Answer:
17
Step-by-step explanation:
add the exponents
the x-intercept was substituted incorrectly
write the correct equation
an equation of the parabola is y =__________
Answer:
Step-by-step explanation:
let the eq. of parabola be
y=ax²+bx+c
points (-1,0),(2,0),(3,4) and (0,-2) lie on it.
0=a-b+c
0=4a+2b+c
subtract
3a+3b=0
a=-b
4=9a+3b+c
-2=0+0+c
c=-2
a-b-2=0
-b-b-2=0
-2b-2=0
b+1=0
b=-1
a=-b=-(-1)=1
eq. of parabola is
y=x²-x-2
solve the compound inequality-8 < 5x + 7 <2
Answer:
-3 < x ≤ -1
Step-by-step explanation:
-8 < 5x + 7 ≤ 2
First, subtract 7 from all sides of the inequality:
-8 - 7 < 5x + 7 - 7 ≤ 2 - 7
-15 < 5x < -5
Divide all sides by 5 to isolate x:
-15 ÷ 5 < 5x ÷ 5 ≤ -5 ÷4
-3 < x ≤ -1
Hope this helps!

*IM CONFUSED??? HELP ME PLEASEE !! , MAKE SURE ITS THE CORRECT ANSWER ITS FOR AN ASSESSMENT ! *
Answer:
First option: y = 5/6x + 12
Step-by-step explanation:
In the slope-intercept form, y = mx + b:
m = represents the slope
b = represents the y-coordinate of the y-intercept, (0, b).
In your given question, it states that the slope (m) = 5/6, and the y-intercept is (0, 12). This means that the value of (b) for your linear equation is the y-coordinate of (0, 12). Therefore, the correct answer is:
y = 5/6x + 12

⚠️⚠️Please help⚠️⚠️ Pip and Ali share S785 in the ratio Pip:Ali = 4:1.
Work out Pip's share.
==========================================================
Work Shown:
x = Ali's share
4x = Pip's share, because it is four times bigger due to the ratio 4:1
x+4x = 5x = total amount of money = 785
5x = 785
x = 785/5
x = 157 dollars is Ali's share
4x = 4*157 = 628 dollars is Pip's share
Note that 157+628 = 785 to help confirm the answer.
Explain why 0.02 x 0.3 = 0.006. Answer in at least 2 complete sentences.
Answer:
.02*.03=.006 because when you multiply decimals after you get your answer you need to move the decimal point over 3 spaces. You do this because when you move the decimal point out three to multiply it you have to move it back in three after you get your solution, or else it is incorrect.
Step-by-step explanation:
1. Refer to the equation 2x − 4y = 12.
(a) Create a table of values for at least 4 points. Show your work on how you found the values for each coordinate pair, and validated the points were on the line.
