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
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.
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].
HEELLPPPPPPPPPPPP.. I NEED THE ANSWER
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

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
Find the solution of the system of equations.

Submit Answer
Please help me.
Answer:
x=-2 and y=-3
Step-by-step explanation:
2x+4y=-16
-2(-2x+2y=-2)
2x+4y=-16
4x-4y=4
6x=-12
x=-2
2x+4y=-16
2(-2)+4y=-16
-4+4y=-16
+4 +4
4y=-12
y=-3
Answer:
x=-2
y=-3
Step-by-step explanation:
2x=-4y-16 subtract 4y and move to the other side of the equation
x=-2y-8 divide by 2 to isolate x
-2(-2y-8)+2y=-2 plug x into the second equation
4y+16+2y=-2 distribute
6y=-18 combine the Y's and subtract 16 to the other side
y=-3 divide both sides by 6
2x+4(-3)=-16 plug the y value into the first equation to find x
2x-12=-16 distribute (multiply)
2x=-4 add 12 to both sides
x=-2 divide by 2 to get the x value

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.
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]
[tex]x = 40[/tex]

----Directions are provided in the picture-----
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.

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.

you cut a board into pieces that are 1/3 ft long. If the board is 5 ft how many pieces will you have
Answer:
b
Step-by-step explanation:
Answer:
15
Step-by-step explanation:
One foot would have 3 1/3 pieces (because 3 * 1/3 = 1) so that means 5 would have 15 pieces (because 3 * 5 = 15)
Simplify the following expression

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
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.

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.
