a right triangle has one angle that measures 80° . what is the measures of the other acute angle?

Answer:

first answer is y = 2x + 2

second answer is y = 1/4x + 6

Step-by-step explanation:

sooo to find the slope you can just count it but i feel like using the equation

y2 - y1 / x2 - x1

is better

so lets substitute

6 - (-6) / 2 - (-4)

6 + 6 / 2 + 4

12 / 6

y = 2x + b

to find b we substitute a point we did not use yet (-2, -2)

-2 = 2(-2) + b

-2 = -4 + b

b = 2

y = 2x + 2

second question:

we do the same thing

(-4, 5) (8, 8)

8 - 5 / 8 - (-4)

3 / 12

1/ 4

y = 1/4x + b

since the graph shows the y intercept (0, 6) we can input it into the equation

y = 1/4x + 6

i cant check it (with a point) because there are not a lot of exact points, but this should be the answer

Answer:

f(3)=1

Step-by-step explanation:

Basically, you go 3 units right on the x-axis starting from the origin (0,0), and go up until you touch the graph of the function. In this case, f(3)=1

Answer:

parallelogram

Step-by-step explanation:

it has 2 parallel sides

Step-by-step explanation:

sin²(x) + cos²(x) = 1

cos²(x) = 1 - sin²(x)

cos(x/2) = ±sqrt((1 + cos(x))/2)

in our case

sin(x) = 1/4, tan(x) > 0, so cos(x) is positive too.

sin²(x) = 1/4² = 1/16

cos²(x) = 1 - 1/16 = 15/16

cos(x) = sqrt(15)/4

cos(x/2) = sqrt((1 + sqrt(15)/4)/2) = sqrt(1/2 + sqrt(15)/8) =

= sqrt(8/16 + 2×sqrt(15)/16) =

= 1/4 × sqrt(8 + 2×sqrt(15))

Answer:

16 cubic units

Step-by-step explanation:

Volume of 1 block = 1 cubic unit

No. of blocks = 16

Total volume = 1  x 16

= 16 cubic units

The total volume of the figure is 16 cubic units if the volume of 1 block is 1 cubic unit.

It is defined as three-dimensional geometry that has six square faces and eight vertices.

We have:

1 block = 1 cubic unit

Total number of blocks = 16

Total volume of the figure = 1×16 = 16 cubic units

Thus, the total volume of the figure is 16 cubic units if the volume of 1 block is 1 cubic unit.

Answer:

the answer is 31!

Step-by-step explanation:

So if you do 12 x 3 that is 36 and 36-5 is 31

so then you see if it works

31 +5 = 36

36/3 = 12

Answer:

number: 31

Let the number be x

This number is added by 5, so: x + 5

Then we divide it total by 3, so: (x + 5)/3

And this equals to 12, (x + 5)/3 = 12

Solve for unknown number:

(x + 5)/3 = 12

x + 5 = 36

x = 36 - 5

x = 31

Answer:

(2, 3 )

Step-by-step explanation:

5x - 4y = - 2 → (1)

2x + 4y = 16 → (2)

add (1) and (2) term by term to eliminate y

7x + 0 = 14

7x = 14 ( divide both sides by 7 )

x = 2

substitute x = 2 into either of the 2 equations and solve for y

substituting into (2)

2(2) + 4y = 16

4 + 4y = 16 ( subtract 4 from both sides )

4y = 12 ( divide both sides by 4 )

y = 3

solution is (2, 3 )

Answer:

( 2 , 3 )

Step-by-step explanation:

5x - 4y = - 2 ⇒ ( 1 )

2x + 4y = 16 ⇒ ( 2 )

( 1 ) + ( 2 )

5x - 4y + 2x + 4y = -2 + 16

7x = 14

Divide both sides by 7.

x = 2

Now let us take equation (1) to find the value of y.

5x - 4y = - 2

5 × 2 - 4y = -2

10 - 4y = -2

-4y = - 2 - 10

-4y = - 12

Divide both sides by ( -4 )

y = 3

Answer:

10

Step-by-step explanation:

say x=0

then y would be 1

increasing x by 5 makes x=5

and then 5 x 2 + 1=11

so y went from 1-11(difference of 10) with the variation

so the answer is 10

Answer:

x ≈ 28°

Step-by-step explanation:

We know the hypotenuse (the longest side) and the opposite (the side opposite x) so we can use SOH:

sine x = opposite ÷ hypotenuse

Substitute in the values:

sin x = 7 ÷ 15

sin x = 0.4666...

Now we can do the inverse of sine to find x:

x = [tex]sin^{-1}[/tex](0.466..)

x = 27.818138... ≈ 28°

Answer:

=

Step-by-step explanation:

3 feet = 1 yard, so knowing this, if you divide 12 feet by 3, you get 4

Another way you could check this is if you multiply the 4 yards by 3 feet per yard. You would get 12 feet.

Either way you do it, they are equal

Answer:

=

Step-by-step explanation:

      I am going to assume that this question is asking us to compare the two measures of distance.

      To do this, we need to convert them into the same unit. I am going to convert 4 yards into feet and leave 12 ft as 12 feet.

4 yards * 3 feet in a yard = 12 feet

Using the reflexive property, 12 feet is equal to 12 feet, so '=' completes this question.

Answer:

5/3, or 1.(6)

Step-by-step explanation:

find slope-intercept form

5x-3y=18

5x=3y+18

3y=5x-18

y=5/3x-6

slope is 5/3, or 1.(6)

The slope is 5/3 or 1.6.

It is the measure of the steepness of a line.

Given that

5x-3y = 18

Rearrange the equation

i.e. 5x-18 = 3y

y = (5/3)x - 6

The general form of the slope-intercept equation is

y = mx+c

By comparing the two equation, we get slope as

Slope of the line,m = 5/3 = 1.6

Hence, the slope of the given line is 1.6.
