Answer:

y = 90°

Step-by-step explanation:

The left side base angle of the triangle and the angle of 110° form a straight angle and are supplementary, thus

base angle = 180° - 110° = 70°

The right base angle is also 70° , thus the triangle is isosceles

The line segment from the vertex is a perpendicular bisector, hence

y = 90°

Finding the slope in y- intercept form 2×+7y=21

astraxan [27]

To find the slope from an equation, solve the equation for y.
The equation will have the form y = mx + b, called the slope-intercept form.
Then m = slope.

Let's solve your equation for y.

$2x + 7y = 21$

Subtract 2x from both sides.

$7y = -2x + 21$

Divide both sides by 7.

$y = -\dfrac{2}{7} x + \dfrac{21}{7}$

$y = -\dfrac{2}{7} x + 3$

Now compare the equation above to y = mx + b.
m is the number that multiplies x, and it is the slope.

$m = -\dfrac{2}{7}$

You are trying to estimate the average amount a family spends on food during a year. In the past the standard deviation of the a

timama [110]

Answer:

the number of families needed for the survey is 2,157

Step-by-step explanation:

The computation of the number of families needed for the survey is shown below:

Given that

The Standard deviation is $900

Service level = 99%

z value at 99% = 2.58

Expenditures = $50

Based on the above information

The number of families needed for the survey is

$n = (\frac{zs}{E})^2\\\\= (\frac{2.58\times 900}{50})^2$

= 2,157

Hence, the number of families needed for the survey is 2,157

Use substitution to solve the following system of equation s 4y-3= 22 and y=2x-2

Genrish500 [490]

Answer:

x = 33/8

y = 25/4

Step-by-step explanation:

4y - 3 = 22

y = 2x - 2

4y - 3 = 22

4y - 3 - 22 = 0

4y - 25 = 0

4(2x - 2) - 25 = 0

8x - 8 - 25 = 0

8x - 33 = 0

8x = 33

x = 33/8

y = 2x - 2

y = 2(33/8) - 2

y = 33/4 - 2

y = 33/4 - 8/4

y = 25/4
