The angles of a triangle are in an extended ratio of 5:7:3. What is the measure of the
largest angle?

Answers

Answer:

84°

Step-by-step explanation:

Let the measures of the triangle be 5x, 7x, 3x.

By interior angle sum postulate of a triangle.

5x + 7x + 3x = 180°

15x = 180°

x = 180°/15

x = 12°

7x = 7*12°= 84°

Measure of the largest angle = 84°

When 0.3(4x – 8) – 0.5(–2.4x + 4) is simplified, what is the resulting expression?

A. -4.4
B. 1.2x - 2.4 + 1.2x - 2
C. 2.4x - 0.4
D. 2.4x - 4.4

Answers

Answer:

It's the B

Step-by-step explanation:

0.3*4=1.2

0.3 *(-8)=-2.4

-0.5*(-2.4x)= 1.2x

-0.5*4=-2

So it's 1.2x - 2.4 + 1.2x - 2

Will give reward if right

Answers

Answer:

J = 7.5

Step-by-step explanation:

* This is going off of the estimate that the = sign means the equation is = to 0, as there is no value after the equal sign. *

First, start off by adding all of the like numbers.

11 + (-3) + 7 = 8 + 7 = 15

- 1/8 j - 3/8 j  = - 4/8 j.

Combining those two sums, we get:

15 - 4/8 j = 0

Subtract 15 from both sides,

-4/8 j = -15

Simplify -4/8 to -1/2, and then to -0.5

-0.5j = -15

Divide.

-15/-0.5 = 7.5

When you divide a negative number by another negative number, you get a positive. Therefore, the answer is J = 7.5

If the number after the = sign IS NOT 0, then when you get to 15 - 0.5j, just do the steps but with a number that isn't 0.

(-4, -7) and (-6, 9) in slope-intercept form. Show work

Answers

Answer:

Equation of line in slope-intercept form is: y = -8x-39

Step-by-step explanation:

Given points are:

(-4, -7) and (-6, 9)

The slope-intercept form is given by the equation

[tex]y = mx+b[/tex]

Here m is the slope of the line and b is the y-intercept.

m is found using the formula

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

Here

(x1,y1) = (-4-7)

(x2,y2) = (-6,9)

Putting the values in the formula

[tex]m = \frac{9+7}{-6+4} = \frac{16}{-2} = -8[/tex]

Putting slope in general equation

[tex]y = -8x+b[/tex]

Putting (-6,9) in the equation

[tex]9 = -8(-6)+b\\9 = 48+b\\b = 9-48\\b = -39[/tex]

Putting the value of b we get

[tex]y = -8x-39[/tex]

Hence,

Equation of line in slope-intercept form is: y = -8x-39
