1 = slope intercept
<span>let x be the interval, then:
186 = 50 + 3 + (3+x) + (3+2x) + (3+3x) + (3+4x) + (3+5x) + (3+6x) + (3+7x)
186 = 74 + 28x
x = 4
Eldest son age = 3+7x = 3+28 = 31.</span>
Answer:
Step-by-step explanation:
first if you reflect an image its still identical think of it as a mirror its the same but on the other side. so if you flip it over the x or y axis it would just be as if you folded the paper and shape is on the other side. a rotation would be as if you moved the shape to another quadrant so if you move it 90 degres to the left it would be be turned slightly and a transformation if you slide it up the image is however many space it was from its current location. so each one moves it from its current location
Cosine is probably either opp/hyp or adj/hyp
Answer:
95.5°F
Step-by-step explanation:
Given the regression equation :
y = 1.8x - 76.9 ; the relationship between temperature (°F) and number of ice cream sold
y = number of ice cream sold
x = temperature (°F)
The temperature when 95 iccream cones are sold will be ;
Here, y = 95
Using the model :
95 = 1.8x - 76.9
95 + 76.9 = 1.8x
171.9 = 1.8x
Divide both sides by 1.8
171.9 / 1.8 = x
95.5°F = x
Hence, temperature when 95 cones of ice-cream are sold is 95.5°F
