A line passes through point (-2, 5) and has a slope of 3. Points A(x 3) and B(-2, y lie on the line.
il63 [147K]

Answer:

x = -8/3

y = 5

Step-by-step explanation:

Finding the equation of the line:

y = 3x +c

Substituting (-2,5) into 'y=3x+c':

5 = -6 + c

c = 11

Hence,

y = 3x + 11

For finding x:

Substituting (x, 3) into 'y = 3x +11':

3 = 3x + 11

3x = -8

x = -8/3

For finding y:

Substituting (-2, y) into 'y = 3x + 11':

y = -6 + 11

y = 5

Solve the following proportion for v. <br>8/5 = v/6 <br>Round your answer to the nearest tenth.​
bekas [8.4K]

Answer:

v=\frac{48}{5}=9\frac{3}{5} \\

Step-by-step explanation:

\frac{8}{5}=\frac{v}{6}

Swap sides:

\frac{v}{6}=\frac{8}{5}

Multiply to both sides by 6:

\frac{v}{6}\cdot6=\frac{8}{5}\cdot6

Group like terms:

\frac{1}{6}\cdot6v=\frac{8}{5}\cdot6

Simplify the fraction:

v=\frac{8}{5}\cdot6

Multiply the fractions

v=\frac{8\cdot6}{5}

Simplify the arithmetic:

v=\frac{48}{5}

Type the correct answer in each box. Use numerals instead of words.

The equation of the quadratic function shown in the graph y - 8 = -2(x + 1)².

<h3>How to illustrate the graph?</h3>

The vertex of this parabola is (-1, 8).  It opens downward, so the x² term has a negative coefficient.  The zeros are (-3, 0) and (1, 0), and the y-intercept is (0, 7).

Through the vertex form of the equation of a parabola we get:

y - (8) = a(x - (-1)) + 7, or.y - 8 = a(x + 1)².

Find coefficient a by substituting the coordinates (-3, 0) in this equation:

0 - 8 = a(-3 + 1)^2, or

-8 = a(-2)² or a = -2

The desired equation is y - 8 = -2(x + 1)^2

16+6-6x-4=-7x+3+7<br>how to solve for x​
Alla [95]

Answer:

x = -8

Step-by-step explanation:

16+6-6x-4=-7x+3+7

Combine like terms

18 -6x = -7x+10

Add 7x to each side

18-6x+7x = -7x+7x+10

18+x = 10

Subtract 18 from each side

18+x-18 = 10-18

x = -8
