please help i have a 27 in this class please help

Answers

Answer:

x = 2

Step-by-step explanation:

y=2x so

x=-2x+6

add 2x to both sides

3x=6

divide both sides by 3

x=2

the answer would be x =2

solve system by elimination
6.
2x + 5y = 14
4x + 2 y = -4

Answers

Answer:

x=−3 and y=4

Step-by-step explanation:

Multiply the first equation by -2,and multiply the second equation by 1.

−2(2x+5y=14)

1(4x+2y=−4)

Becomes:

−4x−10y=−28

4x+2y=−4

Add these equations to eliminate x:

−8y=−32

Then solve−8y=−32for y:

−8y=−32

−8y

−8

=

−32

−8

(Divide both sides by -8)

y=4

Now that we've found y let's plug it back in to solve for x.

Write down an original equation:

2x+5y=14

Substitute4foryin2x+5y=14:

2x+(5)(4)=14

2x+20=14(Simplify both sides of the equation)

2x+20+−20=14+−20(Add -20 to both sides)

2x=−6

2x

2

=

−6

2

(Divide both sides by 2)

x=−3

Step by step:
Multiply the first one by -2 to be able to eliminate the x’s
-4x-10y=-28
Add them
-4x-10y=-28
4x+2y=-4
——————-
X’s cancel out your left with
-8y=-32
Divide by -8 to get y alone
Y= 4
Plug in for y to get x
4x+2(4)=-4
4x+8=-4
-8 -8
————-
4x=-12
x=-3

Substitute each variable to determine whether the inequality statement is true or false 16>f if f=17

Answers

Answer: The statement is false.

Step-by-step explanation:

We have the statement:

(16 > f) if  f = 17

In this case:

f = 17 is the hypothesis.

16 > f is the conclusion.

Then assuming that the hypothesis is true, we need to check if the conclusion is also true.

Then:

16 > f  means "16 is larger than f"

Now let's assume that the hypothesis is true, then f = 17, and we can replace this in the inequality above, now we get:

16 > 17

This says "16 is larger than 17"

This is clearly false, then when the hypothesis is true, the conclusion is false.

This means that the statement:

" 16>f if f=17 "

is false.

Which type of triangle will always have at least 1-fold reflectional symmetry?

right triangle
obtuse triangle
acute triangle
isosceles triangle

Answers

Answer:

Isosceles triangle I think

Step-by-step explanation:

The triangle that will always have at least 1-fold reflectional symmetry is the isosceles triangle. That is option D.

What is reflectional symmetry?

Reflectional symmetry is found in geometric shapes that can be folded over onto itself along a line.

The isosceles triangle has only one line of symmetry or 1-fold reflectional symmetry.

Therefore, the triangle that will always have at least 1-fold reflectional symmetry is the isosceles triangle.

Answer:

multiply both sides by 4

Step-by-step explanation:

Given the expression

1/4 x = -10

The first step is to multiply both sides by 4 using the multiplicative property of equality

x * 1 = -40

x = -40

Hence the first step is to multiply both sides by 4
