Parallel equations have the same slope:
Slope=3

y=3x+b
-3=3 • 6+b
-3= 18 +b
-b= 18+3
b= -21

The equation: y=3x-21

Write an equation of the line that passes through points (3, 7) and (5, 11).

dolphi86 [110]

Answer:

B. y – 7 = 2(x – 3)

Step-by-step explanation:

First, find the the rate of change [slope]:

-y₁ + y₂\-x₁ + x₂ = m

$\frac{-7 + 11}{-3 + 5} = \frac{4}{2} = 2$

Now, according to the Point-Slope Formula, y - y₁ = m(x - x₁), all the negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL inserting the coordinates into the formula with their CORRECT SIGNS.

* Slope = m

Answer:

Step-by-step explanation:

The central angle is twice as big as any angle sharing the endpoints with the central angle of a chord where the angle is not below the smaller sector.

2*62 = x

Order these fractions from least to greatest 3/8, 2/3, 4/5

Ivan

Make all the denominators equal
3/8 = 45/120
2/3 = 80/120
4/5 = 96/120
From least to greatest we have,
3/8, 2/3, 4/5

In the function y = -5x2 + 5 , the graph will open down, be shifted up 5 units, and it will be wider than the parent function y

masya89 [10]

We are considering the function $y=f(x)=-5 x^{2} +5$

the graph of this function is the graph of the parent function $y=g(x)= x^{2}$ after applying the following steps.

1. multiply by -1:

$-x^{2}$ is $x^{2}$ reflected with respect to the x-axis.

2. multiply by 5:

$-5x^{2}$ is $-x^{2}$ shrinked towards the y axis.

for example, consider x=1/2

$-5x^{2}=-5( \frac{1}{2} )^{2}=-5* \frac{1}{4}= \frac{-5}{4}=-1.25$

$-x^{2}=- ( \frac{1}{2} )^{2}=- \frac{1}{4}=-0.25$

now this means that $-5x^{2}$ is "lower" than $-x^{2}$ , which means there is a shrinking of the graph.

3. add 5:

$-5 x^{2} +5$ is $-5 x^{2}$ shifted 5 units up.

4.

so the graph of the function a) opens down, b) is shifted 5 units up, c) is not wider than the parent function
