x = -0.441 and x = -2.359
Step-by-step explanation:
The given equation is :
[tex]2(5x+7)^2-13=33[/tex]
Adding 13 to both sides of the equation.
[tex]2(5x+7)^2-13+13=33+13\\\\2(5x+7)^2=46\\\\(5x+7)^2=23[/tex]
So,
[tex]5x+7=\sqrt{23}\\\\5x+7=\pm4.795\\\\5x=4.795-7, 5x=-4.795-7\\\\5x=-2.205, 5x = -11.795\\\\x=-0.441, x=-2.359[/tex]
So, the solution of the given equation is x = -0.441 and x = -2.359.

Answers
Answer:
There are 60 girls and 40 boys in the class.
Step-by-step explanation:
Given that the mean weight of 100 students in a certain class is 71kg, while the mean weight of boys is 65kg and that of girls is 75kg, to determine what is the number of boys and girls the following calculation must be performed:
1 x 75 + 0 x 65 + 75
0.9 x 75 + 0.1 x 65 = 74
0.8 x 75 + 0.2 x 65 = 73
0.7 x 75 + 0.3 x 65 = 72
0.6 x 75 + 0.4 x 65 = 71
Thus, there are 60 girls and 40 boys in the class.

y=-1/2x-1
Answers
Answer:
Step-by-step explanation:
Find the x and y intercept, and determine the slope.
X-intercept:
[tex]0=-\frac{1}{2}x-1\\1=-\frac{1}{2}x\\x=-2[/tex]
It crosses the x-axis at x = -2
Y-intercept:
[tex]y=-\frac{1}{2}(0)-1\\y=-1[/tex]
It crosses the y-axis at y = -1
Slope:
y = mx + b
m = slope = -1/2
The graph of the linear equation y = -(1/2)x - 1 is plotted.
Given data:
To graph the equation y = -1/2x - 1, use the slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.
So, the slope is -1/2, and the y-intercept is -1.
To plot the graph, follow these steps:
Plot the y-intercept:
Start by plotting the point (0, -1), which represents the y-intercept.
Use the slope to find another point: Since the slope is -1/2, use the rise and run method. From the y-intercept point (0, -1), move down 1 unit (negative 1) and then move to the right 2 units. This gives another point on the line, which is (2, -2).
Hence, the resulting graph should be a straight line sloping downwards from left to right and is plotted below.

£2,300 is invested for 4 years at 5% per year simple interest work out the total interest
Answers
Answer:
£460
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 2300 × 0.05 × 4 = 460
I = £ 460.00
The simple interest accumulated
on a principal of £ 2,300.00
at a rate of 5% per year
for 4 years is £ 460.00.
