Find the zeros of the function
y=x^2-1
Answer:
-1 and 1 are the zeros
Step-by-step explanation:
Graph it and youll see that the curve touches the x axis at (-1,0) and (1,0)
1. −2x + 6 = -16
2. -10 + 5x = -45
Can you help me?
Answer:
for the first one, it's x=11. first, you have to subtract 6 from both sides (-2x+6-6=-16-6) then you simplify that so you get -2x=-22, and from there you divide both sides by -2
getting -2x/-2=-22/-2 then you simplify that and get x=11
and for the second one x=-7. first, you have to add 10 to both sides
(-10+5x+10=-45+10) then simplify that down to 5x=-35 then divide both sides by 5 (5x/5=-35/5) then simplify that down to x=-7

Step-by-step explanation:
Without multiplying or estimating, explain how you can tell which product is greater 6.7x9.31 or 6.7x931
Answer:
We know that the second equation will be greater because there is no decimal point in it but there is a decimal point in the first one with would make the answer much smaller
Answer:
You can tell 6.7x931 is greater
Step-by-step explanation:
You can tell this because 931 is significantly greater than 9.31 so you can immediately tell that 6.7x931 is greater. If this helped you please rate this comment, give it a like, and maybe mark it as branliest!
What is the volume of a rectangular prism containing 96 cubes each with side lengths of 1/2 an inch?
Answer:
12 inches cubed.
Step-by-step explanation:
You find the volume of each small cube (1/2 x 1/2 x 1/2). Then, you multiply that by 96. Then, you have your answer.
Rewrite in simplified exponential notation
Helppp
Answer:
1/4096
Step-by-step explanation:
A negative exponent becomes a fraction. 4*3=12. 2^12=4096, so since it's a negative exponent you put it as a fraction. So it's 1/4096.
The simple exponential notation is 4,096.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The exponential notation is;
⇒ [tex](2^{-4} )^-^3[/tex]
Now, Solve the exponential notation as;
⇒ [tex](2^{-4} )^-^3[/tex] = [tex]2^{-4*-3}[/tex]
= [tex]2^{12}[/tex]
= [tex]4096[/tex]
Hence, The simple exponential notation is 4,096.

Fran is making pair of earrings and a bracelet for four friends. Each pair of earrings uses 4.5 centimeters of wire and each bracelet uses 13 centimeters. Write two equivalent expressions and then find how much total wire is needed.
Answer:
4(4.5+13)=70 cm
And
(4.5+13)+(4.5+13)+(4.5+13)+(4.5+13)=70 cm
I think this one *might* have multiple possibilities but these are just 2 that I can think of
Step-by-step explanation:
There are 4 friends, so whatever you get by adding the bracelet and the earrings, you have to multiply by 4.
4.5+13=17.5
17.5x4=70 cm

Which equation represents the relationship between x-and y-values shown in the table?
Answers:
y = 2x - 1
y = 3x - 4
y = x + 10
y = 2x + 1
4x=3y-2 in slope intercept form
Explain
Answer:
y = 1-1/3x + 2/3
Step-by-step explanation:
Slope-intercept form is y=mx+b
Subtract 3y from both sides to move it to the left side. You now have:
-3y + 4x = -2
Subtract 4x from both sides to move it to the right side. You now have:
-3y = -4x -2
Divide by -3 to get y alone:
y = 1-1/3x + 2/3
Put the equation 3y-4x=-6 into slope intercept form

Brayden is working two summer jobs, making $21 per hour tutoring and making $10 per hour landscaping. In a given week, he can work a maximum of 12 total hours and must earn no less than $170. If xx represents the number of hours tutoring and yy represents the number of hours landscaping, write and solve a system of inequalities graphically and determine one possible solution.
Answer:
2 hours.
Step-by-step explanation:
Money earned for 14 hours of life-guarding = 14*18 = $252. If he worked another 5 hours to make the maximum of 19 he would earn 252 + 5*9
= $297 but he wants to work a minimum of hours for a minimum of 270.
Thus we have the inequality:
252 + 9x ≤ 270
9x ≤ 18
x ≤ 2.
So the number of hours he must do clearing tables = 2.
Answer:
The set of two or more inequalities in one or more variables is referred to as a system of inequalities, and the further discussion can be defined as follows:
System of inequalities:Get y alone on one side of a linear inequality with 2 variables (x,y). Consider the equation that results when the inequality sign is changed to an equality sign. This equation has a line as its graph. A dashed line is drawn if the inequality is strict.From the question, we know
[tex]21 x+10y \geq 170[/tex] money
[tex]x+y \leq 12[/tex] hours
so
Inequality [tex]1 : y\geq - \frac{21}{10} x+17\\\\[/tex]
Inequality [tex]2 : y\leq -x+12\\\\[/tex]
and [tex]x=0, y= 0[/tex]
For example
[tex]y = 2 \ \ \ x=10[/tex]

Antoinette solves the linear equation 3 (x minus 3) + 2 x + 9 = 2 x + 2 (x minus 1) using the steps shown below.
Step 1: 3 x minus 3 + 2 x + 9 = 2 x + 2 (x minus 1)
Step 2: 5 x + 6 = 4 x minus 1
Step 3: 5 x minus 4 x = negative 1 minus 6
