Answer:
(3,5)
Step-by-step explanation:
Here we are asked to find the reflection of Point P(-1,5) along the line represented by x=1
Please refer to the image attached with answer.
We have point P (-1,5) , the line x=1 and the Point R which is the reflection of P across x=1
now we can see that P is 2 units towards left of the line x=1. hence its reflection across x=1 will be 2 units away towards right of line. 2 units away , the x coordinate will be 1+2 = 3
Hence the x coordinate is 3 and y coordinate remains the same. Hence the coordinates of R will be (3,5)
Answer:
x=0
Step-by-step explanation:
x^2-8x-2=0
x=±3√2−4
Answer:
3rd option
Step-by-step explanation:
-8 ≥ -5x + 2 > -38 subtract 2 from all three expressions
-10 ≥ -5x > -40 divide by 5
-2 ≥ -x > -8 now multiply by -1
2 ≤ x < 8
Answer:
The greatest common factor GCF is 15.
Step-by-step explanation:
Step 1:
The greatest common factor of the number is defined as the factor of two or more numbers. The acronym of Greatest common factor is GCF. Euclid’s algorithm is the method of finding greatest common factor between two numbers. Write the numbers in the linear form till zero comes in the remainder. Then a devisor will be the GCF of two numbers.
Step2
GCF (45, 75)
The greatest common factor of the two numbers 45 and 75 is calculated by Euclid’s algorithm as follows:
75=45\times1+30
45=30\times1+15
30=15\times2+0
Therefore, the greatest common factor GCF is 15.
