what is the value of -6-(x+3)y when x = -5 and y = 2????

Answers

Answer:

-2

Step-by-step explanation:

Answer: -2

Step-by-step explanation:

Substitute -5 for x and 2 for y in the expression, which gives -6 minus the quantity -5+3, all divided by 2.

Then, use the order of operations to simplify the numerator of the expression. Finally, simplify the fraction, which gives -2. So, when x equals -5 and y equals 2, the expression is equal to -2.

Find the value of x in the triangle shown below.

X=____

Please help!!

Answers

Answer:

62

Step-by-step explanation:

the sum of all angles in a triangle should be 180°

180-56= 124

124÷2= 62

x= 62

Answer:

The sum of the interior angles of a triangle is 180°.

Two sides of the triangle is same, so the their corresponding angles will also be same.

[tex]x + x + 56 = 180 \\ 2x = 180 - 56 \\ 2x = 124 \\ \boxed{x = 62°}[/tex]

62° is the right answer.

Find the equation of the line
passing through the points (5, 2)
and (10, 6).
y =
Xt

Answers

Answer:

y=4/5x-2

Step-by-step explanation:

here are the given points: (5,2) and (10,6)

First, let's find the slope, which is found with the equation (y2-y1)/(x2-x1)

so let's label the points

x1=5

y1=2

x2=10

y2=6

now we can substitute into the equation

m=(6-2)/(10-5)

subtract

m=4/5

so that means the slope is 4/5

Now, let's use point slope form, which is y-y1=m(x-x1) (m is the slope)

so let's substitute the numbers we know from earlier into the equation

y-2=4/5(x-5)

do distributive prop.

y-2=4/5x-4

add 2 to both sides

y=4/5x-2

In AEFG, EF = 44 centimeters and FG = 12 centimeters. Which of the following best describes the possible length, in centimeters, of
AO 44 B. O 32 CO 12 D. 32 < EG < 44

Answers

Answer:

The best inequality describes the possible length of EG is 32 < EG < 56 B

Step-by-step explanation:

In any triangle

The sum of the lengths of any two sides must be greater than the length of the third sideThe length of any side is greater than the difference between the lengths of  the other two sides

In Δ EFG

∵ EF = 44 cm

∵ FG = 12 cm

→ Find their sum and difference

The sum of their length = 44 + 12 = 56 cm

The difference between their length = 44 - 12 = 32 cm

→ By using the rule above

∵ EG is the third side

∴ EG < 56

∴ EG > 32

→ Write them in one inequality

32 < EG < 56

The best inequality describes the possible length of EG is 32 < EG < 56
