4x-3y=-1
4x+y=11
Step-by-step explanation:
4x-3y=-1
4x+y=11
[tex]4x = - 1 + 3y \\ x = \frac{ - 1 + 3y}{4} [/tex]
[tex] - 1 + 3y = 11 - y \\ 3y + y = 11 + 1 \\ 4y = 12 \\ y = 3[/tex]
[tex]x = \frac{ - 1 + 3 \times 3}{4} \\ x = \frac{ - 1 + 9}{4} \\ x = \frac{8}{4} = 2[/tex]

The measure of central angle XYZ is StartFraction 3 pi Over 4 EndFraction radians. What is the area of the shaded sector? 32Pi units squared 85 96Pi units squared 256Pi units squared
Answer:
96π units²
Step-by-step explanation:
Find the diagram attached
Area of a sector is expressed as;
Area of a sector = θ/2π * πr²
Given
θ = 3π/4
r = 16
Substitute into the formula
area of the sector = (3π/4)/2π * π(16)²
area of the sector = 3π/8π * 256π
area of the sector = 3/8 * 256π
area of the sector = 3 * 32π
area of the sector =96π units²
Answer:
96π units²

If the simple interest on $6,000 for 3 years is $1,620, then what is the interest rate?
Answer:
Interest rate: 9%
Step-by-step explanation:
Using the simple interest formula: A=P(1+rt)
A=Final amount
P=Principal amount
r=rate
t=time (years)
We just need to put in the information we have from the question and solve for r.
7,620=6000(1+r3)
7,620/6000=1+r3
1.27=1+r3
0.27=r3
r=0.09
r=9%

Answer:
S(x) = x⁴ + 2x³ + 15Step-by-step explanation:
The function S(x) has shifted up (vertical translation) by 10 units as seen on the graph
The transformation rule is:
S(x) → S(x) + 10Therefore new equation is:
S(x) = x⁴ + 2x³ + 15Determine the GCF of the coefficients.
This is the ____ integer that divides into each coefficient.
(A) greatest
(B) least
Determine the GCF of the variable parts.
For each variable common to all the terms, choose the power of the variable with the __ exponent.
(A) greatest
(B) least
A is correct = greatest.

What are Linear Pair of Angles?Linear pair of angles are the pair of angles formed when two lines are intersected at a point forming on a line.
Sum of the measures of angles of linear pair is supplementary.
Linear pair of angles are formed on a line.
So we have the pair of angles given, 12x + 19 and 22x - 9 are a linear pair of angles.
They are supplementary angles.
(12x + 19) + (22x - 9) = 180
12x + 22x + 19 - 9 = 180
34x + 10 = 180
34x = 180 - 10
34x = 170
x = 170 / 34
x = 5
Hence the value of x is 5.

Write an equation in slope-intercept form of the line that passes through (2,-2) and slope of -4
Answer:
y = - 4x + 6Step-by-step explanation:
Starting with the point-slope form of the equation {y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope}:
m = -4
(2, -2) ⇒ x₀ = 2, y₀ = -2
So, the point-slope form of the equation:
y + 2 = -4(x - 2)
Therefore:
y + 2 = - 4x + 8 {subtract 2 from both sides}
y = - 4x + 6 ← the slope-intercept form of the equation

Jermaine and Josh observed an anthill for their science project. They observed that an ant moved 45.0 millimeters (mm) in 85.0 seconds (s). How fast was the ant moving?
Answer:
Velocity =displacement/time
Distance covered is 45mm which is 0.045m or 0.45cm but the displacement is very small so use mm instead. Time taken (t) to cover the distance is 85s. V=45/85
V=0.53mm/s
