Answer:
yes.
Step-by-step explanation:
The slope is the factor in front of x, so slope is 9.
The y intercept is 7 (that's the point of cross the y axis, where x=0)
There are multiple definitions of "standard form" for lines, so here are the two i can think of:
9x - y = -7 (the implicit function form)
or
y-7 = 9*(x-0) (the point-slope form)
Lmk if you have questions.
Answer:
The sum of a number, which I have named 'n', and 7 can be written as the expression:
n+7
remember the word 'is' in a written problem indicates where you'll most likely use an =,≥,≤ sign. Since they say that it is 'no more than' we know that n+7 is less than or equal to the given number, so we use '≤'.
n+7≤ 1

Answer: (1)
Step-by-step explanation:
A system of equations must have two equations. The first option is the only one that satisfies this.
So, for the semi circle, we need to find the area of a circle then divide it by 2.
pi times r squared
is the area of a circle with the radius of 4
(I'm going to use 3.14 as pi)
So 3.14 times 16 is 50.24
Divide that by 2 and we get 25.12
For the rectangle at the bottom. We know that the radius is four, so we can cut off 4ft from the height, leaving us with 8.
8 times 8 is 64.
To find the area of the whole figure, we add 64 and 25.12 together, getting 89.12
So the area is 89.12 feet squared.
Any questions?
