7 0

Answer:

15,17,19

Step-by-step explanation:

Make an equation : x+(x+2)+(x+4)=51

Solve the equation:3x+6=51

3x=51-6

3x=45

x=15

Since x=15 then the second number is 17 and then 19

Hope this helps!

What is the discriminant of the polynomial below? 2x^2+3x-7
Katena32 [7]

Answer:

Option C. 65

Step-by-step explanation:

we know that

The discriminant of a quadratic equation of the form ax^{2} +bx+c=0 is equal to

D=b^{2}-4ac

in this problem we have

2x^{2} +3x-7  

so

a=2\\b=3\\c=-7

substitute

D=3^{2}-4(2)*(-7)

D=9+56

D=65

Write the equation 
Shkiper50 [21]
a)\ the\ slope-intercept\ form:\ y=mx+b\\--------------------------\\m=\frac{2}{3}\Rightarrow y=\frac{2}{3}x+b\\\\the\ point\ (-3;\ 6)\Rightarrow \frac{2}{3}\times(-3)+b=6\\\\-2+b=6\ \ \ \ \ |add\ 2\ to\ both\ sides\\\\b=8\\\\\boxed{y=\frac{2}{3}x+8}


b)\ the\ two-points\ formula:y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\-----------------------------\\the\ points:\ (3;-1);\ (5;\ 7)\\\\y-(-1)=\frac{7-(-1)}{5-3}(x-3)\\\\y+1=\frac{7+1}{2}(x-3)\\\\y+1=\frac{8}{2}(x-3)\\\\y+1=4(x-3)\\\\y+1=4x-12\ \ \ \ \ |subtract\ 1\ from\ both\ sides\\\\\boxed{y=4x-13}

Well you could multiply 432 by 0.75, or you can divide it by 4 and then multiply it by 3. Either way your answer is 324.

Use 1% or 10% to estimate 93% of 149<br><br> A. 169.5<br> B. 13.5<br> C. 112<br> D. 135
irakobra [83]
93% of 149

10% of 149 = 14,9

93% of 149 > 90% of 149

93% of 149 > 149 - 14,9 ≈ 149-15≈134
                   > 134
⇒ the answer is D
