Answer:

y = 10

Step-by-step explanation:

The opposite sides of a parallelogram are congruent, hence

x + 10 = 110 - 4x ( add 4x to both sides )

5x + 10 = 110 ( subtract 10 from both sides )

5x = 100 ( divide both sides by 5 )

x = 20

Using the other pair of congruent sides, then

3y - 10 = 2x - 20 = (2 × 20) - 20 = 40 - 20 = 20, thus

3y - 10 = 20 ( add 10 to both sides )

3y = 30 ( divide both sides by 3 )

y = 10

Given the function f(x) = 2x + 61 - 4, for what values of x is f(x) = 6?
andrezito [222]

Answer: You must have wrote the equation incorrectly

Step-by-step explanation:

You wanna make f(x) equal to 6

So its 6 = 2x + 57

Subtract 57 from both sides to get -51 = 2x

Divide both sides by 2 to get -25.5

Answer:

\overline{BC} \cong  \overline{DC} because corresponding parts of congruent triangles ΔACD and ΔACB are Congruent

Step-by-step explanation:

Statements,                                                Reason

\overline{AC} bisects ∠BCD,                                      Given        

\overline{DC} \perp  \overline{AD}                                                    Given

∠CDA ≅ ∠CBA                                           Right angles are ≅

\overline{AC} \cong  \overline{AC}                                                     Reflexive property

ΔACD ≅ ΔACB                                           Hypotenuse Leg (HL) congrurency

\overline{BC} \cong  \overline{DC}                                                    CPCTC

Where:

CPCTC = Corresponding parts of Congruent Triangles are Congruent

⊥ = Perpendicular to

≅ = Congruent

∠ = Angle

Δ = Triangle.

Solve the system of linear equations. Y=-1/6x+5 and x+6y=30 Can you explain the steps?
aleksklad [387]

Answer:

Infinitely many solutions

Step-by-step explanation:

y = -1/6x + 5

x + 6y = 30

We can solve this system by using substitution or elimination. Since we are given an isolated y-value, I'll be using the substitution method.

Substitute y = -1/6x + 5 into the second equation for y.

  • x + 6(-1/6x + 5) = 30

Distribute 6 inside the parentheses.

  • x - x + 30 = 30

Combine like terms.

  • 30 = 30

Since this is a true statement, we can conclude that this system has a solution of all real numbers, or infinitely many solutions.

We can also see that these equations are indeed equivalent by multiplying the top equation by 6.

6 * (y = -1/6x + 5) → 6y = -x + 30

Adding x to both sides and rearranging terms gives us x + 6y = 30, which is the same as the second equation.
