Answer:
Well to solve this I’m gonna use substitution
So
2x-3y=-14
5x+9y=14
I‘m gonna isolate ”x” on the first equation
So it’ll be
2x-3y=-14
2x=-14+3y
x=-7+1.5y
X is -7+1.5y
Now you can subsitute into other equations to find what Y is worth
So lets use the second equation
5(-1+1.5y) + 9y = 14
Now solve for y which is -2
If you subsitute Y back in an equation you’d get -4 for x
So y = -2
and X= -4

Here is me work:
There are fewer than 30 students in the A-level mathematics class. One half of them
play the piano, one quarter play hockey and one seventh are in the school play.
How many of the students play hockey?
The number of students that play hockey is 7
The proportion is given as:
[tex]Piano =\frac 12[/tex]
[tex]Hockey =\frac 14[/tex]
[tex]School\ Play =\frac 17[/tex]
The total number of students must be a multiple of 2, 4 and 7 less than 30;
The only multiple of 2, 4 and 7 less than 30 is 28.
The number of students that play hockey is the product of 28 and the proportion that plays hockey.
So, we have:
[tex]Hockey =\frac 14 \times 28\\[/tex]
Multiply
[tex]Hockey =7[/tex]
Hence, 7 students play hockey

Analyze the student’s work. Is the answer correct? Explain. No, the student should have added 3 4 to get the total number of sections, and used the fraction Three-sevenths instead of Three-fourths. No, the student should have subtracted 2 from â€"6 to find the distance. No, the student should have added 2 at the end to add to the starting point. Yes, the student’s answer is correct.
The student's work is incorrect, and the reason is (a) No, the student should have added 3 4 to get the total number of sections, and used the fraction 3/7 instead of 3/5
From the complete question, the given parameters are:
[tex]Ratio =3 : 4[/tex] ---- the ratio
[tex]A = -6[/tex]
[tex]B = 2[/tex]
The student's steps are as follows:
[tex]C = \frac 34 (2 -(-6)) + (-6)[/tex]
[tex]C = \frac 34 (8) + (-6)[/tex]
[tex]C = 6 -6[/tex]
[tex]C = 0[/tex]
To determine the position of point C from the given ratio, we make use of the following quotient;
[tex]Position = \frac 3{3 + 4}[/tex]
[tex]Position = \frac 37[/tex]
This means that, the student ought to add 3 and 7, to get the total number of section.
Hence, the student's work is incorrect, and the reason is (a)

Answer:
y = 6
Step-by-step explanation:
A line with a slope of zero is a horizontal line parallel to the x- axis with equation
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (- 5, 6 ) with y- coordinate 6 , then
y = 6 ← equation of line

Find y such that the slope between (2, y) and (5, -3) is 7.
Answer:
y= -24
Step-by-step explanation:
since the slope is 7 the value of y should decrease as the value of x decreases. and since you went back 3 on the x, you should go down 21 on the y resulting in -3-21 which is -24
A line passes through the points (-4,1) and (-3,3). This line can be modeled by the equation y = mx + b.
Complete the table to determine the values of m and b.
Answer:
m= 2
b=9
Step-by-step explanation:
-4, 1 -3,3
put it into y2-x2 divided by y1-x1
y2= 3
x2= 1
y1= -3
x1=-4
3-1 divided by -4--3= 2/1 =2x
get one of the points either -4,1 or -3,3
If you use -4,1 -4=x 1=y
put it into y=mx+b and you get 1= -4(2)+b simplify
1=-8+b add 8 to other side b=9

Step-by-step explanation:
Discount 25% of $24.60 is :
(25/100) x 24.6 = 6.15
$24.60 - 6.15 = $18.45
Tax 4.5% of $24.60 is :
(4.5/100) x 24.6 = 1.107 approx. 1.11
Amount to be paid = $18.45 + $1.11 = $19.56

A quadrilateral has two angles that measure 63° and 154°. The other two angles are in a ratio of 4:9. What are the measures of those two angles?
Answer:
44° and 99°
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Subtract the 2 given angles from 360° to find the remaining sum
360° - (63 + 154)° = 360° - 217° = 143°
The 2 angles which sum to 143° are in the ratio 4 : 9
sum the parts of the ratio, 4 + 9 = 13 parts , then
143° ÷ 13 = 11° ← value of 1 part of the ratio, so
4 parts = 4 × 11° = 44°
9 parts = 9 × 11° = 99°
The other 2 angles are 44° and 99°

The price of petrol increased by 8% to Rs 540 per litre. Find the old price.
Answer:
The original price is Rs. 50
Step-by-step explanation:
Let the original price be Rs.x
x+8% of x=54
x+(8/100)*x=54
x+8x/100=54
(100x+8x)/100=54
108x/100=54
x=54* 100/108
x=50.
The original price is Rs. 50
Answer:
Rs 500 per literStep-by-step explanation:
Let the initial price be x.
We have:
x + 8% of x = 540Rewrite it as below and solve for x:
x + 0.08x = 5401.08x = 540x = 540/1.08x = 500Which describes how triangle D was transformed to result in similar triangle D'?
