Answer:
C. y = -4x + 1
Step-by-step explanation:
To find the equation for this graph in the formula of a linear equation, y = mx + b, you need 2 things:
the y-intercept, or b;slope, or mb is the y-intercept of the line, so in this case, it would be 1.
m is the slope in the form of [tex]\frac{rise}{run}[/tex], from left to right using a point on the line. If the line goes down from left to right, the slope will be negative, or if the line goes up from left to right, the slope will be positive. In this case, the line goes down 4 and right 1, so the slope is [tex]-\frac{4}{1} = -4[/tex].
Put it together, and you get this equation: y = -4x + 1

Your question is
3*4+2*3-5*2+4*2+6x-2x-3*4+7x-3*3
First calculate each term getting
=12+6-10+8+6x-2x-12+7x-9
Now combine like term which means adding all of the constant together and all of the term containing variable x together
=11x-5
Therefore 11x-5 is the answer to the expression.

Sara's score in the sixth test is 98.
HOW TO CALCULATE TOTAL FROM MEAN?The mean of a set of data can be calculated by dividing the total sum by the number of data given.
According to this question, Sara is said to have a mean score of 62 in 5 tests and another mean score of 68 in 6 tests.
First total score = 62 × 5 = 310Second total score = 68 × 6 = 408Therefore, Sara's score in the sixth test can be calculated by subtracting 310 from 408 to give 98.

The vertex is (−1, −6) .
The graph has a minimum.
Answers
Answer:
graph has a minimum ( looks like V or faces upward )
vertex is (1, −6)
Step-by-step explanation:
*** got to put ^ when typing exponents!!!
y=(x−1)^2−6
y=x^2-2x+1−6
y=x^2-2x-5
basic form is
y = ax^2+bx+c
x vertex = -b/2a
x vertex = -(-2)/2(1)
x vertex = 2/2
x vertex = 1
y vertex = plug x back into the equation
y vertex = y=(1)^2-2(1)-5
y vertex = y=1-2-5
y vertex = y=-6
vertex is (1, −6)
basic form is
y = ax^2+bx+c
if a is positive curve has a minimum means it looks like V or faces upward
if a is negative curve has a maximum means it looks like ^ or faces down
here a is positive so
graph has a minimum

5. 8x + 4y = -5
8x + 4y = 12
Solve it algebraically
Answers
Answer:
solving for x:
8x + 4y = -5
[tex]x = \frac{ - 1}{2} y + \frac{ - 5}{8} [/tex]
and 8x + 4y = 12
[tex]x = \frac{ - 1}{2} y + \frac{3}{2} [/tex]
solving for y:
8x + 4y = -5
[tex]y = - 2x + \frac{ - 5}{4} [/tex]
and 8x + 4y = 12
[tex]y = - 2x + 3[/tex]

50 numbers are written in a row. Every number starting with the third equals the sum of all the preceding numbers. What will you get if you divide the 23rd number by the 15th?
Answers
Assume the first two numbers are A and A
The row will be
A, A, 2A, 4A, 8A
For the nth number in the list it can be represented in the way number=[tex]A*(2)^{n-2}[/tex] for any n≥3
Using this formula the answer of the question can be obtained with division of the 23th and 15th term
[tex]\frac{A*(2)^{23-2}}{A*(2)^{15-2}}[/tex]
Simplify
=[tex]\frac{A*(2)^{21}}{A*(2)^{13}}[/tex]
=[tex]\frac{2^{21}}{2^{13}}[/tex]
=[tex]2^{21-13}[/tex]
=[tex]2^8[/tex]

Do the ordered pairs below represent a relation, a function, both a relation and a function, or neither a relation nor a function?
(-4,0) , (2,-6) , (4,-8) , (10,-14) A. Relation only
B. Neither a relation nor a function
C. Function only
D. Both a relation and a function
Answers
=======================================================
Explanation:
A relation is any set of (x,y) points usually with some rule tying them together. Though that rule doesn't have to be present. We could simply have a set of points. The set of points we are given is a relation.
A function occurs when we don't repeat the x value. Visually if we had two points stacked on top of each other, then we wouldn't have a function since it fails the vertical line test. A function happens when all x inputs leads to exactly one y output. If we had say { (-4,0), (2,-6), (-4,3) } then this wouldn't be a function since x = -4 repeats itself.
Since none of the x values repeat themselves in our given set, this means we have a function.
Side note: Any function is a relation, but not the other way around.
