Clare made an error when solving – 4x + 3 < 23.
Describe the error that she made.
- 4x + 3 =23
- 4x < 20
Step-by-step explanation:
-4x + 3 < 23
-4x < 20
x > -5
hmm,I don't think we need to put equal sign instead of (<) , for when we started calculating.
we can just keep the question as it is and calculate.
The error Clare made in solving the inequality -4x + 3 < 23 is in the last step. The correct solution should be x > -5, not x < -5.
When dividing or multiplying both sides of an inequality by a negative number, the direction of the inequality symbol should be flipped. In this case, since we are dividing by -4, which is negative, the inequality should be reversed.
The correct steps to solve the inequality are as follows:
-4x + 3 < 23
Subtract 3 from both sides:
-4x < 20
Divide both sides by -4 (remembering to flip the inequality symbol):
x > -5
Therefore, the correct solution is x > -5, indicating that x is greater than -5, not less than -5 as Clare mistakenly wrote.

Answer:
C. -1/2
Step-by-step explanation:
(-2,2)
(0,1)
(2,0)
Change in y = -1
Change in x = 2
Equation: y = -1/2x + 1
The slope of the line is [tex]-\frac{1}{2}[/tex].
Option C is correct.

-2m + 7 < 13 or 5m + 12 > 37
Need help.!!
Answer:
m<-3 or m>5
Step-by-step explanation:
-2m+7<13
-2m<6
m<-3
5m+12>37
5m>25
m>5
The solution of the two expressions will be m<-3 or m>5.
When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.
Given that the two inequalities are -2m + 7 < 13 or 5m + 12 > 37. The inequalities will be solved as,
-2m+7<13
-2m<6
m<-3
5m+12>37
5m>25
m>5
Hence, the solution for the inequalities will be m<-3 or m>5.

-x^2+15x-44
factor the equation
Answer:
- (x - 4)(x - 11)
Step-by-step explanation:
Given
- x² + 15x - 44 ← factor out - 1 from each term
= - 1 (x² - 15x + 44) ← factor the quadratic
Consider the factors of the constant term (+ 44) which sum to give the coefficient of the x- term ( - 15)
The factors are - 4 and - 11 , since
- 4 × - 11 = + 44 and - 4 - 11 = - 15 , thus
x² - 15x + 44 = (x - 4)(x - 11) and
- x² + 15x - 44 = - (x - 4)(x - 11)

A cookie recipe for 60 cookies calls for 4 cups of flour. How much flour is needed to make 90 cookies?
Answer: 6 cups
Step-by-step explanation:
60 cookies = 4 cups
60 + 30 = 90, and half of 60 is 30. So half of 4 cups is 2 cups.
4 cups plus 2 cups is 6 cups!
Answer:
6 cups
Step-by-step explanation:
because if you / the 60 by 4 you would see that 1 cup = 15 cookies. Then add 15 till you get to 90
A company offering short term loans agrees to lend Nick $1,200 . The amount (plus interest) is repayable in one year, and the interest rate is 12% per month. What is the total amount that must be repaid? Give your answer in dollars to the nearest dollar. Do not include commas or the dollar sign in your answer. For example if your answer is $1,234.56 enter 1235 .
Answer:
The total amount is 1214.4
Step-by-step explanation:
Given
principal p=$1200
interest rate r= 12%= 12/100= 0.12
time t= 1
n= 12
we know that the compound interest formula is
A=p(1+r/n )^nt
A=1200(1+0.12/12)^1*12
A=1200(1+0.01)^12
A=1200(1.001)^12
A=1200*1.012
A=1214.
Answer:
Correct answers:
$2928$
Step-by-step explanation:
$2928$
We express the interest r in decimal form, so we have r=12%=12100=0.12. The principal is P0=$1,200, so the interest is I=P0⋅r⋅t=$1,200⋅0.12⋅12=$1,728. The interest paid is $1,728, so the total amount repayable is $1,200+$1,728=$2,928.

Is an imaginary "line" from the Earth to the Moon a line, a ray, or a segment? and WHY?
Answer:
Segment
Step-by-step explanation:
It is a segment because it has two endpoints (the Earth and Moon). If it was a ray, it would go on forever in one direction. It doesn't, so the imaginary line is a segment.
The first image is a segment, the second is a ray.
Hope this helps. :)

A ray goes on forever a segment has end points
What is the missing length of this rectangle?
Answer:
Answer is 11. You have to add the 4 and 7.
In rectangles all sides are either perpendicular or parallel, so you know that the missing side is equal to the bottom 2 horizontal sides added up.
4 + 7 = 11.
The missing side is 11cm.

If UW = 6x - 35, find UW.
Answer:
u= 6x-35/w Hope this helped <3
Step-by-step explanation:
Let's solve for u.
uw=6x−35
Step 1: Divide both sides by w.
Step-by-step explanation:
Answer:-This all will be attempted according to Figure.
We can see in figure ,
[tex]\tt{UW = 4x-20+19}[/tex] _____(1)
Now, question says that:-
[tex]\tt{UW = 6x - 35}[/tex]_______(2)
Equating ,
(1)=(2)
So,
[tex]\tt{4x-20+19 = 6x - 35}[/tex]
[tex]\tt{4x-1 = 6x - 35}[/tex]
[tex]\tt{4x-6x = +1- 35}[/tex]
[tex]\tt{-2x = -34}[/tex]
[tex]\tt{x = \dfrac{34}{2}}[/tex]
[tex]\tt{x = 17}[/tex]
Now, we need UW.
Placing it in any Equation, Let me take (2),
6(17) -35
= 102 - 35
So, 67 is the answer.
Hope it helps :)
