Answer:
x-2x = -3 and x = 3
Step-by-step explanation:
Given the expression
y=x+5.... 1
y-2x=2.... 2
Substituting the first equation into the second we will have;
From 2;
y -2x = 2
x+5-2x = 2
x-2x +5 = 2
x-2x = 2-5
x-2x = -3
-x =-3
x =3
Hence the required equation is x-2x = -3 and x = 3
Answer:
(x + 5) – 2x = 2

Which isa zero of the quadratic function f(x) = 4x + 24x + 11?
Ox=9.25
Ox=-5.5
Ox=0.5
Ox=3.25
Answer:
b
Step-by-step explanation:
just took the test edg 22
Option B is correct, -5.5 is the zero of the quadratic function f(x) = 4x + 24x + 11
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .
The given quadratic function is f(x) = 4x²+24x+11
We have to find the zero of the function.
Let us use the quadratic formula to find the zero.
a=4, b=24 and c=11
Let us plug in these values in quadratic formula
x=- 24±√24²-4(4)(11)/8
=-24±√576-176/8
=-24±√400/8
=-24±20/8
=4(-6±5)/8
=(-6+5)/2 or -6-5/2
=-1/2 or -11/2
=-0.5 or -5.5
Hence, Option B is correct, -5.5 is the zero of the quadratic function f(x) = 4x + 24x + 11

-17=x-15 x=-2 How do I show this work tho?
-17 = x - 15
-17 = -2 - 15
Move the 15 over to the -17, the negative becomes a positive.
15-17 = -2
17 - 15 = 2 but since 17 is greater than 15, it's -2
-2 = -2

A caterpillar moves across the grass at a rate of 4 2/3 feet every 7 minutes. How fast does the caterpillar move in feet per minute?
Given:
A caterpillar moves across the grass at a rate of [tex]4\dfrac{2}{3}[/tex] feet every 7 minutes.
To find:
The rate of moving caterpillar in feet per minute.
Solution:
We have,
Distance covered by caterpillar is 7 minutes = [tex]4\dfrac{2}{3}[/tex] feet
Distance covered by caterpillar is 1 minutes = [tex]\dfrac{4\dfrac{2}{3}}{7}[/tex] feet
= [tex]\dfrac{\dfrac{4(3)+2}{3}}{7}[/tex] feet
= [tex]\dfrac{14}{3\times 7}[/tex] feet
= [tex]\dfrac{2}{3}[/tex] feet
Therefore, caterpillar move [tex]\dfrac{2}{3}[/tex] feet per minute.

If you deposit 4,300 into an account with an semi annual interest rate of 11% how much will you have after 1year
Answer:
FV= $4,786.01
Step-by-step explanation:
Giving the following information:
Initial deposit (FV)= $4,300
Number of periods (n)= 2 semesters
First, we need to calculate the semi-annual interest rate:
Semi-annual interest rate= 0.11/2= 0.055
Now, to determine the future value, we need to use the following formula:
FV= PV*(1+i)^n
FV= 4,300*(1.055^2)
FV= $4,786.01
