Answer:
3x + 4
Step-by-step explanation:
We have a product of 3 and x. That's rewritten as 3x. We then have 4 more, so we add 4. That gives us the final answer of: 3x+4. (It is 1-4x for the third one). ( The fourth one) The sum of seven and the quotient of a number x and eight
Here, x be the number.
" quotient of a number x and eight" translated to x/8
Sum means '+'
"sum of seven and the quotient of a number x and eight" translated to 7+ x/8 +56+x/8
then; the given statement is 56+x/8
⇒
Therefore, the given statement is 56+x/8
Answer:45
Step-by-step explanation:
y varies directly as x^2
y=k x x^2
When y=5 x=3
5=k x 3^2
5=k x 9
K=5/9
Relationship is y=5x^2/9
y=(5x9^2) ➗ 9
y=(5x81) ➗ 9
y=405 ➗ 9
y=45
3/4 To find the slope of a line you need to do rise/run. you find two solid points meaning find two points are exactly on a intersection. Then you count up how much it needs to the point then count across to the next point
