Answer (if we're solving for x):
[tex]x=-7[/tex] or [tex]\frac{9}{2}[/tex]
Step-by-step explanation:
Rearrange the terms from [tex]2x^{2} =63-5x[/tex] to [tex]2x^{2}=-5x+63[/tex]Move the terms to the left side: [tex]2x^{2}-(-5x+63)=0[/tex]Use the "sum-product" pattern: [tex]2x^2+14x-9x-63=0[/tex]Get the common factor drom the 2 pairs:[tex]2x(x+7)-9(x+7)=0[/tex]Rewrite the equation in factored form as [tex](2x-9)(x+7)=0[/tex]Create 2 equations from [tex](2x-9)(x+7)=0[/tex]: [tex]2x-9=0\\x+7=0[/tex]This means that [tex]x[/tex] can either be [tex]-7 (-7+7=0=x+7)[/tex] or [tex]\frac{9}{2} (\frac{8}{2}=4; \frac{9}{2}=4.5)[/tex]find AB and BC with the help of given in figure complete following activity
Answer:
let base side be x=AB=BC
by using Pythagoras law
h²=p²+b²
(√8)²=x²+x²
8=2x²

Answer:
∠ABC = 54°
Step-by-step explanation:
an inscribed angle is 1/2 the size of an incenter angle.
so:
∠AMC = 2(∠ABC)
10x - 12 = 2(4x + 6)
10x - 12 = 8x + 12
simplify:
2x = 24
x = 12
∠ABC = 4(12) + 6 = 54°

how would i graph
y=− 5/2x-3
and
x−y=−4
(_,_)
Given:
The system of equations is
[tex]y=-\dfrac{5}{2}x-3[/tex]
[tex]x-y=-4[/tex]
To find:
The graph of the given system of equations and its solution.
Solution:
The table of values for [tex]y=-\dfrac{5}{2}x-3[/tex] is
x y
-4 7
-2 2
0 -3
Plot these points and connect them by a straight line.
The table of values for [tex]x-y=-4[/tex] is
x y
-4 0
-2 2
0 4
Plot these points and connect them by a straight line.
From the below graph it is clear that the lines intersect each other at point (-2,2).
Therefore, the solution of given system of equation is (-2,2).

can someone help please 13 points and those are the only answer options for all 4
Answer:
1 - x-axis, 2 - y-axis, 3 - y-axis, 4 - x-axis
Step-by-step explanation:
4x+a=4x+3. How do you get to 6? Please explain and write down like you would write on paper.
Answer:
a=3 x= all reals
Step-by-step explanation:
I actually did not get 6 for an answer
4x+a=4x+3
cancel equal terms on both sides of the equation
a=3
which means the x would be all reals cause it is true.

Answer:
J 3/4 cup
Step-by-step explanation:
Step 1: read and understand the question.
The question is giving you amounts of flour and 2 types of sugar.
The question is asking for a difference between two quantities:
the amount of flour (2 1/4 cups)the combined amount of sugar (3/4 cup white, 3/4 cup brown)Step 2: determine the relations you need to use to solve the problem
You need the combined amount of sugar, which you find by adding the quantities of each of the kinds.
3/4 cup white + 3/4 cup brown = 6/4 cup sugar combined
You need the difference of that quantity from the quantity of flour, which you find by performing subtraction:
flour - sugar = (2 1/4) - (6/4) . . . . cups
Step 3: Use your knowledge of arithmetic.
(2 1/4) -(6/4) = 9/4 -6/4 = (9 -6)/4 = 3/4
Step 4: Answer the question that was asked.
The difference between the flour and sugar amounts is 3/4 cup.
Mrs. Crosland asked students to factor the expression 28x - 8. The students offered the answers shown
Carlos: 2(14x - 4)
Danny: 7(4x - 1)
Irene: 4(7x - 2)
Which student(s) offered answer(s) equivalent to the original expression?
Equivalent expression for the given expression is
4(7x-2)
Irene offered answer equivalent to the original expression
Given :
Mrs. Crosland asked students to factor the expression 28x - 8
The student are given some expression . To find correct expression , we need to factor the given expression
[tex]28x-8[/tex]
Both 28 and 8 are divisible by 4
Lets factor out 4 from the given expression.
When we factor out 4, then we divide each term by 4
[tex]28x-8\\4(\frac{28}{4} -\frac{8}{4} )\\4(7x-2)[/tex]
The students offered the answers shown
Carlos: 2(14x - 4)
Danny: 7(4x - 1)
Irene: 4(7x - 2)
so , from the answer we can say that Irene offered answer equivalent to the original expression

Write a system of equations for the problem.
9514 1404 393
Answer:
s + a = 2503s + 5a = 1050Step-by-step explanation:
Let s and a represent the numbers of student and adult tickets sold. The system of equations that can be written from the given information is ...
s + a = 250 . . . . . . total of tickets sold
3s +5a = 1050 . . . dollar value of tickets sold
_____
The solution is (s, a) = (100, 150). 100 student tickets and 150 adult tickets were sold.

what is the area of a trapezoid that has a height of 12 and it’s parallel sides measure 15 and 20? Show the steps in your work.
Answer:
Area of trapezoid = 210 unit²
Step-by-step explanation:
Given:
Height = 12 unit
Parallel side a = 15
Parallel side b = 20
Find:
Area of trapezoid
Computation:
Area of trapezoid = [(a+b)/2]h
Area of trapezoid = [(15+20)/2]12
Area of trapezoid = 210 unit²

If cost of 15 eggs is ? 75, then find out the cost of 4 dozens eggs.
Answer:
Each egg is $5 so 4 dozen(48) is $240
Step-by-step explanation:
the way to do this is 75/15= 5
and then you multiply 12 x 4 to get 48 eggs
and then multiply 48 x 5 to get $240
15:75
divide each by 5
3:15
(4 dozen is 48 -> 48/3 = 16)
multiply each by 16
48: 240
240Use the diagram to solve for x.
Answer:
8
Step-by-step explanation:
You know that the horizontal lines are parallel to each other.
The 8 and x is both on that diagonal right there. Since the horizontal lines are parallel, that means the angle of 8 should have the same angle as x.
