Answer:
x-intercept = 2
Step-by-step explanation:
Sum = 3
Product = -10
Factors = 5 , (-2) {5*(-2) = -10 & 5 +(-2) = 3)
Rewrite the middle term using the factors: 3x = 5x - 2x
x² + 3x - 10 = x² + 5x - 2x - 10
=x(x + 5) - 2(x + 5)
= (x +5)(x - 2)
x² + 8x +15 = x² + 3x + 5x + 15
= x(x + 3) + 5(x + 3)
= (x + 3)(x + 5)
[tex]f(x) =\dfrac{x^{2}+3x -10}{x^{2}+8x + 15}\\\\=\dfrac{(x+5)(x -2)}{(x+5)(x+3)}\\\\=\dfrac{x-2}{x+3)}[/tex]
At x-intercept, y = o
[tex]\dfrac{x -2}{x + 3}=0\\[/tex]
x - 2 = 0
x = 2

[tex]a^{-m}[/tex] = [tex]\frac{1}{a^{m} }[/tex]
g(- 2) = [tex]4^{-2}[/tex] = [tex]\frac{1}{4^{2} }[/tex] = [tex]\frac{1}{16}[/tex]
g(- 1) = [tex]4^{-1}[/tex] = [tex]\frac{1}{4}[/tex]

Find x if the base angles of an isosceles triangle are 61 degrees and 7x+19.
Answers
The question provides the measures of two angles, (one of which contains
a variable), and the relationship between the angles.
The value of x is 6 degrees
Reason:
The given parameters are;
The base angles of the isosceles triangles are; 61° and (7·x + 19)°
Required:
To find the value of x
Solution:
By definition of an isosceles triangle, we have;
The base angles of an isosceles triangle are equal, therefore;
(7·x + 19) = 61
Which gives;
[tex]x = \dfrac{61 - 19}{7} = 6[/tex]
The value of x = 6

Please help complete the table to show the coefficents of each term in the expression
Answers
Answer:
In order from left to right
5,0,0,-4,0,0,8
Step-by-step explanation:
A coefficient is a number that comes before the variable in an equation. First of all, it is important to note that variables that are not present in the equation have a coefficient of 0. This is because 0 times a number is 0; therefore, if a variable is not present it must be multiplied by 0. Additionally, constants can be represented as [tex]x^0[/tex]. Any number raised to the power of 0 is 1. Thus, the coefficient of x^0 is 5 because 1*5=5. Finally, the numbers 8 and -4 appear before [tex]x^6[/tex] and [tex]x^3[/tex], respectfully. Since they come before variables in a term they must be coefficients.

Interior angles of a triangle = 180 degrees.
There are 2 congruent sides so the angle to the right of 67 degrees is also 67 degrees
180 - 2(67) = 46 degrees (the third angle of the triangle)
x + 46 degrees = 90 degrees ( complementary angles)
x = 44 degrees

Goran drove 660 miles in 12 hours.At the same rate, how long would it take him to drive 385 miles?
Answers
Answer:
7 Hour
Step-by-step explanation:
Divide 660 by 12 to get the unit rate.
660 divided by 12 equals 55.
Hence, in 1 hour, Goran drives 55 miles. Next, divide 385 by 55 to get 7.
Therefore,Goran 7 hours to drive 385 miles.
Answer:
Hello, There!
First we have to find Out How fast Goran can go in one hour and If we dived by 660 ÷ 12 = 55
Now We know that Goran Drove [tex]55[/tex] Miles in 1 hour
Since We figured out How fast Goran can go in one miles we can add/multiply to get your final Answer
We can add like this 55, 110, 165, 220, 275, 330, 385
Now we Can Stop because the Question says "Goran drove 660 miles in 12 hours.At the same rate, how long would it take him to drive 385 miles"
And Counting the times we Added we Have the Answer 7
Therefore, It took Goran 7 hours Drive 385 Miles
Write a quadratic function [tex]f[/tex] whose only zero is 12.
Answers
Answer:
f(x) = (x - 12)²Step-by-step explanation:
If a quadratic function has only one zero, then it has multiplicity of two as it is a second degree polynomial and should have two roots. Since one root is a real number, the second root is also a real number being same as the first number.
The function could be:
f(x) = (x - 12)²We know the rule for single zero of quadratic equations
[tex]\\ \sf\longmapsto g(x)=(x-n)^2[/tex]
[tex]\\ \sf\longmapsto g(x)=(x-12)^2[/tex]
