X squared + 7 x equals -10

Mathematics
1 answer:
LenKa [72]3 years ago
5 0
Hi there

x² + 7x = -10
x² + 7x + 10 = 0
Now, we can factor left side
(x+2)(x+5) = 0
Set factors equal to 0
x + 2 = 0 or x + 5 = 0
x = 0 - 2 or x = 0 - 5
x = -2 or x =-5


I hope that's help !

The equation of a circle C, with centre O, is:
Nataliya [291]

Answer:

a) The center coordinates O is  (0,0)

b) The radius C = 15

Step-by-step explanation:

The given equation of the circle is : x^{2}  +  y^{2}  = 225

Now, general form of the equation of the circle is:

(x-h)^{2}  + (y - k)^{2}   = r^{2}

where (h,k) are the center co -ordinates and r is the radius of the circle.

Comparing the general equation with the given equation, we get

(x-0)^{2}  + (y - 0)^{2}   = (15)^{2}

So, here the center coordinates (h,k) = (0,0)

And the radius of the given circle is r = 15

Plz help me and plz show work
Flauer [41]

Answer:

21. The slope is 50.

22. 0

23. y=50x

24. $2600

Step-by-step explanation:

21. The slope of the line is 50. Slope is defined as "rise over run". As the line increases, each segment moves up the y-axis by $50, and to the right on the x-axis 1 segment. (Work: 50 divided by 1)

22. The y-intercept is (0, 0), or simply 0. If you look at the graph you can see that the line crosses the y-axis at the origin. This makes the y-intercept equal to 0.

23. The slope tells you that the student makes $50 every week. The y-intercept is 0. Using the formula y=mx+b, an appropriate equation would be y=50x.

24. The equation found in problem 23 can me used to determine how much a student makes (y) after "x" weeks. Substitute 52 for x to solve for y. This becomes y=50(52). This can be simplified to y=2600. This means that after 52 weeks, the student will have made $2,600.
