Answer:
x ≥ −42
Step-by-step explanation:
Let's solve your inequality step-by-step.
x/7≥−6
Step 1: Simplify both sides of the inequality.

Convert 10x + 2y = 30 to slope intercept form by solving for y.
Your answer
Send me a copy of my responses.
Answer:
y = -5x + 15
Step-by-step explanation:
10x + 2y = 30
Subtract 10x from both sides.
2y = -10x + 30
Divide both sides by 2.
y = -5x + 15

Diego is solving the equation x^2-12x = 21
Answer:
The solutions to the quadratic equations will be:
[tex]x=\sqrt{57}+6,\:x=-\sqrt{57}+6[/tex]
Step-by-step explanation:
Given the expression
[tex]x^2-12x\:=\:21[/tex]
Let us solve the equation by completing the square
[tex]x^2-12x\:=\:21[/tex]
Add (-6)² to both sides
[tex]x^2-12x+\left(-6\right)^2=21+\left(-6\right)^2[/tex]
simplify
[tex]x^2-12x+\left(-6\right)^2=57[/tex]
Apply perfect square formula: (a-b)² = a²-2ab+b²
i.e.
[tex]x^2-12x+\left(-6\right)^2=\left(x-6\right)^2[/tex]
so the expression becomes
[tex]\left(x-6\right)^2=57[/tex]
[tex]\mathrm{For\:}f^2\left(x\right)=a\mathrm{\:the\:solutions\:are\:}f\left(x\right)=\sqrt{a},\:-\sqrt{a}[/tex]
solve
[tex]x-6=\sqrt{57}[/tex]
add 6 to both sides
[tex]x-6+6=\sqrt{57}+6[/tex]
Simplify
[tex]x=\sqrt{57}+6[/tex]
also solving
[tex]x-6=-\sqrt{57}[/tex]
add 6 to both sides
[tex]x-6+6=-\sqrt{57}+6[/tex]
Simplify
[tex]x=-\sqrt{57}+6[/tex]
Therefore, the solutions to the quadratic equation will be:
[tex]x=\sqrt{57}+6,\:x=-\sqrt{57}+6[/tex]

Peter made five less than triple as many cookies as Mark did. Let c represent the number of cookies Mark made. Write an expression to determine the number of cookies Peter made
Answer: 3c - 5
Step-by-step explanation:
Since c represent the number of cookies that Mark made. We are then informed that Peter made five less than triple as many cookies as Mark. This will be:
= (3 × c) - 5
= 3c - 5
The expression is 3c - 5

Lainey puts $600 into a GIC for 5 years. The GIC pays 6.2% interest, compounded monthly. How much interest has she earned after 5 years?
Answer:
FV= $819.03
Step-by-step explanation:
Giving the following information:
Initial investment= $600
Number of periods= 5*12= 60 months
Interest rate= 0.062/12= 0.0052
To calculate the future value of the investment, we need to use the following formula:
FV= PV*(1+i)^n
FV= 600*(1.0052^60)
FV= $819.03

JKLM is a rhombus. KM is 20 and JL is 48. Find the perimeter of the
rhombus.
Answer:
104 units
Step-by-step explanation:
Given
Shape: Rhombus
[tex]JL = 48[/tex]
[tex]KM = 20[/tex]
Required
Determine the perimeter
The given parameter are the diagonals of the rhombus.
The perimeter (from diagonals) is calculated as thus:
[tex]P = 2\sqrt{(JL)^2 + (KM)^2}[/tex]
Substitute values for JL and KM
[tex]P = 2\sqrt{48^2 + 20^2}[/tex]
[tex]P = 2\sqrt{2304 +400}[/tex]
[tex]P = 2\sqrt{2704}[/tex]
[tex]P = 2 * 52[/tex]
[tex]P = 104[/tex]
Hence, the perimeter is 104 units

emma's mother started a college fund of emma's 3rd birthday. She deposited $4,500 into an investment account that yields an interest rate of 7.5% compounded annually. If no additional deposits or withdrawals are made, how much will this investment account be worth when emma turns 18 years old?
Answer:
The interest is $1350 and the amount is $5850.
Step-by-step explanation:
STEP 1: Find an interest by using the formula I = P*I*T, where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.
In this example P = $4500, i = 7.5% and t = 4 years, so
4500*0.075*4
I = 1350
STEP 2: Find an amount by using the formula .
Since P = $4500 and I = $1350 we have
$4500 + $1350 = $5850
