Answer:

(x + 5) (x - 7)

Step-by-step explanation:

To factor this trinomial, you must split the middle term (-2x) into two terms that can be added to get -2x, and multiplied to get -35:

$x^2$ - 2x - 35

$x^2$ - 7x + 5x - 35

Group:

( $x^2$ - 7x) (5x - 35)

Take out GCF (Greatest Common Factor):

x(x - 7) 5(x - 7)

(x + 5) (x - 7)

I asked more than 10 times Still no steps to a solution

Alisiya [41]

Answer:

C 200

Step-by-step explanation:

It does not appear to be LINEAR so

Start with :

pulse rate = y = 73e^kx

sub in x = .7 when y = 155

155 = 73 e^(.7 * k)

ln ( 155/73) = .7k

.75296567 = .7k

k = 1.07567

for x = 0.9 :

pulse rate = y = 73 e^(1.07567 * .9) = ~ 192 so I expect answer is 200

A line with slope -2/3 passes through the point (-12,16) What is the X-intercept

Troyanec [42]

to find the x-intercept of a function, we simply set y = 0 and then solve for "x", so, let's first find the equation of it and then set y = 0.

$\bf (\stackrel{x_1}{-12}~,~\stackrel{y_1}{16})~\hspace{10em} slope = m\implies-\cfrac{2}{3} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-16=-\cfrac{2}{3}[x-(-12)] \\\\\\ y-16=-\cfrac{2}{3}(x+12)\implies \stackrel{\stackrel{y}{\downarrow }}{0}-16=-\cfrac{2}{3}x-8\implies -8=-\cfrac{2x}{3} \\\\\\ -24=-2x\implies \cfrac{-24}{-2}=x\implies 12=x \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill (12,0) ~\hfill$

Point T is located at (6, –2) and point S is located at (1, 13). What are the coordinates of the point that is 4/5 of the way fr

Darya [45]

Answer:

(2, 10)

Step-by-step explanation:

Making the points on a graph and creating a line between them, you can see the equation to connect the two points is -3x + 16. Then, because the points are 5 units apart horizontally, go to the point that is 4 units left of point T (1/4 of the way between T and S) and that is your point: (2, 10)

I apologize if this is incorrect :)
