Answer:
the answer to the equation is x= -3
i have absolutely no idea pls help <3 geometry/algebra
Answer:
the third option!!
in order for two equations to be parallel they need to have the same slope.
The equation that Mr. Foringer graphed has a slope of 3/4, so we need to pick the one that has the same slope.
The third option has the same slope, so it's the solution to this problem!

How many degrees has (triangle)ABC been rotated counterclockwise about the origin?
Answer:
180°
Step-by-step explanation:
180
The total number of degrees in which has the triangle ABC been rotated counterclockwise about the origin is 180 degrees.
What is the rotation of the figure?The transformation of a figure around a point, either clockwise or counterclockwise, is called rotation. A figure's coordinate point changes when it rotates.
About the origin, the triangle ABC has been rotated. The new triangle A'B'C' is created as a result. In the graph below,
The vertex B' points have the same but negative coordinates,
The vertex of B of the original figure points on the same line.
The coordinate point of B is (5,8).
The coordinate points of B' is (-8,-5).
The same will goes for the A and C points of the triangle
Thus the change in coordinate point after the rotation is,
coordinates of B = (5,8)
coordinates of B' = (-5, -8)
The same will follow with A and C
This is the rotation rule of 180 degrees counterclockwise.
Therefore, The triangle ABC has been rotated 180 degrees counterclockwise in all with respect to the origin.

A bicycle is originally priced at $80 the store owner gives a discount in the bicycle is know priced at $60 enter the percent markdown for the cost of the bicycle
Answer:
25%
Step-by-step explanation:
Since we know that the markdown is $20 by subtracting 80-60 , we find out what percent of 20 is 80. To do that you do 20/80, which is 0.25, or 25 percent.

A major credit card company is investigating whether the distribution of the number of credit cards used by its customers has changed from last year to this year. Customers are classified as using 1 card, 2 cards, or more than 2 cards. The company conducts a chi-square goodness-of-fit test to investigate whether there is a change in the distribution of number of cards used from last year to this year. The value of the chi-square test statistic was
Answer:
C) If the null hypothesis were true, there is a 2 percent chance of obtaining a chi-square value of at least 7.82.
Step-by-step explanation:
The value of the chi-square test statistic was 7.82 and the p- value is 0.02. This means that if the null hypothesis were true there is a 2 percent chance of obtaining a chi square value of at least 7.82
The p- value is defined as obtaining the test statistic under H0 as extreme as observed.
When the p- value is less than 0.05 in the chi square goodness fit test it means that the null hypothesis is rejected.
There fore option C is the best answer.
A)There is a 2 percent chance that the company's claim is correct.
B) There is a 2 percent chance of obtaining a chi-square value of at least 7.82.
C) If the null hypothesis were true, there is a 2 percent chance of obtaining a chi-square value of at least 7.82.
D) If the null hypothesis were true, there is a 2 percent chance that the company's claim is correct.
E) If the null hypothesis were true, there is a 2 percent chance of obtaining a chi-square value of 7.82.
The p-value is defined as obtaining the test statistic under H₀ as extreme as observed. Then the correct option is C.
What are null hypotheses and alternative hypotheses?In null hypotheses, there is no relationship between the two phenomenons under the assumption or it is not associated with the group. And in alternative hypotheses, there is a relationship between the two chosen unknowns.
The value of the chi-square test statistic was 7.82 and the p-value is 0.02. This means that if the null hypothesis were true if there is a 2% chance of obtaining a chi-square value of at least 7.82.
The p-value is defined as obtaining the test statistic under H₀ as extreme as observed.
Thus, the correct option is C.

Write the expression 5^2/3 without using exponents
The expression 5²/3 can be written without exponents as the fraction 25/3 or 8.33 approximately to 2 decimal place.
Whole numbers, exponents and fractionsWhole numbers include all natural numbers and 0 and can be expressed as exponents and fractions. Exponent is the method of expressing numbers in terms of powers while fractions a fraction represents a part of a whole or, more.
The expression 5²/3 having an exponent can be rewritten as follows:
5²/3 = (5 × 5)/3
5²/3 = 25/3

Find the value of x.
Answer:
x = 113
Step-by-step explanation:
Since the shape is a quadrilateral, the angles add up to 360 so:
x + 87 + 113 + 47 = 360
x + 247 = 360
x = 360 - 247
x = 113
