Solve -14-5y >-64 A. Y<10 B.y>-10 C. Y>10 D.y<-10

Hello :D

Answer:

A. $Y$

Step-by-step explanation:

First, you add by 14 both sides of an equation.

-14-5y+14>-64+14

Then, simplify by equation.

-64+14=-50

-5y>-50

Multiply -1 both sides.

(-5y)(-1)<(-50)(-1)

5y<50

Divide by 5 both sides of an equation.

5y/5<50/5

Divide numbers from left to right.

50/5=10

y<10 is the correct answer.

Hope this helps you! :D

I need help with multiplying and dividing powers

Tamiku [17]

You need to know these two formulas:

$\huge a^b \times a^c = a^{b+c}\\\\\huge \frac{a^b}{a^c}=a^{b-c}$

For example,

$5^2 \times 5^3 = 5^{2+3} = 5^5$

$\frac{2^6}{2^4} = 2^{6-4} = 2^2$

Donna the trainer has two solo workout plans that she offers her clients: Plan A and Plan B. Each client does either one or the

kykrilka [37]

X=hours of plan A
y=hours of plan B

wed: 5x+6y=12
thu: 3x+2y=6

so
5x+6y=12 and
3x+2y=6
we can eliminate y's by multiplying 2nd equation by -3 and adding to first equation

-9x-6y=-18
5x+6y=12 +
-4x+0y=-6

-4x=-6
divid both sides by -4
x=-6/-4
x=3/2
x=1.5

sub back

3x+2y=6
3(1.5)+2y=6
4.5+2y=6
2y=1.5
y=0.75

Plan A=1.5 hours
Plan B=0.75 hours
