X^2+16-38=0
find what 2 numbers multiply to get -38 and add to get 16
find factors of 38
2 times 19
there is no way to use common factor so use quadratic formula which is
x=
or x=
ax^2+bx+c=0 subsitte
a=1
b=16
c=-38
subsitute
=
=
=
=
so the answers for x are
and
which are aprox -2.099504938362 and +18.099504938362
so it would be
(x-[-8+√102])(x+[8+√102])=0
Answer:
Aidan can expect to save about $17.63 each week.
Step-by-step explanation:
We have an equation: y = 17.63x + 27.52. This equation is in <em>slope-intercept form</em>. In slope-intercept form, the value before the x (in this case, 17.63) is the slope, and the value added to the slope (in this case, 27.52) is the y-intercept.
Right now, though, we only need to focus on the slope. The slope represents a change in y over a change in x. Our y-values represent <em>total amount saved</em>, and our x-values represent <em>number of weeks</em>. Y over x... so, total amount saved over a certain number of weeks.
The first answer seems to match this the best. Remember that the slope represents how much is saved per week, and our slope is 17.63. So, the first answer (Aidan can expect to save about $17.63 each week) is correct. If you have any more questions or that was confusing at all, let me know! :)
4,260 got that by adding 0+0 0+6=6 0+2=2 and 4+0=4 so then u have 4,260
The corresponding sides of the model and the actual bridge are in proportion because the two solids are similar.
The scale factor from the model to the actual bridge is 5/25 = 6/30 = 8/40 = 1/5.
Answer: 1/5
Answer:
Range = {3, -1, 15}
Step-by-step explanation:
Domain = {0,2,-6}
function : y= -2x + 3
We replace the value of x with domain,
when x = 0
y = -2 × 0 + 3
y = 3
When x = 2
y = -2 × 2 + 3
y = -1
When x = -6
y = -2 × -6 + 3
y= 12 + 3
y = 15
