A line passes through the point (-10, -8) and has a slope of -1/2. Write an equation in slope intercept form for this line

1 answer:

7 0

Start with the slope intercept formula.

y = mx + b

Plug in the slope and coordinates for x and y and solve for b (y-intercept)

-8 = -1/2(-10) + b
-8 = 5 + b
-13 = b

Then rewrite the equation in slope intercept form

y = -1/2 x - 13

What is the area of a right triangle with a hypotenuse of 12 and 1 leg is 10??

Agata [3.3K]

Hey there! :)

Area of triangles → (base × height) ÷ 2

The base and height are the 2 legs. You have to find the length of the other leg to find the area, using the Pythagorean Theorem.

a² + b² = c² → c² - a² = b²

c = 12
12² = 12 × 12 = 144

a = 10
10² = 10 × 10 = 100

144 - 100 = 44

√44 = 6.6

Area of triangles → (base × height) ÷ 2

Base: 10
Height: 6.6

6.6 × 10 = 66

66 ÷ 2 = 33

The area is 33

Hope this helps :)

The answer would be C because the y-intercept tells you what y when x is 0. In this case, y is wage and x is years of experience. So, if you have 0 years of experience you get an average of 7.25 dollars per hour, which is C.

Simplify 4a^3 b^2 x 6a^6b^9

Ket [755]

Answer:

24a^9 b^11

Step-by-step explanation:

$4a ^{3} b ^{2} \times 6a ^{6} b ^{9} \\ = (4 \times 6)a ^{3 + 6}b ^{2 + 9} \\ = 24a^{9} b^{11}$
