Answer:
y = -4x - 6
Step-by-step explanation:
slope-intercept form: y = mx + b
Given: Slope: -4
Point: (-2, 2)
To write an equation in slope-intercept form, we need to know the slope(m) and the y-intercept(b). Since we were given the value of the slope, all we have to do now is find b. To do this, input the given values of m and the point into the equation and solve for b:
y = mx + b
2 = -4(-2) + b
2 = 8 + b
-6 = b
The y-intercept is -6.
Now that we know the slope and the y-intercept, we can write the equation:
y = -4x - 6

Consider the function f(x) = x^3 - 7x^2 - 2x + 14
What is the total number of zeros of f(x)? Explain how you got your answer.
Find the zeros of f(x). Explain your procedure as you solved it.
Answers
Answer:
There are 3 zeros, which are:
[tex]x=7,\:x=-\sqrt{2},\:x=\sqrt{2}[/tex]
Step-by-step explanation:
Given the function
[tex]f\left(x\right)\:=\:x^3\:-\:7x^2\:-\:2x\:+\:14[/tex]
To get the zeros of [tex]f(x)[/tex], set [tex]y[/tex] or [tex]f(x) =0[/tex]
so
[tex]0=x^3-7x^2-2x+14[/tex]
as
[tex]x^3\:-\:7x^2\:-\:2x\:+\:14=\left(x-7\right)\left(x+\sqrt{2}\right)\left(x-\sqrt{2}\right)[/tex]
so
[tex]\left(x-7\right)\left(x+\sqrt{2}\right)\left(x-\sqrt{2}\right)=0[/tex]
Using the zero factor principle:
[tex]\mathrm{ \:If}\:ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)[/tex]
so
[tex]x-7=0\quad \mathrm{or}\quad \:x+\sqrt{2}=0\quad \mathrm{or}\quad \:x-\sqrt{2}=0[/tex]
solving
[tex]x-7=0[/tex]
[tex]x=7[/tex][tex]x+\sqrt{2}=0[/tex]
[tex]x=-\sqrt{2}[/tex][tex]x-\sqrt{2}=0[/tex]
[tex]x=\sqrt{2}[/tex]Therefore, there are 3 zeros, which are:
[tex]x=7,\:x=-\sqrt{2},\:x=\sqrt{2}[/tex]
Larry has $150 in his bank account. He deposits $27 and then writes a check for $96
and a check for $31. How much money is now in his account?
Answers
Answer:
$-4
Step-by-step explanation:
Your welcome
Answer:
$50
Step-by-step explanation:
So the best thing is to com eup with an equation. I came up with:
150 + 27 - 96 - 31
Deposit means to put money into, so that's why we're adding 27.
And then the checks mean that they are going to be taken out of, so that's why we're subtracting 96 and 31. All that's left to do now is solve.
150 + 27 = 177 - 96 = 81 - 31 = 50

[tex]67\frac{7}{10}[/tex] or [tex]67.7[/tex]°
Step-by-step explanation:
First let's interpret the wording. It mentions that on the first day the temperature dropped [tex]10\frac{7}{10}[/tex]. Then on the second day the temperature increased by [tex]12\frac{6}{10}[/tex]. Then they tell us that if the beginning temperature was [tex]65\frac{8}{10}[/tex] what would the temperature be at the end of the of the second day. So since the temperature decreased the first day we should subtract [tex]10\frac{7}{10}[/tex] from [tex]65\frac{8}{10}[/tex]. That will give us [tex]55\frac{1}{10}[/tex]. Now for the second day the temperature increased so we will add [tex]12\frac{6}{10}[/tex] to [tex]55\frac{1}{10}[/tex] and that will give us [tex]67\frac{7}{10}[/tex] and if you want it in a decimal it will be [tex]67.7[/tex].

Answer: 945
Step-by-step explanation: since he is reading 10% MORE you would find the percentage of 450 PLUS 10%
110/100= 1.1
1.1 * 450= 495
495 + 450= 945
