Hi!

We can set up a proportion then cross multiply to solve this.

\frac{45}{x}  \frac{18}{100}

45 x 100 = 4500
4500/18 = 250

The answer is 250

Hope this helps! :)

Determine the factors of 3x2 + 10x − 8. (Which is the right answer?)
VMariaS [17]

ANSWER

(3x  - 2)(x + 4)

EXPLANATION

The given quadratic trinomial is

3 {x}^{2}  + 10x - 8

Comparing to the general quadratic trinomial:

a{x}^{2}  + bx  + c

We have a=1, b=10 and c=-8

ac =  3  \times  - 8 = - 24

The factors of -24 that adds up to 10 are -2 and 12.

We split the middle term to obtain;

3 {x}^{2}   + 12x   - 2x- 8

Factor;

3x(x+ 4)  -  2(x + 4)

Factor further;

(3x  - 2)(x + 4)

The last option is correct.

Answer:

∠ PQR = 70°

Step-by-step explanation:

The tangent- tangent angle PQR is half the difference of the intercepted arcs.

minor arc PR = 360° - 250° = 110°

Then

∠ PQR = \frac{1}{2} (250 - 110)° = \frac{1}{2} × 140° = 70°

Required equation in slope intercept form is: y=5x+4

Step-by-step explanation:

Given

Let m denote the slope of line

m = 5

the line passes though (1,9)

Slope-intercept form of equation of line is:

y= mx+b

Putting m=5 in the equation

y = 5x+b

Putting (1,9) in the equation

9 = 5(1) +b\\9 = 5+b\\b = 9-5\\b = 4

Putting the value of b

y = 5x+4

Hence,

Required equation in slope intercept form is: y=5x+4

Keywords: Equation, linear equation
