Answer:

Slope=-9, y-intercept=15

Step-by-step explanation:

The slope is always with the x when in slope intercept form, and the y-intercept is the constant (the number with no variable).

Answer:

Slope: 9    y-Intercept Form: 15

Step-by-step explanation:

The formula for slope is y=mx+b. Mx is the slope and b is the y-intercept. Because your equation is written in this form, you can easily find the slope and y-intercept which are 9 and 15. I hope this helps :)

Answer:

y = 2x-7

Step-by-step explanation:

Point-slope equation for line of slope m that passes through (x₀,y₀):

y-y₀ = m(x-x₀)

y-1 = 2(x-4)

Put into slope-intercept form:

y = 2(x-4) + 1

y = 2x - 7

Answer:

m<c = 20º

Step-by-step explanation:

We use these following definitions:

The sum of an interior angle with its exterior is of 180º.

The sum of the three interval angles of a triangle is 180º.

The measure of the exterior angle at point B is 100°.

This means that the measure of the interior angle is: 180 - 100 = 80º

m∠A is 4 times larger than m∠c

This means that the measure of angle c is x, and the measure of angle a is 4x. The other angle, B, is 80º. So

[tex]x + 4x + 80 = 180[/tex]

[tex]5x = 100[/tex]

[tex]x = \frac{100}{5}[/tex]

[tex]x = 20[/tex]

The measure of angle C is 20º.

Answer:

$310

Step-by-step explanation:

200 increase 55% =

200 × (1 + 55%) = 200 × (1 + 0.55) = 310

Answer:

The polynomial is  2 x² - 2x + 7

Step-by-step explanation:

Given polynomial

                   (8 x² + 9 ) - (6x² +2x +2)

           =   8 x² +9 - 6x² - 2x -2

          =    8x² - 6x² - 2x + 9-2

         =    2 x² - 2x + 7

The polynomial is   2 x² - 2x + 7

Answer:

50°

Step-by-step explanation:

the angles should add up to 180. there is a 90° angle abd a 40° angle which adds up to 130. 180-130 gives you rour missing angle if 50°.

9514 1404 393

Answer:

  143°

Step-by-step explanation:

Angle VUT is the sum of the angles into which it is divided.

  ∠VUT = ∠VUA +∠AUT

  ∠VUT = 55° +88°

  ∠VUT = 143°

Answer:

48 square feet

Step-by-step explanation:

Given

Before expansion

[tex]A_1 = \frac{1}{2}bh[/tex] --- area of a triangle

[tex]A_1 = 16ft^2[/tex] --- value of the area

After the base and height were expanded, the area becomes:

[tex]A_2 = \frac{1}{2}BH[/tex]

Where

[tex]B = 2b[/tex]

[tex]H = 2h[/tex]

Substitute 2b for B and 2h for H in [tex]A_2 = \frac{1}{2}BH[/tex]

[tex]A_2 = \frac{1}{2} * 2b * 2h[/tex]

[tex]A_2 = \frac{1}{2} * 2*2*b*h[/tex]

[tex]A_2 = \frac{1}{2} * 4*b*h[/tex]

Rewrite as:

[tex]A_2 = 4 * \frac{1}{2} *b*h[/tex]

[tex]A_2 = 4 * \frac{1}{2}bh[/tex]

Recall that: [tex]A_1 = \frac{1}{2}bh[/tex]

So, we have:

[tex]A_2 = 4 * A_1[/tex]

Substitute 16 for [tex]A_1[/tex]

[tex]A_2 = 4 * 16[/tex]

[tex]A_2 = 64[/tex]

So, the area is [tex]64ft^2[/tex] after the dimensions were expanded

The area increased by:

[tex]Increment = A_2 - A_1[/tex]

[tex]Increment = 64 - 16[/tex]

[tex]Increment = 48[/tex]

It increased by [tex]48ft^2[/tex]

Step-by-step explanation:

Answer:

The 95% confidence interval for the proportion of cans in the shipment that meet the specification is (0.741, 0.917).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

For this problem, we have that:

70 cans, 58 meet the specification for puncture resistance. This means that [tex]n = 50, \pi = \frac{58}{70} = 0.829[/tex]

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.829 - 1.96\sqrt{\frac{0.829*0.171}{70}} = 0.741[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.829 + 1.96\sqrt{\frac{0.829*0.171}{70}} = 0.917[/tex]

The 95% confidence interval for the proportion of cans in the shipment that meet the specification is (0.741, 0.917).
