Answer:
y =1, 1.5, 2, 2.5, 3
Step-by-step explanation:
Plug in the values of x into the equation for y.
For example when x is 0, plug in 0 into the equation
0.5x + 1 = y
0.5(0) + 1 = 1
So, y = 1
To find the other values of y, plug in the designated value of x into the equation.

Jasmine and Kelly each bought a pizza. The pizzas are the same size.
Jasmine cut her pizza into 12 slices.
Kelly cut her pizza into 6 slices, and ate 2 slices.
Together, Jasmine and Kelly ate of one pizza.
How much of the pizza did Jasmine eat?
Answer:
4/6 of a pizza.
Step-by-step explanation:
We know that:
Both pizzas are of the same size.
Jasmine cut her's into 12 slices.
Kelly cut her's into 6 slices, and ate 2 slices, then Kelly ate 2/6 of a pizza.
Jasmine ate X of a pizza, and we know that between them ate a total of 1 pizza.
This means that:
X of a pizza + 2/6 of a pizza = 1 pizza
X + 2/6 = 1
X = 1 - 2/6
X = 6/6 - 2/6 = 4/6
Jasmine ate 4/6 of a pizza, knowing that she cut her's into 12 slices, this would mean that she ate 8/12 of a pizza, or 8 slices.
Please solve! It's really easy (I think).

y=x+4
y=3x−1
9514 1404 393
Answer:
(x, y) = (2.5, 6.5)
Step-by-step explanation:
I find it easier just to solve the system of equations:
x + 4 = 3x - 1
5 = 2x
x = 5/2 = 2.5
y = x+4 = 6.5
(x, y) = (2.5, 6.5)
__
Additional comments
The first equation has a positive y-intercept and a positive slope, so makes a triangle with the axes in the 2nd quadrant.
The second equation has a negative y-intercept and a (more) positive slope, so makes a triangle with the axes in the 4th quadrant. The slope is greater for this line, so the lines will intersect in the 1st quadrant. Without more effort, the best estimate at this point is that x and y are both positive and y > 4.
how do I solve this?
Answer:
[tex] x = \frac{3}{2} + \frac{ \sqrt{5} }{2} ; \: \: x = \frac{3}{2} - \frac{ \sqrt{5} }{2} [/tex]
Step-by-step explanation:
[tex]1 + \frac{1}{ {x}^{2} } = \frac{3}{x} \\ \\ \frac{ {x}^{2} + 1 }{ {x}^{2} } = \frac{3}{x} \\ \\ {x}^{2} + 1 = \frac{3 {x}^{2} }{x} \\ \\ {x}^{2} + 1 = 3x \\ \\ {x}^{2} - 3x + 1 = 0 \\ equating \: it \: with \\ a {x}^{2} + bx + c = 0 \\ a = 1 \\ b = - 3 \\ c = 1 \\ \\ x = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac} }{2a} \\ \\ x = \frac{ - ( - 3) \pm \sqrt{ {( - 3)}^{2} - 4 \times 1 \times 1} }{2 \times 1} \\ \\ x = \frac{ 3 \pm \sqrt{ {9 - 4}} }{2} \\ \\ x = \frac{ 3 \pm \sqrt{ {5}} }{2} \\ \\ x = \frac{3}{2} + \frac{ \sqrt{5} }{2} ; \: \: x = \frac{3}{2} - \frac{ \sqrt{5} }{2} [/tex]

two percent of a product are defective. if a lot of 100 items are ordered what's the probability that there are no defective item? what's the probability that there are at least two defective items?
Answer:
P(X ≥ 2) = 0.5967
Step-by-step explanation:
Using binomial probability distribution formula;
P(X = k) = C(n, k) × p^(k) × (1 - p)^(n - k)
two percent of a product are defective. Thus; p = 0.02
a lot of 100 items are ordered. Thus, n = 100
Probability that there are no defective items is;
P(X = 0) = C(100, 0) × 0.02^(0) × (1 - 0.02)^(100 - 0)
P(X = 0) = 0.98^(100) = 0.1326
the probability that there are at least two defective items will be;
P(X ≥ 2) = 1 - P(X < 2)
Now,
P(X < 2) = P(X = 0) + P(X = 1)
P(X = 1) = C(100, 1) × 0.02^(1) × (1 - 0.02)^(100 - 1)
P(X = 1) = 100 × 0.02 × 0.98^(99) = 0.2707
Thus;
P(X < 2) = 0.1326 + 0.2707
P(X < 2) = 0.4033
P(X ≥ 2) = 1 - 0.4033
P(X ≥ 2) = 0.5967
The price of apples can be determined by the equation P=0.23n, where P is the price and n is the number of apples. What is the constant of proportionality (unit rate)
Answer:
The constant of proportionality(Unit rate) is 0.23
Step-by-step explanation:
Given equation is:
[tex]P = 0.23n[/tex]
Here
P is the price and n is the number of apples
The price is usually directly proportional to quantity so the relationship can be written as:
P ∝ n
Removing the proportionality symbol, we get
P = kn
Comparing the given equation with this equation we get
k = 0.23
Hence,
The constant of proportionality(Unit rate) is 0.23

