Y intercept means x = 0, on x= 0 y is also zero so the cordinate is (0,0)

A line with a slope of 8 passes through the points (-1,1) and (0,k). What is the value of k?

Diano4ka-milaya [45]

Answer:

k = 9

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to 8

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 1, 1) and (x₂, y₂ ) = (0, k)

m = $\frac{k-1}{0+1}$ = k - 1 = 8 ( add 1 to both sides )

k = 9

Evaluate the function. f(x) = x² - 4x – 12 Find f(-7)

pashok25 [27]

Answer:

Your answer is 65

Step-by-step explanation:

f(x) = x² - 4x - 12

f(-7) = (-7)² - 4 x (-7) - 12

= 49 - (-28) - 12

= 49 + 28 - 12

= 77 - 12

= 65

Determine whether each set of numbers can be the measure of the sides of a triangle. If so, classify the triangle as acute, righ

ElenaW [278]

The following set of numbers 2√3, 4√2, and 3√5, can be the measures of the sides of an obtuse triangle.

A triangle is a polygon with three sides and three vertices.

To know if a set of number is a valid measure of the sides of a triangle, it must follow the Triangle Inequality Theorem which states that the sum of any two sides must be greater than the third side, such that a + b > c, a + c > b, and b + c > a.

let a = 2√3, b = 4√2, and c = 3√5

a + b > c 2√3 + 4√2 > 3√5 9.12 > 6.71 True

a + c > b 2√3 + 3√5 > 4√2 10.17 > 5.66 True

b + c > a 4√2 + 3√5 > 2√3 12.37 > 3.46 True

To know what type of triangle based on the length of its side:

1. Take the sum of the squares of the two smaller sides.

(2√3)^2 + (4√2)^2 = 44

2. Compare it to the square of the largest side.

(3√5)^2 = 45

44 < 45

If the sum of the squares of the 2 is larger than the square of the 3rd, it is an acute triangle.

if they are equal, it is a right triangle

if they are smaller, then it is an obtuse triangle.

Hence, 2√3, 4√2, and 3√5 can be the measure of the sides of an obtuse triangle.

What is the final amount if 468 is increased by 8% followed by a further 9%

bixtya [17]

Answer:

The final amount is 550.93.

Step-by-step explanation:

Here, the given amount is 468.

Now 8% of the given amount is $\frac{8}{100} \times 468 = 37.44$

⇒ 8% of 468 = 37.44

So, the New amount = Initial Amount + 8% increase

= 468. + 37.44 = 505.44

Now 9 % of the new amount 505.44 is

[tex]\frac{9}{100} \times 505.44 = 45.4896/tex]

⇒ 9% of 505.44 = 45.4896

So, the Final amount = New Amount + 9% increase

= 505.44 + 45.4896 = 550.93

Hence, final amount is 550.93.
