There are ALOT of equations that can go through the point (7,4). So, pick a slope. it doesnt matter what it is. just pick a number. let us say you pick 3.

Your equation is now y=3x+b.

now you need to find b in respect to (7,4). plug 7 and 4 into the equation and solve for b.
now you have a function that runs through the coordinate (7,4)!

So if it is going completely horizontally, you know that it will begin with the equation y=?. If you use the point (7, 4) then you know that y is 4. Therefore, the answer would be y=4.

What is the sum of all even numbers 0-175 in algebraic form? If n49=99

Mila [183]

Answer:

$S_{88}=7656$

Step-by-step explanation:

We want to find the sum of all even numbers from 0 to 175.

The series will be:

$0+2+4+6+...+174$

The explicit formula for this is $a_n=2n-2$ , where $n\ge1$ .

We need to find how many terms are there.

$2n-2=174$

$2n=176\\n=88$

The sum of terms is given by:

$S_n=\frac{n}{2}(a_1+l)$

Substitute n=88, $a_1=0$ and l=174 to get:

$S_{88}=\frac{88}{2}(0+174)\\S_{88}=44*174\\S_{88}=7656$

All of the following expressions are equivalent except _____.

Andrews [41]

2 - x. because if you replace the x with any number you will get the same answer except for in 2-x. Ex

2 - 4 = -2

4 - 2 = 2

-2 + 4 = 2

4 + (-2) = 2

Why do equivalent ratios form a straight line when graphed? Explain

Anna [14]

Answer:

The y-values of equivalent ratios increase at the same rate as their x-values. The vertical distance between points is constant, and the horizontal distance between points is constant. This forms a straight line.
