Step-by-step explanation:

2n + 19 = 21

2n = 21 - 19

2n = 2

n = 2 \div 2

Therefore, N = 1

Answer:

n=1

Step-by-step explanation:

to solve this you put 19 on the opposite side and subtract 19 fron 21 because subtraction is the opposite of addition and then you get 2 and then divide 2 by 2 to get 1 so n=1. Yo can check it by doing 2*1=2 then 2+19 =21 so it is the correct answer.

Which function represents a parabola that is translated 2 units to the left and 6 units down from the parent function, f(x)=x^2
Luda [366]

Translation involves moving a function along its coordinates

The image of the function is g(x) = (x + 2)^2 - 6

<h3>How to determine the new function</h3>

The parent function is given as:

f(x) = x^2

When the function is translated 2 units left, we have:

f'(x) = (x + 2)^2

When the function is translated 6 units down, we have:

f"(x) = (x + 2)^2 - 6

Rewrite as:

g(x) = (x + 2)^2 - 6

Hence, the image of the function is g(x) = (x + 2)^2 - 6

Write the equation of the line that is parallel to the x-axis and goes through the point (1, 4).
enyata [817]

Answer:

y=4

Step-by-step explanation:

A line that is parallel to the x-axis would have an equation of y= ______.

This is because a horizontal graph has a gradient of zero, thus the value of m in y=mx+c is zero.

y=0x +c

y= c

Since it passed through the point (1,4):

When x=1, y=4,

4= 0(1) +c

c= 4

Thus, the equation of the line is y=4.

A pineaple is 7 times heavy as an orange. The pineaple also weighs 870 grams more than the orange.
Lisa [10]

Answer:

1060 grams

Step-by-step explanation:

let the weight of the orange be x, then

pineapple weighs 7x, and also x + 870

equating the 2 expressions for the weight of the pineapple

7x = x + 870 ( subtract x from both sides )

6x = 870 ( divide both sides by 6 )

x = 145

The orange weighs 145 grams and the pineapple 145 + 870 = 1015 grams

Total weight of both = 145 + 1015 = 1060 grams
