Answer:

The solution for the equation is $x = 4$ .

Step-by-step explanation:

-Solve the equation:

$2x +5=7x -15$

-Subtract 7x from 2x:

$2x +5 -7x=7x -7x -15$

$-5x + 5=-15$

-Subtract both sides by 5:

$2x + 5 - 5 = -15 -5$

$-5x = -20$

-Divide both sides by -5:

$\frac{-5x}{-5} = \frac{-20}{-5}$

$x = 4$

So, the answer is $x = 4$ .

Step-by-step explanation:

Starting with 2 since its in the hundredths and going over one place to the tenths, we see 7 is greater than 5 so we make the 2 a 3 and replace everything after with 0's

You are given a line that has a slope of 4 and passed through the point (3/8, 1/2). Which statements about the question of the l

alexgriva [62]

Answer:

Statement 1, 2 and 4 are true where as statement 3 is not true.

Step-by-step explanation:

Statement 1: The y-intercept is -1

Point (3/8, 1/2)

Slope = m = 4

y = mx + c

1/2 = 4(3/8) + c

1/2 = 3/2 + c

1/2 = 3/2 + 2c/2

-2 = 2c

c = -1

This statement is true as the y-intercept is -1.

Statement 2: The slope intercept equation is y= 4x - 1

slope = m = 4

y-intercept = c = -1

y = mx + c

y = 4x - 1

This statement is true as the slope intercept equation is y= 4x -1

Statement 3: The point slope equation is y - 3/8 = 4 (x - 1/2)

Point slope equation: y - y1 = m (x - x1)

Points: (x, y) (3/8, 1/2)

y1 = 1/2

x1 = 3/8

Slope = m = 4

y - 1/2 = 4 (x - 3/8)

This statement is not true as the slope intercept equation is y - 1/2 = 4 (x - 3/8) instead of y - 3/8 = 4 (x - 1/2).

Statement 4: The point (3/8, 1/2) corresponds to (x1, y1) in the point slope form of the equation

This statement is true as shown in statement 3's explanation where x1 = 3/8 and y1 = 1/2

The length of the picture would be 10 inches. If the frame needs to be 34, that means 7+7 for the width and 10+10 for the length.

Firlakuza [10]

Part 1) Find the measures of angle BGE
we know that
The inscribed angle measures half of the arc it comprises.
so
angle BGE=(1/2)*[arc EB]

Part 2) Find the angle BDG
we know that
The measure of the external angle is the semi-difference of the arcs that it covers.
so
angle BDG=(1/2)*[arc GEB-arc GB]
