Find the value of f(-1) for the function f(x)=4x + 10 *
Solve x ^ 2 + 10x = -21.
x = 7 and x = 3
x = -7 and x = -3
x = - 7 and x = 3
x = 7 and x = -3
Answer:
X = -7, -3
(AKA B)
Answer:
x= -7 and x= -3
Step-by-step explanation:
x^2 + 10x = -21
= X^2 + 10x + 21 (Bring the -21 to the other side to make it positive)
factor the equation...
= (x+7)(x+3)
x= -7 and x= -3

What are linear equations?Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.
Given here: 2x+8y , putting x=-5 and y=6 we get
2x+8y= 2×-5+8×6
=-10+48
=38

Saul made some extra money last year from a part-time job. He invested part of the money at 2% with four times as much invested at 3.25%. He made a total of $150.00 in interest. How much was invested at 3.25%?
Answer:
$4000
Step-by-step explanation:
Given that :
Total interest earned = $150
Let amount invested (p) at 2% = x
Amount invested (p) at 3.25% = 4x
Interest = principal * rate * time
At 2%:
(x * 0.02 * 1 ) + (4x * 0.0325 * 1) = 150
0.02x + 0.13x = 150
0.15x = 150
x = 150 / 0.15
x = 1000
Hence,
Amount invested at 2% = x = 1000
Amount invested at 3.25% = 4x = 4(1000) = 4000

A, B & C form a triangle where ∠ BAC = 90°.
AB = 9.4 mm and CA = 8.9 mm.
Find the length of BC, giving your answer rounded to 1 DP.
BC = mm
Answer:
12.9
Step-by-step explanation:
To solve this, you need to use the Pythagorean Theorem: a² + b² = c²
Substituting the numbers into the formula:
(9.4)² + (8.9)² = c²
(88.36) + (79.21) = c²
167.57 = c²
12.9 ≈ c

What is absolute value of a number?
The absolute value of a number is the magnitude of number. Absolute value describes the distance from zero that a number is on the number line, without considering direction.
We have the following expression -
|- 5| + |3|
For a number [x], such that [x] < 0, the absolute value would be -
v[a] = - x
and for [x] > 0
v[a] = x
So, for x = |- 5| + |3| , the equivalent expression would be -
5 + 3
8
Therefore, the following expression → |- 5| + |3| is equivalent to 8.
