Step-by-step explanation:
plug in -3x for y
-9x-5(-3x)= -48
-9x+15x= -48. its +15 because negative times negative is.
positive
6x= -48 (-9 +15=6) now divide both sides by 6
x= -8
now you can solve for y by plugging in -8 for x
-3(-8) =y
24= y

The answers for the given Expression are;
1) 15(x+2)
2) -5x + 10
3) 9x - 10
4) 20x - 6
5) 14
6) 21
7) 19
What is an Expression?Numbers, symbols and operators (such as and times) grouped together that show the value of something.
Given are the Expressions to solve;
1) 15x + 30
GCF for this Expression is 15 therefore
15x + 30 = 15(x+2)
2) -5(x - 2) = -5 + 10
3) (8x - 6) - (-x + 4) = 8x - 6 + x - 4 = 9x - 10
4) (11x - 2) + (9x - 4) = 20x - 6
5) 2x - 4y when x = 5 and y = -1
2x - 4y = 2*5 - 4*(-1) = 14
6) x² + 5 when x = 4
4² +5 = 16 + 5 = 21
7) -3y + 12 + 3y + 7 = 19
Hence, The Answers are :
1) 15(x+2)
2) -5x + 10
3) 9x - 10
4) 20x - 6
5) 14
6) 21

Avery is preheating her oven before using it to bake. The initial temperature of the
oven is 65° and the temperature will increase at a rate of 10° per minute after being
turned on. What is the temperature of the oven 7 minutes after being turned on?
What is the temperature of the oven t minutes after being turned on?
Answer:
temp after 7 minutes is 135°
temp after 't' minutes: y = 65 + 10t
Step-by-step explanation:
Answer:
1) 135°
2) 65° + 10t°
Step-by-step explanation:
What is the temperature of the oven 7 minutes after being turned on?
65° (initial temperature) + 10° (temperature increase per minute) × 7 (amount of minutes)
10 × 7 = 70
65° + 70° = 135°
What is the temperature of the oven t minutes after being turned on?
65° (initial temperature) + 10° (temperature increase per minute) × t (amount of minutes)
10 × t = 10t
65° + 10t°

answer this plz maths question
Answer:
Step-by-step explanation:
[tex]\frac{3x + 5}{4x +2}=\frac{3x+4}{4x + 7}[/tex]
Cross multiply,
(3x+ 5 ) (4x + 7)=(3x + 4)*(4x + 2)
3x*4x + 3x *7 + 5*4x + 5*7 = 3x*4x + 3x*2 +4*4x + 4*2
12x² + 21x + 20x + 35 = 12x² + 6x + 16x + 8 {Combine like terms}
12x² + 41x + 35 = 12x² + 22x + 8
12x² + 41x +35 - 12x² - 22x = 8
12x² - 12x² + 41x - 22x + 35 = 8
0 + 19x + 35 = 8
19x = 8 - 35
19x = -27

1+ [-1] - 3 if u answer this i will give u brainly
Answer:
the answer is -3
Step-by-step explanation:
I know life can get hard but don't give up no matter what happens, because you never get anything out of quitting, but you get the most if you keep trying, and trying.
This is what you don't do
Don't let this world make you bitter. Don't let the actions of other people turn you cold on the inside. Certain things happen that hurt us, people come that leave us, and most of all there are moments when you're bound to fall. Don't let those things make you unkind. It's okay to cry. It's okay to be sad. But it's never okay to do other people wrong just because you were done wrong. We're human. We break. We make mistakes. But don't let pain and sadness run your lives. Wake up in the morning and do what you think is right. There are moments in your life where you feel like giving up and you can't take it anymore. It's okay. Breathe. Inhale. Exhale. I know you're weak. But the things that show your weak side are also the same ones that make you stronger in the long run. It's all about taking whatever life throws at you and learning from it.
Hope you like it. Have a great day.

NEED HELP WHAT IS THE SLOPE!!
Answer:2/3
Step-by-step explanation:
Slope is 2/3
y=2x+1
y=4x-1
SHOW YOUR WORK PLEASE
Let's solve your system by substitution.
y=2x+1;y=4x−1
Step: Solve y=2x+1for y:
y=2x+1
Step: Substitute2x+1foryiny=4x−1:
y=4x−1
2x+1=4x−1
2x+1+−4x=4x−1+−4x(Add -4x to both sides)
−2x+1=−1
−2x+1+−1=−1+−1(Add -1 to both sides)
−2x=−2
−2x
−2
=
−2
−2
(Divide both sides by -2)
x=1
Step: Substitute1forxiny=2x+1:
y=2x+1
y=(2)(1)+1
y=3(Simplify both sides of the equation)
Answer:
x=1 and y=3
