Given triangle ABC if AB=( 2x-5 ). and AC = (3X -9) Find the value of X if AB = AC
Answer:
x=4
Step-by-step explanation:
if AB = 2x-5 and AC = 3x-9 and AB=AC then:
2x-5 = 3x-9
-x-5=-9
-x=-4
x=4
circle P is representing by the equation (x - 2)^2 + (y + 2)^2 = 9.
plot point P on the given coordinate plane.
Answer:
Solution given.(x - 2)^2 + (y + 2)^2 = 9.
comparing above equation with (x-h)²+(y-k)²=r²
we get
centre(x,y)=(2,-2)
radius [r]=3units

Jesse went out for a 4-course meal were he had a choice of 3 salads, 3 appetizers, 4 entrees, and 5 desserts. How many different four-course meals are possible?
Answer:
180 different four-course meals
Step-by-step explanation:
So you have one out of 3 salads, one out of 3 appetizers, one out of 4 entrees, and one out of 5 deserts. To find the number of meals that are possible, multiply 3 by 3 by 4 by 5
3 * 3 = 9
9 * 4 = 36
36 * 5 = 180

Please show work.
Answer:
This equation has two solutions.
1 solution is: x - 1
Solution #2 is : x - 7
Step-by-step explanation:
1. Move the constant to the left. We end up with x^2 - 8x +7 = 0
2. Rewrite the expression: x^2 - x - 7x + 7 = 0
3. Factor the expressions: x * (x-1) -7(x-1) = 0
4. Separate into possible cases : (x-1) * (x-7) = 0
5. Solve the equation(s): x-1 = 0
x-7 = 0
6. Possible solutions are as follows: x-1 OR x-7
can someone help me with this math problem pls? will give thanks!
Answer:
sin(A) = opp / hyp
=a/hyp. =9/15
cos(A) = adj/hyp
=b/hyp. =12/15
Tan(A) = sin(A) / cos(A)
= 9/15 / 12/15
=9/12. (you can further simplify it)
same for the B angle,
sin(B) = b/15
=12/15
cos(B) = a/15
=9/15
tan(B) = sin(B) / cos(B)
= 12/15 / 9/15
=12/9
MGSE8.G.8: Graph and label triangle PQR whose

What is distance formula?The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On 2D plane the distance between two points (x1, y1) and (x2, y2) is Distance = √[(x2-x1)²+(y2-y1)²].
Using distance formula,
PQ =√[(7+5)²+(-3-2)²]
= √169
= 13 units
QR =√[(7-7)²+(2+3)²]
= √25
= 5 units
RP =√[(-5+7)²+(2-2)²]
= √4
= 2 units
Therefore, the measure of sides of ΔPQR are PQ=13 units, QR=5 units and RP=2 units.

Find the approximate perimeter of the trapezoid? PLSSS HELPPP
Answer:
49
Step-by-step explanation:
side 1 = |18-3|= 15
side 2 = |12-3| = 9
side 3 = |16-4| = 12
side 4: [tex]\sqrt{(18-12)^2 + (4-16)^2} \\ \sqrt{36+144} \\ = \sqrt{180} \\ = 13,4[/tex]
perimeter = 15 + 9 + 12 + 13,4= 49,4 = 49
A line of best fit for a data set has equation y = 3x - 4. What y-value would you predict for an x-value of 8 in this data set?
A 4
B. 8
C. 16
D. 20
Answer:
D. 20
Step-by-step explanation:
The line of best fit for the equation is:
[tex]y = 3x - 4[/tex]
When x = 8
We have to find y. So
[tex]y = 3*8 - 4 = 24 - 4 = 20[/tex]
So the correct answer is given by option D.

After eating dinner at a restaurant, Alex's bill before tax is $78.00. The sales tax rate is 8%. Alex decides to leave a 20% tip for the waiter based on the pre-tax amount. How much money will Alex pay total, including tax and the tip?
Alex's will pay a total of $99.86
Step-by-step explanation:
Tax Rate:
$78.00+8%
8% of $78.00=6.24
78.00+6.24=84.24
Tip:
20% of 78.00=15.6
Total:
(Bill+Tax) 84.24+(Tip)15.6=$99.86

Answer:
i think the answer to this question is 2.461
Step-by-step explanation:
For a semicircle, the total perimeter includes half of the circumference + the diameter.
The half circumference is given by 2 pi r / 2
So the perimeter of 19.02 = 2pi r/ 2 + 2r

HELP CAN SOMEONE HELP ME MATH I'LL GIVE BRAINLIEST
Answer:
Student C wrote the correct inequality
the inequality will be less than or equal to since we want to spend (exactly) 300 or less. We only buy one jacket for 60 dollars so it will be added seperately to the total number of jackets. We are buying multiple jackets and each jacket costs $40. P = # of pants. So the inequality will look like
60 + 40P (less than or equal to symbol) 300
Hope I'm not too late :)
