Simplify the expression.
9(4+t) - 7(t + 3)
9(4 +t) - 7(t + 3) =
Answer:
−63t2−439t−741
Step-by-step explanation:
Let's simplify step-by-step.
9(4+t)−7(t+3)(9)(4+t)−7(t+3)
Distribute:
=(9)(4)+(9)(t)+−63t2+−441t+−756+(−7)(t)+(−7)(3)
=36+9t+−63t2+−441t+−756+−7t+−21
Combine Like Terms:
=36+9t+−63t2+−441t+−756+−7t+−21
=(−63t2)+(9t+−441t+−7t)+(36+−756+−21)
=−63t2+−439t+−741
Can someone help me confused on how to solve but it might be easy I just think I'm dumb

B. 2x5x5x5x5
Step-by-step explanation:
Find the equation of the line passing through the given points. Express the equation in standard form.
(1,-6) and (-7,2)
We want to write the equation of the line passing through these two points in standard form.
First, we are going to do this in slope intercept form and then change the form to standard form, which is Ax + By = C
We will use the equation y = mx + b, and since we are given two points on the line we are going to determine the slope of the line by determining the change in the y coordinates
m = y sub2 - y sub1 divided by the change in the X coordinates x sub2 – x sub1
We will start by determining the slope
(1, -6) the 1 is x sub 1 and the 6 is y sub 1
(-7, 2) the -7 is x sub 2 and the 2 is y sub 2
2 - (-6) = 8
-7 -1 = -8
so equation now is m = -1
So now again referring back to the slope intercept of the line we now know y = -1 + b. We still have to determine b and the y intercept, and we can do this by using one of the given points and substituting in the value for y and x, and then solve for b. Since these points are on the line, they must satisfy this equation. If we use the first coordinates, we would substitute 1 for x and -6 for y.
-6 = -1 times x, which is 1 + b
b = -5
construct the line equation y = mx + b where m = -1 & b = -5
In slope intercept form the equation would be y = -x - 5
Now we want to write this in standard form now. We have to deal with two things. The x and y terms have to be on the left side and A and B and C have to be integers.
The standard form of a linear equation is Ax + By=CA x + By = C . Move all terms containing variables to the left side of the equation.
Add x to both sides of the equation.
y + x = -5
Reorder y & x
x + y = -5
Lana uses factoring by grouping to factor the polynomial 8x2y−10xy2+12x−15y. Her work follows, but the last two lines of work are missing.
Which answers correctly fill in the blanks?
Select two answers: one for blank 1 and one for blank 2.
Answer:
Blank 1: 2xy(4x-5)=3(4x-5)
Blank 2: (2xy+3)(4x-5)
Step-by-step explanation:
The first step in factoring this polynomial is to find the biggest common factor in both numbers inside the parenthesis, and the second step is to find the biggest common factor of the 2 addents.
The other steps are invalid, either because they don't respect positive or negative signs, or that they just factor it wrong completely.
The only correct answer are:
Blank 1: 2xy(4x-5)=3(4x-5)
Blank 2: (2xy+3)(4x-5)

You deposited a check for $1,200 into your checking account that had a balance of $625 and it "bounced". You had written checks for $450, $225, $215, and $187. Your bank will pay the largest check that you wrote first. Your account is overdrawn, and the remaining checks written to pay monthly bills did not clear. Your bank charged you a $35 overdraft fee and each of the remaining creditors receiving bounced checks charged you a $25 late payment fee. What did the $1,200 check that "bounced" on you cost you?
Answer:
total cost = $110
Step-by-step explanation:
Your bank will charge you $35 as overdraft fee.
The bank will only pay one check for $450, so that means that 3 more checks will remained unpaid. Since your creditors charge you $25 per bounced check, then they will charge you 3 x $25 = $75.
Total costs = $35 + $75 = $110
Convert 0.04% to a decimal.
1
Answer:
0.04%x100/100% = 4.0
Step-by-step explanation:
When converting from a percentage to a whole number, multiply it by 100 to return it to a whole number. since it asks for a decimal, it would become 4.0 instead of 4

a line passes trough the points(-5,2) and(10,-1). Wich is the equation of the line
Answer:
y= -(1/5)x +1
Step-by-step explanation:
Find slope:
(2+1)/(-5-10) = -1/5
Plug a point and slope into equation (I used -5,2):
y-2=-1/5(x+5)
Change it to slope-intercept form:
y-2=-1/5(x+5)
y-2=-1/5x-1
y=-1/5x+1

Jenny ran 5 more miles this week than she ran last week. Let t be the number of miles she ran last week. Write an expression that tells how many miles she ran this week.
Answer:
t+5+x
Step-by-step explanation:
It says Jenny ran 5 more miles than last week so you find the number from last week then add 5. X is the miles she ran this week
Answer:
t + 5
Step-by-step explanation:
In this problem, you have to recognize what the information is telling you in terms of the vocabulary used. For example, the first sentence tells us that she ran 5 more miles than last week. This is key because it lets us know that our expression will have an addition sign.
Once you recognize that the problem is telling you to add 5 to her previous distance, you get a final expression of t + 5. Hope this helps!

the square root of 39 is between which 2 integers
9514 1404 393
Answer:
6 and 7
Step-by-step explanation:
6² = 36
(√39)² = 39
7² = 49
The square root of 39 is between 6 and 7.
Solve for x in the equation x squared + 10 x + 12 = 36.
x = –12 or x = 2
x = –11 or x = 1
x = –2 or x = 12
Answer:
x= -12 x=2
