find the equation of a line whose gradient is -¾ and y intercept is 2
Answer:y =-3x/4+2
Step-by-step explanation:
Slope= -3/4
The line is passing through (0,2).
y-2=(x-0)*-3/4
or
y =-3x/4+2

4 less than a number n is -15.
Equation:
Solution n=
Answer:
n = - 11
Step-by-step explanation:
4 less than a number n is
n - 4 = - 15 ( add 4 to both sides )
n = - 11
write an explicit and recursive formula for the sequence -4, -6, -8, 10
Answer:
Each term is 2 greater than the term before it. Thus for any given term, an, our equation is:
an=2n
We can write this in a form closer to standard, by noting that a1=2, so we can make it dependent on a1..
an=a1+2(n−1)=2+2(n−1)
Which of the following represents "four times the square of a number is thirty-six"?
(4x) 2 = 36
4 2x = 36
4x 2 = 36
Answer:
the answer will be 4x²...last option
Answer:
Answer is 4x² = 36
Step-by-step explanation:
Let that number be x:
[tex]4 \times x {}^{2} = 36 \\ {4x}^{2} = 36[/tex]
further more:
[tex] {x}^{2} = \frac{36}{4} [/tex]
take a square root:
[tex] \sqrt{ {x}^{2} } = \sqrt{ \frac{36}{4} } \\ \\ x = \frac{ \sqrt{36} }{ \sqrt{4} } \\ \\ x = \frac{6}{2} \\ \\ x = 3[/tex]

Using pythagorean theorem
[tex]\\ \sf\longmapsto x^2=11^2+11^2[/tex]
[tex]\\ \sf\longmapsto x^2=121+121[/tex]
[tex]\\ \sf\longmapsto x^2=242[/tex]
[tex]\\ \sf\longmapsto x=\sqrt{242}[/tex]
[tex]\\ \sf\longmapsto x=15.4[/tex]
Step-by-step explanation:
Use the pythagorean theorem
[tex]a {}^{2} + b {}^{2} = c {}^{2} [/tex]
[tex]11 {}^{2} + 11 {}^{2} = c {}^{2} [/tex]
[tex]121 + 121 = c {}^{2} [/tex]
[tex]c = \sqrt{242} = 2 \sqrt{11} [/tex]

Answer:
the play area is a circle with radius = 12
Step-by-step explanation:
Circle area = A= π r²
r = radius
A = 144 π = 452.39
Diameter = 2r
= 24
circumference = C = 2π r
= 24 π = 75.4
Q2)
Area = π r²
r = 15
r²= 225
area = 706.5

To solve the equation, Antwan uses the distributive property, combines like terms, then uses the addition and subtraction properties of equality to isolate the variable term on one side of the equation and the constant term on the other side. What are the possible values of the constant after Antwan has completed these steps?

If the remaining books are of Mathematics, what is the fraction of those books?
1/15 b) 4/15 c) 2/15 d) 7/15
Answer:
c) 2/15
Step-by-step explanation:
LA= 2/3 = 10/15
S=1/5 = 3/15
15/15 - 13/15 = 2/15
Math books= 2/15
You invested $20,000 in two accounts paying 7% and 8% annual interest, respectively. If the total interest earned for the year was $1530, how much was invested at each rate?
Answer:
$7,000 at 7%; $13,000 at 8%
Step-by-step explanation
x: the amount invested at 7%
y: the amount invested at 8%
x + y = 20,000
7%.x + 8%.y = 1,530
⇒ x =7,000
y = 13,000

4x/x^2-8x+7+5x/x^2-10x+7
Answer:
simplified: -18x + 14 + [tex]\frac{9}{x}[/tex]
Step-by-step explanation:
-8 < 2x - 4 < 8 how do I solve this
-8 < 2x-4 < 8
Add 4 to all sides:
-8 + 4 < 2x -4 + 4 < 8 + 4
Simplify :
-4 < 2x < 12
Divide all sides by 2:
-4/2 < 2x/2 < 12/2
Simplify to get the answer:
-2 < x < 6
