Step-by-step explanation:

so your points are going to be as follows, starting with the left-most point.

(-1, 7)

(0, 4)

(1, 3) [this is the vertex]

(2, 4)

(3, 7)

Step-by-step explanation:

Reference function:

y = x^2

Translated function:

y = a(x - h)^2 + k

k is vertical translation (up if positive or down if negative)

3 in your formula so it move up 3

h is horizontal translation (left if positive or right if negative)

1 in your formula so shifted 1 to the right horizontal translation

a is the vertical scaling

it can be either compressed (more narrow) or streched (wider)

a < 0 the graph is either stretched or compressed and also reflected about the x -axis

none in your formula

What is the equation of the line shown in the graph?

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (-3, 1) and (2, -4). Substitute:

$m=\dfrac{-4-1}{2-(-3)}=\dfrac{-5}{5}=-1$

Therefore we have the equation of a line

$y=-1x+b\to y=-x+b$

Put the coordinates of the point (-3, 1) to the equation:

$1=-(-3)+b$

$1=3+b$ <em>subtract 3 from both sides</em>

$-2=b\to b=-2$

<h3>Answer: y = -x - 2</h3>

Add 5/8 inch, 11/16 inch, and 27/32 inch.

noname [10]

Hi,

Work:

Equation;

$\frac{5}{8} + \frac{11}{16} + \frac{27}{32}$

Write all numerators above the least common denominator 32.

$\frac{5 + 11 + 27}{32}$

Calculate the sum of positive numbers.

$\frac{69}{32}$

Simplify (FRACTION RESULT)

$2 \frac{5}{32}$

Or (DECIMAL RESULT)

$2.15625$

Hope this helps.

Sam and Jeremy have ages that are consecutive odd integers. The product of their ages is 783, which equation could be used to fi

stepladder [879]

(2x+1)=Jeremy´s age
(2x+3)=Sam´s age.
we suggest this equation:
(2x+1)(2x+3)=783
4x²+6x+2x+3=783
4x²+8x-780=0
x²+2x-195=0

We solve this quadratic equation:
x=[-2⁺₋√(4-4*1*(-195))]/2=(-2⁺₋28)/2

x₁=(-2-28)/2=-15 this solution is not valid.
x₂=(-2+28)/2=13

Jeremy´s age=2x+1=2*13+1=27
Sam´s age=2x+3=2*13+3=29
