.375

5/4 = 1. 25

Hence,

3/8 < 2/5 < 5/4

Celery = 3/8 cups

Tomatoes = 2/5 cups

Carrot = 5/4 cups

Answer:

Step-by-step explanation:

x + y = 47

2x + 3y = 100

Solving steps

x + y = 47 (-2)

2x + 3y = 100

We multiply the first equation by -2. This is so that x changes to -2x (So it would match the x below). We can then cross it over, since the equation below has 2x and -2x + 2x = 0.

-2x - 2y = -94

2x + 3y = 100

Y = 6

We get y = 6 by subtracting -2y (From the above equation) from 3y. This gives us Y. Afterwards, We subtract -94 (From the above equation) from 100 and that gives us 6. Therefore, y = 6.

To get x. We sub in the value for y into one of the equations and solve.

2x + 3(6) = 100

2x + 18 = 100

We bring over 18 from one side to the other, to get x alone. We have to change 18 to - 18 because it crosses over to the other side.

2x = 100 - 18

2x = 72

x = 72÷2

x = 36.

X = 36

Y = 6
