In the rho.bus, m angle 1 =4y-2. Find the value of y.

Mathematics
1 answer:
IRINA_888 [86]3 years ago
4 0

Answer:

y = 23

Step-by-step explanation:

The diagonals of a rhombus are perpendicular bisectors of each other, thus

∠1 = 90° and ∠1 = 4y - 2, so equating gives

4y - 2 = 90 ( add 2 to both sides )

4y = 92 ( divide both sides by 4 )

y = 23

5. While bird watching, Gabrielle saw 6 robins and 3 blue jays.
Semenov [28]

Answer:

Neither. They both saw the same amount of birds.

Step-by-step explanation:

Gabrielle saw 9 birds, but so did Chase. 6+3 is 9. 3+6 is also 9. The commutative property of addition states that a+b=b+a.

Find the line y=a+bx which best approximates the data points
Vika [28.1K]

Answer:

y = 11.84x - 32.71

Step-by-step explanation:

Here, the given data points,

(−3,−70),(−1,−42),(1,−21),(2,−9),(4,14),

Let x represents the input value and y represents the output value,

So, the table that represents the given situation is,

x         -3            -1             1             2             4

y       -70          -42         -21         -9             14

By the above table,

\sum x=3

\sum y=-128

\sum xy = 269

\sum x^2=31

\sum y^2 = 7382

Let the equation of the line is,

y = bx + a

Where,

a=\frac{\sum y \sum x^2 - \sum x\sum xy}{n(\sum x^2)-(sum x)^2}

b=\frac{n\sum xy - \sum x \sumy}{n(\sum x^2)-(\sum x)^2}

n = number of data points = 5,

By substituting the values we get,

a = - 32.70547945 ≈ - 32.71,

b = 11.84246575 ≈ 11.84,

Hence, the equation of line would be,

y = 11.84x - 32.71

Solve the equation for x.<br> 2/3x-1/9x+5=20
Over [174]

Answer:

x = 27

Step-by-step explanation:

I'm assuming the equation looks like this:

\frac{2}{3}x-\frac{1}{9}x+5=20

Here's how to solve for x:

\frac{2}{3}x-\frac{1}{9}x+5=20

(subtract 5 from both sides)

\frac{2}{3}x-\frac{1}{9}x=15

(Find the GCF of 3 and 9, which is 3. Multiply 2/3 by 3/3. You get 6/9)

\frac{6}{9}x-\frac{1}{9}x=15

(add like terms)

\frac{5}{9}x=15

(multiply 9/5 to both sides, which is the same as dividing both sides by 5/9)

x = 27

Hope it helps (●'◡'●)
