2. Carl bought some stickers on Saturday. He used 9 of them that same day.
When he went back to the store on Sunday, he bought 3 more stickers.
Write an expression that represents the number of stickers Carl has.
PLEASE HELP ME ASAP
Let N be the number of stickers Carl have and K be the number of stickers he bought at Saturday.
[tex]N = K-9 +3[/tex]
[tex]N = K-6[/tex]
can someone prove this for me please
Please help also can you explain how to answer this if that’s ok?
Answer:
the answer is B
Step-by-step explanation:
you multiply 4 by -5z and 2 and get -20z+8 then you subtract the -6 from 8 and get 2 so -20z+2 a is -20z-2 so its not equivalent but b equals -20z+2 so it's B
what is it called when two lines intersect
Answer:
The point where the lines intersect is called the point of intersection. If the angles produced are all right angles, the lines are called perpendicular lines. If two lines never intersect, they are called parallel lines.
-3 - 4x ≤ 21
Please help!! The first time I got this answer I got x≤ 5.25 but i know it's not right.
I know there are smarties out there. Please help!!
Answer:
lol
Step-by-step explanation:
Yeah i have no clue but good luck
[tex]-3-4x\leq 21 \\~\\-3-4x+3\leq 21+3 \\~\\-4x \leq 24[/tex]
When you multiply both sides by a negative number, you have to flip the inequality.
[tex]-4x\cdot \left(-\dfrac{1}{4}\right) \geq24\cdot \left(-\dfrac{1}{4}\right) \\~\\x \geq-6[/tex]
You could also solve by doing this:
[tex]-4x \leq 24 \\~\\-4x +(4x-24) \leq 24 +(4x-24) \\~\\-24 \leq 4x \\~\\-6\leq x[/tex]
If -6 is less than or equal to x, then x is greather than or equal to -6.
Base and height of a parallelogram 12 cm and 8 cm respectively. find its area
please guys give me correct answer
Answer:
96 cm²
Step-by-step explanation:
Area of a parallelogram A = bh where b = base = 12 cm and h = height = 8 cm.
So, A = 12 cm × 8 cm
A = 96 cm²
So, the area of the parallelogram with base 12 cm and height 8 cm is 96 cm².

put the value of x in inequality and identify.
evaluate sinB given that sinA=-1, a=10 and b=4
Answer:
-2.5
Step-by-step explanation:
Using the sine rule, a/sinA = b/sinB.
So, sinB = bsinA/a
substituting sinA = -1, a = 10 and b = 4, we have
sinB = 10 × (-1)/4
= -10/4
= -5/2
= -2.5
A straight-line graph
• has gradient 4
• crosses the y axis at (0, −3).
Write down the equation of the graph.
Given:
A straight-line graph has gradient 4 and crosses the y axis at (0, −3).
To find:
The equation of the given graph.
Solution:
The slope intercept form of a line is:
[tex]y=mx+b[/tex] ...(i)
Where, m is the slope of the line and b is the y-intercept.
A straight-line graph has gradient 4. It means the slope of the line is 4.
[tex]m=4[/tex]
Line crosses the y axis at (0, −3). So, y-intercept is -3.
[tex]b=-3[/tex]
Putting m=4 and b=-3 in (i), we get
[tex]y=(4)x+(-3)[/tex]
[tex]y=4x-3[/tex]
Therefore, the equation of the given line graph is [tex]y=4x-3[/tex].

Question 1)
Answer:
The slope between (-5, -20) and (9, 9) is:
[tex]m=\frac{29}{14}[/tex]
Step-by-step Explanation
Given the points
(-5, -20)(9, 9)Finding the slope between (-5, -20) and (9, 9)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-5,\:-20\right),\:\left(x_2,\:y_2\right)=\left(9,\:9\right)[/tex]
[tex]m=\frac{9-\left(-20\right)}{9-\left(-5\right)}[/tex]
Refine
[tex]m=\frac{29}{14}[/tex]
Therefore, the slope between (-5, -20) and (9, 9) is:
[tex]m=\frac{29}{14}[/tex]
Question 2
Answer:
the slope between (18, -5) and (18, 20) is undefined.
Step-by-step Explanation
Given the points
(18, -5)(18, 20)As the x-values of the points are the same. It indicates that the given line is vertical.
Finding the slope between (18, -5) and (18, 20)
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [20 - (-5)] / [18 - 18]
= [20+5] / [0]
= 25/0
= ∞ or undefined
Thus, the slope between (18, -5) and (18, 20) is undefined. It indicates that the line is vertical.
Hence, the slope between (18, -5) and (18, 20) is undefined.
Renee calculated 3/6 plus 2/4 and said the answer equaled 5/10. Amanda solved the same problem and said the answer equaled one whole. Whose answer is more reasonable?
Answer:
Amanda's
Step-by-step explanation:
Given :
3/6 + 2/4
The L. C. M of 6 and 4 = 12
(6 + 6) / 12
12 / 12
= 1
Renne's result = 5/10
Amanda's result = 1 whole
Hence, Amanda's result makes more sense.

4x² + 13 – 2y when x = 3 and y = 8
Answer:
The answer is 33.
Step-by-step explanation:
4x^2 + 13 - 2y, x=3 y=8
In order to evaluate this, you just need to plug the x and y in the expression:
= 4(3)^2 + 13 - 2(8)
= 4(9) + 13 - 16
= 36 + 13 - 16
= 33

22 = 5(y – 8) please help me
Answer:
y=12.4
Step-by-step explanation:
22/5 is 4.4
so the numbers in the bracket must equal to 4.4
so y is 12.4
Answer:
62/5 or 12 2/5
Step-by-step explanation:
22 = 5(y-8)
22 = 5y - 40
5y−40=22
Add 40 to both sides
5y−40+40=22+40
5y = 22+40
5y=62
Isolate the variable.
5y/5 = 62/5

Which statement about this system of equations is true?
Answer:
A
Step-by-step explanation:
Mr. Cruz fills a 3-gallon water cooler for a family picnic. He brings plastic cups that each hold 12 fluid ounces of water. How many plastic cups can Mr. Cruz completely fill with the water from the cooler?
One gallon is equivalent to 128 fluid ounces
3 gallons is equivalent to 3*128 fluid ounces
= 384 fluid ounces
One plastic cup can hold 12 guide ounces
So cups needed will be 384/12
32 cups
Mr. Cruz can completely fill 32 plastic cups with the water from the cooler.
What is the division operation?In mathematics, divides left-hand operands into right-hand operands in the division operation.
The 3-gallon water cooler contains 3 x 128 = 384 fluid ounces of water.
We can divide the total amount of water in the cooler by the amount of water each plastic cup can hold to find out how many cups can be completely filled:
384 fluid ounces / 12 fluid ounces/cup = 32 cups
Therefore, he can completely fill 32 plastic cups with the water from the cooler.

Solve for x in the figure below
3x-1
21
167°
Answer:
49
Step-by-step explanation:
167 = 21 + (3x - 1)
167 = 20 + 3x
3x = 147
x = 49
Answer is 49
Step-by-step explanation:
167=(3x-1)+21(Exterior angle is equal to two opposite interior angle)
or,167=3x-1+21
or,167=3x+20
or,167-20=3x
or,147=3x
or,x=147/3
or,x=49

What is the answer to this ?
Answer:
The answer is option 1.
Step-by-step explanation:
In order to solve x, you have to make x the subject, by multiplying each sides by 5, to get rid of 5 on the left side.
[tex] \frac{x}{5} = 8[/tex]
[tex] \frac{x}{5} \times 5 = 8 \times 5[/tex]
