Answer:
(2,7)
Step-by-step explanation:
Variable Definitions:
x=
x=
\,\,\text{the number of apples}
the number of apples
y=
y=
\,\,\text{the number of bananas}
the number of bananas
\text{\textquotedblleft a minimum of 7 items"}\rightarrow \text{7 or more items}
“a minimum of 7 items"→7 or more items
Use a \ge≥ symbol
Therefore the total number of apples and bananas, x+yx+y, must be greater than or equal to 7:7:
x+y\ge 7
x+y≥7
\text{\textquotedblleft \$8 to spend"}\rightarrow \text{can spend \$8 or less}
“$8 to spend"→can spend $8 or less
Use a \le≤ symbol
One apple costs $2, so xx apples cost 2x.2x. One banana costs $0.50, so yy bananas cost 0.50y.0.50y. The total 2x+0.50y2x+0.50y must be less than or equal to \$8:$8:
2x+0.50y\le 8
2x+0.50y≤8
\text{Solve each inequality for }y\text{:}
Solve each inequality for y:
\begin{aligned}x+y\ge 7\hspace{30px}& 2x+0.50y\le 8 \\[0.8em] y\ge 7-x \hspace{30px}& 0.50y\le 8-2x \\[0.8em] \hspace{30px}& y\le \frac{8-2x}{0.50} \\[0.8em] & y\le 16-4x\end{aligned}
x+y≥7
y≥7−x
2x+0.50y≤8
0.50y≤8−2x
y≤
0.50
8−2x
y≤16−4x
Graph y\ge 7-xy≥7−x by shading up and graph y\le 16-4xy≤16−4x by shading down:
0
the number of apples
the number of bananas
x
y
0
the number of apples
the number of bananas
(2, 7)
Since the point (2, 7(2,7) is inside the double shaded region, one possible solution to the system of inequalities would be:
Zoey could buy 2 apples and 7 bananas.

Compare rates of change.
The equation below can be used to find the length of a foot or forearm when you know one or the other.
(length of the foot) = 0.860 • (length of the forearm) + 3.302
If you let y = length of the foot and x = length of the forearm, this equation can be simplified to
y = 0.860x + 3.302.
Using this equation, how long would the foot of a person be if his forearm was 17 inches long?
What is the rate of change of the equation from Part A?
Compare the equation from Part A to your data. Are they the same? Which has a greater rate of change? Why do you think the values are different?
Is the relation in your data a function? Why or why not? Could the equation in Part A represent a function? Why or why not? Explain your answer.
Answer:
Step-by-step explanation:
y=0.860x17+3.302
foot is 17.992 inches long
Unfortunately, I don't have access to your data so i can't give a solid answer. However, I can tell you that if your coefficeint (number before x) is greater than 0.86, you have a greater rate of change. If its smaller, its a lower rate of change.

x²-49
x²-9
x²-16
Answer:
Step-by-step explanation:
x2 - 49
Both are squares so
Square root (x2) - Square root (49)
= x - 7
The other two answers are x - 3 and x - 4
Answer:
Use the formula (x-a)(x+a)=x^2 - a^2
so what is the square root of 49, 9, and 16? By finding the square root you get a, and you can just plug it into the formula. For example the first one, 7 is the square root of 49. So, (x-7)(x+7)

(5x +40x +
+ 40x+31) = (x+7)
Answer:
Step-by-step explanation:
5x + 40x + 40x + 31 = x + 7
85x + 31 = x + 7
Bringing like terms on one side
85x - x = 7 - 31
84x = - 24
x = - 24/84 = 2/7

What is the measure of angle c?
97°
a
du
b
54°
HELP
Answer:
∠ c = 29°
Step-by-step explanation:
∠ b = 97° ( vertical angles are congruent )
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
∠ c + 54° + 97° = 180°
∠ c + 151° = 180° ( subtract 151° from both sides )
∠ c = 29°

Both roots of x^2 + Nx + 144 are equal to each other. Find all the possible values of N.
Answer:
N=+24,-24
Step-by-step explanation:
Well this is a quadratic equation and we can make further deductions using it's discriminant
b²-4ac=0
N²-4(1×144)=0
N²-576=0
N²=576
N=√576
N=+24,-24
The possible values of N are +24, and -24 if both roots of x² + Nx + 144 are equal to each other.
What is a quadratic equation?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
It is given that:
The quadratic equation is:
x² + Nx + 144 = 0
Discriminant will be zero:
D = 0
b²-4ac=0
N²-4(1×144)=0
N²=576
N=√576
N=+24,-24
Thus, the possible values of N are +24, and -24 if both roots of x² + Nx + 144 are equal to each other.

What is the equation of a line that is parallel to -x + 3y = 6 and passes through the point (3, 5)?
Answer:
y = 1/3x + 4
Step-by-step explanation:
Make it into slope intercept form
3y = x + 6
y = 1/3x + 2
parallel = same slope
y = 1/3x + b, plug in (3,5)
5 = 1/3(3) + b, b = 4
y = 1/3x + 4

As part of your retirement, you wish to generate $2,000 monthly payments for a 15-year period. The annual interest rate is 5%. What minimum amount is necessary to fund these payments?
Answer:
$962.0
Step-by-step explanation:
The formula for amount is ;
[tex]A=P(1+\frac{r}n} )^{nt}[/tex]
where
A= amount at the end of the period= $2000
P=minimum amount necessary to fund the payments
r= annual interest rate = 5% = 0.05
n= number of compounding per year , 1
t= time period = 15 years
Applying the values to the formula as;
[tex]2000=P(1+\frac{0.05}{1} )^{1*15} \\\\\\2000=P(1.05)^{15} \\\\\\2000/2.079=P\\\\\\962.0=P[/tex]

Answer:
So 180-94 =86 so then it becomes 60°, 86°, and 2x so you would then add 60 and 86 together and get 146 and 180 - 146 is 34 then divide by two and you get 17 so x=17°
Step-by-step explanation:
Sorry if that’s confusing
Answer:
x = 17
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
94° is an exterior angle of the triangle, thus
2x + 60 = 94 ( subtract 60 from both sides )
2x = 34 ( divide both sides by 2 )
x = 17
Find the area of a circle having circumference 176 cm...Pls answer this question...
Answer:
area of circle = 2464 cm²
Step-by-step explanation:
circumference = 176 cm
formula of circumference = 2πr
2πr = 176 cm
2 × 22/7 × r = 176 cm
44/7 ×r = 176 cm
r = 176 ÷ (44/7)
r = 176 × 7/44
r = 28 cm
area of circle
= πr²
= 22/7 × 28²
= 22/7 × 784
= 2464 cm²
