Answer:

y = 4/5x - 18/5

Step-by-step explanation:

y = mx + b

m = 4/5

(2, -2)

-2 = 8/5 + b

b = -10/5 - 8/5 = -18/5

y = 4/5x - 18/5

94 POINTS AND BRAINLIEST TO BEST ANSWER!!!

Schach [20]

Answer:

Step-by-step explanation:

Diagonals are perpendicular so

2x+ 90 + 3x = 180 since this forms a triangle

Combine like terms

5x+ 90 = 180

Subtract 90 from each side

5x +90-90 =180-90

5x = 90

Divide each side by 5

5x/5 = 90/5

x =18

We want to find Angle ABD

ABD = 3x = 3*18 = 54

What is the slope of the line that contains the points (13,-2) and (3.-2)

Allushta [10]

Points are

(13,-2)
(3,-2)

$\boxed{\sf Slope(m)=\dfrac{y_2-y_1}{x_2-x_1}}$

$\\ \sf\longmapsto m=\dfrac{3-13}{-2+2}$

$\\ \sf\longmapsto m=\dfrac{-10}{0}$

$\\ \sf\longmapsto m=0$

pickupchik [31]

Answer:

C) 3.03

Step-by-step explanation:

Step(i):-

Given sample size 'n' = 50

The Mean of the population (μ) = 62

The standard deviation of the Population (σ) = 7

Mean of the sample(x⁻) = 65

Z-score

$Z= \frac{x^{-} -mean}{\frac{S.D}{\sqrt{n} } }$

Step(ii):-

$Z= \frac{65 -62}{\frac{7}{\sqrt{50} } }$

Z = 3.03

Final answer:-

The Z-score = 3.03

The midpoint of DG is M(-1,5). One endpoint is D(1,4). Find the

irina1246 [14]

Answer:

G(-3, 6)

Step-by-step explanation:

$midpoint = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )$

Substitute the coordinates of M and D into the formula:

$( - 1,5) = ( \frac{x1 + 1}{2} , \frac{y1 + 4}{2} ) \\- 1=\frac{x1 + 1}{2}& ,&5&= \frac{y1 + 4}{2} & \\ - 1(2)= x1 + 1&, & 5(2) &= y1 + 4 &\\ - 2= x1 + 1&, &10 &= y1 + 4 &\\ x1= - 2 - 1&,& y1 &= 10 - 4 &\\ x1= - 3&, &y1& =6 \: \: \: \: \: \: \: \: \: \: &$

Thus, the coordinates of G is (-3,6).
