Use a table to find two consecutive integers between which the solution lies.
jolli1 [7]

Answer:

  -5 and -4

Step-by-step explanation:

It is far easier just to solve the equation than to determine appropriate integer bounds on the solution.

In the attachment, we show a couple of initial trials at solutions. The nearness of y=5 to being correct suggests that the next higher integer may be helpful, too. It is.

We find -4 and -5 to bracket the solution.

_____

The actual solution is (3.4 -1.3)/-0.5 = -4.2.

Write an equation in standard form of the line that passes through the given point and has the given slope. (5,0) m=4/3
sveticcg [70]

\text{The standard form of a line:}\ Ax+By=C

\text{The point-slope form:}

y-y_1=m(x-x_1)

\text{We have the point (5, 0) and the slope}\ m=\dfrac{4}{3}

\text{substitute:}\\\\y-0=\dfrac{4}{3}(x-5)\qquad|\text{use distributive property}\\\\y=\dfrac{4}{3}x-\dfrac{20}{3}\qquad|\text{multiply both sides by 3}\\\\3y=4x-20\qquad|\text{subtract 4x from both sides}\\\\-4x+3y=-20\qquad|\text{change the signs}\\\\\boxed{4x-3y=20}

What does y equal when x = -6 in 3x + y = 6<br> What’s the answer
tresset_1 [31]

Answer:

y = 24

Step-by-step explanation:

3x + y = 6

Solve for y

Subtract 3x from each side

3x -3x+ y = 6-3x

y = 6-3x

Let x = -6

y = 6 -3(-6)

   =6+18

   =24

Given the two angles:
Aleksandr [31]

Answer:

congruent, alternate exterior

Step-by-step explanation:

For the first question, the angles are congruent (they are not complementary because they dont add p to 90 degrees, and they are not supplementary because they dont add up to 180 degrees so they must be congrunet)

For the second- they are alternate exterior (i know that they are on the outisde so they are exterior)