Step-by-step explanation:
sqrt(x + 2) - 15 = -3
sqrt(x + 2) = 12 (add 15 to both sides)
x + 2 = 12² = 144 (square both sides)
x = 142.
Answer:
x = 142
Step-by-step explanation:
√x+2 - 15 = -3 (Given)
√x+2 = 12 (Add 15 on both sides)
x + 2 = 144 (Square both sides to get rid of the radical)
x = 142 (Subtract 2 on both sides)
-4 -(-12)= 12 + (-4) true or false

Stephanie and Jill share a reward of $65 in a ratio of 1 : 4. How much does Stephanie get?
Answer:
The answer is 52$
Step-by-step explanation:
the ratio converted in fraction is 1/5 by doing 4+1,
now you do 1/5 of 65 total dollars,
so you do 1/5 of 65,
=65/5
=13
jill will get 13$. but the question is asking for how much money did stephanie get. So now we do 13*4 which is 52$.
So stephanie gets 52$

Answer:
[tex]-3\cdot x + 5\cdot y = 6[/tex], [tex]6\cdot x -10\cdot y = 14[/tex] is inconsistent.
Step-by-step explanation:
Two linear equations are inconsistent when each group of coefficients associated with each variable have the same multiple and independent coefficients are different and have the same multiple. Since, the set of variables is [tex](x,y)[/tex], then the following condition must be observed:
[tex]k_{x} = k_{y} \ne k_{c}[/tex] (1)
[tex]k_{x} = \frac{a_{x}}{b_{x}}[/tex] (2)
[tex]k_{y} = \frac{a_{y}}{b_{y}}[/tex] (3)
[tex]k_{c} = \frac{a_{c}}{b_{c}}[/tex] (4)
Now we proceed to check each option:
Option 1: [tex]x + 4\cdot y = 20[/tex], [tex]2\cdot x - y = 7[/tex]
([tex]a_{x} = 1[/tex], [tex]a_{y} = 4[/tex], [tex]b_{x} = 2[/tex], [tex]b_{y} = -1[/tex])
[tex]k_{x} = \frac{1}{2}[/tex], [tex]k_{y} = -4[/tex] (This system is not inconsistent)
Option 2: [tex]3\cdot x + 2\cdot y = -2[/tex], [tex]4\cdot x -y = -2[/tex]
([tex]a_{x} = 3[/tex], [tex]a_{y} = 2[/tex], [tex]b_{x} = 4[/tex], [tex]b_{y} = -1[/tex])
[tex]k_{x} = \frac{3}{4}[/tex], [tex]k_{y} = -2[/tex] (This system is not inconsistent)
Option 3: [tex]8\cdot x + 4\cdot y = 16[/tex], [tex]4\cdot x - 2\cdot y = 6[/tex]
([tex]a_{x} = 8[/tex], [tex]a_{y} = 4[/tex], [tex]b_{x} = 4[/tex], [tex]b_{y} = -2[/tex])
[tex]k_{x} = 2[/tex], [tex]k_{y} = -2[/tex] (This system is not inconsistent)
Option 4: [tex]-3\cdot x + 5\cdot y = 6[/tex], [tex]6\cdot x -10\cdot y = 14[/tex]
([tex]a_{x} = -3[/tex], [tex]a_{y} = 5[/tex], [tex]b_{x} = 6[/tex], [tex]b_{y} = -10[/tex])
[tex]k_{x} =-\frac{3}{5}[/tex], [tex]k_{y} = -\frac{3}{5}[/tex] (This system may be inconsistent)
([tex]a_{c} = 6[/tex], [tex]b_{c} = 14[/tex])
[tex]k_{c} = \frac{3}{7}[/tex] (This system is inconsistent)
The slope of the line is m=3/4. One point is (x, 2) and (3,-4)
Find X
Please helppppp
Answer:
x = 11
Step-by-step explanation:
Given that,
The slope of the line, m = 3/4
First point = (x,2)
Another point = (3,-4)
We need to find the value of x.
The slope of a line is given by the formula as follows :
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Put x₁ = x, y₁ = 2, x₂ = 3, y₂ =-4 and m = 3/4
Put all the values,
[tex]\dfrac{3}{4}=\dfrac{-4-2}{3-x}\\\\3(3-x)=4(-6)\\\\9-3x=-24\\\\9+24=3x\\\\33=3x\\\\x=11[/tex]
So, the value of x is 11.
Which statements about the expression 5y + 9 are true? There are multiple answers.
a. The number 5 in the expression is a constant.
b. The expression has one variable term.
c. The variable in the expression is y.
d. The number 5 is not a coefficient in the expression.
e. The expression has three terms.
Answer:
(b) and (c).
Step-by-step explanation:
The given expression is : 5y+9
In this equation, y is only variable. 5 times of y is added to 9.
Option (a) is incorrect as 9 is constant instead of 5.
Option (b) is correct.
Option (c) is correct as y is only variable here.
Option (d) is incorrect as 5 is coefficient of y only not of whole expression.
Option (d) is incorrect as there are 2 terms i.e 5y and 9.
Hence, correct options are : (b) and (c).
