Answer:
y = -5x + 6
Step-by-step explanation:
General equation of a line : y = mx + c......where c is intercept
To find m pick any two points..
(-2, 16) and (-1, 11)
Using (y - y¹) / (x - x¹)
(11 - 16) / (-1 - [-2]) = -5 / 1
= -5
To find c sub with any point for (x, y) and m
using (2, -4)
y = mx + c
-4 = -5(2) + c
-4 = -10 + c
6 = c
Input the values of m and c in the general equation without x and y
; y = -5x + 6
Answer:
strawberry=7/8
Step-by-step explanation:
treat strawberry as x
add on proportions
1 1/8+ 3/4+ 1 3/4 + x = 4 1/2
(9+6+14)/8 + x = 9/2
29/8 +x = 9/2
x= 9/2 - 29/8
x= (36-29)/8
x=7/8
Answer:
a) PR = 17 cm, b) QR = 6 cm
Step-by-step explanation:
∠Q=90, so PQ and QR are legs, and PR is hypotenuse.
Pythagorean theorem PQ² + QR² = PR²
a) PQ² + QR² = PR²
8² + 15² = PR²
PR² = 289
PR = 17 cm
b) PQ² + QR² = PR²
8² + QR² = 10²
64 + QR² = 100
QR² = 36
QR = 6 cm
Answer
given,
352 + 116
we have to break 116 and use it on open number line
breaking of number 116
116 = 100 + 10 + 6
And addition will be shown in the number line attached below
now,
352 + 100 = 452
452 + 10 = 462
462 + 6 = 468
we know
sum of
352 + 116 = 468
