To solve 1/8x = -5 , you will need to multiply both sides of the equation by 8. once you do that you will get the answer:
x= -40
let me know if you have any other questions

1/8x = -5

isolate the x, remember that what you do to one side, you do to the other (because of equal sign)
1/8x(8) = -5(8)

x = -5(8)

x = -40

<u>Note:</u> two positive numbers multiplied or divided = positive answer. One negative and one positive number multiplied or divided = negative answer. Two negative numbers multiplied or divided = positive answer


hope this helps

a² + b² = c² This the the formula

(PLUG IN)

8² + b² = 17²

64 + b² = 289 (subtract 64 on both sides)

b² = 225 (square root)

b = 15

Consider the diagram below. Which of the following represent the values of x,y, and z to the nearest hundredth?
astraxan [27]
See the attached figure to better understand the problem

we know that
in the triangle BCD
y²+5.66²=z²-------> y²=z²-5.66²------> equation 1

in the triangle ABC
y²+5.66²=x²-------> y²=x²-5.66²------> equation 2

equals 1 and 2

z²-5.66²=x²-5.66²--------> z²=x²---------> z=x

if z=x then
angle A=45°
angle D=45°

in the triangle ABD
cos 45=z/(5.66*2)-------> z=11.32*cos 45-----> 11.32*√2/2----> 8
z=8
x=8

y²=z²-5.66²------> 8²-5.66²-----> y²=31.96------> y=5.65

the answer is
the value of x is 8
the value of z is 8
the value of y=5.65

explain the steps you would take to determine if the point (4,7) is a solution to the equation y=1.25x+2
enyata [817]

Answer:

Point (4,7) completely satisfies the equation and is a solution to the equation.

Step-by-step explanation:

Given:

Equation: y=1.25x+2

To check if the point (4,7) is a solution to the given equation.

Solution:

The solution of an equation is given as (x,y) which completely satisfies the equation.

To check if the point (4,7) is a solution to the given equation, we will plugin x=4 and y=7 in the given equation and see if it satisfies it or not.

Plugging in point (4,7) in the equation:

7=1.25(4)+2

Simplifying.

7=5+2

7=7

The above equation is always true, and hence point (4,7) completely satisfies the equation and is a solution to the equation.
