Answer: no they are not can you add me branliest plz

Step-by-step explanation: are The terms which have the same literal coefficients raised to the same powers but may only differ in numerical coefficient are called similar or like terms. The terms which do not have the same literal coefficients raised to the same powers are called dissimilar or unlike terms.

The system crosses at the point (3, 4). How many solutions will the system have?
vagabundo [1.1K]
For this case suppose that we have a linear system of equations of the form:
 ax + by = c
 dx + ey = f
 The solution of the system is an ordered pair of the form:
 (x, y)
 That is, both lines intersect at a point.
 The point of intersection in this case is:
 (3, 4)
 Therefore, the system has one solution.
 Answer
 
the system will have:
 
one solution

In the diagram below, ST is parallel to PQ. If ST is 4 more than PS,SR = 12, and PQ = 15, find the length of PS. Figures are not
Tpy6a [65]

Since segments ST and PQ are parallel, triangles SRT and PRQ are similar due to the AAA postulate. In general, the ratio between the corresponding sides of two similar triangles is constant; therefore,

\frac{SR}{PR}=\frac{RT}{RQ}=\frac{TS}{QP}

Furthermore,

PS=PR-RS

Finding PR and RS,

\begin{gathered} ST=4+PS \\ SR=12 \\ PQ=15 \end{gathered}

Then,

\frac{12}{PR}=\frac{TS}{15}\begin{gathered} \Rightarrow\frac{12}{PR}=\frac{4+PS}{15} \\ \Rightarrow\frac{12}{PS+12}=\frac{4+PS}{15} \end{gathered}

Solving for PS,

\begin{gathered} 12\cdot15=(PS+12)(PS+4) \\ \Rightarrow180=PS^2+16PS+48 \end{gathered}

Solve the quadratic equation in terms of PS, as shown below

\begin{gathered} \Rightarrow PS^2+16PS-132=0 \\ \Rightarrow PS=\frac{-16\pm\sqrt[]{16^2-4(-132)}}{2}=\frac{-16\pm28}{2} \\ \Rightarrow PS=-22,6 \end{gathered}

And PS is a segment; therefore, it has to be positive.

Hence, the answer is PS=6

the point B(-3, -2) is translated 4 units left. what are the coordinates of the resulting point, B’?
ololo11 [35]

Answer:

B'(-7 , -2)

Step-by-step explanation:

First we must understand the coordinate-axis, when we want to move a point to the left or right we do it on the x-axis. to move up or down is on the y axis.

now if we move to the left we go to the negative and to the right the positive

as we are going to move to the left we have to subtract the value that he gave us (4) only to the part of x

B(-3 , -2)

-3 - 4 = -7

B'( -7 , -2)

In decimal form, to the nearest tenth, what is the probability that a randomly selected Riverside High School student is in twel
Lunna [17]
We have that the total students there are 500. The 12-graders there are 200. Probability is defined as the ratio of positive outcomes of an event, over all the possible outcomes. Suppose we pick student randomly. Then, there are 200 positive outcomes (positive outcome: we pick a student in 12th grade) and there are totally 500 outcomes (we can pick 500 students in total from Riverside High School). This ratio gives: P= \frac{200}{500} =0.4. The requested probability is 0.40
