Answer:

y=(5x-3)/4

y=(5/4)x-3/4

Perpendicular slops come from reversing the numerator and denominator and making it negative so the new slope would be:

m=-4/5

Then you use point slope formula and plug in your values:

y-y1=m(x-x1)

y-1=-4/5(x-1)

y=(-4/5)x+9/5

Hope this helps you, have a night day/night.

Evaluate 7+ (-4x^2) for x = 0

algol13

If x is zero then you must replace x with zero and use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction) to solve

7 + (-4(0)^2)

7 + (-4(0))

7 + 0

If x is 0 then the expression equals 7

Hope this helped

16x2 + 40x + 25 FACTOR

vampirchik [111]

Answer: $(4x+5)^2$

Step-by-step explanation:

$16x^2 + 40x + 25$

Rewrite it in the form $a^2+2ab+b^2$ where a=4x and b=5

$(4x)^2+2(4x)(5)5^2$

Use Square of Sum: $(a+b)^2=a^2+2ab+b^2$

$(4x+5)^2$

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY!

Answer:

y = x + 1

Step-by-step explanation:

1) First, find the slope of the line between the two points. Whichever option has the same slope would be the right answer. To find this, use the slope formula $\frac{y_2-y_1}{x_2-x_1}$ . $x_1$ and $y_1$ represent the x and y values of one point, and $x_2$ and $y_2$ represent the x and y values of another point.

So, use the points given to answer the question. Substitute 4 for $x_1$ , 5 for $y_1$ , 8 for $x_2$ , and 9 for $y_2$ then solve:

$\frac{(9)-(5)}{(8)-(4)} \\= \frac{9-5}{8-4} \\= \frac{4}{4} \\= 1$

Therefore, the slope is 1.

2) Any line that is in a "y = a number" format is a horizontal line, and all horizontal lines have a slope of 0 - so the second option can't be the answer.

The rest of the options are in slope-intercept form, or y = mx + b format. Remember that the coefficient of the term with the x is the slope. Knowing this, y = x + 1 would need to be the answer since the coefficient of the term with the x is 1, and we already calculated that the slope is 1.
