Find the gradient and intercept on the x and y axes of the straight line with the following equation.
y + 5x = 13
Answer:
gradient is 5
Step-by-step explanation:
x intercept, replace y with 0
y +5x= 13
0+ 5x =13
0 - 13= -5x
-13= -5x
-13/-5 = -5x/-5
x = 13/5
y intercept, replace x with 0
y+5x=13
y+5(0)=13
y+0=13
y =13
Rectangle PROM has a perimeter of 42 inches, and OR = 8 inches. What is the area of the rectangle PROM?
Answer:
104 in²
Step-by-step explanation:
If OR = 8 then 8 x 2 = 16
PM= (42-16)/2=13
Therefore area = 8 x 13 = 104 in²
To check the perimeter is right:
2(8+13) = 42
the length of a rectangular field three times of it's breath.if the area of the field is 675 m2, find the perimeter
with full solution
L/W = 3/1 or L = 3*W
A = L*W = (3*W)*W = 3*W^2 = 675 m^2
W^2 = (675 m^2)/3 = 225 m^2
W = sqrt(225 m^2) = 15 m
L = 3*W = 3*(15 m) = 45 m
Roger paid $27.50 for a sweatshirt. This amount includes a sales tax of 10%. What was the cost of the sweatshirt before tax?
Answer:
$ 24.75
Step-by-step explanation:
10/100 = x/27.50 (10% is what of 27.50) (%/100 = is/of)
(27.50)(10)/100 (cross multiply)
= $2.75 (tax)
27.50 - 2.75 = $ 24.75
What is the x intercept of this quadratic/parabola?
Answer:
-3, 1
Step-by-step explanation:
There are actually 2 x-intercepts of the parabola. You can find them simply by looking along the x-axis and seeing where the lines of the parabola touch the axis, so -3 and 1.
Hope this helps :)
Answer:
1 and -3
Step-by-step explanation:
At x-intercept y = 0
So, parabola intersect x-axis at two places (1 , 0) and (-3 , 0)
X-intercepts are 1 and -3

You should find the area under the curve. Which will give you multiple shapes. That are 3 triangles and one rectangle. Then use the Rule of the area of the triangle which is 1/2 × base × height then lastly. When you find the area for each shape you then find the sum of all the distance to give you the full area under the curve.

Subtract. 3- (-5) - (-2) Plot the solution on the number line.
Answer:
10. put a dot on the number 10
Step-by-step explanation:
3-(-5)-(-2)
when subtracting negatives, you actually end up adding
so
3+5+2=10
3 - (5) - (-2) = 10.
The solution will be positive 10 on the line.
use a double angle formula to rewrite the expression. 16sin (x) cos (x)
Answer:
8sin(2x).
Step-by-step explanation:
2sin(x)cos(x) = sin(2x)
So 16sin(x)cos(x)
= 8* 2sin(x)cos(x)
= 8sin(2x).
(7g - 6) - (-3n – 4) =
Answer:
7g + 3n - 2
Step-by-step explanation:
when you subtract you 'add the opposite'; subtracting a negative is the same as adding a positive
for example, using the above statement we can rewrite the problem as:
7g - 6 + 3n + 4
we can combine -6 and 4 to get -2
7g + 3n - 2 or 7g + 3n + (-2)

a) 15.8 cm
b) 14.2 cm
c) 12 cm
d) 19.2 cm
[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
Please refer to the attached picture for the answers with steps included.
NOTE :-
The sides of a rhombus are equal to each other.The point of intersection of the diagonals (marked as O in the figure) forms 90° angles (which is why we used the pythagoras property to solve the question).Since 0 is the point of intersection, it's also the midpoint of the diagonals. (So, BO = ½ × BD & AO = ½ AC -- we used this to solve the question).__________________

A cheetah runs 296 feet in 4 seconds. How far could a cheetah run in 10
seconds at this rate?
Answer:
740 feet
Step-by-step explanation:
The speed of the cheetah is 74 feet per second:
speed = distance ÷ time
= 296 ÷ 4 = 74 feet per second
In 10 seconds:
distance = speed × time
= 74 × 10
= 740 feet
Answer:
740 Feet
Step-by-step explanation:
Given: 296 ft= 4 sec
To Find: 10 sec = [tex]\left[?}\right][/tex] ft
First we need to Find How many feet are in 1 second.
To find that,
Do 296 divided by 4
=
74
So 1 second = 74 Feet.
Then 74 ft Times 10 second
Which gives you
740 Feet.
Therefore, at 10 second rate gives you 740 Feet.

The simplified expression is 7x- 2.
What is Expression?A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.Given:
−4x−2y+6 from 3x−2y+4.
So, subtraction will be as follows
3x - 2y + 4-( -4x -2y + 6 )
or, 3x - 2y + 4 + 4x + 2y -6
or, 7x - 2
Hence, the simplified expression is 7x- 2.
